Low resolution screens hides some of the form

When I create Access databases I design on a monitor with very high
resolution so I can view multiple objects at once, but some of the users
have very low resolution so can't see an entire form, even when I have
thought I designed it small enough.
Is there a chart with some standard resolutions which will tell me what the
maximum width and height a form can be and still fit on the screen? I do
not interact with these users so can not measure things on their screens.
