How to use this tool
Measure your product in centimetres and add a clearance allowance on each side. The calculator adds this amount twice to each dimension to estimate internal box size.
Volume is calculated as length × width × height. Indicative volumetric weight divides cubic centimetres by the divisor you provide.
Box measurements shown are internal dimensions. Cardboard thickness and folding change external dimensions. Couriers may use outside measurements and other divisors.
Frequently asked questions
Will it calculate a shipping price?
No. Shipping price can depend on destination, actual weight, volumetric weight and service level.
Is this a box dieline generator?
No. It is a dimensional estimate only.
