European size 40 typically corresponds to a women's medium or a men's large in clothing. In terms of measurements, it usually translates to a bust size of about 94-96 cm, a waist size of 76-78 cm, and hip size of 102-104 cm. This sizing system is commonly used in countries across Europe, including France, Germany, and Italy. When shopping for shoes, European size 40 generally equates to a women's size 7.5 to 8 in the U.S. or a men's size 6.5 to 7. This size is part of the metric system, which uses centimeters for accurate measurements, making it easier to find the right fit compared to other sizing systems.
