Character & Word Counter
Check your ad and social copy against Google, Meta, LinkedIn, X and YouTube limits — live, before you publish.
Limits verified in 2026 and shown per field. Where a platform hides text after a shorter “visible” point (e.g. Meta primary text after ~125 chars, before “See more”), that fold is marked. Some limits vary by ad placement or objective, and platforms change specs over time — confirm the final count inside the actual ad platform before publishing. On X, links always count as 23 characters via t.co, so a post with a long URL will count lower there than the raw number shown.

Frequently Asked Questions
Why do different platforms count characters differently?
Each platform sets its own limits per field, and many have two numbers: a hard maximum you cannot exceed, and a shorter visible length after which your text is hidden behind a \u201cSee more\u201d link or simply cut off. For example, a Meta primary text can technically run to thousands of characters, but only about 125 show on mobile before truncation \u2014 so the practical limit is far lower than the hard cap. This tool shows both where they differ.
What are the Google Ads character limits?
For Responsive Search Ads in 2026: each headline is 30 characters (up to 15 headlines), each description is 90 characters (up to 4 descriptions), and each display URL path is 15 characters (up to 2 paths). These are hard limits \u2014 the Google Ads editor will not let you exceed them \u2014 so counting before you paste saves rewriting inside the platform.
What is the difference between the visible count and the hard limit for Meta ads?
Meta (Facebook and Instagram) ads have generous hard maximums but truncate visually much sooner. Primary text shows about 125 characters on mobile before \u201cSee more\u201d; the headline shows around 27 and caps at 40; the link description shows around 27 and caps at 30 and is often hidden entirely on mobile. Meta's own guidance is to write for the visible window, so this tool flags when you pass the visible fold, not just the hard cap.
Does a URL count as its full length on X (Twitter)?
No. On X, any link counts as 23 characters regardless of how long the actual URL is, because X wraps links in its t.co shortener. This counter shows the raw character count; if your post contains a long link, your effective X count will be lower than the raw number shown \u2014 subtract the link's real length and add 23.
Are these limits guaranteed to be current?
The limits here were verified in 2026, but ad platforms change their specs periodically and some limits vary by ad placement or campaign objective. Use this tool as a fast pre-check, then confirm the final count inside the actual ad platform's editor before publishing an important campaign.
