Formula
What the calculator does
Box volume equals length × width × height. Cubic feet divide cubic inches by 1,728, and liters use the exact inch-to-metre conversion. The largest face is the greatest of length × width, length × height, and width × height.
Keep the result honest
- Measure the finished outside box at its extreme points.
- Compare a label’s exact width and height—not just its area—with the selected face.
- Check the supplier’s specifications for material, contents, printing, and use.
