# `use_cap_height_to_scale_fallback_fonts = false`

{{since('20210502-130208-bff6815d')}}

When set to true, use the *cap-height* font metrics of the base and the current
font to adjust the size of secondary fonts (such as bold or italic faces) to
visually match the size of the base font.

The default is `false`.
