Character Counter

280 characters for standard Twitter / X posts. URLs always count as 23 characters regardless of length. X Premium subscribers can post up to 25,000 characters, but engagement on long tweets is significantly lower. Our counter shows the standard 280 limit and flags anything over.

30 characters per headline, with up to 15 headlines allowed per responsive search ad. Descriptions are limited to 90 characters, with up to 4 per ad. Headlines can be shown in any combination or order, so aim for 15 unique headlines that work alone and in any pair. Per Google's 2025 responsive ad guidance, ads with 11-15 headlines get 9% more clicks than ads with fewer than 5.

LinkedIn allows up to 3,000 characters per post, but the feed preview truncates after 210 characters with a 'see more' link. Posts between 1,200-1,600 characters consistently get the highest engagement per LinkedIn's 2025 algorithm study. The first 210 characters are everything — they determine whether someone clicks 'see more' or scrolls past.

Yes — almost every platform counts spaces. The single major exception is SMS billing, where the carrier counts the message body without spaces for segment calculation (though the user sees and types the full text). Our counter shows both the total (with spaces) and the no-spaces count so you can see exactly what each platform is measuring.

It depends on the platform. On Twitter, an emoji counts as 2 characters. On Instagram, it counts as 1. On most desktop and web platforms, each emoji is 1 'character' but uses 4 bytes of UTF-8 storage. Our counter counts emoji as 1 character each to match what most editors show, but be aware that if you're targeting SMS, the carrier will reject any message with emoji if it's not in Unicode mode — which reduces your segment limit from 160 to 70 characters.
