Google Ads Character Limits 2026: The Complete Cheat Sheet

Every character limit for every Google Ads format. Live counter, truncation examples, and tricks that save you characters when you are one over the line.

Google Ads is strict about character limits. Go over by one character and your ad will not save. Below is every limit for every Google Ads format in 2026, plus a live character counter you can use right now to test your copy.

Quick Reference: All Limits at a Glance

Every Google Ads character limit in one table. Bookmark it. The sections below go deeper into each format.

Why Character Limits Exist

Ad slots on search results pages are small. A 50-character headline would not fit on a mobile screen. Users also decide to click or scroll in under a second, so a short message lands faster than a long one.

Character limits also push you to be specific. A headline that barely squeezes under the limit with filler words tends to underperform a headline that uses the same space to say something concrete. Google rewards relevance. Every character you waste on filler is a character not spent on something that matters.

Responsive Search Ads (RSA)

Responsive Search Ads are the default search ad format in 2026. You provide multiple headlines and descriptions. Google’s AI tests combinations and shows the best one for each search.

Headlines: 30 Characters Each

Thirty characters is barely a sentence. A headline at the limit usually has one idea in it — a benefit, a number, or a hook. Not three.

Write all 15 if you can. More variations mean more combinations for Google to test. Ads with only 3 to 5 headlines usually get an ad strength of “Poor” or “Average,” which throttles how often your ad actually runs.

Descriptions: 90 Characters Each

Descriptions give you room to explain. Ninety characters is enough for a clear benefit plus a call to action.

Google shows one or two descriptions at a time. Write at least 3 even though the minimum is 2 — more variety means better testing.

Display Paths: 15 Characters Each

Display paths are the words after your domain in the green URL line. They do not need to match real pages on your site. Their job is to add context to what your ad is about.

Truncation: How Ads Shorten on Mobile

Fitting the limits is not the whole job — your ad can still get cut off on smaller screens. Mobile usually shows 2 headlines instead of 3 and one description instead of two. Put your most important message in Headline 1 and Description 1.

Responsive Display Ads

Responsive Display Ads show across the Google Display Network — websites, apps, and Gmail. You upload images, logos, and text. Google reformats them for each ad slot automatically.

You can also upload up to 15 images and 5 logos. These have file size and dimension rules instead of character limits, but text burned into an image still counts visually. If your image is mostly text, Google may reduce delivery.

Performance Max Campaigns

Performance Max runs ads across every Google surface: Search, Shopping, YouTube, Gmail, Display, and Maps. It uses the same asset types as RSA and Display, with videos added in.

The 15-Character Headline Rule

PMax requires at least one headline of 15 characters or fewer. Some banner slots are tiny and a 30-character headline will not fit. Without this short one, Google cannot run your ad in every placement.

Asset Groups and Combinations

PMax organizes assets into “asset groups” the same way RSA uses ad groups. Each group can have its own headlines, descriptions, images, and videos. Google mixes and matches.

Shopping Ads

Shopping ads show a product card: image, title, price, store. Most of the text comes from your Google Merchant Center product feed, not from the ad itself.

Demand Gen Campaigns

Demand Gen campaigns show on YouTube (Shorts included), Gmail, and Discover. The format feels more like social media than search.

Demand Gen gives you 10 extra characters in the headline over standard search ads. Use them. You are competing against cat videos on YouTube and promotions in Gmail. Extra room for a hook matters.

YouTube and Video Ads

Video ad limits change by format.

Text overlays on a video are often more visible than the headline. The 6-second bumper is brutal: 6 seconds of video, 15 characters of headline, and that is all you get.

Ad Extensions and Assets

Extensions (now called “assets” in Google’s newer interface) add extra information below your main ad. They often take up more visual space than the ad itself, so their character limits matter.

Extensions are free. They lift click-through rates and often lower your cost per click because Google rewards more informative ads. Most advertisers underuse them. If your search ads do not have sitelinks and callouts, you are giving up free real estate on the page.

Character-Saving Tips That Actually Work

When you are one character over and cannot cut the message, these tricks help.

Pinning and How It Affects Character Limits

Pinning forces a headline or description to show in a specific position. Headlines can pin to position 1, 2, or 3. Descriptions can pin to position 1 or 2.

Pinning does not change character limits. But it limits how Google’s AI tests combinations, which hurts performance. Pin three headlines to positions 1, 2, and 3 and your “responsive” ad is basically static. Google cannot test new combinations. You lose most of the benefit of RSA format.

Pinning and the 15-Character PMax Headline

In Performance Max, you could pin the 15-character headline to position 1 to guarantee placement. Most of the time you do not need to. Google figures out which placements need the short one.

Common Mistakes That Waste Characters

These show up in almost every audit. Fix them and the ad gets stronger instantly.

How Google Limits Compare to Meta Ads

If you run both Google and Meta campaigns, the limits feel completely different. Google is strict and short. Meta lets you type a lot more but hides most of it behind “…See more”.

The Bottom Line

Character limits feel arbitrary. They are really just a forcing function. A message you cannot fit in the space is usually not specific enough yet. The strongest ads at the limit say exactly what is on offer, exactly who it is for, and exactly what to do next.

Four numbers are worth memorizing: 30 for headlines, 90 for descriptions, 15 for display paths, 25 for business names. Once those are in your head, you can write Google Ads anywhere without a reference.

When you do need a reference, come back here. Use the counter at the top before you paste into Google Ads. Save yourself the error message.
