A size chart is a tool used to help individuals determine the appropriate size of clothing or footwear. It typically includes measurements for various sizes, such as small, medium, large, and extra-large, along with corresponding body measurements like chest, waist, and hip sizes. Size charts can vary between brands, so it's important to refer to the specific chart for the item being purchased. Using a size chart can enhance the shopping experience by reducing the likelihood of ordering the wrong size. Many online retailers provide size charts on their websites, often alongside product descriptions. This ensures that customers can make informed decisions when selecting items from brands like Nike or Adidas.
