Box dimensions are always inside dimensions and
must be stated in milimeters/inches, in the sequence of:
1. Length
2. Width
3. Depth
The length is the LARGER of the two
dimensions of the open face (flap opening); while the SMALLER
of the dimension measurements is the width.
The depth is always the distance measured
perpendicular to the length and width between the innermost surfaces of
the box.
Pads, liners, partition pieces, die-cut pads,
scored blanks and sheets of corrugated or solid fibre board, with only
two dimensions, have their size specified with the first dimension
parallel to the corrugations, or perpendicular to the grain of solid
fibre board.
