|This page documents an English Wikipedia ing guideline.|
It is a generally accepted standard that ors should attempt to follow, though it is best treated with common sense, and occasional exceptions may apply. Any substantive to this page should reflect consensus. When in doubt, discuss first on the talk page.
|This page in a nutshell: Articles should be neither too big nor too small.|
This page contains an overview of the key issues concerning article size. There are three related measures of an article's size:
The article size impacts usability in multiple ways:
When an article is too large, consider breaking it into smaller articles, spinning part of it out into a new article, or merging part of it into another existing article. When an article is too small, it may be merged with one or more other existing articles. Such orial decisions require consensus. Guidelines on the size of articles, and detailed solutions, are provided below. The licensing policy mandates that whenever any content is copied from one article to another new or existing article, an summary containing the required copy attribution must be used.
Each Wikipedia article is in a process of evolution and is likely to continue growing. Other ors will add to articles when you are done with them. Wikipedia has practically unlimited storage space; however, long articles may be more difficult to read, navigate, and comprehend.
An article longer than one or two pages when printed should be divided into sections to ease navigation (see Wikipedia:Manual of Style and Wikipedia:Layout for guidance). For most long articles, division into sections is natural anyway. Readers of the mobile version of Wikipedia can be helped by ensuring that sections are not so long or so numerous as to impede navigation.
A page of about 10,000 words takes between 30 and 40 minutes to read at average speed, which is close to the attention span of most readers. Understanding of standard texts at average reading speed is around 65%. At 10,000 words it may be beneficial to move some sections to other articles and replace them with summaries per Wikipedia:Summary style – see Size guideline (rule of thumb) below.
Articles that cover particularly technical subjects should, in general, be shorter than articles on less technical subjects. While expert readers of such articles may accept complexity and length provided the article is well written, the general reader requires clarity and conciseness. There are times when a long or very long article is unavoidable, though its complexity should be minimized. Readability is a key criterion.
Readable prose is the main body of the text, excluding material such as footnotes and reference sections ("see also", "external links", bibliography, etc.), diagrams and images, tables and lists, Wikilinks and external URLs, and formatting and mark-up.
XTools shows prose information, including number of characters (under "Prose" in the "General statistics" section). It may be used for an article currently being looked at by selecting the View History tab for the page, then Page Statistics from the line near the top headed External Tools. The prosesize gadget is also helpful for estimating readable prose size.
Lists, tables, and other material that is already in summary form may not be appropriate for reducing or summarizing further by the summary style method. If there is no "natural" way to split or reduce a long list or table, it may be best to leave it intact, and a decision made to either keep it embedded in the main article or split it off into a stand-alone page. Regardless, a list or table should be kept as short as is feasible for its purpose and scope. Too much statistical data is against policy.
Wikipedia articles are in constant need of maintenance. This ranges from minor s correcting spelling and grammar, to major updates reflecting new events and new source material. Some articles may require being rewritten after some time, especially articles created about recent events. It is generally good practice to ensure that articles do not become too long to maintain, especially articles in need of frequent updating. Maintenance can become more difficult when the amount of text on a topic grows.

Total article size should be kept reasonably low, particularly for readers using slow internet connections or mobile devices or who have slow computer loading. The text on a 32 kB page takes about five seconds to load for ing on a dial-up connection, with accompanying images taking additional time, so pages significantly larger than this are difficult for older browsers to display. Some large articles exist for topics that require depth and detail, but typically articles of such size are split into two or more smaller articles.
Mobile browsers can be a problem if these devices have little memory and/or a slow CPU; long pages can take too much time to process, if they can be fully loaded at all. When using slow connections, e.g., a desktop computer with an analog modem dial-up or the wireless connection of some mobile devices, long articles can take too much time to load. For notes on unrelated problems that various web browsers have with MediaWiki sites, and for a list of alternative browsers you can download, see Wikipedia:Browser notes.
The maximum limit for Wikipedia is via the MediaWiki software's wgMaxArticleSize to 2 MiB (specifically, 2048 kibibytes or 2,097,152 bytes).
Exceeding the post-expand limit will result in templates in the article appearing incorrectly.
Very large articles should be split into logically separate articles. Long stand-alone list articles are split into subsequent pages alphabetically, numerically, or subtopically. Also consider splitting and transcluding the split parts (for example with Template:Excerpt).
