Formula
Scaled Width = Original Width × (Percent / 100) | Aspect Ratio = Width / Height | Cropped Size = cropWidth × cropHeightPercent = Resize percentage relative to original dimensions (e.g., 50% = half size)
Aspect Ratio = Width-to-height ratio, preserved when Lock Aspect Ratio is enabled
cropWidth/Height = Pixel dimensions of the selected crop region
Worked Example
Resize 1920×1080 image to 50%
