Social Media Character Counter

Social media character limits — full 2026 reference

Every social platform caps how long a post, caption, bio, or title can be. The counter above is live — paste your text once and see how it fits across every platform you publish to. Use the toggle to switch between standard and verified (X Premium) limits.

Why character limits matter

Going over a limit means your post won't publish at all. Staying under but close to the limit means readers see "...see more" before your hook. Most platforms truncate well below the hard cap — what shows in the feed is often a small fraction of the limit. Hook, value, and call-to-action all need to fit inside that visible slice.

Visible-before-truncation cheat sheet

• X / Twitter: All 280 chars visible. Premium posts truncate after first ~280 chars with "Show more".
• Instagram caption: ~125 chars before "more".
• Facebook post: ~480 chars before "See More". First 80 chars get highest engagement.
• LinkedIn post: ~210 chars on desktop, ~140 on mobile before "...see more".
• TikTok caption: ~80 chars before "more".
• YouTube description: ~100-150 chars above the fold before "Show more".
• Pinterest pin title: ~50-60 chars in feed view.

X (Twitter) verified vs non-verified

X is the only major platform with a real character-limit difference between standard and paid accounts:

• Standard: 280 characters per post.
• X Premium (formerly Twitter Blue): 25,000 characters per post — essentially long-form articles inside a tweet.

Toggle the "X Premium / Verified" switch above the platform list to see your post measured against the 25,000-character ceiling. Be warned: long-form X posts truncate after the first ~280 chars in the feed with a "Show more" — the first 280 chars still need to stand alone.

URL counting rules

• X: URLs always count as exactly 23 characters, no matter how long the actual URL.
• Mastodon: Same — 23 characters per URL.
• Threads, Bluesky, Instagram, LinkedIn, Facebook, TikTok: URLs count their full length.

Why schedule with limits in mind?

Crafting one post that fits every platform's truncation point lets you batch-schedule the same content across X, LinkedIn, Threads, and Instagram with one click — without reformatting per platform. So-me Studio schedules to all 7 major platforms from one editor, auto-reformats for each platform's quirks, and stays free up to 15 posts per month.
