Where the 4:1 aspect ratio is used
4:1 is a very narrow strip that grabs attention horizontally without using much height. The LinkedIn personal cover image size of 1584 × 396 px is 4:1.
- LinkedIn covers: The 1584 × 396 px personal profile background.
- Website headers: Ultra-slim hero sections on minimal landing pages.
- Ad banners: Billboard-style strips; the 970 × 250 billboard is close to 4:1.
- Signage and UI: Stadium ribbons, tickers and long in-game bars.
4:1 resolution cheat sheet
| Name | Width × height | Typical use |
|---|---|---|
| 4:1 at 728 wide | 728 × 182 px | Slim strip at leaderboard width |
| LinkedIn cover | 1584 × 396 px | LinkedIn personal profile background |
| Web banner | 2000 × 500 px | Ultra-wide web app headers |
| High resolution | 4000 × 1000 px | Sharp assets for very wide screens |
Tip: The standard 728 × 90 leaderboard is about 8:1, not 4:1. Use 4:1 for headers and covers, and check each ad network's exact size list.
How to calculate 4:1 dimensions
Height = width × 1 ÷ 4. Width = height × 4 ÷ 1. Round to whole pixels; many video encoders also need even numbers.
