Guide to Google Display Ad Sizes & Specs

Google offers several Display ad formats on its network, each with specific technical requirements. Advertising can be divided into four distinct categories.

1. Brand awareness

2. Lead generation

3. Affiliate marketing

4. Retargeting

This guide breaks down all current Google display ad sizes and types

Image Quality

• Images should be clear and legible.

• Avoid excessive text or any text that’s too small to read.

• No blinky/flashing effects in static images (those require using the animated ad formats).

• Google disallows certain tricks like fake buttons or imitation of OS alerts in ad images.

• Ensure your ad artwork has a distinct border if it’s the same color as the page background (to avoid blending into webpage content).

Leaderboard (728 x 90)

A leaderboard ad is a wide display unit in Google Ads that spans the full width of a webpage’s content area. Positioned at the top—or occasionally the bottom—of a page, it appears above the fold and is among the most visible ad placements. Available in static, animated, or rich media formats, leaderboard ads are commonly used to promote key offers or highlight products to a broad audience.

Footer (728 x 90)

Footer ads offer a subtle yet effective way to capture user attention without disrupting their browsing experience, especially when supported by clear messaging, responsive design, a strong call to action, and precise targeting. While successful campaigns can provide useful inspiration, the most impactful footer ads are those tailored specifically to your brand and audience, helping you stand out in this valuable on‑page space.

Skyscraper (160 x 600)

A skyscraper ad is a tall, vertically oriented display ad that appears along the side of a webpage, usually beside the main content. Designed to be bold and attention‑grabbing, these ads are commonly used to promote high‑value products or services. Skyscraper ads work especially well for reaching users who are actively browsing or researching online. They play a key role in digital marketing thanks to their strong visibility, ability to boost engagement, precise audience targeting, and contribution to overall brand awareness.

Rectangle (300 x 250)

A rectangle ad is a type of display advertisement that is rectangular in shape, typically used in online advertising. These ads are designed to fit into the available space on websites and are often used in various online environments, including desktops, tablets, and smartphones. Rectangle ads are versatile and can be placed in different locations on a webpage, such as above the fold, at the bottom of the page, or within other ad types.
