Instagram also recommends 1080 x 1350 px for portrait posts.
Frequently Asked Questions
What is the standard Instagram post size?
The best standard Instagram post size is 1080 x 1080 pixels (a square 1:1 aspect ratio). You can also use 1080 x 1350 pixels for portrait posts.
Should I use a square or portrait format on Instagram?
While square posts are classic, Instagram recommends using portrait images at 1080 x 1350 pixels because they occupy more vertical screen space, making your content more engaging.
Why does Instagram crop my photos?
Instagram automatically crops photos that do not match its supported aspect ratios (1:1 for square or 4:5 for portrait). Pre-resizing your image prevents unexpected cropping.
How is my privacy protected?
The resizing process runs entirely in your web browser. Your images are never uploaded to any server, so your photos remain completely private.
