How big can you print a 50 megapixel photo?

A 50 megapixel photo is about 8,660 × 5,774 pixels. At 300 DPI it prints 28.9 × 19.2 inches (73 × 49 cm) with no upscaling.

Megapixels are the pixels along the width multiplied by the pixels along the height, in millions. How large that prints depends on how many of those pixels you put in each inch: 300 for a print held in the hand, fewer for one on a wall.

What the table assumes

Exact pixel sizes vary by camera: one maker’s 50 megapixels may be a few dozen pixels wider or narrower than another’s. The sizes here are no upscaling and no cropping. “Sharp from” is the distance at which someone with 20/20 vision stops seeing separate pixels; a large print on a wall is normally looked at from further back than that, which is why posters can use far fewer than 300 pixels to the inch.
