Add New Font
You can install new fonts to use with MATLAB. A common reason to install additional fonts is to read files created
in different languages. For details on adding fonts to your system, refer to the
documentation for your system.
Choose a new font that is compatible with MATLAB. MATLAB only includes compatible fonts in the font preferences.
-
For desktop components (such as the Command Window), figure windows, and
uicontrols, fonts must be compatible with TrueType and Microsoft
OpenType® fonts -
For graphics objects, such as
xlabel,
ylabel,title, and
text, fonts must be TrueType and Microsoft
OpenType fonts
Install your new font in a location where MATLAB looks for fonts. MATLAB looks for fonts in these locations:
-
The operating system’s standard location (see your system administrator
for details) -
The
/jre/lib/fontsfolder where Java® software is installed on your system
If you install a font with MATLAB running, restart MATLAB to include the font in the font preferences.
Then, to use the new font, follow the instructions in Change Font Name and Style.

fontsize
Change font size for objects in a figure
Syntax
Description
example
fontsize(obj,size,units)
sets the font size and font units for all of the text within graphics object
obj. If obj contains other graphics objects, such as
a figure that contains UI components or an axes object that has a legend,
fontsize also sets the font size and font units for those objects
within obj. Font units can be "points",
"pixels", "inches", or
"centimeters".
example
fontsize(obj,"increase")
increases the font size by a factor of 1.1.
fontsize(obj,"decrease")
decreases the font size by a factor of 0.9.
example
fontsize(obj,scale=sfactor)
scales the font size by a factor of sfactor. For example, use a scale
factor of 1.2 to scale by 120%.
example
fontsize(obj,"default")
resets the font size and font units back to the default, automatic values for
obj.
Examples
collapse all
Change Font Size of Plot Text
Create a plot of random data, and add a plot title and legend.
y = rand(5); plot(y) title("2-D Line Plot") legend("Line 1","Line 2","Line 3","Line 4","Line 5")
Set the font size of all text within the axes object to 10 and the font units to "pixels". Use the object returned by gca as the target object to apply this change.
fontsize(gca,10,"pixels")
Scale Font Size of Text in Figure
Create a plot with several text elements of varying font sizes.
[X,Y,Z] = peaks; contourf(X,Y,Z,LineColor="#4F4F4F") title("Peak Elevation") colorbar annotation("textarrow",[.53 .41],[.65 .47],String="Local maxima") annotation("textarrow",[.53 .59],[.65 .55])
Scale the font sizes in the figure by 120% by using a scale factor of 1.2. The fontsize function scales each font size individually, maintaining the relative sizes of the fonts.
Change Font Size in Tiled Chart Layout
Create a tiling of several plots by using the tiledlayout and nexttile functions.
x = linspace(0,3*pi,200); y = cos(x) + rand(1,200); t = tiledlayout(2,2); % Top scatter plot in tiles 1,2 ax1 = nexttile([1 2]); scatter(x,y) title("Random Variance on Cosine") % Lower polar plot in tile 3 ax2 = nexttile; plot(x,cos(x)+0.5) % Lower histogram in tile 4 ax3 = nexttile; histogram(y,20)
Scale up the font size of the scatter plot, and change the font size of the other two plots to 10 pixels.
fontsize(ax1,scale=1.2)
fontsize([ax2 ax3],10,"pixels")
To undo the font size changes across all the tiled plots, reset the font sizes and units to their default values. Apply this change to all three plots by using the current figure object returned by gcf.
Change Font Size of App Text
Create the following function file, and save it as myapplayout.m on your MATLAB® path. This function returns the layout for a simple app to plot data using different plot types.
function fig = myapplayout % Create figure window fig = uifigure; % Create UI components ax = uiaxes(fig,Position=[15 70 535 340]); lbl = uilabel(fig,Position=[30 15 100 35],Text="Choose Plot Type:"); b1 = uibutton(fig,Position=[140 15 180 35],Text="Surf"); b2 = uibutton(fig,Position=[350 15 180 35],Text="Mesh"); % Configure UI component appearance surf(ax,peaks); fontsize(fig,8,"pixels") title(ax,"Peak Surface",FontSize=11) end
Call the function and assign the returned figure object to f.
![{"String":"Figure contains an axes object and other objects of type uilabel, uibutton. The axes object with title Peak Surface contains an object of type surface.","Tex":"Peak Surface","LaTex":[]}](https://www.mathworks.com/help/examples/matlab/win64/ChangeFontSizeOfAppTextExample_01.png)
Use f to increase the font size of all text in the figure until it is more easily readable. Here, the fontsize function increases each font size individually by a scale factor of 1.1, maintaining the relative sizes of the fonts.
fontsize(f,"increase") fontsize(f,"increase") fontsize(f,"increase")
![{"String":"Figure contains an axes object and other objects of type uilabel, uibutton. The axes object with title Peak Surface contains an object of type surface.","Tex":"Peak Surface","LaTex":[]}](https://www.mathworks.com/help/examples/matlab/win64/ChangeFontSizeOfAppTextExample_02.png)

