Resolution handling between platforms?

[J__]

Hi,

I have a little database, which I run on Mac OSX - on a Powerbook.. i think it's 1168x9 - sorry can't remember the rest not near my pbook right now. Then I have a pc which i is 1024X768. Everything on the windows side appears bigger.

to the point that what fit nicely on the mac os x screen in one page, now requires scrolling.

how should I handle this so that I do not have to write a different layout for each platform?

thanks,

J__
