Threads counter (500 + 10,000)
A regular Threads post is short. Longer writing can go in the text attachment. This page meters both so you do not mix the caps.
How to use the Threads counter (500 + 10,000)
What does the Threads counter (500 + 10,000) do?
Count an Instagram Threads draft against the 500-character post limit and the 10,000-character long-form attachment; It applies this page-specific rule: instagram’s Threads treats a standard post as a short update (500 characters in current public docs and client behavior).
Which inputs does this counter use?
To count an instagram threads draft against the 500-character post limit and the 10,000-character long-form attachment, enter Draft; keep every value in the same example; the page then updates the result from the current values; Start with a familiar case covered by this rule - Counts here use grapheme segments when Intl.Segmenter exists, so one emoji is one unit - so the expected result can confirm the settings.
How should the counter result be read?
For a result intended to count an instagram threads draft against the 500-character post limit and the 10,000-character long-form attachment, counts here use grapheme segments when Intl.Segmenter exists, so one emoji is one unit; read draft together with the original draft rather than as an isolated answer, and confirm that its units or structure match the intended use.

Limits and accuracy
When using this counter to count an instagram threads draft against the 500-character post limit and the 10,000-character long-form attachment, this is not a posting tool and it does not log in to Meta; check the result in its intended destination before relying on it for important work; keep draft until the output has been checked in its intended destination.
How this works
Instagram’s Threads treats a standard post as a short update (500 characters in current public docs and client behavior). A longer piece can ride as an attached text block with a much higher cap - widely documented as 10,000 characters.
Counts here use grapheme segments when Intl.Segmenter exists, so one emoji is one unit. If a client still uses UTF-16 code units, a rare emoji pair may differ by one. Stay a couple of characters under the line for safety.
This is not a posting tool and it does not log in to Meta. Paste, count, copy back to the app.
