Formula and methodology
Formula: scale = min(boxW/srcW, boxH/srcH); fitW = srcW x scale; fitH = srcH x scale.
The smaller ratio binds so the image fits without cropping. Full-precision values carry display precision 2.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
