Characters are what you see on screen: an emoji or an accented letter counts once. Sentences are an estimate.

SMS (one message)160 remaining / 160

plain text is 160 per message; one emoji changes it to 70

X is counted the way X counts. The other limits use visible characters, and each network may count emoji or links a little differently, so leave a small margin. Limits change; check the platform if it matters.

Why character count matters

Every platform imposes character limits for a reason — readability, UI constraints, or database field sizes. Knowing your character count before posting saves you from getting cut off mid-sentence, or writing a perfectly crafted tweet only to find it's 3 characters over the limit.

Platform character limits at a glance

  • Twitter / X — 280 characters per tweet
  • Instagram Bio — 150 characters
  • Instagram Caption — 2,200 characters (125 shown before cutoff)
  • LinkedIn Post — 3,000 characters
  • Meta Description — 155 characters (for Google search snippets)
  • YouTube Title — 100 characters (70 shown in search)
  • Facebook Post — 63,206 characters

Tips for social media copy

  • Front-load value — on Instagram and LinkedIn, only the first few lines show before "see more." Put your hook or key message first.
  • Twitter threads — for longer content, break into a thread rather than cramming everything into 280 characters.
  • Meta descriptions — write them as ad copy: include the keyword, a benefit, and a call to action within 155 characters.

Common use cases

Social media managers paste draft captions here before scheduling to confirm they fit Instagram's 2,200-character limit without the preview getting cut. Developers validate database field lengths by checking character counts against their schema constraints before inserting records. SEO specialists use the tool to trim meta descriptions and page titles to the pixel-accurate display limits Google uses in search results. Copywriters paste email subject lines to verify they stay under 60 characters, the threshold where most email clients start truncating in the inbox.

Frequently asked questions

How many characters does Twitter / X allow?
Twitter / X allows 280 characters per tweet for standard accounts. URLs are always counted as characters regardless of their actual length. Twitter Premium (Blue) subscribers can post longer content.
What is the Instagram caption character limit?
Instagram captions can be up to 2,200 characters. However, only the first 125 characters show before the 'more' button — so the most important content should come first. Instagram bios are limited to 150 characters.
What is the LinkedIn post character limit?
LinkedIn posts can be up to 3,000 characters. LinkedIn articles can be up to 125,000 characters. Profile summaries (About section) are limited to 2,600 characters.
What is the ideal meta description length?
Google typically displays 150–160 characters of a meta description in search results. Keep it under 155 characters to avoid truncation. This counter shows 155 as the limit — aim to stay within this for best SEO display.
What is the difference between characters and characters without spaces?
Characters counts every character including spaces, punctuation, and newlines. Characters without spaces counts only non-whitespace characters. Most platform limits count all characters including spaces.
What is the SMS character limit?
160 characters for plain (GSM-7) text. One emoji or non-Latin character switches the message to Unicode encoding and the limit drops to 70. Longer messages are split and billed as segments of 153 (GSM) or 67 (Unicode) characters — which is why marketing SMS costs are counted here at the character level.
How long should a page title be for Google?
Keep the title tag around 50–60 characters — Google truncates by pixel width, and ~60 characters is the practical safe zone. Meta descriptions get roughly 155–160 characters. Both limits are built into this counter's platform presets.
