In typing, how much space is recommended before a hyphen?

In typing, it is recommended to use 0 spaces before a hyphen. The hyphen is used to connect words or parts of words, such as in compound adjectives (e.g., well-known) or when breaking a word at the end of a line. Placing spaces before a hyphen would create confusion, as it disrupts the visual flow and could lead to misunderstandings about the relationship between the words it's connecting.

Using 1 space, 2 spaces, or always providing 3 spaces before a hyphen is unnecessary and goes against standard typing conventions. Proper formatting and adherence to these conventions contribute to clarity in written communication.
