Count characters, words, and sentences for your Reddit posts. Stay within Reddit limits for titles, post bodies, comments, flairs, and usernames.
The best Reddit posts hit a sweet spot in length. Too short and you provide no value. Too long and nobody reads it. Here is what the data says.
Titles between 60 and 120 characters get the highest upvote ratios on Reddit. Shorter titles lack context, while longer ones get truncated in feeds and lose clicks.
The highest-performing Reddit text posts land between 500 and 2,000 characters. This gives enough room to tell a story, share a lesson, or ask a detailed question without losing the reader.
Top-voted comments are concise but valuable. Comments between 100 and 500 characters are easy to scan and tend to receive 2 to 3x more upvotes than walls of text.
Put the most important information in the first 100 characters. Reddit users scroll fast. If your opening line does not hook them, the rest of your post will not matter.
If your post exceeds 1,000 characters, use paragraph breaks, bullet points, or headers. Nobody reads a 3,000 character wall of text. White space is your friend on Reddit.
Some subreddits favor short, punchy posts. Others reward detailed, long-form content. Check the top posts in your target subreddit to see what length performs best before posting.

Reddit post titles have a strict limit of 300 characters. This includes spaces, punctuation, and special characters. Once you hit 300 characters, Reddit will not let you submit the post. The ideal title length for engagement is between 60 and 120 characters.
Reddit text posts (self posts) have a maximum body limit of 40,000 characters. This is a generous limit that allows for detailed, long-form content. Most high-performing posts use between 500 and 2,000 characters to keep readers engaged without overwhelming them.
Reddit comments have a character limit of 10,000 characters. This gives you plenty of room for detailed responses. However, comments between 100 and 500 characters tend to get the most upvotes because they are easy to read and provide value without being a wall of text.
Yes, Reddit counts spaces as characters in both titles and post bodies. When checking your content against Reddit limits, always count the total characters including spaces. This tool shows you both counts so you can track exactly where you stand.
For titles, aim for 60 to 120 characters. For post bodies, the sweet spot is 500 to 2,000 characters depending on the subreddit. Comments that get the most upvotes are typically 100 to 500 characters. Longer content works well in discussion-heavy subreddits like r/AskReddit or r/explainlikeimfive, while shorter posts perform better in meme or news subreddits.