When splitting a section into a new article, you should refer to the steps in WP:PROPERSPLIT, including an summary in the new article attributing the origin of the content to the existing article.
There is no need for haste in splitting an article when it starts getting large. Sometimes an article simply needs to be big to give the subject adequate coverage. If uncertain, or with high-profile articles, start a discussion on the talkpage regarding the overall topic structure. Determine whether the topic should be treated as several shorter articles and, if so, how best to organize them. If the discussion makes no progress consider adding one of the split tags in order to get feedback from other ors.
A relatively trivial topic may be appropriate in the context of the larger article, but inappropriate as the topic of an entire article in itself. In most cases, it is a violation of the neutral point of view to specifically break out a controversial section without leaving an adequate summary. It also violates the neutral point of view policy to create a new article specifically to contain information that consensus has rejected from the main article. Consider other organizational principles for splitting the article, and be sure that both the title and content of the broken-out article reflect a neutral point of view.
If a section of an article is a magnet for unhelpful contributions (such as the "external links" section or trivia sections), be aware that while moving it to another article may help to clean up the main article, it creates a new article that consists entirely of a section for unwanted contributions. If an article includes large amounts of material not suitable for inclusion in the encyclopedia, it is better to remove that content than to create a new article for it.
Some useful rules of thumb for splitting articles, and combining small pages:
|Readable prose sizea||What to do|
|> 15,000 words||> 100 kB||Almost certainly should be divided|
|> 9,000 words||> 60 kB||Probably should be divided, although the scope of a topic can sometimes justify the added reading material.|
|> 8,000 words||> 50 kB||May need to be divided; likelihood goes up with size.|
|< 6,000 words||< 40 kB||Length alone does not justify division.|
|< 150 words||< 1 kB||If an article or list has remained this size for over a couple of months, consider combining it with a related page. Alternatively, the article could be expanded; see Wikipedia:Stub.|
|a Each kB can be equated to 1,000 characters|
Please note: These rules of thumb apply only to readable prose and not to wiki markup size (as found on history lists or other means). Word counts can be found with the help of Shubinator's DYK tool or Prosesize.
The rules of thumb apply somewhat less to disambiguation pages and naturally do not apply to redirects. Readable prose tools do not count words or characters in image captions, lists or tables. When considering to split list articles, consider the impact of breaking up a sortable table.
Removing appropriate content, especially summary style, and/or reliably sourced and non-tangential information, from an article simply to reduce length without moving that content to an appropriate article either by merging or splitting, may require a consensus discussion on the talkpage; see Wikipedia:Content removal#Reasons for acceptable reasons.
Markup or markup language is the code used to organise a document and make it readable. Wiki markup is the codes used on Wikipedia. Markup size includes readable prose, the wiki codes, and any media used in the article, such as images or audio clips. Markup size will always be greater than or equal to the readable prose size on which the above size guideline is based.
You can find the size of the markup of a page in bytes from its page history (near the bottom). Also the search box entry:
intitle:Article title will show both number of words in the article and the size of the article in kilobytes. In most cases these are not reliable indications on their own of whether an article should be split.
The largest articles by markup size are listed at Special:Longpages.
Note that the ability to a section rather than the entire page decreases wait time, removing some of the many, oversized-page problems for ors; however, readers with slow connections will still have to wait for the entire page to load.
If you have encountered an article that is so long you can't it, or if your browser chops off the end of the article when you try to it, there are a few ways you can solve the problem.
The best improvement is to simply upgrade to a more modern web browser, if possible. There are also many other benefits to upgrading to their latest version, such as better security, better displaying of content written to more modern HTML, and bug fixes. Many articles on Wikipedia may be longer than 32 kB on a permanent basis, so older browsers will continue to have occasional problems with long articles.
Often you can the article one section at a time by using the "Edit" links you see next to each header in the article. This should work as long as none of the sections are longer than 32 kB, which they really shouldn't be. You can text before the first section by ing the first section, then changing the
§ion=1 part of the URL to
If you find a section too long to correctly and safely, or have a problem otherwise relevant, you can post a request for assistance on the help desk. Follow the "New section" link, which will allow you to post a new comment without ing any existing text.
