Frequently Asked Questions
Common questions about Ratio Calculator and image optimization
What is an aspect ratio calculator?
An aspect ratio calculator is a tool that helps you calculate the proportional relationship between the width and height of an image or video. It's essential for ensuring your content displays correctly across different platforms and devices.
What are the most common social media aspect ratios?
The most common social media aspect ratios are: Instagram Story (9:16), Instagram Post (1:1), TikTok (9:16), YouTube Thumbnail (16:9), Facebook Post (1.91:1), and Twitter Post (16:9).
How do I calculate aspect ratio?
To calculate aspect ratio, divide the width by the height. For example, if your image is 1920×1080 pixels, the aspect ratio is 1920÷1080 = 16:9. You can use our calculator to automatically compute this for any dimensions.
What size should I use for Instagram Stories?
Instagram Stories should be 1080×1920 pixels with a 9:16 aspect ratio. This ensures your content displays perfectly on mobile devices and maintains quality across all Instagram users.
How do I resize an image without distortion?
To resize without distortion, maintain the same aspect ratio. Use our calculator to find the new dimensions, or crop your image to fit the desired aspect ratio. Always work with the original high-resolution image when possible.
What's the difference between aspect ratio and resolution?
Aspect ratio is the proportional relationship between width and height (like 16:9), while resolution is the actual pixel dimensions (like 1920×1080). You can have the same aspect ratio at different resolutions.
