Frequently asked questions
What does the Box Net Area calculate?
Wrapping overlap and ribbon are separate allowances beyond the geometric box surface area.
Which values should I enter?
Enter Length, Width, Height using the units and format shown beside each field.
What formula does this calculator use?
The calculator uses the following relationship: Surface=2(lw+lh+wh); wrapping=1.2×surface; ribbon=2(l+w)+2(l+h)+30.
Why might my result differ from another source?
Results can differ when another source uses different units, rounding rules, conventions or assumptions. Compare the inputs and definitions before comparing results.
Does the result update automatically?
Yes. Changing an input updates the result using the same calculation engine shown on this page.
