Weight Loss Pant Size Calculator


Weight loss can often result in changes to more than just your body weight. As individuals lose weight, their clothing sizes, including pant sizes, might also change. To estimate the potential change in pant size due to weight loss, a Weight Loss Pant Size Calculator can be an invaluable tool.


The calculator uses a simple formula to estimate the new pant size based on the difference between the current weight and the target weight. For every 5-pound difference, it is estimated that there might be a change in the pant size.

How to Use

  1. Enter your current weight in pounds.
  2. Input your target weight in pounds.
  3. Provide your current pant size.
  4. Click the “Calculate” button to obtain the estimated new pant size based on weight loss.


For instance, if your current weight is 180 pounds, and your target weight is 150 pounds, and your current pant size is 34, the calculator estimates that your new pant size might be 32 after the weight loss.
