Calculate pixel dimensions from aspect ratios with precision
Enter the pixel value for the longest side of your desired dimensions. The calculator will automatically determine which side (width or height) should be the longest based on your selected aspect ratio and calculate the shorter side accordingly.
Example: If you enter 1920px and select 16:9, you'll get 1920×1080 (landscape) or 1080×1920 (portrait) depending on the ratio orientation.
Enter your own custom aspect ratio using width and height values. You can use whole numbers or decimals.
Examples:
The calculator will use these values along with your longest side input to determine the final pixel dimensions.
When enabled, this option rounds both width and height to the nearest numbers divisible by 16. This is useful for:
Note: The aspect ratio may be slightly adjusted to accommodate the divisibility requirement.
