Wikipedia Translation

How many languages are currently available on Wikipedia?

As of 2025, Wikipedia operates in over 330 language editions. Each language edition is a separate encyclopedia with its own articles, editorial community, and policies. They share a common technical platform and some overarching Wikimedia Foundation guidelines, but operate largely independently of one another.

The size of each language edition varies enormously. The English Wikipedia is by far the largest, with over 6.7 million articles. Many smaller language editions have only a few thousand articles, often created or expanded through automated bots rather than human editors.

Not all language editions are equally active or well-maintained. The quality and depth of coverage in smaller language editions can vary significantly, and editorial standards, while based on the same core principles, may be applied differently than in the English Wikipedia.

Which Wikipedia languages are the most popular?

By article count, the largest Wikipedia language editions are English, Cebuano, Swedish, German, French, Dutch, Russian, Italian, Spanish, and Polish. However, article count is a somewhat misleading metric. The Cebuano and Swedish editions have large article counts largely due to bot-generated stub articles, not active human editorial communities.

By readership and editorial activity, the most significant Wikipedia language editions are:

• English: By far the most visited and most influential for AI training and search visibility.
• German: One of the most rigorously maintained editions, with strict editorial standards.
• French: Large, active editorial community with broad international readership.
• Spanish: Significant reach across Latin America and Spain.
• Japanese, Chinese, Arabic, Portuguese: Major language editions with large readerships in their respective regions.

For most brands and individuals, the English Wikipedia page is the most impactful for AI visibility and search rankings. Translation into other languages is most valuable when you have a genuine presence or audience in those markets.

Do different language Wikipedias have different guidelines and policies?

Yes, and this is an important practical consideration for anyone pursuing multi-language Wikipedia coverage.

All Wikipedia language editions share the same core content principles (neutral point of view, verifiability, no original research) because these are Wikimedia Foundation policies that apply across the entire project. However, each language edition operates its own editorial community and can develop its own supplementary guidelines, notability standards, and practices.

In practical terms, this means:

• A subject that meets notability requirements on the English Wikipedia may not automatically meet the standards of another edition. The German Wikipedia, for example, has a reputation for particularly strict notability enforcement.
• Citation requirements and acceptable sources vary by edition. A source that is considered reliable on English Wikipedia may not be recognized by another edition's editorial community.
• The AfC review process and submission workflows differ between editions. Some editions have faster review processes; others have significant backlogs.
• Translated articles cannot simply be copied from one edition to another. Each edition's article must meet that edition's standards independently.

Working with an editor who has experience across multiple language editions, rather than just the English Wikipedia, is important for multi-language projects.

Who translates pages for Wikipedia?

Wikipedia translations are carried out by volunteer editors who are fluent in both languages and familiar with the editorial standards of the target language edition. There is no centralized translation department. Like all Wikipedia content, translation is a volunteer-driven activity.

Wikipedia does provide a Content Translation tool that assists editors in translating articles between editions, but the tool produces a starting point that requires human review, editing, and adaptation to the target edition's standards. Machine translation alone, whether from Wikipedia's tool, Google Translate, or AI, is not acceptable as a final Wikipedia article without substantial human editing.

When hiring a professional service for Wikipedia translation, the editor working on the project needs to be:

• Fluent in both the source and target languages
• Familiar with the editorial conventions of the target language edition
• Able to identify and replace sources that are not recognized as reliable in the target edition
• Aware of the notability standards specific to the target edition

Translation projects require more than linguistic skill. An editor who is fluent in Spanish but unfamiliar with the Spanish Wikipedia's editorial community and standards will produce an article that may be flagged or deleted regardless of translation quality.

How much does it cost to translate a Wikipedia article to another language?

The cost of translating a Wikipedia article depends on the language, the length and complexity of the article, and the level of editorial work required beyond translation itself.

A straightforward translation of an existing English Wikipedia article into a major language edition (Spanish, French, German, Portuguese) typically costs less than creating a new article from scratch, because the source content and structure already exist. The work involves translation, adaptation to the target edition's standards, source verification, and submission.

Costs generally range as follows:

• Major language editions (Spanish, French, German, Portuguese): Typically $500 to $1,500 depending on article length and complexity.
• Less common languages: Costs can be higher due to the more limited pool of qualified editors fluent in both the language and Wikipedia's standards for that edition.
• Multi-language packages: Translating an article into several languages at once is generally more cost-efficient than commissioning each translation separately.

As with all Wikipedia services, cost should never be the primary deciding factor. An article that is poorly translated or fails to meet the target edition's standards will not survive the review process regardless of what was paid to produce it.
