How to use this tool
- Choose an image or enter its width and height in pixels.
- Check its aspect ratio against the available presets.
- Review the closest format and possible cropping before publishing.
Before you start
- The tool compares 1:1, 4:5, 1.91:1, and 9:16 presets; it is not a complete list of accepted upload ratios.
- Instagram can change its requirements. Review its current help pages before publishing.
- The tool does not test compression quality, safe areas, or whether an upload will be accepted.
Frequently asked questions
Is the image content analyzed?
No. Only its width, height, and aspect ratio are checked.
Can I upload an image that differs from a preset?
Possibly. A different ratio does not automatically mean an image is unsupported, but it may be cropped or displayed with empty space.
