24×36 Print Size in Pixels

A 24 × 36 inch print needs 7200 × 10800 pixels at 300 PPI. It measures 60.96 × 91.44 cm and has a 2:3 aspect ratio.

24 × 36 in at 300 PPI: 7200 × 10800 px (77.8 MP)

At 240 PPI: 5760 × 8640 px · at 150 PPI: 3600 × 5400 px

24×36 in pixels at each density

Multiply each inch dimension by the density. The results are exact because both sides are whole inches.

Calculate a canvas with your own settings

Your dimensions

On your device

Presets set the finished print size and unit. PPI and rounding remain your choice.

The desired finished width, before any bleed.

The desired finished height, before any bleed.

Applies to both dimensions.

Use your print provider’s requirement when available.

Nearest is a conventional approximation; round up meets at least the target PPI on both axes.

Use a decimal point, without commas. Physical lengths and PPI accept up to 4 decimal places.

Nearest-pixel rounding can fall slightly below the target on one axis. Use Round up when the target is a strict minimum.

This is the canvas size. Changing a file’s PPI metadata alone does not create these pixels.

Will my photo fit 24×36 without cropping?

24 × 36 inches is a common poster size with a 2:3 proportion. At large sizes, viewers usually stand farther away; ask your printer what density they recommend for the size.

How many megapixels does a 24×36 print need?

At 300 PPI the print needs 77.8 megapixels after any crop; at 240 PPI, 49.8 MP; at 150 PPI, 19.4 MP. These are arithmetic targets, not a promise of print quality: focus, noise and viewing distance matter too.

Changing an image’s PPI setting without resampling only changes its intended print size. Read what changing DPI actually does before upsizing a file.
