Questions and answers
How many megapixels do I need for a print?
For a sharp 4 × 6 inch print about 2 megapixels are enough, for A4 or 8 × 10 inches about 8 megapixels, and for A3 about 17 megapixels, at 300 pixels per inch.
Are more megapixels always better?
More pixels allow larger prints and tighter crops, but sharpness also depends on the lens, focus and light. A blurry 48 MP photo still looks blurry.
