Use the 'FontSize' property of the current axes:


Yep for me it works also; i.e. it does the same as @Star Strider. Please see my comment below. OF course I used dummy values for the ticks and titles font size, but you can resize the title after changing the ticks if you like.
Example code:
x = 1:6*pi;
title('This is sin(x) vs x');
outputs this:
What you can do if you want to change the size of the title is assigning it a handle and modify its "FontSize" property directly:
hTitle = title('This is sin(x) vs x');
Be sure to add the title before setting font size. If you change font size then add the title it will be in the font size you just set. Though you can change it again afterwards.

If you search for 'tick labels' or something similar, in the file exchange there are numerous options that replace the tick labels locked into the axes font size with text objects that can be manipulated independently.
I can't vouch for any particular one as I have never used any of them though.
