HTMLFontElement: size property

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The obsolete HTMLFontElement.size property is a string that reflects the size HTML attribute. It contains either a font size ranging from 1 to 7 or a number relative to the default value 3, for example -2 or +1.

The format of the string must follow one of the following HTML microsyntaxes:

Microsyntax Description Examples
Valid size number string integer number in the range of 1-7 6
Relative size string +x or -x, where x is a number relative to 3 (the result should be in the range of 1-7) +2


A string.


// Assumes there is <font id="f"> element in the HTML

const f = document.getElementById("f");
f.size = "6";


The <font> element has been deprecated and is no longer supported and, as a result, neither is <font>.size.
