FAQ
Dimensional weight questions
What is dimensional weight?
Dimensional (DIM) weight estimates the space a shipment occupies relative to its actual weight, used to price light, bulky freight fairly.
How is dimensional weight calculated?
Multiply length × width × height in inches, then divide by a standard divisor (139 for many LTL/parcel calculations) to get dimensional weight in pounds.
Which weight do carriers bill?
Carriers bill the greater of actual weight and dimensional weight — the 'billable weight.'
Does the divisor ever change?
Yes, divisors vary by carrier and service (e.g., 139 vs 166). Confirm the exact divisor with your carrier before booking.
