FAQ
Instagram Aspect Ratio FAQ
What is the best aspect ratio for Instagram feed posts in 2026?+
The 4:5 portrait ratio (1080 × 1350 pixels) is the gold standard for Instagram feed posts. It takes up the maximum vertical screen space on mobile phones, keeping viewers engaged on your content longer than a standard 1:1 square.
Why does Instagram blur or distort my uploaded photos?+
If you upload an image with an unsupported aspect ratio or higher than 1080px width, Instagram will automatically compress and crop it using their aggressive internal compression algorithm. Pre-formatting your image to exact Instagram specs prevents unexpected distortion.
How does the "Blur Background" feature work?+
Instead of cropping off parts of your photo to fit a vertical or square frame, Blur Background generates an enlarged, soft-focused background from the original image itself while keeping your full subject intact in the center.
What dimensions are used for Instagram Stories and Reels?+
Instagram Stories and Reels use a 9:16 vertical ratio at 1080 × 1920 pixels.
