Social Media Character Counter

It depends on the platform. Most apps, including Instagram, Bluesky and Threads, count what you see, so one emoji is one character. X counts every emoji as two characters. This tool counts user-visible characters for most platforms and applies X's own weighting for X.

X gives every link a fixed weight of 23 characters, whatever its real length, because it shortens links with t.co. It also counts emoji and characters such as Chinese, Japanese and Korean as two. The X row in this tool uses the same rules, so it should match what X shows.

Instagram captions can be up to 2,200 characters with a maximum of 30 hashtags. Only about the first 125 characters show in the feed before the caption is cut off with 'more', so put your hook and call to action at the start.

One SMS can carry 160 characters from the standard GSM alphabet. Longer messages are split into segments of 153 characters, because each part needs a small header. If your message contains any emoji or character outside the GSM alphabet, the whole message switches to Unicode, and the limits drop to 70 and 67 characters. Carriers bill per segment.

The limits were checked against each platform's published defaults in October 2026. Paid plans can raise some of them, for example X Premium and Discord Nitro, and platforms change limits from time to time, so check the app if you are right at the edge.
