How to Measure Your Jacket Size (Step by Step)

The best way to find your correct size is to follow our size chart and measurement guide. This makes online shopping easier and reduces the chance of returns or exchanges due to incorrect sizing. On this page, you will find a size chart image below, and each American Suiting product page also includes a size chart so you can order based on your exact measurements. If you are still unsure, our video tutorials show how to measure your chest and waist correctly for a clean, comfortable fit.

To measure your jacket size, start with your chest. Wrap the tape under your arms around the widest part of your chest. Keep the tape snug but not tight, and make sure it stays level around your body. Next, measure your waist at your natural waistline. For coats, match both chest and waist measurements to the size chart for the best balance. If you prefer extra room or plan to wear layers, choosing one size up can feel more comfortable. If a perfect fit matters to you, we also offer custom tailoring for a more personal sizing experience.

How to Measure Suit Size (Step by Step)

A great suit fit starts with the right measurements. Use a soft measuring tape and measure over light clothing. First, measure your chest at the fullest part, keeping the tape straight and comfortable. Then measure your waist at your natural waistline while standing relaxed. Once you have these measurements, compare them with the size chart image below to select the best size.

At American Suiting, we focus on tailoring that looks sharp and feels right. Measuring correctly helps your wool suit, blazer, or tailored piece sit properly at the shoulders, chest, and waist, so you can wear it with confidence and precision.
