Example
By specifying the font-size-adjust property, the browser will adjust the font size to be the same regardless of the font family ("verdana" has the aspect value 0.58)
div
{
font-size-adjust: 0.58;
}

Definition and Usage
The font-size-adjust property gives you better control of the font size when the first selected font is not available.
When a font is not available, the browser uses the second specified font. This could result in a big change for the font size. To prevent this, use the font-size-adjust property.
All fonts have an "aspect value" which is the size-difference between the lowercase letter "x" and the uppercase letter "X".
When the browser knows the "aspect value" for the first selected font, the browser can figure out what font-size to use when displaying text with the second choice font.
