Tips for this platform
Title: 300 characters
Reddit title limit is 300 characters, but most subreddits prefer concise, descriptive titles.
Body: 40,000 characters
Self-post body limit is 40,000 characters. That's roughly 6,000–8,000 words.
Comment: 10,000
Comments cap at 10,000 characters — enough for a detailed reply, not a mini essay.
Subreddit rules override
Each subreddit can set its own minimums (e.g., r/AskHistorians requires in-depth answers).

What works on Reddit
- Follow the subreddit's rules — moderators remove off-topic or low-effort posts
- Use Markdown for formatting — headers, lists, code blocks, quotes
- Title is the hook — most of upvoting happens from the feed, not the post page
- Stay topic-first; self-promo without participation gets downvoted
