Rules used: this checker uses a 2,200-character caption ceiling and counts Unicode code points for the primary budget while also showing visible grapheme and UTF‑16 counts for edge cases, and flags more than five hashtags for current Instagram app posting. The feed preview cutoff is intentionally user-adjustable because truncation varies by surface, device and layout. Meta's publishing API can expose different hashtag constraints from the consumer app, so the tool does not treat API rules as identical to app rules. Reviewed 26 Sep 2026.
