The dimensions we require to produce your box are the internal dimensions. These should be stated as;
Length (largest side of opening) x Width (shortest side of opening) x Height (depth of carton).

When specifying a carton we also need to know the approximate weight of the product going into the carton and also if the cartons are to be stacked, if stacked how high. This will allow our designers to select a suitable material for your carton.
