1:1 Aspect Ratio Calculator
Resizing a profile picture, designing a social post, or creating a square logo asset? This 1:1 aspect ratio calculator helps you find perfect square dimensions in pixels for a uniform look.
What is the 1:1 Aspect Ratio?
The 1:1 aspect ratio is a perfect square. The width and height are exactly the same. Square photos became super popular on Instagram, but they've been around since old film cameras. Today, you see squares everywhere: profile pictures, app icons, and even in photo galleries.
Why Use a 1:1 Calculator?
A 1:1 converter makes it easy to crop and size square digital graphics. It is commonly used for:
- Instagram Feed Posts: Size images to clean 1:1 grids for standard Instagram content feeds.
- Profile Pictures: Find standard resolutions for social media avatars and circular crops.
- App Icons: Generate square icons that fit Android and iOS interface design requirements.
- Square Videos: Create videos that fill the screen on Facebook and Instagram feeds without needing to turn your phone sideways.
Common 1:1 Resolutions
Here is a list of the most common 1:1 resolutions, from smallest to largest:
- 150 x 150 (Thumbnail Square)
- 512 x 512 (Standard Web Icon)
- 1080 x 1080 (HD Instagram Post)
- 1200 x 1200 (Facebook Square Post)
- 2048 x 2048 (Hi-Res Digital Print)
For digital social media feeds, 1080 x 1080 pixels is the standard premium quality for square formats. It provides high-contrast grid layouts that look great on any screen device.
Square Sizes for Social Media
Every platform has its own recommended square size. These are the numbers worth remembering:
- Instagram feed post: 1080 x 1080 pixels
- Facebook feed post: 1200 x 1200 pixels
- Instagram grid thumbnails: The grid crops to a square, so keep key content centered at 1080 x 1080.
- YouTube thumbnails are not square (they are 16:9), but channel avatars are.
Avatar and Profile Picture Sizes
Profile pictures are almost always displayed inside a circle or a square box. Uploading a square image keeps your face centered after the circle crop:
- Instagram profile photo: 320 x 320 pixels minimum (upload 1080 x 1080 for sharpness)
- TikTok profile photo: 200 x 200 pixels
- X (Twitter) profile photo: 400 x 400 pixels
- YouTube channel avatar: 800 x 800 pixels
App Icon Sizes
App icons are square by definition. The two sizes you will need most often are:
- iOS app icon: 1024 x 1024 pixels (the App Store master size)
- Android / Google Play icon: 512 x 512 pixels
Use the calculator above to scale any intermediate icon size without breaking the square shape.
Square Video: 1:1 for Moving Pictures
Did you know a square shape works for videos too? A 1:1 video is 1080 pixels wide and 1080 pixels tall. This format looks clean in social feeds because it takes up more space than a horizontal video, and you don't have to turn your phone to watch it. Many video editors let you set the project size to a square, just like a photo.
1:1 FAQ
What is 1:1 in pixels?
Any size where the width equals the height is 1:1. The most common is 1080 x 1080 pixels for Instagram posts, but 512 x 512, 1200 x 1200 and 2048 x 2048 are all 1:1 as well.
What size should an Instagram profile picture be?
Upload a square image of at least 320 x 320 pixels. For the sharpest result, use 1080 x 1080 pixels and keep the face centered, because Instagram crops avatars into a circle.
What size are app icons?
iOS app icons are 1024 x 1024 pixels and Android app icons are 512 x 512 pixels. Both are exact squares (1:1).
