Tips & best practices
- Use 1080x1350 (4:5 portrait) for feed posts — it takes up more screen real estate and gets higher engagement
- Stories and Reels require 1080x1920 (9:16) for full-screen display
- Instagram compresses images heavily — start with the highest quality source image possible
- Profile photos display at 110x110px on mobile but upload at 320x320px for sharpness on retina displays
- Carousel posts perform best when all slides are the same aspect ratio
Frequently Asked Questions
What is the best image size for Instagram posts in 2026?
1080x1350 pixels (4:5 portrait ratio) is the recommended size for Instagram feed posts in 2026. This ratio maximizes the space your post takes up in the feed, leading to higher engagement. Square posts (1080x1080) are also well-supported.
Will Instagram crop my image if it's the wrong size?
Yes. Instagram auto-crops images that don't fit supported aspect ratios (1:1, 4:5, or 1.91:1). Resizing to the correct dimensions before uploading ensures your image appears exactly as intended with no unwanted cropping.
What resolution should Instagram Reels be?
1080x1920 pixels (9:16 aspect ratio). This is the full-screen vertical format used by Reels and Stories. Using lower resolution will result in visible pixelation on high-DPI phone screens.
Does this tool compress my image quality?
The resize tool maintains maximum quality during the dimension change. You can also use our image compressor separately if you need to reduce file size after resizing.
