BOX INDUSTRY DEFINITIONS
Test:
This is the test weight of the cardboard used in the construction of the box. It is the
bursting strength in pounds per square inch of the cardboard. This is different than
the weight capacity of the box. In general, a test weight of 200 yields a box with a
weight capacity of 65 pounds. A test weight of 350 yields a box with weight capacity of
100-120 pounds.
Test weight of 200 is approved for standard shipping; unless your item weighs more
than 65 lbs.
Girth plus length:
This is a formula used by shipping companies to determine shipping costs of a box. Out
of the three dimensions of a box the longest dimension is considered to be the length.
The other two dimensions are each doubled and then added together to obtain the girth.
For example, if a box is 24" long,18" wide and 28" tall, according to the formula, the
length is 28"; therefore the girth plus length is as follows:
Length: 28
Girth: 24 + 24 +18 + 18 = 84
Girth plus length is 84 + 28 = 112"
It is in your best interest to contact different Shippers to get their domestic or
