How To Calculate Waist Size

Introduction: Maintaining a healthy waist size is important for overall well-being. This article introduces a calculator designed to help you estimate your waist size based on your height and a specified waist-to-height ratio.

Formula: The formula used in this calculator assumes a linear relationship between height and waist-to-height ratio. The estimated waist size is obtained by multiplying the height by the waist-to-height ratio.

How to Use:

  1. Enter your height in inches.
  2. Input the desired waist-to-height ratio (a common guideline is around 0.5).
  3. Click the “Calculate” button to get the estimated waist size in inches.

Example: If your height is 70 inches and you aim for a waist-to-height ratio of 0.5, the calculation would be: 70 * 0.5 = 35. Therefore, the estimated waist size would be 35 inches.
