How to Make an Instagram Image the Ideal Size

(Last Updated On: December 19, 2017)

Instagram image — the first image in your blog post

Instagram imageYou want the first image in your blog post to be the same one as your Instagram image. That way there is continuity when people go from your Instagram post to your blog post.

Size of Instagram image

By default, Instagram will crop your image to make it square. If you want an uncropped rectangle, it must be in the proportion of 1.91:1

You don’t want your image to be fuzzy on a large computer screen. So, 300 pixels would be a good height. In that case the width would be 573 pixels. (300 x 1.91)

Change Instagram image size in 8 steps

To change your image size to 571 x 300 pixels, add bars to the bottom or else the sizes. Use either Photoshop or GIMP.  (GIMP is much cheaper.) Here is how to change the size using GIMP:

1. Open image in GIMP

Go to File > Open to open the image that you used in your blog post.

2. Change height to 300 pixels
