Character Limits for Every Social Platform (2026)
The current character limits for X, Instagram, TikTok, LinkedIn, YouTube, and more — plus SEO title and meta description limits, and how to write to them.
The limits that matter most
Every platform enforces its own ceilings, and hitting them mid-thought is the fastest way to ruin a post. The big ones: X allows 280 characters per post for standard accounts (25,000 for premium subscribers) and 160 for bios. Instagram captions technically allow 2,200 characters, but only the first ~125 show before the '...more' fold — the rest is invisible unless tapped. Instagram bios get 150 characters.
TikTok captions allow up to 4,000 characters, though short captions still dominate. LinkedIn posts cap at 3,000 characters with roughly the first 200 visible before 'see more'; LinkedIn headlines get 220. YouTube titles cap at 100 characters, but only about 70 display in most search results. A single SMS segment is 160 characters (70 if you include emoji or special characters), after which messages split and may arrive out of order.
SEO limits: titles and meta descriptions
Google doesn't enforce a character limit — it enforces a pixel width, which works out to roughly 55–60 characters for titles and 155–160 for meta descriptions before truncation. Go over and Google cuts your text mid-sentence with an ellipsis, or worse, rewrites it entirely.
The practical targets: keep titles under 60 characters with the primary keyword near the front, and meta descriptions between 120 and 155 characters — long enough to make a case, short enough to survive intact. The character counter on this site includes live progress bars for both limits.
Writing to a limit without sounding truncated
The goal isn't to fill the limit — it's to front-load the payoff. On every platform with a fold (Instagram's ~125 characters, LinkedIn's ~200), the text above the fold has one job: earn the tap. Put the hook, claim, or question first and the context after.
When you're over the limit, cut in this order: filler adverbs (very, really, actually), redundant qualifiers, and prepositional phrases that restate the obvious. Swapping 'in order to' for 'to' and 'due to the fact that' for 'because' buys 15+ characters with zero meaning lost. Numerals ('5' not 'five') and ampersands help in titles.

Frequently asked questions
Do emoji count as one character?
Usually more than one. Many emoji are made of multiple Unicode code points, and platforms count them differently — X counts most emoji as 2 characters, and in SMS a single emoji switches the whole message to 70-character segments. When you're near a limit, test with the emoji included.
Do links count against X's 280 characters?
Yes, but every link is normalized to 23 characters regardless of its actual length, thanks to the built-in shortener. So a long URL costs the same as a short one.
Is it bad to max out Instagram captions?
Not inherently — long storytelling captions perform well in some niches. What matters is that the first ~125 characters work as a standalone hook, since that's all anyone sees before choosing to expand.
