Character Limit Checker — Complete Guide & Instructions
MakeCard Character Limit Checker counts your text once and judges it against nine real platform limits at the same time — X/Twitter’s 280, Instagram’s 150-character bio, YouTube titles, LinkedIn posts, SMS and more. Each platform gets a live progress bar that turns amber near the limit and red the moment you cross it, with a running “left” or “over” count so you trim exactly enough.
How to Use Character Limit Checker
- 1 Type or paste your post, bio, title or caption into the text area.
- 2 Watch the character count at the top-right update live.
- 3 Scan each platform bar — green is safe, amber is near the cap, red is over.
- 4 Read “N left” or “N over” beside each platform name to see the margin.
- 5 Trim the text until every platform you care about shows green.
Key Features & Capabilities
- Nine real limits: X/Twitter 280, IG bio 150, IG caption 2200, YouTube title 100, YouTube description 5000, Facebook 63206, LinkedIn 3000, WhatsApp 65536, SMS 160.
- Live character count as you type.
- Per-platform progress bars — green, amber at 90%, red when over.
- Exact characters-left or characters-over readout per platform.
- One textarea, all limits — no per-platform tab switching.
- Instant for any length of text.

Practical Everyday Use Cases
- Trimming a tweet to fit 280 characters before posting.
- Writing an Instagram bio inside the strict 150-character cap.
- Checking a YouTube title stays under 100 characters so it does not truncate in search.
- Making sure an SMS stays under 160 characters to avoid multi-part charges.
- Cross-posting one caption to several platforms and seeing which limits bind.
Pro Tips for Best Results
- Emojis and some punctuation count differently on certain platforms — leave a few characters of buffer below any limit.
- The SMS 160 limit drops to 70 for non-Latin text on real networks — the bar shows the standard count.
- Instagram shows only the first ~125 characters of a caption in feed — front-load the hook even though the limit is 2200.
- Use the amber zone as a warning, not a target — platforms sometimes count links and mentions extra.
Common Problems & Solutions
Some platforms count emojis, links or @mentions differently — trim a few extra characters below the shown limit.
This tool counts Unicode characters as typed; some apps count display width — check the borderline cases in the app itself.

Text never leaves your browser — counting happens locally with nothing logged or sent.
Frequently Asked Questions
Everything you need to know about using Character Limit Checker
280 characters for standard accounts — the X/Twitter bar here tracks exactly that and shows how many you have left.
150 characters — one of the strictest, and the first bar to go red when you paste a long bio.
100 characters — but titles often truncate visually around 60–70, so check the bar and keep key words early.
160 characters for a standard single SMS; longer messages split into multi-part texts, and Unicode content reduces the real limit to 70.
It counts them as characters as typed — note that some platforms internally weigh emojis as multiple units, so keep buffer below any hard cap.
