The best ad sizes for XenForo depend on where you plan to display the ads (header, sidebar, thread, footer, etc.), but the most effective and high-performing ad dimensions (especially for Google AdSense or other ad networks) typically include:
Recommended XenForo Ad Sizes (Width x Height in pixels)
| Placement Area | Suggested Size (px) | Description |
|---|---|---|
| Header / Top | 728×90 | Leaderboard – good for desktop |
| 970×90 / 970×250 | Large leaderboard / Billboard | |
| Sidebar (Right Panel) | 300×250 | Medium Rectangle – popular for sidebars |
| 300×600 | Half Page – taller sidebar ad | |
| In-Thread (Inline) | 336×280 | Large Rectangle – works well inside content |
| 300×250 | Medium Rectangle – commonly used in-thread | |
| Mobile Responsive | 320×100 | Large Mobile Banner |
| 320×50 | Mobile Leaderboard | |
| Footer | 728×90 or 970×90 | Good for bottom of pages |
Tips for XenForo Ads
- Use responsive ad units for mobile-friendliness.
- Avoid placing too many ads close together to comply with Google AdSense policies.
- Test different sizes with A/B testing to see which gives you the best CTR (click-through rate).
- XenForo also supports HTML, JS, or AdSense code in its "Advertising" admin section under Appearance > Advertising.
