Ultimate Ads Character Counter Guide for Marketers (2026)

The Cost of Truncated Ads

You've spent hours perfectly crafting the headline for your new ad campaign. The hook is brilliant, the offer is compelling, and the call to action is irresistible. But when the ad goes live on Facebook or Google, your masterpiece is cut off with a brutal "..." right before the punchline.

Truncated ads destroy click-through rates. When your audience can't see the value proposition or the CTA, they keep scrolling. Every character over the limit is wasted ad spend.

Why Generic Word Counters Fail Marketers?

Most copywriters write their ads in Google Docs or Microsoft Word. While these tools have built-in word and character counters, they are virtually useless for digital advertising because they don't map to platform-specific limits.

Google Docs won't warn you that your Google Ads Headline just hit 31 characters (the limit is 30). It won't tell you that your Facebook Ad primary text will be hidden behind a "See More" button because it crossed the 125-character threshold.

Current Ad Character Limits by Platform

To maximise the impact of your ad spend, write within the platform's strict limits. Here are the core limits you need to memorise (or use a tool to track):

Google Search Ads

Headlines (up to 15): 30 characters maximum.
Descriptions (up to 4): 90 characters maximum.
Path (Display URL): 15 characters each.

Facebook & Instagram Ads

Primary Text: 125 characters (anything longer risks being hidden behind "See More").
Headline: 40 characters (longer headlines risk truncation).
Description: 30 characters.

LinkedIn Sponsored Content

Introductory Text: 150 characters for desktop (anything longer gets truncated).
Headline: 70 characters.