Text to display, specified as a character vector, cell array of character vectors,
string array, categorical array, or numeric value. Specify a value according to how you
want the text to appear. This table lists the most common situations.
| Appearance of Text | Description of Value | Example |
|---|---|---|
| One line of text | Character vector or 1-by-1 string array. |
str = 'My Text'
or str = "My Text"
|
| Multiple lines of text | Cell array of character vectors or a string array. |
str = {'First line','Second line'};
or str = ["First line", "Second line"]; |
| Text that includes a numeric variable | Array that includes the number converted to achar array. Use num2str to convertthe value. |
x = 42;
str = ['The value is ',num2str(x)];
|
| Text that includes special characters such as Greek letters or mathematical symbols |
Array that includes TeX markup. For a list of supported markup, see the Interpreter property. |
str = 'x ranges from 0 to 2pi'
|
Note
-
The words
default,factory, and
removeare reserved words that do not appear in text
when quoted as normal characters. To display any of these words
individually, precede them with a backslash, such as
'default'or'remove'. -
If you specify this property as a categorical array, MATLAB® uses the values in the array, not the categories.
-
If you specify text that contains only a numeric value, the value is
converted usingsprintf('%g',value). For example,
12345678displays as
1.23457e+07.
Text color, specified as an RGB triplet, a hexadecimal color code, a color name, or a short
name. The default value of [0 0 0] corresponds to black.
For a custom color, specify an RGB triplet or a hexadecimal color code.
-
An RGB triplet is a three-element row vector whose elements
specify the intensities of the red, green, and blue
components of the color. The intensities must be in the
range[0,1], for example,[0.4.
0.6 0.7] -
A hexadecimal color code is a character vector or a string
scalar that starts with a hash symbol (#)
followed by three or six hexadecimal digits, which can range
from0toF. The
values are not case sensitive. Therefore, the color codes
"#FF8800",
"#ff8800",
"#F80", and
"#f80"are equivalent.
Alternatively, you can specify some common colors by name. This table lists the named color
options, the equivalent RGB triplets, and hexadecimal color codes.

-
'tex'— Interpret characters using a subset of
TeX markup. -
'latex'— Interpret characters using LaTeX
markup. -
'none'— Display literal characters.
TeX Markup
By default, MATLAB supports a subset of TeX markup. Use TeX markup to add superscripts
and subscripts, modify the font type and color, and include special characters in
the text.
Modifiers remain in effect until the end of the text.
Superscripts and subscripts are an exception because they modify only the next character or the
characters within the curly braces. When you set the interpreter to 'tex',
the supported modifiers are as follows.
| Modifier | Description | Example |
|---|---|---|
^{ } |
Superscript | 'text^{superscript}' |

