Crop an Image to a 9:16 Aspect Ratio

What Is a 9:16 Aspect Ratio?

9:16 means nine units wide for every sixteen units tall. It’s the widescreen 16:9 shape turned upright, and it matches the shape of most phone screens held vertically, so a 9:16 image can fill the display without bars.

It helps to separate the ratio from the resolution. The ratio is the shape; the resolution is how many pixels the image contains. 720 × 1280 and 1080 × 1920 are both 9:16, but the second has more than twice as many pixels and looks sharper on a high-resolution screen.

When to Use a 9:16 Vertical Image

Use 9:16 when the image will be viewed full-screen on a phone, for example:

• Stories and other full-screen vertical posts;
• covers and stills for Reels and other short-form vertical video;
• phone wallpapers and lock screens;
• tall digital signage and vertical banner spaces.

Platforms update their specifications from time to time, so check each one’s current guidance if you need an exact size. For an upright frame that isn’t quite so tall, try 3:4.

How to Crop an Image to 9:16

1. Choose an image or drag it onto the upload area. JPG, PNG and WebP work in every modern browser.
2. The 9:16 frame appears over your photo, already locked to the ratio. Drag it to move it, or drag a corner to make it bigger or smaller. You can also use the zoom slider.
3. Rotate the photo if it’s sideways, and turn on the grid if you want help with composition.
4. Check the output size. It starts at the full size of your crop; type a width or height to make the download smaller, and the other side updates to keep exactly 9:16.
5. Pick JPG, PNG or WebP, then select Download.

Tip: content near the top and bottom of a full-screen vertical image is often covered by profile names, captions or buttons. Keep faces and text toward the middle of the frame.

Cropping vs resizing

Cropping cuts away the area outside the frame and changes the shape to 9:16. Changing the output size then resizes what’s left, scaling it up or down evenly, so nothing is ever stretched. To change only the pixel size of an image without cropping it, use an image resizer; to shrink the file afterwards, an image compressor can help.

Best Pixel Dimensions for 9:16 Images

All of these sizes are exactly 9:16. 1080 × 1920 is a widely used target for phone screens.

If your crop is smaller than the size you choose, the tool tells you the image will be enlarged. Pick a smaller size, or zoom out to keep more of the original.

How to Keep Your Subject in Frame

• Find the vertical line of the photo. A standing person, a tree or a tall building works naturally; a group in a row does not.
• Turn on the thirds grid and place eyes or the main detail near the upper third line.
• Leave space in the direction the subject faces so the picture doesn’t feel cramped.

Cropping Landscape Photos Into Portrait Images

Turning a wide photo into a tall one removes most of it. Cropping a 16:9 landscape to 9:16 keeps only about a third of its width, and a typical 4:3 landscape keeps about 42%. Everything outside that narrow strip is discarded.

That can still work well when the subject is compact: one person, a product or a doorway. If the photo depends on its width, such as a panorama or a group shot, consider a square crop or keep it in 16:9 instead.
