I assume you are talking about the kernel window operations like image filters. The size of the window depends on the purpose, how many minimum samples your kernel function needs and the object resolution of the image.

For example assume your image has small small circles of 5 x 5 pixel area. If your windows size is 5 x 5, in a smoothing operation using a mean function then those circles get smoothed. But if your window size is 10 x 10 then the circles may disappear. So it depends on the purpose whether you want remove the circles or not.

So the window size depends on purely specific purpose, a general rule may not work always.
