Vanliga frågor
How do you calculate aspect ratio?
Divide the width and height by their greatest common divisor. For example, 1920 and 1080 share a divisor of 120, so 1920:1080 reduces to 16:9.
How do I resize without changing aspect ratio?
Use one known target dimension and multiply or divide by the ratio. If you know the target width, height equals target width multiplied by original height divided by original width.
What is the CSS aspect-ratio value?
CSS uses a slash form such as aspect-ratio: 16 / 9;. The calculator shows the reduced pair so you can copy it directly into a rule.
Can I use units other than pixels?
Yes. The ratio is unitless, so width and height can be pixels, inches, millimeters or any matching unit. The resize result uses the same unit you typed.
Is this aspect ratio calculator private?
Yes. All calculations run locally in your browser. No image, video or dimension data is uploaded.
