Consider setting a minimum size for the form.

Remarks

Forms that can be resized should generally have a minimum size set. The MinimumSize property allows you to limit the size of a form to prevent users from resizing the window to be too small.

(Note that this rule is ignored for MDI children.)

Resolution

Determine the minimum desirable window size, and set the form's Size property through the Windows Form Designer Properties window.
