Label size refers to the physical dimensions of a label, typically measured in inches or millimeters. It includes both the length and width of the label. The size of the label is determined based on the surface area it needs to cover on the product or package. It is crucial to choose the right label size as it impacts the visibility and readability of the information printed on it. For instance, a label that is too small may not be easily readable, while a label that is too large may not fit properly on the product or package. The label size also affects the overall design and layout of the label, including the size and placement of text, images, and other elements.
