Definition

Google ad sizes are the pixel dimensions Google accepts for display ads. Uploaded image ads come in 20 set sizes, like 300 x 250 and 728 x 90, and each file must be 150KB or less. Responsive display ads skip fixed sizes: you upload images and Google resizes them to fit.

Also called: Google ad dimensions, Google display ad specs, banner sizes

Two Kinds of Display Ads, Two Kinds of Sizes

Google runs two kinds of display ads, and the size question means something different for each.

An uploaded image ad is a finished picture you make yourself, at an exact size. Google shows it as you made it. So you need one file for each size you want to show in.

A responsive display ad is a kit of parts: images, logos, headlines and descriptions. Google calls responsive display ads "the default ad type for the Display Network" and says they "automatically adjust their size, appearance, and format to fit just about any available ad space." So you do not pick sizes at all. You give Google images in the right shapes, and it builds the ad.

Most stores should start with responsive display ads. One set of images covers almost every spot on the network. Uploaded image ads are for when you need full control over how the ad looks.

Every Uploaded Image Ad Size

These are the sizes on Google's uploaded display ads spec page. File types are GIF, JPG and PNG, and the max file size is 150KB. Google also notes that "some ad sizes will show only in certain regions."

Animated GIF ads have their own rules. Google says the animation "must be 30 seconds or shorter", it can loop but "must stop after 30 seconds", and animated GIFs "must be slower than 5 FPS".

HTML5 ads use the same sizes but need account access first. Google lists the minimums: the account has been open for more than 90 days, has more than $9,000 USD total lifetime spend, and has a good history of policy compliance. Most new stores will not qualify, so plan on image or responsive ads.

Responsive Display Ad Image and Logo Specs

For responsive display ads you upload images in set shapes (aspect ratios), not set sizes. Google lets you upload up to 15 images, and every file can be up to 5120KB.

Text has limits too. Google's setup page asks for up to 5 short headlines of 30 characters or fewer, one long headline of 90 characters or fewer, and up to 5 descriptions. Its best-practice guide also says to keep description text easy to understand, with an 80-character limit.

If you also run Search ads with image assets, those use the same two main shapes: square 1200 x 1200 is required, and landscape 1200 x 628 is "optional but recommended". Google says to put the important part of the picture in the center 80% of the image.

Display Campaigns Are Moving to Demand Gen

One change to know before you build anything new. Google says Display campaigns "are moving to Demand Gen as the Google Display Network (GDN)." From June 2026, eligible advertisers can move existing campaigns with a migration tool. Later, new Display campaigns "can only be created within Demand Gen".

The network does not change. Google says your ability to serve ads on the Display Network "remains the same", across more than 2 million sites and apps. What changes is where you build the campaign. Read our Demand Gen definition for the details.

Store example

Example: A Candle Store Sets Up Display Ads

Made-up numbers, to show the method. A candle store wants to show ads to people who looked at its site but did not buy.

It builds one responsive display ad. It uploads 6 square photos at 1200 x 1200 and 6 landscape photos at 1200 x 628, each a real photo of a candle in a room, not a cut-out on white. It adds a square logo at 1200 x 1200, a 4:1 logo at 1200 x 300, five short headlines like "Hand-Poured Soy Candles" (23 characters) and a long headline under 90 characters.

That one ad can now fill spots from a 300 x 250 box to a 728 x 90 banner. The store makes a few uploaded 300 x 250 and 728 x 90 image ads only for a sale, where it wants the exact design.

Common Mistakes

  • Making 20 banners before trying one responsive ad

    Responsive display ads already fit almost any spot. Start there, then add uploaded sizes only where you need exact control.

  • Text and logos baked into the photo

    Google's guide says to avoid overlaid text and logos, because the parts get mixed in many layouts and small sizes make the text unreadable. Keep the photo clean and put words in the headline fields.

  • Product cut-outs on a plain white background

    Google's guide says to avoid digital composite backgrounds, "including an all-white background", and use real photos with natural shadows and light.

  • Fake buttons in the image

    Google says buttons that promise things like "play" or "close" in an image violate its policy. The whole ad is clickable anyway.

  • Files over the limit

    Uploaded image ads stop at 150KB. Responsive ad images stop at 5120KB. A file one byte over will not upload.

Questions People Ask

Google's uploaded image ads come in 20 sizes. Common ones are 300 x 250 (inline rectangle), 336 x 280 (large rectangle), 728 x 90 (leaderboard), 300 x 600 (half-page ad), 160 x 600 (wide skyscraper) and 320 x 50 (mobile banner). Each file must be 150KB or less.
