Bluesky character counter
The Bluesky limit is 300 characters per post. Paste your text to get the exact count, plus whether it fits on every other platform.
How Bluesky counts characters
Bluesky counts what you see. Every emoji counts as one character, even one built from several symbols.
Bluesky has the shortest limit of the major networks, so a caption written for Instagram usually needs its own shorter version.
