Character Limits Cheat Sheet: X/Twitter, SMS, Google, Instagram and More
By the LazyTools team · Published 2026-07-05 · Updated 2026-07-05 · 4 min read
The numbers to remember: an X post is 280 characters, one SMS is 160, Google shows about 60 characters of a title and 155–160 of a meta description, and Instagram captions run to 2,200 — of which only ~125 show before ”… more”. Draft against any of them live with the character counter, which tracks these limits as you type.
The cheat sheet
| Platform / field | Limit | The catch |
|---|---|---|
| X / Twitter post | 280 | URLs = 23 flat; emoji = 2; Premium longer but folds at ~280 |
| SMS (single) | 160 | any emoji → 70; multipart segments carry 153 (or 67) |
| Google title | ~60 shown | pixel-based truncation (~600 px), not a hard cap |
| Meta description | ~155–160 shown | pixel-based; mobile shows less |
| Instagram caption | 2,200 | feed folds at ~125; 30-hashtag cap |
| YouTube title | 100 | ~70 visible in most listings |
| YouTube description | 5,000 | first ~157 show in search |
| LinkedIn post | 3,000 | folds after ~210 in the feed |
| Facebook post | 63,206 | folds after ~250; famously precise cap |
| Pinterest description | 500 | ~50–60 visible in grid |
Two patterns run through the table: hard caps (SMS, X) where the platform refuses more, and visibility folds (Google, Instagram, LinkedIn) where you can write more but nobody sees it. The second kind rewards front-loading far more than trimming.
The two traps that surprise everyone
The emoji/SMS trap. Standard SMS uses GSM-7 encoding: 160 characters per message. The moment your text includes a character outside that set — an emoji, curly quotes, many accented letters — the entire message re-encodes as UCS-2 and the limit drops to 70. Long messages then split into segments of 153 (GSM) or 67 (UCS-2) characters, and bulk-SMS services bill per segment: one 🎉 in a marketing blast can double the invoice.
The X link trap. On X, every URL is counted as exactly 23 characters via the t.co wrapper — whether the link is 15 characters or 200. Budget 280 − 23 = 257 for your words per link, and remember most emoji cost 2.
How to draft against a limit (the workflow)
- Write freely first — editing down beats padding out.
- Paste into the character counter — the limits panel shows characters left (or over) for each platform live.
- For X: subtract 23 per link from what the counter shows; for SMS: strip emoji or accept 70s.
- For Google fields: put the message in the first 50 characters — survival under pixel truncation is about order, not just length.
- Final check in the platform’s own composer — it enforces its own arithmetic.
For word-based limits (essays, abstracts, ad copy word caps), the word counter tracks words, sentences and reading time the same way.
Writing short: what actually helps
Cutting characters without losing meaning is a skill with three reliable moves: delete throat-clearing openers (“We are pleased to announce that” → nothing), prefer strong verbs over noun phrases (“made a decision” → “decided”), and replace conjunctions with punctuation (“and additionally” → ”—”). A 320 character draft usually contains a 260-character message.
Common mistakes
- Counting words when the limit is characters (or vice versa) — SEO titles are characters/pixels, essay limits are words.
- Forgetting spaces count — “characters with spaces” is the number platforms enforce.
- Trusting the emoji to cost 1 — it’s 2 on X and it nukes SMS encoding entirely.
- Treating Google’s ~60/~158 as hard caps — they’re visibility folds; write for the fold, don’t fear it.
- Padding to reach a limit — limits are ceilings, not targets; shorter almost always reads better.
Quick summary
Memorize four numbers — 280 (X), 160 (SMS), ~60 (Google title), ~158 (meta description) — and the two traps: links cost 23 on X, and one emoji turns an SMS into a 70-character message. Draft with the character counter’s live limit tracking, front-load anything Google will truncate, and let the platform composer make the final call.

Frequently asked questions
What is the character limit on X (Twitter)?
280 characters for standard accounts. Every URL counts as 23 characters regardless of length, and most emoji count as 2. Premium subscribers can write much longer posts, but only ~280 characters show before the 'Show more' fold.
Why is one SMS 160 characters?
The GSM standard packs 160 seven-bit characters into one 140-byte message. Include any character outside the GSM set — most emoji, many accented letters — and the whole message switches to 70-character UCS-2 encoding.
How long should a meta description be?
Google truncates by pixel width, not a character count — roughly 155–160 characters usually fits on desktop, less on mobile. Front-load the key message; longer text isn't penalized, just cut visually.
How long can an Instagram caption be?
2,200 characters (and up to 30 hashtags) — but the feed collapses everything after roughly 125 characters behind '… more', so the opening line does all the work.
Do spaces and punctuation count as characters?
Yes — on effectively every platform, a character is a character, spaces included. Some style guides also quote 'characters without spaces'; the character counter shows both.
Why does my count differ from the platform's count?
Platforms count some things specially: X's fixed 23 for links, emoji counting as 2, invisible formatting characters in pasted text. Use a counter for drafting, and treat the platform's own composer as the final referee.
Do these limits change?
Occasionally — X famously doubled from 140 to 280 in 2017. The figures here are the widely documented values as of mid-2026; the platform's help pages are the canonical source.
