## Definition

1:1 is a square aspect ratio: the width and height are equal. A common size is 1080 x 1080 pixels.

## 1:1 sizes in pixels

| Width x height | Where it comes up |
| --- | --- |
| 480 x 480 | Google's minimum for square video ads on YouTube |
| 640 x 640 | TikTok's minimum for square in-feed ads |
| 1080 x 1080 | Google's recommended size for square video ads |
| 2160 x 2160 | 4K square, for a larger master file |

Any size with equal width and height is 1:1. A larger export does not add detail the source never had.

## Extended Definition

Square was Instagram's original format, and YouTube and TikTok both accept it today. It takes up more of a phone screen than 16:9 because it is taller, and less than a full-screen 9:16 video. YouTube counts square videos up to three minutes as Shorts.

To make a square version of a 16:9 video, crop the sides or fit the whole frame with space above and below. Cropping a 9:16 video to 1:1 removes the top and bottom, so keep faces and captions near the middle. BlitzReels projects can use 1:1 alongside 9:16 and 16:9.

## FAQ

### What size is a 1:1 aspect ratio?

1:1 has no single size, because any frame with equal width and height is 1:1. Common sizes are 1080 x 1080 and 720 x 720 pixels. Google recommends 1080 x 1080 for square video ads on YouTube.

### Is 1:1 square?

Yes. 1:1 means one unit of width for every unit of height, so the frame is a perfect square.

### Do square videos count as YouTube Shorts?

Yes. YouTube categorizes square and vertical videos up to three minutes long as Shorts if they were uploaded on or after October 15, 2024.

### How do I turn a 16:9 video into 1:1?

Crop the sides around the subject, or fit the whole frame inside a square canvas with space above and below. Cropping removes content from the edges, and fitting keeps everything at a smaller size. Avoid stretching the image to fill the square.
