What font is x-height?
X-height refers to the height of the lowercase x for a typeface, and it indicates how tall or short each glyph in a typeface will be. Typefaces with tall x-heights have better legibility at small font sizes, as the white space within each letter is more legible.
What x-height ratio is better for legibility?
The most efficient typefaces with the best ratio of x-height and cap height seem to be Wayfinding Sans Pro and Johnston Underground with an x-height between 67 to 69 percent of the cap height. Using typefaces with a significantly higher x-height will probably not increase the legibility any further.
How do you show x-height?
The x-height refers to the distance between the baseline and the top of the lower case line in a typeface. Typically, this is the height of the letter x in the font (the source of the term). The x-height is a relative measure of typeface, so different typefaces set in the same point size may appear differently.
How to calculate the size of a font?
It can be identified by measuring the x-height of a known font size to determine the ratio between the x-height M and font size S: If no individually determined value is entered in the prescribed field, the Font Size Calculator assumes an x-height-font size ratio of 0.47 as standard.
Which is the correct golden ratio for font size?
For a font size of 16px, the perfect line height is achieved when h equals the golden ratio. This yields a value of 25.88854px for the optimal line height. Using this value, you can then determine that the associated optimal line width is 670.21670px.
What is the x height of a typeface?
In typography, the x-height, or corpus size, is the distance between the baseline and the mean line of lower-case letters in a typeface.
How big of a font do you need for lowercase letters?
Taking our previous example, which uses 3/8 of an inch as the minimum height requirement of the font, you will still have to go to a larger font size than 27 pt, if you are using lowercase letters.
