The 728×90 pixel leaderboard is the standard horizontal banner for desktop websites. It typically appears at the top of a page, above or below the navigation. It's the second most common display ad size after the 300×250 medium rectangle.
- •Design for desktop only — mobile uses 320×50 instead. Always create both sizes for full coverage.
- •Use the horizontal space for a left-to-right flow: logo → message → CTA button.
- •Keep file size under 150KB. The narrow height (90px) means text must be 14px+ to be readable.
What you need to know
The 728×90 leaderboard is a desktop-only format — it's too wide for mobile screens (which use 320×50 or 320×100 instead). It dominates the top-of-page ad position on news sites, blogs, and forums. The wide, horizontal format is ideal for brand messaging with a logo, tagline, and CTA arranged left to right.
Because the leaderboard sits at the very top of the page, it gets high impression counts but can suffer from 'banner blindness' — users habitually skip over the top banner area. To combat this, use motion (animated GIF or HTML5), bold colors that contrast with typical website headers, and a strong, specific CTA rather than generic 'Learn more' text.
The 728×90 format has been a web advertising staple since the early 2000s. Despite the rise of responsive and native ads, it remains one of the highest-volume ad slots in the Google Display Network. Some publishers also support the wider 970×90 'super leaderboard' in the same position.
