Frequently asked questions
- What are the caption limits for each platform?
- Instagram: 2 200 characters. X/Twitter: 280. LinkedIn: 3 000. TikTok: 2 200. YouTube description: 5 000. These are the official limits as of 2026.
- Does the checker count emojis correctly?
- Yes — it counts Unicode grapheme clusters, so a flag emoji (two code points) counts as one character, exactly like the platforms do.
- Can I check multiple platforms at once?
- Yes — select 'All platforms' to see a dashboard of every limit at a glance.
- Does it count hashtags and mentions?
- Yes — # and @ symbols plus the text after them all count towards the character limit.
- What happens when I go over the limit?
- The counter turns red and shows how many characters you need to cut. The text isn't truncated — you decide what to trim.
- Is the caption checker free?
- Yes — free, no signup, unlimited checks.
- Does the tool save my captions?
- No — everything runs in your browser and nothing is stored.
- Can I use it on mobile?
- Yes. The tool is responsive and works in mobile Safari and Chrome.
- Do line breaks count as characters?
- Yes — a line break is one character on every platform.
- Does Twitter/X count URLs differently?
- On X, every URL counts as 23 characters regardless of length. This tool counts actual characters; for exact X counts with URLs, add 23 per link manually.
