How To Measure Your Jacket Size In 7 Simple Steps


Finding the perfect jacket is about more than just selecting a style that catches your eye. Imagine slipping into a jacket that fits like it was made just for you, enhancing your look while allowing you to move comfortably. Achieving this ideal fit starts with knowing how to measure your jacket size accurately. In this guide, we'll walk you through the essential steps to ensure your jacket fits perfectly every time.

Why Measuring Your Jacket Size Matters

Wearing a jacket that fits well is not just about aesthetics but also comfort and functionality. A properly fitting jacket allows you to move freely and enhances your overall look. Ill-fitting jackets, on the other hand, can be restrictive and spoil your outfit.



Tools You’ll Need

Before you begin, gather the following tools to make the measurement process easier:

  • A soft measuring tape
  • A notepad and pen to jot down your measurements
  • A full-length mirror
  • A friend to help (optional but useful)

Step 1: Measure Your Chest

The chest measurement is crucial for determining your jacket size. Here’s how to do it:

  • Stand upright with your arms relaxed at your sides.
  • Wrap the measuring tape around the fullest part of your chest, typically right under your armpits and across your shoulder blades.
  • Ensure the tape is level and snug but not too tight. You should be able to fit a finger between the tape and your body.
  • Record the measurement in inches or centimeters.

Tip: For an accurate reading, take this measurement while wearing a shirt or a thin layer that you would typically wear under a jacket.

Step 2: Measure Your Waist

Your waist measurement helps determine the fit of the jacket around your midsection. Here’s how to measure it:

  • Stand straight and locate your natural waistline, which is usually the narrowest part of your torso, just above your belly button.
  • Wrap the measuring tape around your waist, ensuring it’s level all the way around.
  • Keep the tape snug but not constricting, and breathe normally as you measure.
  • Note down the measurement.

Tip: Avoid sucking in your stomach while measuring, as this will give you an inaccurate size.

Step 3: Measure Your Hips

If you’re purchasing a longer jacket or a coat, measuring your hips is essential:

  • Stand with your feet together.
  • Wrap the measuring tape around the fullest part of your hips and buttocks.
  • Ensure the tape is level and snug without squeezing.
  • Write down the measurement.

Tip: Wear the type of clothing you usually wear under jackets to get the most accurate hip measurement.

Step 4: Measure Your Shoulders

Shoulder width is another critical measurement for a good jacket fit:

  • Stand straight and locate the ends of your shoulder bones, which is where the shoulder seam of your shirt typically ends.
  • Have a friend help you measure the distance from one shoulder end to the other across your back.
  • If measuring alone, use the mirror to ensure the tape is straight and level.
  • Record this measurement.

Tip: For tailored or structured jackets, a precise shoulder measurement ensures that the seams sit correctly on your body.

Step 5: Measure Your Sleeve Length

Sleeve length is important to ensure your jacket covers your arms appropriately:

  • Place your hand on your hip with your arm bent at a 90-degree angle.
  • Have a friend measure from the top of your shoulder (where the shoulder seam sits) down to your wrist.
  • If measuring alone, it might be easier to measure from the top of your shoulder to your elbow and then from your elbow to your wrist, adding these measurements together.
  • Note the total measurement.

Tip: Jackets should generally end at your wrist bone, covering your watch but not your hand.

Step 6: Measure Your Jacket Length

The length of your jacket is a matter of personal preference, but here’s how to measure for standard fits:

  • Start at the top of your shoulder, near the base of your neck.
  • Measure straight down to your desired jacket length. For most jackets, this will be to your hips, mid-thigh, or knees.
  • Record this measurement.

Tip: For formal jackets, the hem should typically cover your buttocks, whereas casual jackets can be shorter.

Step 7: Check Your Neck Size

For jackets with collars, knowing your neck size ensures a comfortable fit:

  • Wrap the measuring tape around the base of your neck, where a collar would naturally sit.
  • Make sure the tape is snug but not too tight, allowing for a finger to fit comfortably between the tape and your neck.
  • Record this measurement.

Tip: If you find the measurement slightly restrictive, add half an inch to ensure comfort.

Understanding Jacket Sizes

Once you have all your measurements, you need to understand how they translate into jacket sizes. Jacket sizes typically come in standard sizes (such as small, medium, and large) or numerical sizes (such as 38, 40, 42). Here’s a brief guide to help you convert your measurements:

Chest Measurement:

34-36 inches: Small (S) or 34-36

38-40 inches: Medium (M) or 38-40

42-44 inches: Large (L) or 42-44

46-48 inches: Extra Large (XL) or 46-48

Waist Measurement:

Ensure your waist measurement falls within the range for the chest size. Some brands offer different fits (slim, regular, athletic) to accommodate various body types.

Sleeve Length:

Match your sleeve length with the jacket size chart. If you find a jacket that fits well in the chest but is too long or short in the sleeves, consider custom tailoring.

Tips for Different Jacket Styles

Different jacket styles require slightly different fits. Here’s how to ensure you get the right size for various jacket types:

Blazers and Suit Jackets

  • Ensure a snug fit around the shoulders and chest.
  • The jacket should taper slightly at the waist for a tailored look.
  • The sleeve length should end at your wrist bone, allowing for a quarter inch of your shirt cuff to show.

Casual Jackets

  • These can have a more relaxed fit, allowing for layers underneath.
  • Ensure enough room in the chest and shoulders for movement.
  • Jacket length can vary; choose what feels most comfortable for your style.


  • Leave room for layering underneath without making the jacket look too bulky.
  • Consider the type of closure (zippers, buttons) and how it affects the fit.
  • Ensure the sleeves are long enough to keep you warm but not so long that they cover your hands.

Common Fit Issues and Solutions

Even with accurate measurements, you might encounter some common fit issues. Here’s how to address them:

  • Tight Shoulders: If your jacket feels tight across the shoulders, you might need to size up or choose a different style with more room in the shoulder area.
  • Loose Waist: A loose waist can be tailored for a better fit. Look for jackets that offer a slim or tailored fit if you consistently encounter this issue.
  • Short Sleeves: Sleeves that are too short can be lengthened slightly by a tailor, but there’s a limit to how much fabric is available. Consider sizing up if this is a recurring problem.
  • Long Jacket Length: If the jacket is too long, a tailor can shorten it to your preferred length. This is a common alteration for achieving a perfect fit.

Final Tips for Buying a Jacket

Now that you know how to measure your jacket size, here are some final tips to keep in mind when shopping for a jacket:

  • Try Before You Buy: Whenever possible, try on jackets before purchasing. Sizes can vary significantly between brands, and trying on different styles will help you find the best fit.
  • Consider Custom Tailoring: For the best fit, consider getting your jacket tailored. Even minor adjustments can make a significant difference in comfort and appearance.
  • Know Your Fabric: Different fabrics drape differently on the body. Wool, cotton, and synthetic blends each have unique properties that can affect fit and comfort.
  • Check the Return Policy: Always check the return policy before purchasing, especially if buying online. This ensures you can return or exchange the jacket if it doesn’t fit as expected.
