How this tool works
Outputs the four radii in clockwise order: top-left, top-right, bottom-right and bottom-left.
Enter top-left (px), top-right (px), bottom-right (px), bottom-left (px). Update the result, inspect it, then copy or download the output. Reset restores the example inputs so you can start a new calculation.
Example inputs: Top-left (px): 12 · Top-right (px): 12 · Bottom-right (px): 12 · Bottom-left (px): 12.
