The photos in an Instagram feed are the most classic of all Instagram features. With feed posts, you provide users with regular content, generate continuous interactions, increase engagement and reach, and you can also post advertisements. The optimal image size depends on which format you want to use. Instagram offers three types of images: square, landscape, and portrait.
The following recommended values for Instagram image sizes must be observed:
- Square: 1080 x 1080 pixels as the minimum recommended size with an aspect ratio of 1:1.
- Landscape/Horizontal: 1080 x 560 pixels as the minimum recommended size with an aspect ratio of 1.91:1. The ideal size is 1080 x 608 or 1200 x 628 pixels.
- Portrait/Vertical: 1080 x 1350 pixels as the minimum recommended size with an aspect ratio of 4:5.
In general, it is advisable to post pictures with the highest possible resolution within the framework of the specifications. This will guarantee ideal image quality on different displays. In addition, Instagram’s aspect ratio specifications must be observed, because images will be compressed, stretched, or cropped if they are too large or too small.
