Megapixels to Print Size Calculator
How big can you print a 12, 24 or 48 megapixel photo? Find the pixel dimensions and print sizes at different quality levels.
How to use the Megapixels to Print Size Calculator
- Enter the camera’s megapixels.
- Choose the image aspect ratio.
- Read the print sizes at 300, 240 and 150 DPI.
How it works
The calculator works out the image width and height from megapixels and aspect ratio, then divides by the print resolution. 300 DPI gives excellent detail at close range; 240 DPI is hard to tell apart for most prints, and 150 DPI works for large posters viewed from a distance. A 24 MP (6000 × 4000) photo prints 20 × 13.3 in at 300 DPI.
