Poor picture quality when sharing pictures to Instagram

Pictures shared on Instagram are restricted to specific horizontal and vertical image dimensions. The preferred vertical and horizontal pixels have been determined by Instagram and are set to four different dimensions. For more details, see the explanation below.

Before you try the recommendations below, be sure to check if your device's software and related apps are updated to the latest version. To update your mobile device's software, follow these steps:

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install.

Step 3. Follow the on-screen instructions.

Instagram’s horizontal and vertical picture dimensions

Instagram recommends a total of four image dimensions to users. They are 1:1, 4:5, 1.91:1, and 9:16. When sharing pictures outside of these dimensions, the pictures automatically adjust to the set dimensions and may be cut off in the process.

Instagram picture’s width

The optimal width of a picture to share on Instagram is 1080 pixels. If a user shares a high-resolution picture, the picture’s resolution will automatically be compressed to 1080 pixels. Through this process, the quality of the photo may appear reduced, especially compared to the original.
