Character Limits for Social Posts, Ads, and Meta Tags
2026-05-14
Why character count differs from word count and how live limits prevent publish errors.
Platforms count graphemes, bytes, or Unicode code points differently—emoji can explode “character” totals.
URLs in posts may be shortened server-side; preview the final rendered length where possible.
Meta titles and descriptions have display limits in SERPs even when the hard cap is higher.
Trim on a word boundary when you can; abrupt cuts hurt CTR more than being a few chars under max.
