Screen Resolution Guide

It takes Width and Height and derives Total pixels, Megapixels and Aspect ratio from them. The calculation is live as you type, so the result updates on every change.

2 values: Width (px) and Height (px). Nothing else is required — no account, no file upload.

With Width = 1,920 px and Height = 1,080 px, the calculator returns Total pixels = 2,073,600, Megapixels = 2.074 MP and Aspect ratio = 16:9. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

It moves a lot. Using Width = 3,840 px and Height = 2,160 px instead, Total pixels goes from 2,073,600 to 8,294,400 — which is why it is worth testing a few scenarios rather than trusting a single figure.

Enter Width px and Height px. Metric and US units are both supported — switch system and the figures convert for you.

Scaled down to Width = 960 px and Height = 540 px, Total pixels comes out at 518,400. The relationship is worth checking at both ends before you rely on a single result.

Verifying a download matches its published checksum, comparing two files without reading them, and generating a signature for an API request.

Hashing a password with a fast algorithm. MD5 and SHA are built to be quick, which is exactly wrong for passwords — those need a deliberately slow function like bcrypt, scrypt or Argon2.

This one returns Total pixels and Megapixels; the Screen size calculator returns Width (cm) and Height (cm). That is the whole difference — open the one whose figure you need.

The digests follow their published specifications and are computed by the browser's own crypto implementation where one exists, so a value can be checked against any other conforming tool.
