How Big Can I Print an iPhone Photo?

A standard iPhone photo is 4032 × 3024 pixels (12.2 megapixels). That is enough for a sharp 8×10 or 11×14-style print, a good 16×20, and a wall-sized print at 150 PPI.

Largest print from 4032 × 3024, by quality level

Resolution	Largest print size	Quality
300 PPI	13.44 × 10.08 in	Excellent — close viewing
200 PPI	20.16 × 15.12 in	Good — normal distance
150 PPI	26.88 × 20.16 in	Acceptable — wall viewing

The maths is pixels ÷ PPI for each side: 4032 ÷ 300 = 13.44 in and 3024 ÷ 300 = 10.08 in at the highest quality tier.

What this means in practice

• 8×10: easily excellent — you have more pixels than the 2400 × 3000 needed at 300 PPI.
• 16×20: good. A full-frame iPhone shot gives about 189 PPI at this size (4032 ÷ 20 and 3024 ÷ 16, allowing for the crop to 5:4), just under the 200 PPI tier, which looks fine on a wall.
• 24×36 poster: below 150 PPI from a single standard iPhone frame (about 112 PPI on the long side), so expect a softer poster unless the shot is a high-resolution mode, panorama or stitched image.

Cropping, digital zoom, low light and sending a photo through messaging apps can all reduce the delivered pixel dimensions. Always check the file you will actually send to the printer — open its details and use those pixel numbers above, not the camera's headline megapixels.
