# Why I see "The aspect ratio is not supported" for my Instagram Auto post?
Instagram's accepted aspect ratio range for images is between 4:5 and 1.91:1, or as numerical values between 0.8 and 1.91. To calculate the aspect ratio of an image, divide its width by its height.
You see The aspect ratio is not supported because your product image does not meet the Instagram criteria. Your product images don't need to be a specific pixel size, as long as the aspect ratio falls within the acceptable range. Square images of any size, portrait images with an aspect ratio between 0.8 and 0.99, and landscape images with an aspect ratio between 1.01 and 1.91 will work nicely on Instagram.
