Port Authority J405 Men's Waterproof Tech Jacket - Insulated, Adjustable Hood

A well-fitting jacket or coat is a must-have for every wardrobe and an
essential layering piece. However, how should I measure the jacket's size?
Before you use a jacket size calculator or consult a men's or women's jacket
size chart, you'll need to take a few body measures. We'll show you how to
accurately take these essential measures in this in-depth tutorial so you can
select the ideal jacket size. Now let's get going.

Important Notes

To take accurate body measures, you'll need a non-stretchable fabric
measuring tape, a pen, paper to record your dimensions, and someone to assist you. Make sure you're wearing a fitting t-shirt with no extra layers. Stand up straight and calmly. Do not push out or tuck in your stomach.

1. Neck: How Do I Measure My Jacket's Neckline?

To find your neck measurement, wrap the tape measure around your neck circumference and place your middle and index fingers underneath it for comfort.

2. Shoulders: How Do I Measure My Shoulder For A Jacket?

Position the measuring tape above the shoulders and proceed to measure from the left shoulder's edge across the nape of the neck to the right shoulder's edge.

3. Sleeves: How Do You Measure Jacket Sleeve Lengths?

Position the measuring tape over the shoulders (seam of t-shirt) and proceed to the end of your wrist.

4. Biceps: How Do You Measure Them for a Jacket?

Your upper arm's widest region is your bicep, so measure that area by wrapping the tape measure around its circumference.

5. Bust or Chest: How Do I Determine a Jacket's Chest Size?

To provide an exact measurement, wrap the tape over the widest area of the chest or breast. Ensure that the tape is evenly level throughout.

6. Natural Waist: Jacket Upper Waist Measurements

The natural waist, also known as the upper waist, is the smallest portion of the waist, located an inch or two above the belly button. Bending to one side will also help you find it with ease. To find your lower waist measurement, measure the circumference of this region.

7. Lower Waist: Jacket Lower Waist Measurement Procedure

Different from the natural waist, the lower waist is measured at the broadest point, which is often at or slightly below the belly button. To determine your lower waist size, locate the location and measure the diameter surrounding it.

8. Center Back: How Do You Measure the Length of a Jacket?

Finding your center of gravity is the most accurate method of estimating the length of your jacket. Position the tape vertically to the middle of your waist or the desired ending point of your hemline, starting from the back of your neck or shoulder blade.

9. Hips: Taking Hip Measurements for Jackets

The correct hip size is also required for longer coats that sit on the broadest area of your hip. This measurement may be obtained by measuring the circumference around the widest portion of your hips.

10. Wrist: How the Wrist Is Measured for Jacket Sleeves

The sleeves taper to the wrist, which is the thinnest section of the sleeve. Take a measurement of your wrist by wrapping the tape measure around the area that is directly above your wrist bone.

11. Sleeve Inseam: How To Measure Inseam Of Jacket

Here are all the dimensions needed to get a good, well-fitting coat or jacket. Whether it's a ready-to-wear size or one made especially for you, these guidelines will help you measure your body accurately and select the best-fitting clothing. It's also critical to check the measurement unit on a size chart. Because the imperial measuring system is regarded as the norm, a US jacket size chart will often be in inches. Because the metric system is officially used in Europe and the UK, it is likely that a UK jacket size chart will be in centimeters. Be careful to check which one fits where before making a purchase!
