This is a question I've wondered about for some time. I'm interested to see what the averages are for displays people use to retrocompute.
My displays have averaged from about 212 to 220, with various monitors and televisions (never used an LCD). The current monitor I use displays about 220; It's a JVC BM-H1300SU Studio Monitor.
I'm not looking for exact numbers, obviously, since this poll just allows for even numbers to be selected. It's close enough for me.
Use the attached executable Atari image file to make your determination by getting your upper and lower numbers and then subtracting the upper from the lower for the total.
For those with quite curvy monitors, you can adjust your numbers accordingly to reflect visibility at full width if you like, but it's not necessary.
Selections are available for the various types and both NTSC and PAL: CRT Monitor (Real Monitors), LCD Monitor (of Any Type or Related Tech), and CRT Television. If you have monitors in multiple categories, you're welcome to enter as many as you'd like. If you'd like to post information about what monitor(s) you're using, that'd be cool too.
Altirra diplays 224 scanlines for NTSC and 240 for PAL, and these are the dimensions you'll get when saving a screenshot with Altirra.
