Parcel size and dimensional-weight calculator

Calculate parcel volume, girth, and optional dimensional weight from your measurements.

A measurement aid, not a shipping quote or a carrier acceptance check. Measure the outside of the packed parcel. The tool treats the longest side as length.

If entering a divisor, confirm that it matches your length units and selected result weight unit. No divisor is assumed. Carrier rounding and billing rules are not applied.

What these measurements mean

Volume = length × width × height. Rectangular girth = 2 × width + 2 × height. Length plus girth adds the longest side. Optional dimensional weight = volume ÷ your entered divisor. The tool reorders the sides if needed.
