Product width refers to the total number of different product lines a company offers within a specific category. For example, a company that sells shoes may have various lines such as sneakers, boots, and sandals. Each line can include multiple styles, colors, and sizes, but the width focuses on the variety of lines available. A wider product width can help a company appeal to a broader audience by catering to different preferences and needs. However, managing a wide range of products can also increase complexity in inventory and marketing strategies, requiring careful planning and execution.
