Instagram design tips that matter
Knowing the pixel sizes is half the battle. Here's what separates designs that get engagement from designs that don't.
Default to 1080x1350
Portrait posts take up 78% more screen than landscape. Bigger surface area, more engagement.
Carousels must match
All slides in a carousel must use the same aspect ratio. Mix square and portrait and Instagram crops them weirdly.
Center the focal point
When Instagram generates thumbnails for the grid, it crops to square. Keep your subject in the middle 1080x1080 area.
Export at 1080 wide minimum
Anything smaller and Instagram upscales it, which kills sharpness. 1080px wide is the magic number.
