I have a small form that displays some progress information.
Very rarely I have to show a rather long message and I want to be able to resize this form when needed so that this message fits in the form.
So how do I find out how wide string S will be rendered in font F?

A font is often measured in pt (points). Points dictate the height of the lettering. There are approximately 72 (72.272) points in one inch or 2.54 cm. For example, the font size 72 would be about one inch tall, and 36 would be about a half of an inch.
Python has a method called len() that gives us the length of any composite object. To get the length of a string, just pass the string to the len() call.
if the html element has inline style, you can using the . style. fontSize to get the font-size!
It depends on the rendering engine being used. You can basically switch between GDI and GDI+. Switching can be done by setting the UseCompatibleTextRendering property accordingly
When using GDI+ you should use MeasureString:
string s = "A sample string";
SizeF size = e.Graphics.MeasureString(s, new Font("Arial", 24));
When using GDI (i.e. the native Win32 rendering) you should use the TextRenderer class:
SizeF size = TextRenderer.MeasureText(s, new Font("Arial", 24));
