Twitter is 280, but tweets with images feel different. LinkedIn gives you 3,000 characters for posts, but only 220 display before "See more." Meta descriptions can be 160 characters, but Google often ignores them anyway. Here's a practical reference for the limits that actually matter, and what they mean for how you write. Social media character limits Twitter / X Element Limit Tweet 280 characters Tweet with media 280 characters (URLs count as 23 characters regardless of length) Twitter Blue / X Premium Up to 25,000 characters (subscribers only) Bio 160 characters Display name 50 characters Username 15 characters Important: Twitter replaces all URLs with a t.co short link of exactly 23 characters, no matter how long or short your URL is. So https://a.co and a 200-character URL both consume 23 characters. Practical advice: Target 220–240 characters for a tweet so it feels complete without being truncated on mobile preview cards. LinkedIn Element Limit Post 3,000 characters Post preview (before "See more") ~220 characters on feed Article title 150 characters Headline 220 characters Summary / About 2,600 characters Comment 1,250 characters Practical advice: Put your hook in the first 150–200 characters of a post — that's what displays before the reader has to click "See more." A wall of text with no break before that threshold will kill engagement. Instagram Element Limit Caption 2,200 characters Caption preview (before "More") ~125 characters Bio 150 characters Username 30 characters Hashtag per post 30 hashtags Facebook Element Limit Post 63,206 characters Comment 8,000 characters Page name 75 characters Page description 255 characters Bluesky Element Limit Post 300 characters Bio 256 characters Display name 64 characters SEO / web metadata limits These limits are guidelines, not hard rules — search engines use their own rendering logic — but they're widely accepted as practical targets. Meta title (title tag) Character limit: 50–60 characters Pixel limit: Google displays roughly 600px width Why it matters: Titles truncated with "..." look unprofessional in SERPs. Keep your most important keyword near the start. <title>URL Encoder / Decoder — Encode & Decode URLs Instantly</title> Enter fullscreen mode Exit fullscreen mode Meta description Character limit: 150–160 characters (some sources say up to 320 for mobile) Pixel limit: ~920px for desktop Why it matters: Google frequently rewrites meta descriptions if they don't match the search query. Write a compelling description that accurately summarises the page — Google uses it as a signal even when it doesn't display it verbatim. <meta name="description" content="Encode or decode URLs and query parameters instantly.
