About This Calculator
The Jacket Size Calculator helps you find your perfect coat size by matching your body measurements against standard US and EU sizing charts. Whether you are shopping for a casual blazer, a formal suit jacket, or a winter coat, knowing your accurate jacket size ensures a comfortable and flattering fit. This calculator is designed for both men and women and covers the full range from XXXS to 6XL.
How It Works
For men, the calculator uses your chest width and height measurements to determine your jacket size. For women, it uses chest and hip measurements. Each measurement is compared against published sizing standards derived from apparel industry guidelines to find the best match. The chest measurement is the primary determinant — your height or hips act as a secondary check to refine the result.
How to Measure Correctly
For accurate results, use a flexible measuring tape and take measurements close to your body over lightweight clothing or bare skin. Chest: Wrap the tape under your armpits at the fullest part of your chest, keeping it parallel to the floor. For women, measure at the widest part of the bust. Height: Stand against a wall and measure from the top of your head to the floor. Hips: Wrap the tape around the widest part of your buttocks with feet together. Do not pull the tape too tight — leave about one inch of space for comfort.
Regional Sizing Notes
This calculator supports both US letter sizing (XS–6XL) and EU numeric sizing (40–72). US sizes are more common in North America, while EU numeric sizes are standard across Europe, Asia, and many online retailers. If you are shopping internationally, use the EU size column as your reference. Brands may vary slightly from these standards, so always verify against the specific brand's size chart when possible.
Frequently Asked Questions
How do I measure my chest for a jacket?
Wrap a measuring tape under your armpits at the fullest part of your chest. Stand up straight and relax — do not puff out your chest. Leave about an inch (2.5 cm) of space for movement. For women, measure at the widest part of your bust.
What is the difference between US and EU jacket sizes?
US jacket sizes use letter-based sizing (XS, S, M, L, XL, XXL) which corresponds to chest measurement ranges in inches. EU jacket sizes use numeric sizing (44, 46, 48, 50, etc.) which corresponds to chest measurement ranges in centimeters. For example, a US size M typically corresponds to EU size 48 with a chest range of 38-40 inches.
What jacket size should a 5'11" man wear?
A 5'11" (180 cm) man typically wears an XL US jacket size (EU 54 or 56), provided his chest measurement falls between 44-45 inches (106-113 cm). If his chest is larger than 45 inches, he should size up for a comfortable fit, as chest is the primary determinant of jacket size.
What size does M correspond to for women's jackets?
A women's jacket size M corresponds to EU size 38 and typically fits a chest measurement of 33-34 inches (86-89 cm) with hips of 37-38 inches (96-98 cm). These measurements can vary between brands, so always check the specific brand size chart.
How do I measure hips for a women's jacket?
To measure your hips for jacket sizing, wrap a measuring tape around the widest part of your buttocks. Keep your feet together while measuring for maximum accuracy. This measurement is used alongside chest measurement to determine the correct women's jacket size.
What if my measurements fall between two jacket sizes?
If your measurements fall between two sizes, choose the larger size for a more comfortable fit. Jackets can always be tailored slightly smaller, but a too-small jacket cannot be enlarged. Consider the jacket's fabric — stretch materials may allow a closer fit, while non-stretch fabrics require more room.
What is a 42 jacket size in US men's sizing?
A size 42 EU men's jacket corresponds to US size XXS, fitting a chest of 32-34 inches (82-85 cm) and a height of 64-65 inches (162-166 cm). This is an uncommon size for adult men and is typically found in specialty or children's sizing.
How are jacket sizes labeled in the US vs Europe?
US jacket sizes use letter labels such as XS, S, M, L, XL, XXL, 3XL, 4XL, 5XL, and 6XL based on chest measurement in inches. EU jacket sizes use numbers from 40 to 72 based on chest measurement in centimeters. The conversion is roughly: US XS = EU 44, US S = EU 46, US M = EU 48, US L = EU 50-52, US XL = EU 54-56, US XXL = EU 58-60.
