Similarly, you may ask, what is the space between lines of text called?
The vertical space between lines of type is called leading (rhymes with sledding). Leading is measured from the baseline of one line of text to the baseline of the line above it. Baseline is the invisible line on which most letters sit.
Secondly, what are the parts of letters that fall below the baseline called? A descender is the part of a character that descends below the baseline. Typically, you will see descenders on the letters g, j, q, p, y, and sometimes f.
Likewise, what is the term for measurement in letterforms?
Point Sizes. The point is used to measure the size of a font. One point is equal to 1/72 of an inch. When a character is referred to as 12pt, the full height of the text block (such as a block of movable type), and not just the character itself, is being described.
What is used to change the spacing between all characters in a block of text?
Kerning and Leading are ways to manipulate the spacing between characters.
