This page in a nutshell: Splitting is the procedure by which the contents of a page are split into several pages. The two reasons for splitting are page size and content relevance. For uncontroversial splits, no permission is needed to split; just do it. If unsure, use one of the tags/templates below, and start a discussion on the talkpage. Use a good edit summary to comply with the license requirements.

If an article becomes too large, or a section of an article has a length that is out of proportion to the rest of the article, it may be appropriate for some or all of the article to be split into new articles. In some cases, refactoring an article into child or sister articles can allow subtopics to be discussed more fully elsewhere without dominating a general overview article to which they are non-central (but only if the new articles are themselves sufficiently notable to be included in the encyclopedia).
