Notes on Shipment Dimensions
Declaring accurate weights and dimensions while creating your shipments gives you access to the best pricing for your shipment. The tables below outline the maximum weight and dimensions for each of our services, organized by destination. If your shipment exceeds the limit for a particular service, you will not be able to receive a postage rate for that service.
We recommend following these guidelines for how to accurately measure your shipments for a smooth shipping experience.
Additionally, it is not well known but the dimensions of your shipment can also cause issues with generating postage like when a shipment’s dimensional weight exceeds a service’s weight limit. To learn more about dimensional weight please, visit our helpful support article.
