How to use the pixels to print size converter
Use this when a file is already in hand and the open question is how large it can be printed. Enter the width and height in pixels plus a print resolution in DPI, and the page converts that into a physical size in inches, cm and mm, then reports the largest print that still meets a required minimum DPI you set separately. Total pixels and megapixels appear in the table too.
The formula is short: size in inches = pixels divided by DPI, and cm is that figure times 2.54. Printing 2000 px at 300 DPI gives 6.67 inches, about 16.93 cm. Treating 300 DPI as the bar for general printing is an industry convention rather than a standard, so lower it for output viewed from a distance, such as a banner (convention as of October 2026). A Letter sheet at 8.5 by 11 inches is a handy sanity check.
This page runs in one direction only, from pixels to a physical size. The reverse, working out how many pixels a desired physical size at a given DPI requires, is covered by the Simplewoody DPI to pixel calculator. Paper size tables, bleed margins and color profile conversion are out of scope, so confirm those requirements with your printer separately.
Frequently asked questions
It is a widely used convention for general printing rather than a standard, which is why it sits in an editable field. Large output viewed from a distance is fine at lower values.
This page does not do that. A separate Simplewoody tool goes the other way, from a physical size and a DPI to the pixels required, so use that one.
Because the resolution you actually print at and the quality bar you are held to can differ. Splitting them lets you see both whether this size falls short and how large you could go while still clearing the bar.
