Frequently asked questions
How many characters can a Bluesky post have?+
300 characters. This counter uses the same per-character counting most networks use, where an emoji counts as one character.
Do emojis count as one character?+
Most networks count one visible emoji as one character, although a few complex emoji (skin tones, flags) can count as two. This tool counts visible characters and shows the emoji count separately.
Do links count towards the limit?+
On Bluesky links count at their full length. Use a short link or the UTM builder to keep them tidy.
Does this tool store my text?+
No. Everything runs in your browser; nothing is sent to a server.
