The dimensions given in the title represent an “industry standard” – a basic size that most manufacturers produce and that people in the industry use to easily identify a type of item. However, not all manufacturers produce their products the same way. For example, a title might say 12", but the item may actually be slightly larger or smaller. We include both measurements to help you find the product you’re looking for and so you also know how large the product actually is.
