Examples of ascenders are uppercase letters and some lower case letters. The lower case letters that are ascenders are: 'b, d, f, h, i, j, k, l, t'. The opposite of an ascender is a descender that has a portion of the letter going below the baseline which is the lowest blue line on the above image.

What is an ascender in type?

In typography and handwriting, an ascender is the portion of a minuscule letter in a Latin-derived alphabet that extends above the mean line of a font. That is, the part of a lower-case letter that is taller than the font's x-height. Ascenders, together with descenders, increase the recognizability of words.

What type of letters have ascenders and descender?

(See the next post in 2 days time if you're not sure what the x-height is.) Letters with ascenders are usually: b, d, f, h, k, l, t. Letters with descenders are usually: g, j, p, q, y. Lowercase f and z also have descenders in many typefaces.
