Instagram Post Size
The exact pixel sizes for Instagram posts — and a tool to resize yours.
Instagram supports three feed shapes: square (1080×1080), portrait (1080×1350) and landscape (1080×566). Portrait takes up the most screen space, so it tends to perform best.
Resize your photo to any of these here without losing quality to Instagram's compression. It runs in your browser, so your photos are never uploaded.
