Titles Decide Everything on Reddit
You get 300 characters for a title, and it is the only thing most redditors ever read. Specific beats clever: “I tested 5 free word counters for a week — here's what broke” outperforms “Word counter review”. Many subreddits also enforce their own title rules, so check the sidebar before posting.
Posting Tips
- Front-load the title. Long titles get truncated in feeds and search — the first ~100 characters should stand alone.
- Long text posts work on Reddit — unlike other platforms, detailed 1,000+ word posts routinely top subreddits. Structure them with paragraphs and headers.
- Split monster comments. If you hit the 10,000-character comment limit, a reply-to-yourself thread reads better than a cramped edit.
- Check subreddit rules — some require minimum lengths for discussion posts, others cap them.
Why won't Reddit let me submit my post?
Usually the title is over 300 characters or the body exceeded 40,000. Paste it here first — the character stat tells you exactly how much to trim.
Do individual subreddits set their own rules?
Yes. Reddit's platform limits are the ceiling, but most large subreddits add stricter rules — minimum word counts, title formats, flair requirements — enforced by AutoModerator. Check the sidebar before you write, not after a removal.
