Pay attention to the cut of the brief and the material when choosing a style and a size.

    Familiarise yourself with the size options available. Small size fits waist measurements from 28 to 30 inches. Medium waist size is 32 to 34 inches. Large fits a 36 to 38-inch waist, followed by XL, which fits a 40 to a 42-inch waist. For larger waist sizes, choose XXL.

    Compare the waist size of your trousers to the waist size options on the back of the package of boxer briefs.

  5. 5

    Choose a size that best matches your waist size.

    Select the next size up if your waist measurement falls in between two of the choices. For example, if your waist is 31 inches, select medium-sized boxer briefs.
