Question

What is a 4:5 aspect ratio used for?

4:5 is a slightly tall portrait shape. It is the recommended feed shape for Facebook and Instagram image ads, at 1440 x 1800 pixels, one of LinkedIn's recommended ad ratios, and the shape of 8 x 10 inch and 16 x 20 inch prints.

Because it is taller than square but not full screen, 4:5 takes up more of a phone feed than a square image while still showing as a normal post rather than a full-screen one.

1080 x 1350 and 1440 x 1800 pixels are both 4:5. At 300 pixels per inch, an 8 x 10 inch print needs 2400 x 3000 pixels, which is also 4:5.

A 4:5 composition crops easily to square, so it is a practical shape when one image has to serve several channels.

Create an image. Edit it with words. Keep refining.

Check the shape before you post

Ask for the change you want, then check the new version against the 4:5 size your channel uses.
