Bluesky Character Counter

Q: What is the Bluesky post limit?

Each post can contain 300 graphemes. The limit is measured in graphemes, not bytes or individual characters.

Q: How does Bluesky count skin-tone emoji?

An emoji with a skin-tone modifier, such as 👍🏽, counts as one grapheme.

Q: Do replies and threads share one limit?

No. Each reply and each post in a thread has its own 300-grapheme limit.

Q: What media can I add to a Bluesky post?

A post can have up to 4 images or 1 video. Each image has a hard limit of 1,000,000 bytes, about 0.95 MiB; uploading right at that boundary can cause server rejection. Videos can be up to 3 minutes and 100 MB.

Bluesky allows 300 graphemes per post. Paste your text to count graphemes, including emoji with skin-tone modifiers, before scheduling it.
