Common Character Limits and Best Practices

Here are some character limits or recommendations you may encounter on the Internet:

Social Media

Twitter/X Post: 280 characters
Source: docs.x.com X Premium users can post up to 25,000 characters.
Facebook Post: 63,206 characters
"When Mashable asked, Lavrusik explained what that meant, exactly: You can now post a status update measuring 63,206 characters." Source: mashable.com Shorter is probably better. Buzzsumo recommends Facebook posts shorter than 50 characters; Kurt Gessler suggests there's "no one-size-fits-all approach."
Instagram Caption: 2,200 characters (unconfirmed)
Widely reported as 2,200 characters, but Instagram apparently doesn't publish official limits. Captions are truncated with a "...more" link, though the exact truncation point may vary by device and context.
LinkedIn Post: 3,000 characters
Source: www.linkedin.com/help You can publish longer articles, with a cover image or video, using LinkedIn's articles feature.
Bluesky Post: 300 characters
Source: docs.bsky.app
Mastodon Status Update: 500 characters (default)
Source: docs.joinmastodon.org
500 is the default, but Mastodon instances can be configured with any character limit.

Email & Marketing

Email Subject Line: 60 characters / 9 words (recommended)
Source: Mailchimp
Email Preview Text: 30-100 characters (recommended)
"With desktop and webmail clients, you can get away with longer preheader text (around 50-100 characters). However, for those that read your emails on mobile, many devices display an average of only 35-50 characters, so it's better to keep it short and sweet." Source: Email on Acid. The same article includes a table of how many characters of preview text appear in different email clients; iOS Gmail showed an average of 30 characters; Gmail on the web showed an average of 119. Consider your audience when choosing a length and remember that readers' use of AI may result in something else entirely being displayed.

"Any longer and Google may truncate it." Source: Claire Taylor, SearchEngineLand

Other Platforms

YouTube Description: 5,000 characters
Source: support.google.com Also: "Be sure that each video has a unique description; this makes it easier to find through search, and helps it stand out from similar videos.""
TikTok Caption: 4,000 characters
