Pixels to Inches Calculator

Convert image pixel dimensions into a physical print size at a chosen pixel density (PPI). See inches, centimeters and millimeters, plus compare how the same image prints at common density settings.

Calculate print size

This estimates physical print dimensions from pixel dimensions and PPI. It does not change or resample the image file.

Print-size comparison

The table below compares the current image dimensions at common PPI values. Choose a preset above to make it the active setting.

PPI	Print size (inches)	Print size (cm)	Print size (mm)

Formula

Print width in inches = pixel width ÷ PPI
Print height in inches = pixel height ÷ PPI
Centimeters = inches × 2.54 · Millimeters = inches × 25.4

Worked example: 3000 × 2000 pixels at 300 PPI

Width: 3000 ÷ 300 = 10 inches. Height: 2000 ÷ 300 = approximately 6.67 inches. In metric units, the print is approximately 25.4 × 16.93 cm (254 × 169.33 mm), before any cropping or printer-specific scaling.

What PPI should I choose?

PPI means pixels per inch and describes how densely image pixels are mapped onto a physical print. Higher PPI makes a smaller print from the same pixel dimensions; lower PPI makes a larger print, but may look less detailed at close viewing distances. The appropriate setting depends on image detail, print size, viewing distance and the print provider's workflow.

People often say “DPI” when discussing print resolution, but DPI technically means dots per inch—the dots a printer lays down. PPI and printer DPI are related but are not interchangeable. Use the PPI requested by your print workflow when estimating image print size.

Frequently asked questions

Does changing PPI change the number of pixels?

No. This calculator only estimates the physical size at the selected density. Changing the PPI metadata or print setting alone does not add image detail or resample the pixels.

Why does a higher PPI make the print smaller?

The same number of pixels is packed into each inch, so more pixels per inch means fewer inches across and down.

Is 300 PPI always required?

No. 300 PPI is a common high-quality print target, but suitable density varies by printer, image, print dimensions and viewing distance. Follow your print provider's instructions when available.

Can I use this for screen dimensions?

This tool estimates physical print dimensions. For screen layouts, use pixel dimensions and aspect ratio; screen physical size and pixel density vary by device.
