What is Aspect Ratio?
Aspect ratio is the proportional relationship between an image’s width and height (e.g. 16:9, 4:3, 1:1). It describes the image’s shape.
Exact Ratio vs Common Ratio
The exact ratio shows the precise width-to-height relationship, while the closest common ratio rounds it to a standard format like 16:9, 4:3, or 1:1.
Why Ratio Matters
The right aspect ratio ensures your images look perfect across websites, social media, video platforms, and print without being cropped or distorted.
Ratio for Social & Video Formats
Different platforms have recommended ratios, like 1:1 for Instagram, 16:9 for YouTube, and 9:16 for TikTok. Our tool helps you find the best fit for any use case.

FAQ & SUPPORT
Frequently Asked Questions
Find quick answers to common questions about image aspect ratios, image details, DPI,
print size calculations, and how our tool works.
No. Your images are analyzed directly in your browser using modern web technology. Nothing is uploaded to our servers, so your files stay private and secure.
We divide an image’s width and height by their greatest common divisor to simplify the ratio. For example, 1920 × 1080 becomes 16:9. The decimal ratio is width divided by height.
The exact ratio is the simplified width-to-height ratio of your image. The closest common ratio is the standard ratio with the smallest decimal difference, such as 16:9 or 4:3. It does not replace your exact ratio.
Yes! Our tool works with supported image formats and is perfect for social media images. It helps you find the exact dimensions and aspect ratios for platforms like Instagram, Facebook, YouTube, Twitter, and more.
Some images may show unusual ratios because they were cropped, resized, or edited. Not all images use standard ratios like 16:9 or 4:3.
