Measure after packing
Include packaging bulges and use the longest outside measurement on each side.
THE PARCEL PLANNING WORKBENCH
Less guesswork.Better box choices.
See the weight behind the dimensions. Calculate dimensional weight, compare boxes, and check a batch before you ship.

DIM & rounding rules
Example
5000 cm³/kg and 139 in³/lb are examples only. They are different rules, not equivalent unit conversions or carrier quotes.
Follow the calculation
- 01Measure the outside
40 × 30 × 20 cm = 24,000 cm³
- 02Volume ÷ DIM divisor
24,000 cm³ ÷ 5,000 cm³/kg = 4.8 kg
- 03Choose the higher weight
max(2.4, 4.8) = 4.8 kg
- 04Apply weight rounding
No rounding applied → 4.8 kg
EVERY CENTIMETRE COUNTS
Small measurements.Real differences.
An oversized box can carry a bigger dimensional weight even when the contents are light. Begin with the outside dimensions of the packed parcel.
Use your service rules
Set the divisor and rounding to match your current contract and destination.
Compare before shipping
Use the result to plan packaging, then ask your carrier for the actual price.
THE TOOLKIT
A little more clarity, at every step.
Are 5000 and 139 carrier prices?
No. They are sample dimensional divisors with different units. They do not represent a carrier offer, universal rule, or the same physical divisor. Enter the rule that applies to your shipment.
Does switching units change the parcel?
The size and actual weight are converted using 1 inch = 2.54 cm and 1 pound = 0.45359237 kg. The DIM divisor and its unit remain unchanged. Dimension rounding applies in the currently selected input unit; review rounding after switching.
Is this the final shipping charge?
No. Prices can depend on service, destination, contract, minimum weight, size thresholds and surcharges. This tool calculates only the weight under the rules you choose.
Are my CSV files uploaded?
No. CSV parsing and all calculations run in your browser. Refreshing the page clears your current inputs.
