About Mastodon Character Limits

Mastodon's default character limit is 500 characters per post (called a 'toot'), though individual instances can set their own limits. This gives you more space than Twitter/X for nuanced thoughts. Mastodon culture values thoughtful, conversational posts. The decentralized nature means communities have different norms, but generally, users appreciate content warnings, alt text for images, and respectful discourse. The extra characters allow for more context and nuance than Twitter-style platforms.
