Social Media Caption & Character Limits 2026 — Max Length by Platform
Every platform's caption character limit for 2026 in one chart — plus the point where your text gets truncated with a 'more' link.
Caption & character limits 2026 — one chart
This is the current reference for how many characters each major platform allows in 2026: the hard maximum caption length, the truncation point where your text collapses behind a "more" link, and the catch per platform. The ceiling almost never matters — what matters is the visible window before the cut. Both numbers are here.
| Platform | Max characters | Visible before "more" | Notes |
|---|---|---|---|
| Instagram (caption) | 2,200 | ~125 chars | Up to 30 hashtags allowed; 3–5 perform best. First ~125 chars show in feed before the "more" link. |
| Instagram (bio) | 150 | 150 | Entire bio is visible; no truncation. |
| TikTok (caption) | 4,000 | ~100 chars | Raised from 2,200 in 2024. Only ~100 chars show on the For You feed before collapsing. |
| TikTok (bio) | 80 | 80 | Username caps at 24 characters. |
| X / Twitter (standard) | 280 | 280 | Basic accounts; whole post visible. |
| X / Twitter (Premium) | 25,000 | ~280 chars | Premium unlocks long posts; timeline still shows ~280 chars before "Show more". |
| LinkedIn (post) | 3,000 | ~140 chars (mobile) / ~210 (desktop) | "See more" link appears after the first lines; front-load the hook. |
| LinkedIn (headline) | 220 | 220 | Profile headline; fully visible. |
| Facebook (post) | 63,206 | ~480 chars | Very high ceiling; text truncates with "See more" after roughly 480 characters. |
| YouTube (title) | 100 | ~70 chars | Titles over ~70 chars get cut in search and suggested feeds. |
| YouTube (description) | 5,000 | ~157 chars (3 lines) | Only the first 2–3 lines show above "Show more". |
| Pinterest (pin title) | 100 | ~40 chars | Titles truncate in the grid; keep the keyword first. |
| Pinterest (pin description) | 500 | ~50 chars | Description shows in full only on the pin close-up. |
| Threads (post) | 500 | ~500 chars | Whole post visible; links and media count toward the limit differently. |
| Bluesky (post) | 300 | 300 | Grapheme-based count; whole post visible. |
| Snapchat (caption) | 80 | 80 | On-image caption; longer text needs a sticker or link. |
How to read this
Two numbers per platform. The max characters is the hard technical ceiling — exceed it and the post won't publish. The visible-before-"more" number is what actually matters for engagement: it's how much of your caption a scroller reads before deciding to tap. On Instagram that's ~125 characters, on TikTok ~100, on YouTube descriptions just the first 2–3 lines. Front-load your hook, call-to-action, or keyword into that window; everything after the cut is read only by people who already stopped to tap "more".
Which limit bites first
For most creators the ceiling is irrelevant — almost nobody writes 2,200 characters on Instagram or 63,206 on Facebook. The real constraint is the truncation window. The platforms with the tightest useful space are Pinterest (titles cut ~40 chars), YouTube titles (~70 chars), and X standard (280 total). Treat those windows as the design limit, not the published maximum.
