Size is important for obvious reasons when trying to fit your product in an export carton. Let’s take a quick look on how to properly read and write measurements according to the industry standard.
There are three dimensions to the basic foldi ng carton; Length (L), width (W), and height (H). In written form the dimensions should appear in that order (L x W x H). Use the figure of a reverse tuck carton to the right; match each of the dimensions up with its corresponding side.
When determining the size of a folding carton, be sure to measure from the middle of the score. To ensure accuracy, measurements should be taken to 1/16th of an inch (1.6mm).
Always remember that the height is the vertical dimension of the box when the opening is facing upwards!You can always apply the same principle for other type of similar packing just like in the following pictures.
