Convert an image to 2:1 ratio
A 2:1 ratio is exactly twice as wide as it is tall. It is a common shape for website header banners and blog hero images, and it is also a natural fit for panoramic landscape photography, where the scene is naturally much wider than it is tall.

How to convert your image to 2:1 ratio
Upload your image using the tool above.
If your source photo is a wide landscape, crop mode will trim a small amount from the top and bottom to center on the 2:1 frame.
For square or portrait photos, pad mode keeps the full image visible inside the wide canvas.

Why do you need to convert to 2:1 ratio?
Website hero banners, blog post headers, and email newsletter tops all expect a wide, short image — and 2:1 is the ratio that fits these placements most naturally. Using the wrong ratio means the platform either stretches, crops, or adds bars to your image automatically, none of which gives the result you designed.
Common pixel sizes for this ratio (2:1)
Where this ratio is used
- Twitter/X profile header banners
- Website hero and header banner images
- Panoramic landscape and travel photography
- Email newsletter header graphics
Crop or pad — which should you use for this ratio?
A 2:1 crop works well when the subject sits roughly in the center of a wider photo. If your photo is square or portrait, padding is usually the better option since cropping to 2:1 would remove roughly half the image's height.
How this ratio compares to a similar one
2:1 vs 1.91:1: they look almost identical, but 1.91:1 is the precise ratio platforms like Facebook and LinkedIn expect for link-preview ads, while 2:1 is a more general-purpose wide banner ratio for headers and hero images. Use 1.91:1 specifically for ad placements.
Frequently asked questions
Is 2:1 the official Twitter/X header size?
Twitter/X recommends 1500×500 px for header images (a 3:1 ratio), but many designers use the close 2:1 ratio interchangeably for general banner work since the platform crops and scales the upload regardless. Check current platform specs before finalizing a header.
How is 2:1 different from 21:9?
2:1 is less extreme — about twice as wide as tall, while 21:9 is roughly 2.33 times as wide. 2:1 tends to look more like a "wide photo" while 21:9 looks distinctly cinematic.
What happens if I upload a square photo and convert it to 2:1?
A square photo cropped to 2:1 loses half its height. If the subject fills the whole square frame, padding instead of cropping keeps more of the image visible, just with added side or top/bottom space.
What's the difference between 2:1 and a 'panorama' photo?
A panorama is usually much wider than 2:1, often 3:1 or more. 2:1 is a moderate wide ratio suited to banners, while true panoramas need a much more extreme ratio to look natural.
Can I use a 2:1 image as an email newsletter header?
Yes — 2:1 (or close to it) is a common newsletter header shape since it displays cleanly at the top of an email without taking up excessive vertical space on mobile.
