Purolator Dimensional Weight Calculator

Purolator has established itself as Canada's leading courier company, with the most extensive network within Canada and strong cross-border capabilities to the United States. For Canadian businesses and individuals shipping domestically or to the US, understanding Purolator's volumetric weight system is essential for accurate cost planning and effective budget management. Purolator applies standard volumetric calculations to most shipments, comparing dimensional weight against actual weight and charging the higher value to determine final pricing. The company offers various service levels including Express, Ground, and Freight, each designed for different speed and cost requirements to suit various shipping needs. For e-commerce sellers and businesses shipping within Canada, Purolator's extensive domestic network provides reliable coverage including rural and remote areas that other carriers may not serve as effectively. Their strong US cross-border service makes them a go-to choice for Canadian businesses selling into the American market. Understanding their pricing mechanics helps optimize shipping strategies and manage logistics costs effectively.

Purolator calculates volumetric weight using length × width × height (cm) ÷ 5000 = volumetric weight in kg. For imperial measurements, the divisor is 139 cubic inches per pound. Purolator measures packages at their longest points in each dimension. The calculated volumetric weight is compared to actual scale weight, and the higher value becomes the billable weight. Purolator's online tools provide shipping estimates based on dimensions and weight inputs before shipping.

Purolator determines billable weight as the greater of actual or volumetric weight. This approach is consistent across their express and ground services. For lightweight but bulky items, volumetric weight typically exceeds actual weight, increasing shipping costs. For dense, heavy items, actual weight usually determines the rate. Purolator's pricing also factors in origin, destination, and service level, making both weight and routing important for cost estimates.

A common mistake is not accounting for volumetric weight when shipping lightweight items in larger boxes—this significantly increases costs. Shippers sometimes don't compare Purolator's service levels to find the right balance of speed and cost. Another pitfall is not using Purolator's business tools and contract rates, which offer significant savings over published rates. Some shippers underestimate Purolator's capabilities for remote Canadian delivery, choosing alternatives that are actually slower or more expensive.
