Our warehouse staff in Inglewood determines shipping charges by calculating the dimensional weight of the package, and then comparing it to the actual weight. Whichever is greater will determine your shipping costs.

Dimensional weight, also called "dim" weight, applies to air shipments. Dimensional weight is used because the space a package takes on an aircraft may cost more than the package's actual weight. If someone ships a large box of foam that weighs almost nothing but takes up a lot of space on the aircraft, dimensional weight ensures that there is a fair cost associated with that package. Dimensional weight is calculated by using the following formula:

L x W x H (cubic inches) / 194 = Dimensional Weight.

Example: 30" x 24" x 22" = 15,840 / 194 = 82 lbs. (round up to the nearest pound)

All ocean freight is billed in cubic feet.  Our warehouse staff in Gardena determines shipping charges by taking the dimensions of the shipment to calculate the total number of cubic feet.  Cubic feet is calculated by using the following formula:

L x W x H (inches) / 1728 = Cubic Feet.

Example: 48" x 42" x 25" = 50,400 / 1728 = 30 cubic feet. (round up to the nearest cubic foot)
