How Threads counts

500 characters per post

Threads stops a post at 500 characters, spaces, line breaks and emojis included.

One topic tag

Threads uses a single tag as the post's topic, so pick the one that matches the conversation you want to join.

Longer? Make it a thread

Split a long post into several connected posts instead of cutting the idea short.

Example: “Hot take: most brands post too much on Threads. Quality over volume.” = 68 characters on Threads

Limits checked on October 10, 2026, against each network's rules and the limits Mydrop's editor enforces.

Mydrop data

How long should a caption be? Past 80 characters, it barely matters.

We measured 4,848 posts on 336 accounts connected to Mydrop, over 180 days to September 2026. Each post is scored against its own account's median, so a global brand and a local shop compare fairly.

Engagement vs the account's typical post

under 80 characters702 posts−9%
80-150 characters521 posts+3%
150-300 characters914 posts±0%
300-600 characters1,632 posts±0%
600+ characters1,079 posts+1%
  • Captions under 80 characters earned 9% less engagement than the account's typical post.
  • Captions of 80 to 150 characters did best, 3% above.
  • From 150 to 600+ characters, length moved engagement by 1% or less.

Where the "more" cut lands depends on the screen and the line breaks, so treat those figures as a guide. The character limits are hard limits: the network refuses anything longer.
