Social Media Character Limits in 2026 (Complete Chart)
X, Instagram, LinkedIn, YouTube, TikTok, and ad platforms — current character limits and how to write inside them.
Character limits force clarity. Platforms update them occasionally, so treat any chart as a working guide.
On X, standard posts sit near 280 characters while Premium tiers allow much longer text. Instagram captions allow thousands of characters, but the feed truncates early.
YouTube titles work best under about 60–70 visible characters even if the hard limit is higher.
Paid social is stricter. Meta ad headlines and primary text reward brevity because UI truncates aggressively on mobile.
Use a counter with platform presets while drafting, then do a final check in the native composer.
