Poster 1 — This one would be great for class handouts. It's 8.5" x 11". Medium-resolution jpeg (150 dpi).

Poster 2 — For higher quality, larger printouts. This one is 11" x 14". High-resolution jpeg (300 dpi).

Poster 3 — A good size for classroom displays: 24" x 31". This medium-resolution jpeg (150 dpi) will require a large-output printer.
