Reddit Character LimitsReddit titles cap at 300 characters and cannot be edited after posting, which makes the title the highest-stakes field on the platform. Text posts allow 40,000 characters and comments 10,000 - long enough that the constraint is the reader's patience, not the cap.
Verified July 2026. Platforms adjust limits over time.

WordLimit shortens your text to the exact word or character count you need - it trims redundancy while keeping your key information and your own writing style, so human-written text stays recognizably human. Check your current count with the free word limit counter first.
300 characters as of 2026, and titles are permanent once posted. Some subreddits impose stricter title rules on top of the sitewide cap.
Text posts allow up to 40,000 characters and comments up to 10,000. If you are bumping into either, tightening usually serves the post better than splitting.
