Practical guide
Check against your own server’s limit
Mastodon is made of independent servers, and each one picks its own character limit. 500 is the default, but many servers allow more and a few allow less.
Use the limit field below to enter your server’s value; the progress bar and remaining count update immediately. Links are counted at a fixed length on Mastodon, so this page applies that when you paste URLs.

Pro tips
Pro tips for Mastodon posts
The limit depends on the server
500 characters is the default. Each Mastodon server chooses its own limit, so confirm yours before relying on the number.
Links are shortened for counting
Mastodon counts every URL as 23 characters, however long the link is. This counter applies the same rule when you paste a link.
