How many inches is a women's size 3 waist?

According to sizing standards in the United States, a women's size 3 waist tends to be about 24 1/2 inches in circumference. Some manufacturers do make clothing in this size that can fit up to a 26 inch waist.

It should be noted that not all clothing manufacturers strictly follow the same sizing guidelines, which is why many brands offer custom sizing guides to their customers in order to ensure a perfect fit. Certain variables, like torso size, length, hip width and leg size can also have an effect on sizing, making it essential that a woman measures her waist and follows the sizing guideline to ensure a perfect fit.
