These measurements refer to the inside dimensions of the box.
The Length is the larger dimension of the box's opening.
The Width is the smaller dimension.
The Depth is perpendicular to the opening.
Flute is the wave shapes pressed into corrugated medium. The normal direction of flutes is parallel to the depth of the box, so that they are vertical when the box is stacked for shipment.
Flute C. Most common material, crush resistant, and good stacking strength.
Flute B. Takes up less space, puncture resistance. Uses include canned goods and displays.
Flute A. Used most commonly with Flute C in triple wall board.
Single Wall: Also known as double face. The medium is between two sheets of linerboard.
Double Wall: Three sheets of linerboard with tow mediums in between. Great if you are stacking heavy items. It provides extra padding.
Triple Wall: Four sheets of linerboard with three mediums in between
