An International Size Chart is a standardized guide that helps consumers understand clothing sizes across different countries. Since sizing can vary significantly from one region to another, this chart provides a reference for converting sizes, ensuring that shoppers can find the right fit regardless of where the clothing is made. Typically, the chart includes measurements for various categories, such as men's, women's, and children's clothing. It often lists sizes in terms of US, UK, EU, and JP standards, making it easier for individuals to compare and select appropriate sizes when shopping internationally.
