8x10 - 1600x1200 minimum

5x7 - 1280x960 minimum

4x6 - 1024x768 minimum

minimum is 150 pixels per inch, so, if you want a 1x1" image, it's 150x150 pixels, and 3x5" is 450x750 pixels.

However, normal printing (like magazines) is at 300 or 350 (depending on the press being used) pixels/inch.

so, for quality prints, you really want 300 pixels/inch.
