Canada Post · parcel shipping
Canada Post dimensional weight calculator.
Compare the parcel’s actual weight with its volumetric weight and see which one Canada Post uses for billing.
How the estimate works
Canada Post uses a density factor of 5,000 cm³ per kg (139 in³ per lb) for Priority, Xpresspost, Expedited and most U.S./international services, and 6,000 cm³ per kg (166 in³ per lb) for Regular Parcel. The billable comparison is service-specific and this tool does not quote postage.