LaTeX Markup
To use LaTeX markup, set the interpreter to 'latex'. For inline
mode, surround the markup with single dollar signs ($). For
display mode, surround the markup with double dollar signs
($$).
| LaTeX Mode | Example | Result |
|---|---|---|
| Inline |
'$int_1^{20} x^2 dx$'
|
|
| Display |
'$$int_1^{20} x^2 dx$$'
|
|
The displayed text uses the default LaTeX font style. The
FontName, FontWeight, and
FontAngle properties do not have an effect. To change the
font style, use LaTeX markup.
The maximum size of the text that you can use with the LaTeX interpreter is 1200
characters. For multiline text, this reduces by about 10 characters per line.
For examples that use TeX and LaTeX, see Greek Letters and Special Characters in Chart Text. For more information about the LaTeX
system, see The LaTeX Project website at https://www.latex-project.org/.
Font

Font name, specified as a supported font name or 'FixedWidth'. To display
and print text properly, you must choose a font that your system supports. The default
font depends on your operating system and locale.
To use a fixed-width font that looks good in any locale, use 'FixedWidth'.
The fixed-width font relies on the root FixedWidthFontName
property. Setting the root FixedWidthFontName property causes an
immediate update of the display to use the new font.
Font size, specified as a scalar value greater than 0 in point units. The default font size
depends on the specific operating system and locale. One point equals 1/72 inch. To
change the font units, use the FontUnits property.
Example: 12
Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical
Character thickness, specified as 'normal' or
'bold'.
MATLAB uses the FontWeight property to select a font from
those available on your system. Not all fonts have a bold weight. Therefore, specifying
a bold font weight can still result in the normal font weight.
Character slant, specified as 'normal' or
'italic'.
Not all fonts have both font styles. Therefore, the italic font might look the same
as the normal font.
FontUnits — Font size units
'points' (default) | 'inches' | 'centimeters' | 'normalized' | 'pixels'
Font size units, specified as one of the values in this
table.
Units |
Description |
|---|---|
'points' |

'normalized'
|
Interpret font size as a fraction of the parent container height, typically a figure. If you resize the container, the font size modifies accordingly. For example, if the FontSize is0.1 in normalized units, then thetext is 1/10 of the container height. |
'pixels' |
Pixels. Starting in R2015b, distances in pixels are
On Linux® systems, the size of a pixel is |
If you set both the font size and the font units in one function call, you
must set the FontUnits property first so that the axes
correctly interprets the specified font size.
Text Box
expand all
FitBoxToText — Option to fit box width and height to text
'on' (default) | on/off logical value
Option to fit the box width and height to the text, specified as
'on' or 'off', or as numeric or
logical 1 (true) or
0 (false). A value of
'on' is equivalent to true, and
'off' is equivalent to false.
Thus, you can use the value of this property as a logical value. The value
is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.
-
'on'— Resize the text box to fit
the text. -
'off'— Wrap the text to fit the
width of the text box. Wrapping can cause some of the text to
extend below the text box.
If you resize a text box when in plot edit mode, or if you
change the Position property, then the
FitBoxToText property changes to
'off'.
EdgeColor — Color of box outline
[0 0 0]
(default) | RGB triplet | hexadecimal color code | 'r' | 'g' | 'b' | …
Color of box outline, specified as a three-element RGB triplet, a
hexadecimal color code, a color name, or a short name. The default value of
[0 0 0] corresponds to black.
For a custom color, specify an RGB triplet or a hexadecimal color code.
-
An RGB triplet is a three-element row vector whose elements
specify the intensities of the red, green, and blue
components of the color. The intensities must be in the
range[0,1], for example,[0.4.
0.6 0.7] -
A hexadecimal color code is a character vector or a string
scalar that starts with a hash symbol (#)
followed by three or six hexadecimal digits, which can range
from0toF. The
values are not case sensitive. Therefore, the color codes
"#FF8800",
"#ff8800",
"#F80", and
"#f80"are equivalent.
Alternatively, you can specify some common colors by name. This table lists the named color
options, the equivalent RGB triplets, and hexadecimal color codes.

