REM to PT Converter
Conversion Guide
1. Convert rem to px (multiply by root font size, typically 16px). 2. Convert px to pt. Example: 1rem = 16px = 12pt

Frequently Asked Questions
Basics
What is REM?
The rem (root em) unit is a relative unit that's always based on the font-size of the root element (html). This makes it powerful for creating consistent, scalable layouts that respect user preferences. Unlike em units which compound in nested elements, rem always refers back to the root font-size.
Why should I use rem instead of pixels?
REM units provide better accessibility by respecting user font size preferences, maintain consistent scaling across the site, and simplify responsive design. Unlike pixels, rem units scale proportionally when users change their browser's font size settings.
How do I calculate rem values from pixels?
To convert pixels to rem, divide the desired pixel value by the root font size (typically 16px). For example: 32px ÷ 16px = 2rem. Many code editors and dev tools can do this calculation automatically.
What's the difference between rem and em units?
While both are relative units, em is relative to the font-size of the current element or its closest parent with a defined font-size. rem is always relative to the root element, making it more predictable for layout and preventing compound scaling issues.
When should I use rem vs em units?
Use rem for consistent spacing, layout and general typography. Use em when you want elements to scale relative to their parent's font size, like padding in buttons or line-height in paragraphs.
How can I debug rem calculations?
Most browser dev tools can show both rem and pixel values. You can also set a more convenient root font-size (like 10px) to make calculations easier: html { font-size: 62.5%; } (making 1rem = 10px)
What is PT?
Points (pt) are absolute-length units primarily used in print. One point is equal to 1/72 of an inch.
Should I use pt for web content?
Points are generally not recommended for web content. Use relative units like rem or em for better accessibility and responsiveness.
When are points useful?
Points are mainly useful in print stylesheets (CSS @media print) where precise physical measurements are needed.
