Yes it is possible. Each form as a Height and Width property. You can determine the ration of height/width, change the height or the width then calculate the other using the ratio.

nRatio=ThisForm.Width/ThisForm.Height
ThisForm.Width=ThisForm.Width+50 && or shrink it by subtracting
ThisForm.Height=ThisForm.Width/nRatio

You could also set up this code in a separate UDF and call it from with the form to resize it.
