Frequently Asked Questions

Common questions about Reddit character limits.

Reddit post titles are limited to 300 characters. Titles cannot be edited after a post is published, making this the highest-stakes field on the platform — get it right before you post.
Reddit text (self-post) bodies allow up to 40,000 characters for standard accounts. This limit was raised to 80,000 characters for Reddit Premium subscribers in a November 2025 update.
Reddit comments are limited to 10,000 characters — long enough for detailed responses and discussion threads without practical constraint for almost any reply.
Reddit usernames are limited to 20 characters. Usernames are permanent and cannot be changed after account creation, so choose carefully.
Yes. While Reddit's platform-wide limits are 300 characters for titles and 40,000 for self-posts, individual subreddit moderators can impose stricter title length, formatting, or content rules on top of the site-wide maximum. Always check subreddit rules before posting.
