How to Measure Belt Size For the Perfect Fit: A Practical Guide

If you ever asked yourself - what belt size am I? - you are not alone. Belts are an important accessory for any outfit, but finding a well-fitting belt can be a challenge. The wrong size leather belt can make your outfit look sloppy or create an uncomfortable experience all day long. The best way to get the perfect fit is to measure yourself before making your purchase. In this blog post, we'll take you through how to measure for a new leather belt - from start to finish - so that you don't have any surprises when your new tailor-made belt arrives in the mail.

TLDR: Always measure yourself to get the best fitting belt. Buy belts that you fit in the middle of. Pants size ≠ belt size. Sometimes, belt size = pants size +2 inches, but the best way to get the right size belt to measure your waist.

NO, your pant size is NOT your belt size.

The most common mistake people make when shopping for a new belt is assuming their belt size is the same as the number or letter size of their existing belt or pant size. This usually isn't the case because the materials modern clothes are made with tend to stretch and deform with use, and clothing manufacturers often use vanity sizing in pants size.

What size belt should I get?

The general rule of thumb for belt sizing is your men's pant size plus two inches equals your belt size.

Belt Size = Men's Pant Size + 2 inches

Simply add 2 to your pant size to get your belt size. If your pants size is 32, buy a belt size 34. If your pants size is a 34, buy a belt size 36; if your pants size is a 36, buy a belt size 38, etc. The reason you buy a belt size up from your pants size is to give yourself a few inches of room in case your body size ever changes.

The simple formula works well enough, but due to the vast difference in sizing between clothing brands, we no longer recommend using it as the best way to find the correct size belt. The best method to choose a belt size is to always measure yourself before purchasing a new belt. And remember: new leather belts tend to fit snug initially, then warm and mold to your body with use. The optimal belt size fits comfortably on the center hole, with additional holes in case your waist size changes.

How to determine belt size with a tape measure


  • Cloth measuring tape
  • The outfit you want to use your belt with (jeans, trousers, dress, etc.)
  • Mirror (optional)

Step 1: Put on the outfit you want to wear with your new belt. Pull your pants up to the height you typically wear them and tuck in your shirt if that is what you usually do.

Step 2: Weave the cloth tape measure through the belt loops of your pants as shown in the example. If you want a hip or waist belt, measure at your natural waistline or at the height you would typically wear the belt.

Our belts can be worn in many ways with jeans, dresses, kilts, etc. Measure where you want to wear your belt. For example, if you wear it at your natural waistline, measure there. If you wear it on your hips, measure through the belt loops of a pair of pants.

Step 3: Pull the tape measure snug, but not uncomfortably so. Take note of your measurement to the nearest quarter inch. It is important to get the correct measurement, so use a mirror or a friend to help if you need to.

Step 4: Consult the belt size chart.

The belt sizes listed give a range of tightest to loosest that it can be worn. Choose the belt size closest to your actual waist size. Your measurement should fall in the middle of the range. For example, if you measured your waist as 37.25 inches, buy a size 36 belt.

How to order a custom belt size

If you can't find your size in our size charts or are just looking for a super perfect fit, we can make you a custom size. Be sure to measure to the nearest quarter inch, not the nearest inch. The more precise you are in your waist measurement, the better the fit will be.

Step 1: Measure your body as described above.

Select Custom Size then type your waist measurements in. Every custom belt has 6 inches of size adjustment.

Step 2: Select CUSTOM SIZE from the size options for one of our handmade leather belts. Write your waist measurement to the nearest quarter inch in the section provided. Write something like: "I measured myself and my measurement is 37.25 inches." We will make a belt size based on your exact measurements, with a few holes bigger and smaller so you can continue to use your belt if your body changes.

Can I just measure my current belt?

It is possible to find your belt size based on your current belt, but it is less accurate than other methods. Belts can be made of many different types of leather, and not all belts are made with the high quality full grain leather we use. Cheap leather belts tend to stretch over time, like braided belts and belts made with cheaper materials. They are prone to stretching and distortion over time, so don't measure these types of belts to find your optimal belt size.

How to determine belt size from current belt

Here's how to find your belt size if you already own one of our cool belt buckles and thick leather belts. This method works best when giving a belt as a gift, but will also work to measure a belt with a traditional belt buckle or ranger belts.


  • Soft tape measure or metal measuring tape
  • Flat surface
  • Your current belt

Step 1: Lay your leather belt out on a flat surface.

Step 2: Use the tape measure to get the belt length from the belt hole you typically use to the center of the hole in your Obscure Belt buckle. For leather belts with a traditional buckle, measure the belt length from your usual belt hole to where the prong touches the frame of the buckle.

The example below shows you exactly where to measure from on an Obscure Belts buckle or a traditional belt type with your measuring tape. Always measure to the nearest quarter inch, measuring to the nearest inch is not precise enough.

Step 3: Consult our belt sizing charts. Choose the size from the belt sizes shown that your measurement is in the middle of. Our goal is to make you a belt that fits snug initially at the middle hole and that gives you flexibility if your body changes.
