Frequently Asked Questions

What is the best aspect ratio for Instagram posts in 2025?

The 4:5 portrait aspect ratio (1080 x 1350 pixels) is currently the best performing for Instagram feed posts. This format takes up more space in users' feeds and typically receives higher engagement rates compared to square or landscape posts.

Can I use different aspect ratios in Instagram carousel posts?

No, all images in an Instagram carousel post must use the same aspect ratio. Instagram will crop all subsequent images to match the aspect ratio of the first image in your carousel, so plan accordingly and use consistent sizing.

What happens if I upload an image that doesn't match Instagram's supported aspect ratios?

Instagram will automatically crop your image to fit the closest supported aspect ratio, which may cut off important parts of your image. Always design within supported ratios (1:1, 4:5, or 1.91:1 for feed posts) to maintain full control over your visual content.

Why do my Instagram images look blurry or pixelated?

Blurry images are usually caused by uploading content with resolution below Instagram's minimum requirements. Always use images with at least 1080 pixels width and ensure your file size doesn't exceed 30MB for optimal quality.

What's the difference between Instagram post sizes and Story sizes?

Instagram feed posts support multiple aspect ratios (1:1, 4:5, 1.91:1) while Stories use a fixed 9:16 vertical format (1080 x 1920 pixels). Stories are designed for full-screen mobile viewing, while feed posts appear in a scrollable timeline.

Do I need different image sizes for Instagram ads compared to organic posts?

Instagram ads use the same image size requirements as organic posts. Feed ads support 1:1, 4:5, and 1.91:1 aspect ratios, while Stories ads use the 9:16 format. The technical specifications remain the same regardless of whether content is organic or paid.

How important is the Instagram safe zone for Stories?

The safe zone is crucial for Stories content. Keep important text, logos, and call-to-action elements within 1080 x 1680 pixels (leaving 120 pixels at top and bottom) to prevent them from being covered by Instagram's interface elements like profile pictures and action buttons.

Can I change Instagram image sizes after posting?

No, you cannot change image sizes or aspect ratios after posting to Instagram. The platform doesn't offer editing features for published content. You would need to delete the original post and upload a new one with the correct dimensions if changes are necessary.
