Essential Image Tips for Instagram
Always upload 1080px wide: Instagram scales down photos wider than 1080px and stretches images narrower than 320px.
Favor 4:5 Portrait: Portrait posts occupy over 80% of a mobile screen, leading to higher thumb-stopping power and engagement than square posts.
Use sRGB Color Space: Save your export files with sRGB color profile to prevent color shifts in mobile browsers.
