Google Ads Character Limit (2026 Guide — All Ad Types)

Every Google Ads campaign has a Google Ads character limit that determines how much text you can include in each field. Get it wrong and your ad either gets rejected, truncated, or underperforms because key information never reached the reader.

In 2026, Responsive Search Ads (RSAs) are the primary format for Google Search campaigns — and knowing the Google Ads character limit for each field is the foundation of effective ad copywriting.

This guide covers the exact Google Ads character limit for every ad type and field in 2026, including RSAs, Performance Max, Shopping, Display, and extensions — with practical tips for writing high-converting copy within each constraint.

Responsive Search Ads: Detailed Breakdown

Responsive Search Ads are the default search ad format in Google Ads in 2026. You provide multiple headlines and descriptions, and Google’s AI tests different combinations to find the best performers for each query, device, and user.

Headline: 30 characters

The 30-character headline limit is the tightest constraint in Google Ads. Thirty characters is barely one focused idea — a benefit, a number, a keyword, or a hook. Not three things. Just one.

Google shows 2–3 headlines at a time in the actual ad, displayed side-by-side or stacked. Each headline must make sense on its own AND work alongside any other headline, since Google can combine them in any order.

You must provide at least 3 headlines. Google recommends providing all 15. More headlines = more combinations for Google to test = better optimization over time. Ads with only 3–5 headlines typically receive an “Average” or “Poor” Ad Strength rating, which reduces how often Google enters them into auctions.

Writing effective 30-character headlines

• Include your primary keyword in at least 3 headlines
• Include a benefit in at least 3 headlines (“Free shipping,” “24/7 support”)
• Include a call to action in at least 3 headlines (“Get a quote,” “Book today”)
• Include differentiators in 2–3 headlines (“Since 1998,” “5-star rated”)

Examples within 30 characters:

• Free Character Counter Tool (27 chars)
• Count Characters Instantly (26 chars)
• No Sign-Up Required (19 chars)
• Works on Any Device (19 chars)

Description: 90 characters

Descriptions give you more room to explain. Google shows 1–2 descriptions per ad. Use them to expand on the headline’s promise and include a clear call to action.

The 90-character description limit is enough for one strong benefit plus a CTA:

• Count characters, words, and reading time in real time. Free tool — no sign-up needed. (86 chars ✓)

Front-load the most important information. Google sometimes shows only the first description, and mobile screens may truncate toward the end.

Performance Max: What Changed

Performance Max (PMax) campaigns run across all Google channels — Search, Display, YouTube, Gmail, Discover, and Maps — using a single campaign. The character limits are essentially the same as RSAs, with one addition:

Long Headline (90 characters): Used specifically for Display and Discovery placements where a longer headline fits the visual format. This is separate from the 30-character search headline.

Shopping Ads: Product Title Character Limit

For Google Shopping ads, the product title is the most important field — it determines which searches trigger your product listing.

Product title limit: 150 characters

However, Google typically shows only the first 70–80 characters in standard Shopping placements. Front-load the most important attributes:

Recommended title structure: [Brand] + [Product Type] + [Key Attribute] + [Variant]

Example: Nike Air Zoom Pegasus 40 Men's Running Shoe Blue Size 10 (54 chars)

The product description allows up to 5,000 characters, but the first 500 characters are weighted most heavily for relevance.

Ad Extensions: The Hidden Character Opportunities

Ad extensions (now called “Assets” in Google Ads) expand your ad with additional information. They appear below the main ad text and can significantly increase click-through rates — often without additional cost.

Sitelink Extensions (25 characters)

Sitelinks add extra links below your ad. With only 25 characters per sitelink text and 35 characters per description line, these must be extremely concise:

• Free Character Counter (22 chars ✓)
• Character Counter for SEO (25 chars ✓)

Callout Extensions (25 characters)

Callouts add short phrases highlighting benefits or features:

• No Sign-Up Required
• Works in Real Time
• 100% Free Tool
• Privacy Friendly

Structured Snippets (25 characters per value)

Structured snippets display a list of features under a category header. Values are limited to 25 characters each — keep them tight and factual.

How Character Counting Works in Google Ads

Every character counts: letters, numbers, spaces, and punctuation each use one character.

Emojis count as 2 characters in Google Ads — and Google’s policy restricts emoji use. They are allowed in some formats but must be relevant and not disruptive.

Double-width characters (Japanese, Chinese, Korean) count as 2 characters each. This effectively halves your character budget for non-Latin scripts.

Spaces count. “Free Shipping” is 13 characters, not 12.

How to Write Better Ad Copy Within Character Limits

1. Write 15 headlines immediately — do not self-edit Your first 15 drafts will not all be good. Write them fast, then cut the weakest ones. You cannot edit headlines you have not written.

2. Lead with numbers and specifics Save 40% outperforms Save Money. Specifics build credibility in tight spaces.

3. Use sentence case, not title case Free character counter tool gets more clicks than Free Character Counter Tool in most industries. It reads more naturally.

4. Check every headline in isolation Remember that Google can show any headline next to any other. Read each one alone and ask: does this make sense without context?

5. Always count before submitting Use a character counter tool to verify every field before entering it into Google Ads Manager. The interface does show a counter, but checking in advance saves time and prevents last-minute rewrites inside the platform.
