Square images
Before Instagram became popular, you used to be able to publish only square images. Right now, you can post portrait and landscape photos as well. However, if you’re still one of those who love to have a very instagram-ish Instagram profile, the square image dimensions are 1080 pixels x 1080 pixels.
Portrait and landscape Instagram images
If you are not the square image type of person, you should know that Instagram offers you two other different options: portrait or landscape images. All you have to do is keep your visuals at 1080 pixels in width. For portrait images, the size is 1080 pixels x 1350 pixels, while the landscape image is set at 1080 pixels x 566 pixels.
Stories
Vertical content is on the rise thanks to smartphones and Instagram stories. You can create videos, photos, text or animated images that “roll” for 24 hours before “expiring”. If not saved, stories will be automatically deleted from your account. If you want to create Stories for Instagram, you have to make sure that you will use the most fitting size: 1080 pixels x 1920 pixels (aspect ratio 9:16).
