How this social media character counter works

Paste your caption, pick a platform, and see a live count against the official limit used by Postmixr when you schedule posts. The counter uses grapheme segmentation (via Intl.Segmenter) so emojis and combined characters are measured closer to how Instagram, TikTok, and other apps enforce limits, not just raw JavaScript string length.

Nothing leaves your browser. There is no login, no upload, and no AI. Use it while drafting in Notes, Google Docs, or your scheduler, then copy the final caption into Postmixr or any tool you prefer.

Instagram character limit

Instagram captions allow up to 2,200 characters. That total includes your hook, body copy, hashtags, mentions, and line breaks. If you are optimizing for the Instagram character limit, aim to front-load the first line, it is what people see before “more”, and keep hashtag blocks easy to trim if you go over.

Many creators target 150–300 characters for feed posts and save longer storytelling for carousels or Reels descriptions. This counter updates instantly so you can shave lines without guessing.

TikTok caption limit

TikTok captions also cap at 2,200 characters, but short, searchable copy usually performs better. The TikTok caption limit is generous; the constraint is attention, not the number. Count characters here before you paste into TikTok or schedule a video with Postmixr.

Threads, YouTube, Facebook, and Pinterest limits

Threads posts are limited to 500 characters, ideal for punchy takes and thread openers. YouTube video descriptions allow up to 5,000 characters (use the first two lines for search and clicks). Facebook Page posts support very long text, but readability drops after a few hundred characters. Pinterest pin descriptions work best under 500 characters with a clear keyword and CTA.

  • Switch the platform dropdown to jump between limits without re-pasting.
  • Watch the progress bar: yellow when you are within 50 characters of the cap, red when over.
  • Schedule the same caption to multiple networks from one calendar in Postmixr after you are under every limit.

FAQ

What is the Instagram character limit in 2026?

Instagram captions allow up to 2,200 characters, including hashtags, mentions, and line breaks. The first line is truncated in the feed, so put your hook upfront.

Does Instagram count emojis as one character?

Some emojis count as two characters on Instagram and other apps. This tool uses grapheme segmentation (Intl.Segmenter) to approximate platform behavior more accurately than a basic character count.

What is the TikTok caption character limit?

TikTok allows up to 2,200 characters per caption, the same ceiling as Instagram. Short, keyword-rich copy usually performs better than maxing out the limit.

How many characters can a Threads post be?

Threads limits posts to 500 characters. Use this counter with Threads selected when drafting thread openers or single posts.

Do I need an account to use this character counter?

No. Everything runs locally in your browser. Your caption is never uploaded or stored on our servers.
