Google display ads come in two main kinds, and they have different size rules. An uploaded image ad is a finished banner that you design at one exact pixel size, so you need a separate file for each slot you want to fill. A responsive display ad is assembled by Google from the images, logos and text you supply, so you upload a few image shapes and Google fits them to the space. This guide lists the sizes from Google's own help pages for both kinds, then gives a short checklist for making files that pass on the first upload.
| Ad type | Size or rule | Notes |
|---|---|---|
| Uploaded image ad, square and rectangle | 200 x 200, 240 x 400, 250 x 250, 250 x 360, 300 x 250, 336 x 280, 580 x 400 | Each banner is a separate file at the exact pixel size. |
| Uploaded image ad, tall | 120 x 600, 160 x 600, 300 x 600, 300 x 1050 | Tall banners that sit beside page content. |
| Uploaded image ad, wide | 468 x 60, 728 x 90, 930 x 180, 970 x 90, 970 x 250, 980 x 120 | Wide banners for the top or bottom of a page. |
| Uploaded image ad, mobile | 300 x 50, 320 x 50, 320 x 100 | Small banners that fit a phone screen. |
| Uploaded image ad, file types | GIF, JPG, PNG | Same list for every size. |
| Uploaded image ad, file size | 150 KB maximum | Applies to each file, so compress large exports. |
| Animated image ad | 30 seconds or shorter, slower than 5 FPS | Rules for animated GIF banners. |
| Responsive display ad, landscape image | 1.91:1, 1200 x 628 recommended, minimum 600 x 314 | The main wide image. |
| Responsive display ad, square image | 1:1, 600 x 600 recommended, minimum 300 x 300 | Used where a square slot fits better. |
| Responsive display ad, square logo | 1:1, 1200 x 1200 recommended, minimum 128 x 128 | Your logo on a square canvas. |
| Responsive display ad, landscape logo | 4:1, 1200 x 300 recommended, minimum 512 x 128 | A wide version of your logo. |
| Responsive display ad, text | Headline 30, long headline 90, description 90, business name 25 characters | Maximum characters for each text field. |
Google Display Ad Sizes: All 20 Banner Sizes and the 150 KB Limit
Pick the ad type first
Decide whether you are uploading finished banners or building a responsive display ad. Finished banners need one file per size from the 20 listed above. A responsive display ad needs a landscape image, a square image, logos and short text, and Google arranges them. Many advertisers prepare both, but the files are different, so make two separate checklists.
Choose the banner sizes you will make
You do not have to make all 20 uploaded sizes. Start with a small set that covers the main shapes: one rectangle such as 300 x 250, one tall banner such as 160 x 600 or 300 x 600, one wide banner such as 728 x 90, and one mobile banner such as 320 x 50. Add more sizes once the first set is working.
Design each size, not just one stretched file
A 728 x 90 banner and a 300 x 600 banner have very different shapes, so the same layout rarely works in both. Rearrange the logo, product and button for each shape. Keep text short, because wide banners are only 90 pixels or less tall, and check every version at its real size before export.
Export as GIF, JPG or PNG under 150 KB
Save each banner as GIF, JPG or PNG, then check the file size. Google rejects uploaded image files over 150 KB. If a file is too heavy, reduce its quality or switch format and look again. For an animated GIF, keep the animation 30 seconds or shorter and slower than 5 FPS.
Prepare the responsive display ad assets
For a responsive display ad, export a 1.91:1 landscape image at 1200 x 628 and a 1:1 square image at 600 x 600, plus a square logo and, if you have one, a 4:1 logo. Count your text: up to 30 characters for a headline, 90 for the long headline and each description, and 25 for the business name.
Use the free tools or Infinall AI to speed it up
If you already have one good image, the free Google Display Ad Resizer turns it into all 20 sizes in one zip, compressed for the 150 KB limit, and the Ad Image Compressor fixes any single file that is too large. The Google Display Ad Mockup previews your copy and image in 20 sizes. If you need a new picture, Infinall AI makes images from a prompt on a Studio canvas, using credits; the Free plan includes 1,000 credits a month with no card.
Google display network sizes: which ones to start with
Google lists 20 sizes for uploaded image ads. They fall into four rough shapes: rectangles and squares (such as 300 x 250 and 336 x 280), tall banners (such as 160 x 600 and 300 x 600), wide banners (such as 728 x 90 and 970 x 250) and small mobile banners (300 x 50, 320 x 50 and 320 x 100). Grouping them this way is our own shorthand to help you plan, not a Google category.
If you have limited design time, cover one size from each shape first. Then add the rest when you know which creative works. If you would rather not design banners at all, a responsive display ad lets Google build the ad in many sizes from a small set of images and text. The trade-off is control: with a responsive ad you do not decide the exact layout of every slot.
Google display banner sizes vs responsive display ad images
Uploaded banners are pixel-exact. A file made at 300 x 250 can only fill a 300 x 250 slot, and you control every pixel of the design. Responsive display ads work from ratios instead: a 1.91:1 landscape image, a 1:1 square image and logos at 1:1 and 4:1. Google combines them with your headlines and descriptions to fit the available space.
Uploaded banners suit brands that need a fixed look, such as a campaign with strict design rules. Responsive display ads suit teams that want broad reach from fewer files. Note that the minimum sizes for responsive images (600 x 314 for landscape and 300 x 300 for square) are minimums, not targets; Google recommends 1200 x 628 and 600 x 600.
The Google display ad size limit: 150 KB per file
Every uploaded image ad must be no larger than 150 KB, whatever its pixel size. This catches people out with large banners such as 300 x 1050 or 970 x 250, and with animated GIFs, which add weight with every frame. Check the file size of each export, not just the first one.
To get under the limit, lower the export quality, cut colours or frames in a GIF, or remove fine detail that will not show at banner size anyway. The free Ad Image Compressor can compress a file to the 150 KB target. Always reopen the compressed file to check that text and the logo are still sharp.
Where Infinall AI fits, and where it does not
Infinall AI can make the pictures and the copy for your display ads from your saved brand, and its free tools handle the resizing and preview steps. It does not buy media for you: you still create and run the campaign in your own Google Ads account. If you already have finished banners from a designer, you may only need the free resizer or compressor, or nothing at all. Infinall AI is most useful when the missing piece is the image or the words themselves.
Frequently asked questions
How many Google display ad sizes are there?
Google Ads Help lists 20 sizes for uploaded image display ads, from 120 x 600 up to 980 x 120 and 300 x 1050. Responsive display ads do not use fixed banner sizes; they use landscape and square images that Google fits to each slot.
What is the most common Google display ad size?
Google's help page uses 300 x 250 as its example size. Google does not publish a ranking of the most popular sizes in the source used for this page, so start with one size from each shape: rectangle, tall, wide and mobile.
What is the file size limit for Google display ads?
Uploaded image display ads can be up to 150 KB each, in GIF, JPG or PNG format. Animated ads must also be 30 seconds or shorter and slower than 5 FPS.
What image sizes do responsive display ads need?
A 1.91:1 landscape image (1200 x 628 recommended, at least 600 x 314) and a 1:1 square image (600 x 600 recommended, at least 300 x 300). Logos are 1:1 (1200 x 1200 recommended) and optionally 4:1 (1200 x 300 recommended).
Can I make all the sizes from one image?
Yes, as a starting point. The free Google Display Ad Resizer turns one image into all 20 sizes in one zip, compressed for the 150 KB limit. Check each size afterwards, because a layout that works in a rectangle may crop badly in a wide banner.
