Comparing:
Belt Sizes
Hat Sizes
Standard leather belt sizing defines the exact linear measurement from the inside fold of the buckle to the middle center adjustment hole (the 3rd of 5 holes). Sized in 2-inch increments, the universal rule dictates choosing a belt 2 inches larger than trouser waist size (e.g., 34W pant takes a Size 36 belt).
Hat and cap sizes are derived directly from head circumference measured one centimeter above the ears. Sized in traditional fitted fractions (6-1/2 to 8-1/4) and alpha sizes (S to 3XL), the US numerical size represents head diameter in inches calculated by dividing circumference in centimeters by 8.
