Edit distance matrix for two words using cost of substitution as 1 and cost of deletion or insertion as 0.5. For example, the Levenshtein distance between "kitten" and "sitting" is 3, since the following 3 edits change one into the other, and there is no way to do it with fewer than 3 edits: kitten → sitten (substitution of "s" for "k"),
Letter spacing, character spacing or tracking is an optically consistent typographical adjustment to the space between letters to change the visual density of a line or block of text. Letter spacing is distinct from kerning , which adjusts the spacing of particular pairs of adjacent characters such as "7."
The most widely known string metric is a rudimentary one called the Levenshtein distance (also known as edit distance). [2] It operates between two input strings, returning a number equivalent to the number of substitutions and deletions needed in order to transform one input string into another.
Typography is the art and technique of setting written subject matter in type using a combination of typeface styles, point sizes, line lengths, line leading, character spacing, and word spacing to produce typeset artwork in physical or digital form. The same block of text set with line-height 1.5 is easier to read: Typography is the art and technique of setting written subject matter in type ...
These letters can be added to the class of the base letter, and can stay together whether they are the first or second character in a pair: (a à á â), (e è é ê), etc. A letter cannot be included in the class if its kerning is different from the others in certain pairs (for example, Yá vs. Yä).
A generalization of the edit distance between strings is the language edit distance between a string and a language, usually a formal language. Instead of considering the edit distance between one string and another, the language edit distance is the minimum edit distance that can be attained between a fixed string and any string taken from a ...

In typography, the x-height, or corpus size, is the distance between the baseline and the mean line of lowercase letters in a typeface.Typically, this is the height of the letter x in the font (the source of the term), as well as the letters v, w, and z.
