Owning the Instagram Feed

If you upload a horizontal landscape photo to Instagram, it barely takes up any vertical space on a user's phone, making it easy to scroll past. To maximize your engagement, you must format your images to take up the entire screen. The optimal size for an Instagram post is a portrait dimension of 1080 x 1350 pixels (a 4:5 aspect ratio). This size commands attention, increases dwell time, and is the undisputed standard for influencers and brands.

Frequently Asked Questions

What is the best image size for an Instagram post?
The best size is 1080 pixels wide by 1350 pixels tall (portrait). A 1080 x 1080 pixel square is the second best option.
Will Instagram crop my 1080x1350 photo?
In the main feed, it will show the full tall photo. However, on your profile grid, Instagram will center-crop it to a perfect square. Ensure the focal point of your photo is near the center.
Why does my photo look blurry on Instagram?
Instagram heavily compresses images that are over 1080 pixels wide. By resizing your photo to exactly 1080px wide using our tool, you prevent Instagram's algorithm from ruining your quality.
Can I upload a 4K photo to Instagram?
You can, but Instagram will forcibly downsize it to 1080px, often resulting in quality loss. It is much better to resize it to 1080px yourself first.
Does this tool work for Instagram Carousels?
Yes! To make a seamless carousel, ensure every single slide is resized to the exact same dimension (e.g., all 1080x1080) before uploading them together.
Can I add white borders to a landscape photo here?
Our tool focuses on cropping and dimension resizing. To fit a wide photo into a square without cropping it, you would need a 'padding' or border tool.
Is my privacy protected?
Absolutely. Your personal photos are resized directly on your smartphone or computer's processor. They are never uploaded to a cloud database.
