Social media character limits
Reference table for Instagram, X, LinkedIn, and WhatsApp limits for bios, posts, and ads.
Each social network imposes different limits for bios, posts, comments, and ads. Exceeding the limit blocks publishing or cuts text without a clear warning. An online counter prevents rework.
Quick reference (subject to platform changes)
Instagram — bio: ~150 characters; caption: up to ~2,200. X (Twitter) — post: 280 characters (standard accounts). LinkedIn — headline: ~220; summary: ~2,600. WhatsApp — status: ~700. Meta Ads — titles and descriptions vary by format; always validate with the counter before launching a campaign.
SEO and meta tags
Ideal meta title: ~50–60 characters. Meta description: ~150–160. Google may rewrite snippets, but starting with text within the limit improves predictability in search results.
