size-adjust: 90%; 

size-adjust

The size-adjust CSS descriptor defines a multiplier for glyph outlines and metrics associated with this font. This makes it easier to harmonize the designs of various fonts when rendered at the same font size.

The size-adjust descriptor behaves in a similar fashion to the font-size-adjust property. It calculates an adjustment per font by matching ex heights.

Syntax

size-adjust: 90%; 

Values

A <percentage> value with an initial value of 100%.

All metrics associated with this font are scaled by the given percentage. This includes glyph advances, baseline tables, and overrides provided by @font-face descriptors.

Formal definition

Formal syntax

<percentage>

Examples

Overriding metrics of a fallback font

The size-adjust property can help when overriding the metrics of a fallback font to better match those of a primary web font.

@font-face {   font-family: web-font;   src: url("https://example.com/font.woff"); }  @font-face {   font-family: local-font;   src: local(Local Font);   size-adjust: 90%; }
