What is an Aspect Ratio Calculator?
An aspect ratio calculator is a tool that helps you determine the dimensions of an image or video based on a specific ratio (like 16:9 for widescreen video or 4:5 for social media). You can lock either the width or the height and adjust the other dimension, and the calculator will automatically calculate the corresponding value to maintain the chosen aspect ratio. It's essential for designers, video editors, and anyone working with digital media.
How to Use This Tool
- Set Dimensions: Enter a width or a height in pixels. The other dimension will update automatically based on the selected aspect ratio.
- Choose an Aspect Ratio: You can manually type in a ratio (e.g., 16 and 9) or select one of the common presets like "16:9," "4:3," or "1:1" (square).
- Swap Dimensions: Use the swap button to quickly switch between landscape and portrait orientations.
- See the Preview: The live preview on the right visualizes your chosen aspect ratio and displays the calculated pixel dimensions.
- Copy Results: Click the "Copy Dimensions" button to easily copy the "width x height" values to your clipboard.
