How to Measure Suit Size
How to Measure Yourself for a Suit
Suit Size Estimator
Fit is one of the most important factors when choosing a suit. Use the Suits Outlets size estimator below as a reference for regular, big and tall, and short sizing across 2-piece suits, 3-piece suits, double-breasted suits, pinstripe suits, and other styles. Mandarin collar and slim-fit styles may fit slightly smaller. Contact our Style Advisor if you need help choosing a size.
Tuxedo Size Estimator
Tuxedo sizing generally follows the same chest-and-length system used for suits. Use the estimator below to find a starting size for weddings, formal events, church groups, theater productions, and other special occasions. If you are unsure about fit or ordering for a group, contact us for assistance.
Outerwear Size Estimator
A common mistake is automatically choosing a larger size for a coat. Most tailored outerwear is designed with enough room for the clothing worn underneath, so your usual jacket size is often the best starting point. Use the estimator below as a reference, and contact us if you need help with fit.
Jacket Size Estimator
A well-fitting sport coat or blazer should sit comfortably through the shoulders and chest without pulling or excess fabric. Use your chest measurement and height as a starting point, then consider the cut of the garment. A general letter-size reference is: XS (32-34), Small (34-36), Medium (38-40), Large (42-44), XL (46-48), 2X (50-52), 3X (52-54), 4X (54-56), 5X (56-58), 6X (58-60).
Hat Size Estimator
Finding your hat size is simple. Wrap a soft measuring tape around your head just above your ears and across the middle of your forehead, following the line where your hat will sit. Keep the tape snug, not tight, then use the size chart below to find your best fit.
Measuring Tips
Measure around the widest part of your head, keeping the tape level from front to back. If your measurement falls between sizes, choosing the larger size is usually more comfortable.
Dress Shirt Size Estimator
Dress shirt sizing is based primarily on neck and sleeve measurements. For the best fit, use a soft measuring tape and, if possible, ask someone to help you measure accurately.
Neck Measurement
Measure around the base of your neck, below your Adam's apple, where a shirt collar naturally sits. Leave enough room to fit one or two fingers comfortably between the tape and your neck.
Sleeve Measurement
With your arm relaxed at your side, start at the center back of your neck, run the tape over the top of your shoulder, and measure down to your wrist.
