Instagram image — the first image in your blog post
You 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
Go to Image > Scale Image to change the height to 300 pixels
3. Decide upon colour of bars
Drag eyedropper tool from Toolbox to picture. Select a colour for your bars.
4. Change background colour
Use double-headed arrow to move colour to background colour

c. Change width to 573
6. Copy & paste image onto new rectangle
