What resolution should the profile cover on Habr Freelance have?

Question

Habr

I registered on Habr freelancing , I fill out a profile and the first thing that catches my eye is the cover and ava. It’s clear with the avatar, the aspect ratio is 1 to 1, but it’s not clear with the cover. The clue says

Format: jpg, gif, png.
Maximum size: 2Mb, 2000px

Is 2000px width or height? What is the aspect ratio anyway? I would like to make the cover beautiful, and not something pixelated in low resolution.

What resolution should the profile cover on Habr Freelance have?
VK has a cover for a group, for example, 1590 x 400 px.

Answer 1

750x220
