Key Measurements For A Suit Jacket

Suit Jacket/blazer sizes are typically determined by the following:

  • Collar Size
  • Sleeve Length
  • Chest Size
  • Waist Size
  • Body Length

Getting these measurements right ensures your jacket fits comfortably and looks sharp, without feeling too tight or baggy. Measuring your size correctly is essential if you decide to buy a suit online.

How to Measure Your Collar Size:

To measure your collar size, wrap the tape around the base of your neck where the collar would naturally sit. Make sure the tape is snug but not too tight. There should be enough room to slide two fingers between the tape and your skin. You can even round to the nearest half-inch to ensure comfort.

How to Measure Your Sleeve Size

To measure your sleeve size, start by placing the tape measure in the middle of your back, just below your neck. Extend it over your shoulder, down to your elbow, and continue to your wrist bone. This ensures you get the full length needed for a comfortable fit. 

You can measure from the shoulder seam, but measuring from the middle of the back ensures you are taking into consideration the full range of motion. In other words, providing a better fit for moving and reaching.

Tip: For an accurate measurement, keep your arm relaxed at your side rather than bending it, as this can affect the final length.

How to Measure Your Chest Size

To measure your chest size, stand straight with your arms relaxed at your sides. For accuracy, remove your shirt. Find the fullest part of your chest, usually around the nipple line. Lift your arms slightly and wrap the measuring tape around your back to the front. Make sure the tape is snug but not tight. When the ends meet at the front of your chest, note the measurement in inches.

How to Measure Your Waist Size

Measuring your waist size is similar to measuring your chest. Find the fullest part of your stomach, usually around your belly button. Wrap the measuring tape around your lower back and bring it to the front. Make sure the tape is snug but not tight. When the ends meet, hold the tape in place without squeezing and record the measurement.

How to Measure Your Body Length

To measure body length or shirt length, start by placing the tape measure at the base of the back of your neck. Measure down to where you want the jacket to end, which is usually in the middle of your buttocks. However, the exact length depends on your preference.

Common Mistakes to Avoid


Using a rigid tape measure
– Always use a soft, flexible tape measure for precise measurements.

Incorrect reference points – Whether measuring collar size, sleeve length, chest size, waist size, or body length, it’s crucial to measure at the correct spots. For example, misjudging where to measure around your neck or how to measure sleeve length can lead to a suit jacket that doesn’t fit properly. Make sure you understand the correct points for each measurement to ensure accuracy.

Not maintaining a neutral body position – Stand naturally without pulling in your stomach or puffing out your chest. Measurements should reflect your natural body shape to achieve the best fit.
