Simply stated, what are you putting into this box? How much internal packing is needed to protect your product? When we systematically combine that information, we will pin-point the most economical size & style of custom corrugated box to suit your needs.
There are three dimensions to all boxes, Length, Width, and Depth. Our industry uses the inside dimensions for measuring purposes. If you are measuring an existing box, set it on a table so that it is open at the top. Measure the inside size of the opening. The longer dimension is the length, and comes first in order.
The other dimension is the width. Now, measure the distance from one of the inside corners to the top. This is the depth. When you tell us the dimensions of the box, they need to be in this order, Length x Width x Depth.
