Letter-spacing is not the same as kerning, which alters the spacing of certain pairs of adjacent letters, such as "7," which would seem badly spaced if left alone. Letter spacing affects the overall size of a text string. Kerning involves adjusting the distance between two specific items in a document - usually two characters or glyphs that are to be rendered in close proximity to one another. There are several ways to adjust the spacing between characters without affecting their appearance: the user can change the device's font size, thereby changing the space between all words of a given size; or they can choose a different typeface with varying amounts of space between letters.
Kerning is the spacing between letters that varies by character to make aesthetically pleasing typography. It allows designers to adjust the distance between characters without affecting the reading order of the text.
There are three types of kerning: horizontal, vertical, and diagonal. Horizontal kerning refers to the adjustment of the spacing between two adjacent words on the page. Vertical kerning involves adjusting the distance between two sentences of the same paragraph. Diagonal kerning refers to the adjustment of the spacing between two non-adjacent letters on the page. For example, if there is too much space between "a" and "b" in a word, you could kern them to reduce the gap.
Horizontal kerning is done manually by designers before they start typing away their text document. They will go through each word and decide how much space should separate them. This is called "wordspacing".
Vertical kerning is done with the alignment tools in most word processors. They allow you to choose between several different options for justifying your text. The default option is "tight", which means that all lines of text will have the same amount of space above and below them.
When letters are not correctly spaced, the appearance of your design suffers. The worst kerning is frequently the result of not kerning at all, relying on the typographer and your graphic design tools to perform their jobs correctly. You get fortunate a lot of the time, but there's no need to leave the success of your design to chance. There are many ways you can ensure that your typeface looks its best by using proper kerning.
Kerning refers to the process of adjusting the spacing between characters in a word or text string. Properly used, it allows you to create designs that are both attractive and readable. When done incorrectly, however, it can make reading difficult by causing words to overlap or giving an otherwise pleasing composition a messy look.
In order for kerning to be effective, certain conditions must be met. First, the typefaces must be equally spaced (i.e., they should have the same leading). If they don't, then some sort of adjustment needs to be made so that they do. For example, if one typeface has more space between each letter than another, then those letters should be adjusted down so that they appear equal in height.
Secondly, the amount by which each typeface is kerned must be consistent across the entire design. If some letters are spaced much closer together than others, the effect will not be uniform and your design will not read properly.
