What is Dimensional Weight?

Dimensional weight (also called volumetric weight) is a pricing technique used by shipping carriers to account for packages that take up a lot of space relative to their actual weight. It's calculated using the DIM factor, which is typically 166 for most carriers.

Why Does Dim Weight Matter?

Shipping companies charge based on whichever is greater: the actual weight or the dimensional weight. Large, lightweight packages take up valuable truck space, so carriers use dimensional weight to ensure fair pricing.

Tips for Reducing Shipping Costs

  • Use appropriately sized packaging to reduce dimensional weight
  • Consolidate multiple items into fewer packages when possible
  • Choose packaging materials that are protective but lightweight
  • Remove excess air and void fill from packages
  • Compare dim weight across different carriers

Frequently Asked Questions

How is dimensional weight calculated?
Dimensional weight is calculated by multiplying length × width × height and dividing by 166 (the DIM factor used by most carriers).
What does 'billable weight' mean?
Billable weight is the greater of the two: the actual weight of your package or the calculated dimensional weight. This is what carriers charge you for.
Can I avoid dimensional weight charges?
While you can't eliminate dimensional weight, you can minimize it by using appropriately sized boxes and removing excess air from your package.
Do all carriers use the same DIM factor?
Most major carriers (UPS, FedEx, DHL) use 166 as the DIM factor, but some may use different values. Check with your specific carrier for their DIM factor.
