About This Tool
How to find your belt size: it is not the same as your pants size. A properly fitting men's belt fastens at the middle hole with no extra tail. This belt size calculator converts your pants size or waist measurement into the correct belt size for any fit preference. Building a wardrobe? Our Capsule Wardrobe Builder includes belt recommendations that match your style.
How to Use
Choose to calculate from your pants size or a waist measurement. If measuring, wrap a tape around your waist over a tucked-in shirt where you wear your belt. Select your fit preference and get the exact size to buy. Need to size other accessories? Try our Dress Shirt Size Calculator or Suit Size Estimator.
FAQ
Why is my belt size different from my pants size?
Your belt goes around the waistband, which adds material thickness. The standard rule: belt size equals pants size plus 2 inches. Size 34 pants need a size 36 belt. This accounts for fabric, belt loops, and a tucked shirt. The rule works for about 90% of men. For dress outfits, our Suit Size Estimator helps you match trouser and belt sizing.
Does leather stretch over time?
Yes. Full-grain leather stretches 0.5-1 inch over the first few months, while bonded leather stretches more and loses structure. Buy so it fits at the middle hole when new, then move tighter as it breaks in. Synthetic belts do not stretch and may crack instead.
When should I size up instead of using the standard rule?
Size up if you wear pants higher on your waist, plan to pair the belt with heavier fabrics like denim or wool, or carry extra weight around the midsection. Also size up if you are between two even numbers. It is always easier to punch an extra hole than to stretch a tight belt. Our Shoe Size Converter takes a similar better-safe-than-sorry approach.
