Enter your height and weight into the calculator to estimate your neck circumference. This calculator uses a simple formula based on average body proportions to provide an estimate of neck size.

Neck Circumference Formula

The formula used to estimate neck circumference is based on a combination of height and weight.

NC = frac{H_{in} / 39.3701 + W_{lb} / 2.20462}{2}

Variables:

  • NC is the neck circumference (inches)
  • Hin is the height (inches)
  • Wlb is the weight (pounds)

To estimate the neck circumference, convert the height from inches to meters and the weight from pounds to kilograms, then average the two values.

What is Neck Circumference?

Neck circumference is a measurement around the neck, typically used as an indicator of health and fitness. It can be correlated with body fat distribution and is sometimes used in conjunction with other measurements to assess risk factors for certain health conditions. It is also used in tailoring for clothing sizes.

How to Calculate Neck Circumference?

The following steps outline how to estimate the Neck Circumference.


  1. First, measure your height (Hin) in inches.
  2. Next, measure your weight (Wlb) in pounds.
  3. Use the formula NC = (Hin / 39.3701 + Wlb / 2.20462) / 2 to estimate the neck circumference.
  4. Finally, calculate the Neck Circumference (NC) in inches.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.
