Ad height varies significantly depending on placement, platform, and design requirements. Understanding how tall ad units need to be helps marketers and developers optimize visibility and user experience.
This guide explores standard ad dimensions, measurement methods, and best practices for common placements, ensuring your campaigns perform at their best.
| Ad Format | Typical Height | Common Use Case | Platform Examples |
|---|---|---|---|
| Leaderboard | 90 pixels | Top of page on desktop | Display networks, news sites |
| Medium Rectangle | 250 pixels | Content sidebar or mid-article | Publisher ad zones, apps |
| Large Mobile Banner | 100 pixels | Mobile app headers | Mobile games, apps |
| Interstitial | Device height | Full-screen between content | Mobile apps, video campaigns |
| Story Ads | 9:16 ratio | Vertical story feeds | Instagram, Facebook, TikTok |
Standard Web Banner Heights
Web banners are often defined by pixel height, which affects where and how they appear on a page.
Leaderboard and Skyscraper Usage
The leaderboard at 90 pixels sits unobtrusively at the top, while skyscraper units around 600 pixels maximize vertical space on the side.
Responsive Considerations
Responsive designs adapt these heights to fit various screens, preserving aspect ratios and avoiding layout shifts.
Mobile Ad Dimensions
Mobile devices introduce fixed density and safe area constraints that influence how tall ad can be without breaking immersion.
Banners and Adaptive Units
Large mobile banners at 100 pixels fit neatly into app headers, and adaptive banners automatically adjust height based on device and orientation.
Interstitial and Rewarded Ads
Interstitial and rewarded formats occupy the full device height, ensuring the message dominates the screen while remaining easy to close.
In-App and Social Ad Heights
In-app placements and social feeds often rely on flexible units that conform to natural scrolling patterns.
Feed Units and Native Formats
Feed ads typically match the height of organic posts, sometimes expressed as a ratio like 9:16 for vertical story-style placements.
Platform-Specific Guidelines
Each platform provides explicit design specs, which help maintain brand consistency and avoid ad rejection due to size violations.
Ad Height Best Practices
Following standardized height guidelines improves viewability and reduces friction across devices and inventory types.
- Match standard heights to known placements such as leaderboard, medium rectangle, and large mobile banner.
- Use responsive design techniques to preserve aspect ratio and prevent layout shifts.
- Reserve full-screen heights like interstitial for high-impact moments, not continuous exposure.
- Test on real devices to verify safe area insets and rendering across operating systems.
- Align creative production to exact height specifications to avoid cropping or scaling artifacts.
Optimizing Height Across Campaigns
Consistent adherence to height specifications reduces waste and increases compatibility across different inventory sources.
