Reddit character limits and image sizes
This page lists every Reddit text limit and upload size tracked by the tool, including the point where Reddit truncates a post in the feed. Counts follow how Reddit itself measures text, not raw string length.
Reddit character limits
| Field | Limit | Visible in feed |
|---|---|---|
| Post title | 300 | — |
| Text post | 40,000 | — |
| Comment | 10,000 | — |
“Visible in feed” is roughly where the platform collapses the rest behind a “more” link. It is the practical limit for anything you need read.
Limits for other networks
Limits are checked against public platform documentation and change occasionally — verify anything business-critical. Limits last reviewed .
