FAQ
What is dimensional weight?
Dimensional weight reflects package density. Large, light packages take up cargo space, so carriers charge based on size, not just weight.
Why do carriers use different divisors?
Different carriers and service types (domestic vs international) use different divisors based on their cargo space considerations.
How can I reduce shipping costs?
Use smaller boxes, reduce packaging material, and consider flat-rate options for dense items.
