Strokes
Think about the strokes you make with a pen when printing
letters and you'll have an idea what the broad meaning of stroke is for a font.
Most letterforms are made up of several specific types of strokes:
Stems - In a way, it's like a flower stem.
Extenders - Reach for the sky or touch your toes.
Arms - If a letter were a person, these would be like arms.
Cross bars - Think of them as connecting strokes.
Cross Strokes - Cross your t's.
Tail - A few letters love to wag their tails.
Leg - Most letters don't have one to stand on.
Bowls - Not for soup or cereal, they hold nothing.
An upward vertical stroke
found on the part of lowercase
letters that extends above the
typeface’s x-height.
Ascender
The part of the letters that
extends below the baseline.
Descender
The invisible line marking
the height of ascenders
in a font.
Ascender Line
The invisible line marking
the lowest point of the
descenders within a font.
Descender Line
The fully closed,
rounded part of a letter.
Bowl
Vertical, full-length
stroke in upright characters.
Stem
The horizontal stroke in letters.
Also known as a bar.
Cross Bar
A horizontal stroke that
intersects the stem of
a lowercase t or f.
Cross Stroke
A descending stroke,
often decorative.

Leg
Counters
This part of a letter is what's inside the bowl.
It's white space or negative space, not a stroke at all.
There are other more specific terms for some of the
negative space that defines a letterform
Eye I spy a special counter.
Aperture This space could escape.
The open space in a
fully or partly closed area
within a letter.
Closed counter
Much like a counter,
the eye refers specifically to
the enclosed space in
a lowercase ‘e’
Eye
Serifs
Probably the most familiar characteristic of type,
serifs come in three basic shapes and fall into one of
two groups. Similar to serifs, each of these letter parts may be
understated or may form a distinctive, readily identifiable
element of a typeface:
Ears - Gee, why can't I hear you?
Spurs - Not just for cowboys.
Beaks - No birds here.

the upper-right side of the bowl of
lowercase g; also appears in the
angled or curved lowercase r.

at the top of letters in some

Beak
