PX to REM Converter
Convert pixels to rem (and back) for scalable typography.
Building with rem units keeps your typography scalable and respectful of user font-size settings. Enter a pixel value and a base font size (16px by default) to get the exact rem equivalent — and vice-versa.
Why rem matters
- Layouts in rem scale cleanly when users change their browser font size.
- It improves accessibility and is a small but real SEO/UX win.
- Set your project’s root font size once and convert every measurement against it.
