For a while I was wondering if there was a good way to compare the sizes of various screens in my life, from my projector's pulldown screen in my living room, to my monitor at home, to what I get when I go to the movies. I know that the important thing wasn't the physical size of the screen, but a factor of that and how far away you're sitting from it...how many degree degrees of my personal viewspace a screen fills. I couldn't think if a convenient way of measuring that, until the other day: I extend my hand directly in front of my face as if I was thumbing my nose at the screen, then put the pointer finger of my ohter hand perpendicular to the pinky, and line that up against the corner of the screen. I can then get a width or height measured in "finger". It's not an exact science, but it's pretty good.