Margin — Space around text within the text box
5 (default) | scalar numeric value
The space around the text within the text box, specified as a scalar
numeric value in pixel units.
Position
expand all
Position — Size and location
[0.3 0.3 0.1 0.1] (default) | four-element vector
Size and location, specified as a four-element vector of the form
[x_begin y_begin length height]. The first two
elements specify the coordinates for the lower-left corner of the text box.
The second two elements specify the length and height of the text
box.
By default, the units are normalized to the figure. The lower-left corner
of the figure maps to (0,0), and the upper-right corner
maps to (1,1). To change the units, use the
Units property.
Note
If the FitBoxToText property is set to
'on' and you change the String
property, then the Position property might not
reflect the latest changes until the next time the screen refreshes. To
ensure that the position value reflects the latest changes, call
drawnow before querying the position when working
in a script or function.
Example: [0.2 0.3 0.4 0.5]
Rotation — Rotation angle in degrees
0 (default) | scalar numeric value
Rotation angle in degrees, specified as a scalar numeric value. Rotation angle is absolute
and not relative to previous rotations.
This table shows the resulting annotation rotation for the possible
Rotation values.
| Rotation Value | Resulting Rotation |
|---|---|
| 0 | Unrotated |
| Positive scalar value | Rotated counterclockwise by the specified number of degrees |
| Negative scalar value | Rotated clockwise by the specified number of degrees |
The anchor point for rotation is the location specified by the first two elements of the
Position property vector, indicated by the [x y]
values.

window.
This property affects the Position property.
If you change the units, then it is good practice to return it to
the default value after completing your computation to prevent affecting
other functions that assume Units is set to the
default value.
If you specify the Position and Units properties
as Name,Value pairs when creating the object, then
the order of specification matters. If you want to define the position
with particular units, then you must set the Units property
before the Position property.

-
'tex'— Interpret characters using a subset of
TeX markup. -
'latex'— Interpret characters using LaTeX
markup. -
'none'— Display literal characters.
TeX Markup
By default, MATLAB supports a subset of TeX markup. Use TeX markup to add superscripts
and subscripts, modify the font type and color, and include special characters in
the text.
Modifiers remain in effect until the end of the text.
Superscripts and subscripts are an exception because they modify only the next character or the
characters within the curly braces. When you set the interpreter to 'tex',
the supported modifiers are as follows.
| Modifier | Description | Example |
|---|---|---|
^{ } |

Text Box

FitBoxToText — Option to fit box width and height to text
'on' (default) | on/off logical value
Option to fit the box width and height to the text, specified as
'on' or 'off', or as numeric or
logical 1 (true) or
0 (false). A value of
'on' is equivalent to true, and
'off' is equivalent to false.
Thus, you can use the value of this property as a logical value. The value
is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.
-
'on'— Resize the text box to fit
the text. -
'off'— Wrap the text to fit the
width of the text box. Wrapping can cause some of the text to
extend below the text box.
If you resize a text box when in plot edit mode, or if you
change the Position property, then the
FitBoxToText property changes to
'off'.
EdgeColor — Color of box outline
[0 0 0]
(default) | RGB triplet | hexadecimal color code | 'r' | 'g' | 'b' | …
Color of box outline, specified as a three-element RGB triplet, a
hexadecimal color code, a color name, or a short name. The default value of
[0 0 0] corresponds to black.
For a custom color, specify an RGB triplet or a hexadecimal color code.
-
An RGB triplet is a three-element row vector whose elements
specify the intensities of the red, green, and blue
components of the color. The intensities must be in the
range[0,1], for example,[0.4.
0.6 0.7] -
A hexadecimal color code is a character vector or a string
scalar that starts with a hash symbol (#)
followed by three or six hexadecimal digits, which can range
from0toF. The
values are not case sensitive. Therefore, the color codes
"#FF8800",
"#ff8800",
"#F80", and
"#f80"are equivalent.
Alternatively, you can specify some common colors by name. This table lists the named color
options, the equivalent RGB triplets, and hexadecimal color codes.

