What is dimensional weight?
Actual weight is the weight of the package when put on a scale. Dimensional weight is based on the size and weight of the package. Large items that have a low actual weight, like pillows and lampshades, will result in a higher dimensional weight.
Dimensional weight is calculated by multiplying the dimensions of an item and dividing by the industry-standard "DIM Factor" of 139:
Dimensional Weight (chargeable pounds) = Length x Width x Height (inches) / 139
Fortunately, MyUS members do not have to worry about complex dimensional weight calculations. MyUS TruePrice™ gives you guaranteed upfront pricing based only on the package weight (excludes oversized and pallet shipments).
Oversized packages, crates and pallets:
Oversized packages are packages or pallets with linear dimensions (total Length + Width + Height) greater than 72 inches (183 cm). Items requiring some types of special packaging (e.g. crates), are not eligible for MyUS TruePrice pricing.
