An em space is a typographical space measuring one em in width.

Traditionally, for a font that uses the Latin alphabet, an em space is approximately the width of a capital letter M.

In modern digital typography, which attempts to standardize measurements for multiple languages and alphabets, an em space is usually smaller than a capital M.


In HTML (hypertext markup language), to insert an em space, use the HTML entity  .

The size of a displayed em space may vary slightly according to the browser or device that renders the text.
