Figures as of November 2026. Google values are hard limits. Meta and LinkedIn values are guidance: those platforms allow longer copy in places but fold or truncate it, which is what the guidance numbers protect against. Counts include spaces and count an emoji as one character.
Google Ads: responsive search ad
Meta Ads (Facebook and Instagram)
LinkedIn Ads
| Platform | Field | Limit | Type | Note |
|---|---|---|---|---|
| Google Ads | Headline (responsive search ad, up to 15) | 30 | hard limit | Hard limit per headline. Google combines your headlines automatically. |
| Google Ads | Description (responsive search ad, up to 4) | 90 | hard limit | Hard limit per description line. |
| Google Ads | Display path (2 fields) | 15 | hard limit | Hard limit for each of the two path fields after your domain. |
| Meta Ads | Primary text | 125 | guidance | Guidance: longer primary text is allowed but is often folded behind a See more link, so the first 125 characters carry the message. |
| Meta Ads | Headline | 27 | guidance | Guidance: headlines longer than this are commonly cut off in feed placements. |
| Meta Ads | Description | 30 | guidance | Guidance: the short line under the headline; not shown in every placement. |
| LinkedIn Ads | Introductory text | 150 | guidance | Guidance: the platform allows up to 600 characters, but around 150 is the recommended length before truncation on mobile. |
| LinkedIn Ads | Headline | 70 | guidance | Guidance: the platform allows up to 200 characters; around 70 is the recommended length for sponsored content headlines. |
- 1Paste Google headlines one per line (up to 15) and descriptions one per line (up to 4); each line is counted against its limit.
- 2Fill the two display path fields.
- 3Enter Meta primary text, headline and description, and LinkedIn introductory text and headline.
- 4Fix anything marked over, remembering that guidance limits mean 'likely truncated', not 'rejected'.
"Handmade Soap, Ready to Ship" counts 28 of 30 characters: passes with 2 to spare. "This headline is definitely more than thirty characters long" counts 60 of 30: 30 over, and Google would refuse it.
- Figures are dated November 2026 and platforms change them without much ceremony. If a platform's editor disagrees with this table, the platform wins.
- Counts include spaces and punctuation, and an emoji counts as one character here; some platforms count emoji as more, so leave a small margin when a line is borderline.
- LinkedIn's introductory text technically allows up to 600 characters and its headline up to 200; the table shows the recommended 150 and 70 because that is where truncation starts to bite on mobile.
Because placement decides what shows. In feed placements the text is commonly folded behind a See more link at around that length, so the first 125 characters have to carry the message on their own.
About this tool
The Ad Copy Character Counter checks your copy against the limits and working guidance for Google, Meta and LinkedIn ad fields, as of November 2026. Google's responsive search ad values are hard limits, counted per headline and description line. The Meta and LinkedIn figures are labelled guidance, because those platforms usually fold or truncate long copy rather than refuse it, and the number that matters is where the fold lands.
