Common questions
What DPI do I need for printing?
300 DPI looks sharp when held in your hand. 200 to 240 DPI is good for most photos, and 150 DPI is fine for posters seen from a distance.
My photo says 72 DPI. Is it too low for printing?
Not necessarily. The DPI number in a file is just a label. What matters is how many pixels the image has: a 4000 × 3000 photo prints sharply on A4 whatever DPI it says.
How big can I print a 12 megapixel photo?
A 4032 × 3024 photo prints at 300 DPI up to about 34 × 26 cm, so A4 is excellent and A3 is still good.
