Check how large an image can print

Print quality depends on both pixel dimensions and DPI. This calculator converts image width and height into print sizes at common DPI settings.

Use it for posters, product sheets, photography prints, documents, and marketplace print guidelines.

Frequently asked questions

What DPI is best for photo printing?

300 DPI is a common high-quality print target. 150 to 240 DPI can still work depending on viewing distance.

How do I convert pixels to inches?

Divide pixel width or height by DPI. For example, 3000 pixels at 300 DPI prints at 10 inches.

Does changing DPI change image quality?

Changing DPI metadata alone does not add detail. The actual pixel dimensions determine available detail.

Plan the image, then improve it

Use free calculators for sizing and compression decisions, then use Photo Cut tools when the image needs AI cleanup, watermark removal, logo removal, or smarter compression.