FaceAlpha — Transparency of background color
1 (default) | scalar value between 0 and 1 inclusive
Transparency of the background color, specified as a scalar value between
0 and 1. If the value is 1, then the color is opaque. To add transparency,
set the property to a value closer to 0, where 0 is completely
transparent.
LineStyle — Line style of box outline
'-' (default) | '--' | ':' | '-.' | 'none'
Line style of box outline, specified as one of the options listed in this

'-' |
Solid line |
'--' |
Dashed line |
':' |
Dotted line |
'-.' |
Dash-dotted line |

Box outline is invisible |
LineWidth — Width of box outline
0.5 (default) | scalar numeric value
Width of box outline, specified as a scalar numeric value in
point units. One point equals 1/72 inch.
Example: 1.5
Margin — Space around text within the text box
5 (default) | scalar numeric value
The space around the text within the text box, specified as a scalar
numeric value in pixel units.
Position
expand all
Position — Size and location
[0.3 0.3 0.1 0.1] (default) | four-element vector
Size and location, specified as a four-element vector of the form
[x_begin y_begin length height]. The first two
elements specify the coordinates for the lower-left corner of the text box.
The second two elements specify the length and height of the text
box.
By default, the units are normalized to the figure. The lower-left corner
of the figure maps to (0,0), and the upper-right corner
maps to (1,1). To change the units, use the
Units property.
Note
If the FitBoxToText property is set to
'on' and you change the String
property, then the Position property might not
reflect the latest changes until the next time the screen refreshes. To
ensure that the position value reflects the latest changes, call
drawnow before querying the position when working
in a script or function.
Example: [0.2 0.3 0.4 0.5]
Rotation — Rotation angle in degrees
0 (default) | scalar numeric value
Rotation angle in degrees, specified as a scalar numeric value. Rotation angle is absolute
and not relative to previous rotations.
This table shows the resulting annotation rotation for the possible
Rotation values.
| Rotation Value | Resulting Rotation |
|---|---|
| 0 | Unrotated |
| Positive scalar value | Rotated counterclockwise by the specified number of degrees |
| Negative scalar value | Rotated clockwise by the specified number of degrees |
The anchor point for rotation is the location specified by the first two elements of the
Position property vector, indicated by the [x y]
values.
Example: 45
Position units, specified as one of the values in this table.
Units |
Description |
|---|---|
'normalized' (default) |
Normalized with respect to the figure, uipanel, or uitab that contains the annotation. The lower-left corner of the container maps to (0,0) and the upper-right corner maps to (1,1). |
'inches' |
Inches. |
'centimeters' |
Centimeters. |
'characters' |
Based on the default system font character size.
|
'points' |
Points. One point equals 1/72 inch. |
'pixels' |
Pixels. Starting in R2015b, distances in
On Linux systems, the size of a pixel is determined |
All units are measured from the lower-left corner of the figure
window.
This property affects the Position property.
If you change the units, then it is good practice to return it to
the default value after completing your computation to prevent affecting
other functions that assume Units is set to the
default value.
If you specify the Position and Units properties
as Name,Value pairs when creating the object, then
the order of specification matters. If you want to define the position
with particular units, then you must set the Units property
before the Position property.
Horizontal alignment of the text within the text box, specified
as one of the values in this table.
| Value | Result |
|---|---|
'left' |
|
'center' |
|
'right' |
|
Vertical alignment of the text within the text box, specified
as one of the values in this table.
| Value | Result |
|---|---|
'top' |
|
'middle' |
|
'bottom' |
|
Note
The 'cap' and 'baseline' values
are not recommended. Use the 'top' and 'bottom' values,
respectively, instead.

