Question

Often I will create a winforms app and everything looks great when I run it. Then I go to a user’s computer and I see that labels are crunched, fonts are bigger and causing text to be cut off etc. What is going on? How can I prevent this?

I especially see this on newer windows OS’, i.e. Windows 7 etc. How can I make the form look the same (or at least good) for all users, on multiple windows OS versions?

Answer 1

If the UI is getting messed up because the fonts on the system are bigger or the DPI of the system is different from what you expected there are a couple of things you should do:

• do not use fixed coordinates and sizes
• do use docking and anchoring to position and size controls
• do use AutoSize to size controls according to their content
• do use Graphics.MeasureString() to calculate the size of strings instead of assuming a fontsize

EDIT

Of course it is also possible to distribute fonts (if legal) to make sure the correct/expected fonts are available but you will still need to anticipate various DPI settings.
