I'm using this function for a pop up window for users to enter text.
"prompt = {'Enter Serial Number:'}; Title = 'Attention!'; defaultans = {''}; x = inputdlg(prompt,Title,[1 35]);"
What is the best way to increase font size of the Title/Prompt text? I also would like to change pop window color and size.

They've known about the lame capabilities of msgbox(), questdlg(), warndlg(), errordlg(), inputdlg() for ages and they've never chosen to enhance them so I guess they just don't want to, despite being a pain to the users for decades. I know other functions like title(), text(), xlabel(), etc. have options like 'FontSize', 'FontWeight', 'ForegroundColor', etc. but for some reason unknown to me they don't seem to want to offer those options to dialog boxes that ask for user input.
If you start GUIDE, one of the options is a custom dialog box where you have complete control over all of that, so I guess that's how they want you to do it. I know it seems like an overly complicated way to do a simple dialog box, but that seems to be what they want us to do. Grrrrrr.

The msgbox() was straight forward and easy, Well looks like I'll have to try the GUIDE!!! Thanks for the feedback.
In case others were looking for a solution, here's a function that receives the msgbox handle and a fontsize. I got tired of squinting. You can also set any other text property.

How about this?
prompt = {'\fontsize{15} Enter Serial Number:'};
Title = 'Attention!';
defaultans = {''};
opts.Interpreter = 'tex';
x = inputdlg(prompt,Title,[1 35], defaultans, opts);
You can specify the font size of the text in the input dialog with TeX syntax.

Kudos on your answer. However, it only increases the font of the prompts, not the defaults or the buttons.