R2022a: Rotate annotation
Rotate the annotation the specified number of degrees using the
Rotation property. The anchor point for rotation is the location
specified by the Position property, so the
Position property is unaffected by rotation.

If you want to change font size for all the text in a figure, you can use findall to find all text handles, after which it’s easy:
figureHandle = gcf;
%# make all text in the figure to size 14 and bold
set(findall(figureHandle,'type','text'),'fontSize',14,'fontWeight','bold')

It’s possible to change default fonts, both for the axes and for other text, by adding the following lines to the startup.m file.
% Change default axes fonts.
set(0,'DefaultAxesFontName', 'Times New Roman')
set(0,'DefaultAxesFontSize', 14)
% Change default text fonts.
set(0,'DefaultTextFontname', 'Times New Roman')
set(0,'DefaultTextFontSize', 14)
If you don’t know if you have a startup.m file, run
which startup
to find its location. If Matlab says there isn’t one, run
userpath
to know where it should be placed.

If anyone was wondering how to change the font sizes without messing around with the Matlab default fonts, and change every font in a figure, I found this thread where suggests this:
set(findall(fig, '-property', 'FontSize'), 'FontSize', 10, 'fontWeight', 'bold')
findall is a pretty handy command and in the case above it really finds all the children who have a 'FontSize' property: axes lables, axes titles, pushbuttons, etc.
Hope it helps.

To change the default property for your entire MATLAB session, see the documentation on how default properties are handled.
As an example:
set(0,'DefaultAxesFontSize',22)
x=1:200; y=sin(x);
plot(x,y)
title('hello'); xlabel('x'); ylabel('sin(x)')

Если вы хотите изменить размер шрифта для всего текста на рисунке, вы можете использовать findall, чтобы найти все текстовые дескрипторы, после чего легко:
figureHandle = gcf;
%# make all text in the figure to size 14 and bold
set(findall(figureHandle,'type','text'),'fontSize',14,'fontWeight','bold')

Можно изменить шрифты по умолчанию, как для осей, так и для другого текста, добавив следующие строки в файл startup.m.
% Change default axes fonts.
set(0,'DefaultAxesFontName', 'Times New Roman')
set(0,'DefaultAxesFontSize', 14)
% Change default text fonts.
set(0,'DefaultTextFontname', 'Times New Roman')
set(0,'DefaultTextFontSize', 14)
Если вы не знаете, есть ли файл startup.m, запустите
which startup
чтобы найти его местоположение. Если Matlab говорит, что его нет, запустите
userpath
чтобы узнать, где он должен быть размещен.

Если кто-то задавался вопросом, как изменить размер шрифта, не вмешиваясь в шрифты по умолчанию Matlab и изменить каждый шрифт на фигуре, я нашел эта нить, где предлагает это:
set(findall(fig, '-property', 'FontSize'), 'FontSize', 10, 'fontWeight', 'bold')
findall — довольно удобная команда, и в приведенном выше случае он действительно находит всех детей, у которых есть свойство 'FontSize': осями, названиями осей, кнопками и т.д.
Надеюсь, что это поможет.

This has been tested with Matlab R2015a on Linux, but I’d expect it to work on other platforms and maybe earlier versions, too.
Matlab’s documentation is in the form of HTML, and the help browser is basically a web browser displaying locally stored files. There are several central style files, but the most important one appears to be
/opt/MATLAB/R2015a/help/includes/product/css/reset.css
Open this file (as root / administrator) in a text editor, and append the line
html { zoom: 1.5; }
Adjust the number to your liking.

for R2014a, in /opt/MATLAB/R2015a/help/includes/product/css/reset.css, alter the value in the field
font-size:100%
to your liking. start with 105% — it’s sensitive.
Note that you don’t have to restart Matlab, just close the help window and re-open after you save the file. You can iterate quickly to find your desired zoom.
