Understanding Dimensional Weight: How ShipTime Simplifies Shipping Costs


Dimensional weight is a method couriers use to calculate the maximum weight of a package based on its size. This calculation, derived from a mathematical formula, primarily considers the parcel's dimensions. The courier will determine the shipment price based on whichever is greater: the actual physical weight or the dimensional weight of the parcel.


How Dimensional Weight Works:


Application: Dimensional weight typically applies to lighter shipments in larger boxes. Some couriers, such as Canpar, prefer to display the dimensional weight on the label instead of the actual weight.


Automatic Calculation by ShipTime: When you prepare your labels with ShipTime, our system automatically calculates the dimensional weight for you. Simply enter the dimensions and weight accurately, and our system will do the rest.


Manual Calculation Formula

If you prefer to calculate dimensional weight manually, use the following formula:

Length×Width×Height divided by the divisible number.

Why Dimensional Weight Matters

Dimensional weight ensures that shipping costs are fair for both the courier and the customer, especially for large but light packages. By considering the space a package occupies in addition to its weight, couriers can optimize their load capacities.
