What is Cubic Shipping?

The United States Postal Service (USPS) offers significantly discounted rates for packages that meet specific cubic dimension requirements, regardless of their weight (up to 20Lbs)*. This means that customers will pay shipping costs for the actual size of the package and the shipping distance, instead of its weight. However, many customers find meeting these requirements difficult and confusing. So, we have partnered with USPS and have designed specialized Chit Chats Express USPS Priority boxes that conform to their specific cubic shipping dimensions requirements. Taking the guesswork out of cubic shipping!

For example, if you were to ship a camera (approx. 4 lbs) to Los Angeles CA using regular USPS shipping, it would cost $15.76 USD, but if you used one of our Chit Chats Express cubic shipping boxes, it would cost you only $7.09 USD… That’s over a 50% savings!!

How does Cubic Shipping work?

Cubic pricing for a rectangular package is determined by measuring Length x Width x Height / 1728 to calculate the Cubic Fee. (Note: All measurements are rounded to the nearest 0.25 inch).  For example, if you had a package that measured 6” x 5” X 4” it would fall within the A box type.
