Reddit Character Counter — Title & Post Limit Checker

Reddit character limits

Reddit caps a post title at 300 characters and a self-post body at 40,000 characters. Comments also allow up to 10,000 characters. The title is the part that has to earn the click in busy feeds, so the 300-character limit is the one most worth watching. This tool counts your title and body live so neither gets rejected when you hit submit.

Titles do the heavy lifting

On Reddit, the title carries the post — many subreddits are link-and-title only, and even text posts are judged on the title first. You have 300 characters, but the strongest titles are far shorter and specific. Lead with the concrete detail or question that makes someone curious, and check each subreddit’s rules, since many add their own title format or tag requirements.

Bodies, comments, and flair

Self-post bodies can run to 40,000 characters — plenty for detailed write-ups, guides, and AMAs, with Markdown for formatting. Comments cap at 10,000 characters, and user flair is far shorter at around 64. Links, Markdown syntax, and emoji all count toward these limits, so the live counter reflects exactly what Reddit will accept before you post.

Private and instant

Paste a draft title and body to see character counts and remaining space at a glance. Everything runs in your browser, so nothing you type is uploaded — handy for drafting longer posts or AMAs before they go live. Trim the title until it’s within 300 characters, then post with confidence.
