How to use this tool
- Enter your image's width and height in pixels (check your image editor or file properties).
- Enter the target DPI — 300 is standard for photo-quality prints, 150 for large posters viewed from a distance, 72 for screens.
- Read the resulting print size in inches and centimeters.
DPI (dots per inch) tells a printer how densely to pack pixels onto paper. The same image file prints at a different physical size depending on the DPI you choose — enter your image's pixel dimensions and target DPI to see exactly how large (or small) it will print.

Frequently asked questions
- What DPI should I use for printing?
- 300 DPI is the standard for high-quality photo and document printing viewed up close. Large-format prints like posters or banners, viewed from farther away, can use 150 DPI or even lower without looking soft.
- Why does a 600 DPI image print smaller than a 72 DPI image with the same pixel count?
- Higher DPI packs more pixels into each inch of paper, so the same pixel dimensions cover a smaller physical area. A 3000×2000px image is 10×6.7 in at 300 DPI but 41.7×27.8 in at 72 DPI.
