Pixels Converter

Pixels Converter turns a pixel value into a real-world size — and back again — in a single tap. Enter a number, pick the units, set your resolution, and read the answer instantly in inches, centimeters, millimeters, points, picas and em. It works completely offline and nothing you type ever leaves your phone.

WHY RESOLUTION MATTERS

A pixel is one dot on a screen, not a fixed physical length. To turn pixels into a real size you need the resolution — the dots per inch (DPI) or pixels per inch (PPI). Pixels Converter puts that front and center: change the DPI and every pixel result updates, because the same physical size is more pixels on a high-DPI screen and fewer on a low-DPI one.

THE MATH

Once you fix the resolution, every unit is related through the inch:

- 1 inch = DPI pixels

- 1 inch = 2.54 cm = 25.4 mm

- 1 inch = 72 points (pt)

- 1 inch = 6 picas

- 1 em = your base font size in pixels

So at 96 DPI, 96 px = 1 inch = 2.54 cm = 72 pt = 6 picas. Switch to 300 DPI and it takes 300 pixels to fill that same inch (150 px = 0.5 in = 1.27 cm).

WHAT YOU CAN DO

- Convert between pixels, inches, cm, mm, points, picas and em

- Set any resolution, or tap a preset (72, 96, 150, 300, 326 DPI)

- Set a base font size to convert em accurately

- See your value broken down into every unit at once

- Browse a quick-reference table of common pixel sizes at your chosen DPI

- Learn the formulas and where each unit comes from with a plain-language guide

BUILT FOR CLARITY

A precise, screen-native "Pixel" design with electric cyan and magenta accents puts the converted figure first, with a full unit breakdown right beside it. Light and dark themes, a tiny download, no clutter and no account required.

WHO IT IS FOR

Designers, developers, print and DTP users, students and anyone who needs to move between screen pixels and physical measurements quickly.

AN EDUCATIONAL TOOL

Results depend entirely on the DPI/PPI you enter. For print or production work, always confirm the exact resolution of your device or output target. This app is for general information and education only and is not professional design, print or measurement advice.
