I do some of mine at about 12" across and 8" down, 300 dpi -- big enough for a book cover wraparound. If it's just a front cover, then I do it at 5.5" x 8", again 300 dpi. For the screen, when I set up the Bryce scene, that translates to maybe about 275 x 400 pixels (actually, bigger than that, but I'm too lazy to do the math; so long as it's the same aspect ratio, I'm good) for the front cover and about 900 x 600 pixels for the wraparound. Um. What does VS mean?
