Frequently Asked Questions
What are the best image sizes for Instagram in 2025?
The ideal Instagram image sizes are: Square Post 1080x1080px, Portrait Post 1080x1350px (best for engagement), Landscape Post 1080x566px, Story/Reel 1080x1920px, and Profile Picture 320x320px. Portrait posts tend to take up the most feed space and get better engagement.
What aspect ratios does Instagram support?
Instagram supports aspect ratios from 1.91:1 (landscape) to 4:5 (portrait) for feed posts. Stories and Reels use 9:16 (1080x1920px). Square posts use 1:1. The 4:5 portrait ratio is recommended as it takes up the most screen space in the feed.
How can I maintain image quality when resizing for Instagram?
Start with the highest resolution source image possible. Our tool uses high-quality canvas rendering to maintain clarity. Upload images in PNG or JPG format, and always use the recommended dimensions rather than letting Instagram auto-crop your photos.
