Posted by Mike V On February 1, 2023

Google Ads is a key element in many digital marketing strategies, offering a broad range of options for customized banner ads to suit many different purposes.

You probably already know that Google Ads can be an excellent way to reach your target audience and check off some big marketing goals. But what about choosing the best ad sizes? As it turns out, there are specific display ad sizes that perform better than others, making it an important factor to keep in mind.

We’re taking a look at the 10 Google Ads banner sizes you need to know right now, plus giving you a few bonus tips for creating Google Ads that get the job done.

Most Common Google Ads Banner Sizes

The top 10 sizes for banner ads on Google make up a pretty straightforward list:

1. 250 pixels x 250 pixels – Square
2. 200 pixels x 200 pixels – Small Square
3. 468 pixels x 60 pixels – Banner
4. 728 pixels x 90 pixels – Leaderboard
5. 300 pixels x 250 pixels – Medium Rectangle
6. 336 pixels x 280 pixels – Large Rectangle
7. 120 pixels x 600 pixels – Skyscraper
8. 160 pixels x 600 pixels – Wide Skyscraper
9. 300 pixels x 600 pixels – Half-Page Ad
10. 970 pixels x 90 pixels – Large Leaderboard

Understanding Google Ad Sizing

There are some other size options for AdSense publishers in specific regions of the world, primarily countries outside of North America. Also, there are mobile-only ad sizes (such as 320 pixels x 50 pixels and 320 pixels x 100 pixels) that function on certain mobile devices but not desktops or tablets.

You certainly won’t be lacking variety in terms of size options; that much can be said. And while it’s great to have choices, it can also make it challenging to know where to start. But if you’re hoping to prioritize performance (and we’re guessing that you are), there are a handful of ad sizes you’ll want to consider first.

Google’s Top-Performing Banner Ad Sizes

There is an ample amount of information about Google’s display ads, including a list of the top-performing banner ad sizes provided by Google itself.

These five ad sizes are the best in terms of performance:

1. Medium Rectangle

Ad Display Sizing: 300 pixels x 250 pixels

2. Large Rectangle

Ad Display Sizing: 336 pixels x 280 pixels

3. Leaderboard

Ad Display Sizing: 728 pixels x 90 pixels

4. Half-Page Ad

Ad Display Size: 300 pixels x 600 pixels

5. Large Mobile Banner

Ad Display Size: 320 pixels x 100 pixels

Out of these five ad size options, only two are compatible with mobile text and display ads. Most of them offer the benefit of more ad inventory from advertisers, which can work in your favor by boosting earnings when you enable both text and image ads. Some perform better when embedded at the end of articles or within text-based content, while others excel on forum sites.

These details and others are readily available directly from Google, which can make it much easier to decide how and where to use each type of banner ad.

How to Create Effective Google Display Ads

Now that you know more about the top banner ad sizes, it’s time to dig into the process of actually creating an ad. We’ve assembled our four must-have tips for building display ads for a successful campaign, giving you a foolproof guide to getting started with Google Ads – so let’s jump right in.

1. Understand why display advertising is valuable to your strategy.

You might be wondering: are display ads worth the cost? It might be tempting to cut corners – and costs – by skipping display advertising altogether, but that would be leaving a major gap in your digital strategy.

Display ads differ considerably from search ads because they give you the opportunity to curate the fonts, colors, and images that represent your brand, as well as text-based content to communicate a clear message. While they average a lower direct click-through rate than search advertising, they still serve a valuable purpose.

With display advertising, you can remarket to past users while concurrently building brand awareness. Together, these can help propel users down your sales funnel and make conversions more likely in the future.

2. Familiarize yourself with the rules and restrictions for display ads.

Generally, you have a fair amount of flexibility when creating your display advertisements. However, each platform has a few basic rules that you’ll want to be aware of. Otherwise, the time, energy, and money you invested in designing your ads will all be wasted when your selected site rejects them.

For example, all Google Ads must have a file size of less than 150KB. Other Google Ads rules include a ban on ads with a white background and no border outline. On Facebook, display ad images are limited to a maximum of 20% text, including any logos.

3. Design ads that are optimized for both performance and user engagement.

You might think that ad design is easy – but once you’re actually trying to tackle DIY design on your own, it becomes clear that it’s harder than it looks. For this reason (and others), working with a professional is usually the best course of action. Not only can a professional create an aesthetically pleasing, brand-authentic advertisement that effectively connects with your target customers, but they also can likely do it far more efficiently than you.

However, if you’re determined to try designing your own display ads, here are a few of the things you’ll need to consider:

• Color: Aim for a color scheme that captures users’ attention but doesn’t end up being an eyesore. Ideally, your display ad colors should make sense with your branding to avoid confusing users.

• Images and graphics: One of the biggest advantages of display ads vs. search and text ads is the ability to incorporate a visual aspect. So, choose your images and graphics wisely. Look for imagery that conveys a specific message or emotion while communicating a key idea that aligns with ad text.

• Content and ad layout: When in doubt, keep it simple. This is a good rule of thumb for advertising in general, especially when you’re generating content and crafting layouts for display advertising.

• Call to action: Ask yourself what exactly you want internet users to do when they see your ad – what action will they take that fulfills your goal? This is your call to action (CTA) and is one of the most important parts of your banner ad. Make it clear, concise, and easy to spot so that a viewer knows exactly what their next step will be.

Frequently Asked Questions

What are the highest-performing Google Display Network banner sizes?

The top performers in 2026 are 300×250 (Medium Rectangle), 728×90 (Leaderboard), 160×600 (Wide Skyscraper), 320×100 (Large Mobile Banner), and 300×600 (Half Page). Mobile inventory increasingly favors 320×50, 320×100, and 300×250. Run all top-5 sizes plus mobile to maximize inventory coverage.

Can I use a single responsive display ad instead of multiple banner sizes?

Yes, and Google increasingly recommends it. Responsive display ads automatically resize and reformat to fit any placement, including native ad inventory that standard banners cannot reach. Upload 5 headlines, 5 descriptions, multiple images, and a logo, and Google’s machine learning chooses the best combination per placement. Performance typically matches or beats hand-built sized banners.

What is the recommended file size limit for Google Ads banners in 2026?

Google enforces a 150KB maximum for image and HTML5 banner uploads. Static image ads should target 50 to 100KB for fastest load. HTML5 banners can include animation up to 30 seconds but must end on a static frame. Compress images using TinyPNG, MozJPEG, or Squoosh before upload to avoid Google’s auto-compression artifacts.

Should I use HTML5 banners or static images for Google Ads?

Static images are simpler, faster to produce, and load reliably across all placements. HTML5 banners support animation and interactivity and tend to drive higher engagement on premium placements. For most advertisers, start with static images plus responsive display ads. Add HTML5 only when creative team capacity and brand budget justify the production cost.

How many different banner sizes should I upload per Display Network campaign?

Upload at least the top 5 standard sizes (300×250, 728×90, 160×600, 320×50, 320×100) plus a responsive display ad. Adding 300×600 and 970×250 expands premium inventory. Beyond 8 sizes, returns diminish because Google’s machine learning prefers fewer creative variations with high performance signal density.
