Photo Print Sizes in Pixels

Choose a physical size and a planning density. Each value is calculated from the exact inch dimensions; the table does not add bleed or account for a crop.

Portrait width × height. Rotate both dimensions for landscape. PPI values are comparisons, not quality guarantees.

How to read this chart

Multiply each physical dimension in inches by the target pixels per inch. An 8 × 10 print at 300 PPI needs 2400 × 3000 pixels. At 240 PPI the same physical size needs 1920 × 2400 pixels. These results describe a rectangular canvas with the exact target shape.

Check your source ratio first

A 3000 × 2000 landscape photo does not match an 8 × 10 portrait opening. The usable pixels after a fill crop matter more than the full source count. Open the image checker to compare the crop with a fit placement that preserves the full image.

Use the provider’s actual requirement for your product. The table does not determine sufficient image detail, add bleed or establish printer support for a listed size.
