Direct Answer
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).

Why You Must Add 2 Inches to Pant Waist
Your belt size is always 2 inches larger than your labeled pant size for two practical reasons:
- Fabric Bulk: The belt fastens on the outside of your trousers, pocket linings, and tucked-in dress shirts.
- Vanity Sizing in Pants: Modern pants labeled 34W often measure 35 to 36 inches around the actual waistband.
