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)')

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

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 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

Jonas s answer is good  but I had to modify it slightly to get every piece of text on the screen to change   set gca  FontSize  30  fontWeight   bold    set findall gcf  type   text    FontSize  30  fontWeight   bold

Jonas s answer does not change the font size of the axes   Sergeyf s answer does not work when there are multiple subplots    Here is a modification of their answers that works for me when I have multiple subplots   set findall gcf  type   axes    fontsize  30  set findall gcf  type   text    fontSize  30
