How to Measure for Dress Shirts vs. Suit Jackets
Achieving a polished look in men’s formal wear starts with accurate measurements. Whether choosing a crisp dress shirt or a dapper suit jacket, understanding the differences in sizing ensures confidence and comfort in any setting—from office outfits to men’s wedding attire.
How to Measure for a Dress Shirt
Dress Shirt Neck Size
Wrap a loose measuring tape around the base of your neck, allowing room for movement (typically one finger’s width). A tight fit feels restrictive, while a loose fit looks unkempt. Your neck size (e.g., 15.5) determines your collar size.
Sleeve Length Measurement
Measure from the center of your back at the base of your neck, across the shoulder, and down to your wrist. This measurement in inches determines your sleeve size. Some brands, like Steven Land, sell sleeves in ranges (e.g., 34/35) for a more flexible fit.
Another feature to consider when choosing a dress shirt for formal wear or wedding attire is collar style, which can subtly enhance your overall look.
How to Measure for a Suit Jacket
A suit jacket uses a combination of a number and a letter (e.g., 40R). Here's what they mean:
Chest Measurement
Wrap the measuring tape around the fullest part of your chest, under your armpits, ensuring a level and snug fit. This number in inches determines your suit size (e.g., 40R).
Suit Jacket Length
Hold the measuring tape at the top of your shoulder, let it hang down until it reaches the bottom of your pants zipper. If it reads between 28 and 29 inches, your jacket is a short (e.g., 40S). If you are between 30 and 31 inches is a regular (e.g.,40R); and between 31 and 33 inches is a long (e.g., 40L). Anything longer than 33 inches is an extra long jacket size.
Knowing how to measure for a dress shirt and a suit jacket ensures a refined, tailored look. Whether upgrading your wardrobe or dressing for a formal event, precise measurements are the key to impeccable style.
