Instagram has specific image size requirements that can make or break your content's visual quality. Uploading images that don't match these dimensions can result in unwanted cropping, blurry photos, or awkward borders. In this guide, we'll cover every Instagram image size you need to know.
Instagram Post Sizes
Instagram supports three main post orientations. Here are the optimal dimensions for each:
- Square posts: 1080 x 1080 pixels (1:1 aspect ratio)
- Landscape posts: 1080 x 566 pixels (1.91:1 aspect ratio)
- Portrait posts: 1080 x 1350 pixels (4:5 aspect ratio)
The portrait format (1080 x 1350) is ideal for maximizing screen real estate in the Instagram feed, as it takes up more vertical space when users scroll.
Instagram Story Dimensions
Instagram Stories are full-screen vertical experiences. The optimal size is:
- Stories: 1080 x 1920 pixels (9:16 aspect ratio)
This is the same as most smartphone screens, ensuring your content fills the entire display without black bars.
Instagram Reels
Reels use the same dimensions as Stories:
- Reels: 1080 x 1920 pixels (9:16 aspect ratio)
Instagram Profile Picture
Your profile picture displays as a circle on Instagram. The recommended size is:
- Profile picture: 320 x 320 pixels minimum
Instagram crops this to a circle, so keep your main subject centered to avoid important elements being cut off.

How to Resize Images Without Losing Quality
When you resize an image, you want to maintain as much quality as possible. Here are the best practices:
- Start with high-resolution images — The larger your original image, the better your resized result will be.
- Maintain aspect ratio — Use "Fit" mode to keep your image proportions intact.
- Choose the right format — JPEG for photos, PNG for graphics with transparency.
- Set quality to 95%+ — Higher quality settings preserve more detail.
Common Instagram Image Mistakes
- Uploading low-resolution images — Instagram will stretch them, making them blurry
- Ignoring safe zones — Keep important content away from the edges where Instagram might crop
- Wrong aspect ratios — Instagram will auto-crop images that don't match supported ratios
- Over-compressing — Aggressive compression creates artifacts and reduces quality
