Use this free online inches to rem converter tool to convert physical inches to root em units. Inches are an absolute print unit while REM is a scalable web unit. This converter helps translate print measurements to responsive web units.
To convert inches to rem, multiply by 96 to get pixels, then divide by the root font-size. The default root font-size is 16px. This creates a bridge between physical print measurements and scalable web typography.
Conversion Formula
rem = (in × 96) ÷ root font-size
For example, to convert 1 inch to rem with 16px root font-size, calculate (1 × 96) ÷ 16 = 6rem. Similarly, 0.5 inches equals 3rem because (0.5 × 96) ÷ 16 = 3.

What is IN?
Inches (in) are an absolute CSS unit representing physical inches, primarily used for print media. In web contexts, 1 inch equals 96 pixels based on the CSS specification. While rarely used for screen design, inches are essential for print stylesheets and ensuring accurate physical dimensions in printed documents.
What is REM?
REM (Root EM) is a relative CSS unit based on the root element's font size, typically 16px by default in most browsers. Unlike EM units which cascade based on parent elements, REM provides consistent sizing throughout the document. This makes REM ideal for creating scalable, accessible designs that respect user font-size preferences.
