Carton Size Calculator
Calculate carton volume, total shipment CBM, and air-express volumetric weight from carton dimensions. Use it when a supplier gives carton measurements and you need a quick shipping-size check before asking for a freight quote.
Calculate carton size
Result
Use this result
Check outer carton volume and compare scale weight with a dimensional-weight estimate. Use packed measurements, including inserts and protective material.
Worked example
A 50 × 40 × 30 cm carton occupies 0.06 m³. Fifty cartons occupy 3.00 m³. At 5000 cm³/kg, the dimensional estimate is 12 kg per carton.
Check before using the result
Keep all three dimensions in the selected unit. Carton count is a whole number; actual weight is per carton, not the shipment total.
What this tool does not establish
This page uses a 5000 cm³/kg estimate. For another divisor or mixed carton sizes, use the dedicated shipping-weight or CBM tool. Carrier rounding and surcharges are separate.
Questions about this task
Does this choose a box that fits my product?
No. It evaluates dimensions you provide; it does not design protective packaging or test physical fit.
