Olympus has a great page for consumers to understand pixel-print size relationship: http://www.olympus.co.uk/consumer/208_741.htm http://www.olympus.co.uk/consumer/208_741.htm For example, my D300s (12M) at 4288x2848 pixels can be printed at 300dpi (professional photo prints) at a maximum size of 14.3x9.5(inch) = 36.32x24.13(cm) = a little bit smaller than an A3. The same picture can be printed @150 dpi on an A1 (84.10 cm x 59.40 cm) leaving a little bit of border.
