Free tool
Check your ad copy against every limit
Type your headlines and descriptions once and see exactly where they stand against Google, Meta, and LinkedIn Ads character limits. Free, no signup.
Free, no signup. Nothing you type here is stored.
How it works
Type each field separately
Headlines, descriptions, and primary text each get their own box, matching how ad platforms actually structure a campaign.
Watch the count per field
Each field shows its live character count against its own specific limit as you type.
Spot overages instantly
Any field over its limit turns red immediately, so nothing gets submitted only to be rejected or truncated later.
Why use this tool
Covers three ad platforms at once
Google, Meta, and LinkedIn Ads limits are all in one place instead of checking each platform's help docs separately.
Field-specific limits, not one generic number
Headlines, descriptions, and primary text each have different limits — this checks each one against its own real limit.
Visual warning before you submit
A field turning red is faster to notice than counting characters manually or waiting for a platform's rejection.
Free, unlimited use
Check as many ad variations as you're testing, with no signup and no cap.
Nothing you write is stored
Ad copy is often unreleased and competitive — nothing typed here is saved or sent anywhere.
Built for iterating fast
Ad copy usually goes through several drafts — this is built to check each revision in seconds, not as a one-time setup.
When you'd actually use this
Writing Google Responsive Search Ads
Check up to 15 headlines and 4 descriptions against their exact character limits before uploading them to Google Ads.
Drafting Meta ad primary text
See exactly how much of your primary text shows before the "see more" truncation on most Meta placements.
Testing multiple headline variations
Quickly check several headline options against the limit before running an A/B test.
Preparing a LinkedIn Ads campaign
Check headline and intro text limits, which are stricter than Meta's and easy to accidentally exceed.
Repurposing copy across platforms
Ad copy written for one platform rarely fits another's limits exactly — check it against all three before reusing it.
Tips for best results
- 1Write your strongest message first, then trim to fit — starting with the limit in mind often produces weaker copy than editing down.
- 2For Meta primary text, assume only the first 125 characters will be seen by most people — put your hook there, not at the end.
- 3Google Ads headlines get shuffled and combined automatically — make sure each one can stand alone, not just as part of a specific sequence.
- 4Save copy that's under the limit but close to it — ad platforms occasionally adjust how much text renders based on placement and device.
Frequently asked questions
What is Google Ads' headline character limit?
Each headline in a Responsive Search Ad can be up to 30 characters, with up to 15 headlines per ad, and descriptions up to 90 characters.
How much of a Meta ad's primary text actually shows before truncation?
Roughly the first 125 characters show before a "see more" link appears on most placements, so the strongest hook should come first even though the full text can be longer.
Does going over a limit stop my ad from being approved?
It depends on the platform and field — some hard-cap what you can enter, others truncate visually in certain placements. Either way, staying under the limit avoids your message getting cut off unpredictably.
Is this tool free, and does it save what I type?
Yes, it's free with no signup, and nothing you type is stored — the character counts happen entirely in your browser.
What's the LinkedIn Ads headline limit?
70 characters for the headline, with the intro text typically truncated around 150 characters on most placements before a "see more" link appears.
Do emojis in ad copy count differently toward the limit?
Character counting for emojis can vary slightly by platform's internal encoding — this tool counts raw character length, which is a close but not guaranteed-exact match for every platform's own counter.
Can I use the same headline across Google, Meta, and LinkedIn?
Only if it fits the tightest of the three limits — Meta's 40-character headline limit is the most restrictive, so writing to that length first makes reuse across platforms easier.
Why does my ad look cut off even though I'm under the character limit?
Some platforms truncate visually well before the technical character cap, especially on mobile devices with narrower ad units — this is exactly why the tool notes both the hard limit and where visible truncation tends to happen.
