Standard banner ad sizes

A reference guide to common display and social ad dimensions and their typical use.

Display advertising uses a set of standard pixel dimensions defined by the Interactive Advertising Bureau (IAB) and supported by networks such as the Google Display Network. Using standard sizes gives an ad access to the widest pool of placements. The tables below list widely used dimensions, where each is typically placed, and general guidance on file weight. Every network and placement enforces its own specification, so each export should be checked against the requirements of the platform it is intended for.

Display sizes

Dimensions are given in pixels as width by height.
Size	Name	Typical use
300x250	Medium Rectangle	One of the most widely used units. Sits within or at the end of article content. Broad inventory across desktop and mobile.
336x280	Large Rectangle	A larger in-content rectangle used in similar placements to the medium rectangle.
728x90	Leaderboard	Placed above or below page content, often in the header area on desktop.
970x250	Billboard	A large, high-impact unit near the top of a page on wide screens.
970x90	Large Leaderboard	A wide header banner for large desktop screens.
300x600	Half Page	A tall sidebar unit with high visibility and strong viewability.
160x600	Wide Skyscraper	A vertical unit placed alongside content in a sidebar.
120x600	Skyscraper	A narrower vertical sidebar unit. Older and less common than the wide skyscraper.
300x1050	Portrait	A large vertical unit used for high-impact placements.
320x50	Mobile Leaderboard	An anchored banner along the top or bottom of a mobile screen.
320x100	Large Mobile Banner	A taller mobile banner with more room for a message.
250x250	Square	A compact square that fits a range of placements.
200x200	Small Square	A small square for tight spaces.
468x60	Full Banner	An older horizontal banner, historically placed above content.

Social sizes

Social platforms scale images to fit, so these are common source dimensions and aspect ratios.
Size	Ratio	Typical use
1080x1080	1:1	Square feed posts on Instagram, Facebook and similar feeds.
1080x1920	9:16	Full-screen vertical stories and reels.
1200x628	1.91:1	Landscape link and feed images on Facebook.
1200x627	1.91:1	Single-image posts on LinkedIn.
1600x900	16:9	Landscape images on X and general 16:9 use.
1000x1500	2:3	Vertical pins on Pinterest.
1280x720	16:9	Video thumbnails and 16:9 previews, such as on YouTube.

File weight guidance

File weight affects how quickly an ad loads and whether a network will accept it. As a general reference, the Google Display Network sets a maximum of 150 KB for display ads, applied to both image and HTML5 units. Many networks also limit animation length, commonly up to 30 seconds, and require animation to stop after looping a small number of times.

To keep files light, favour fewer colours where the design allows, keep the number of frames modest, and compress images before adding them. In this tool, the GIF export includes a target-size control that tunes the output toward a chosen weight per size, along with colour and dithering options.

Network specifications change over time and vary by platform and placement. The figures above are a general reference only. Confirm the current maximum file size, dimensions, animation length and format support for each network before publishing, and test every export in its intended placement.

Open the editor to build an ad at any of these sizes, or return to the home page.
