Enter the total number of pounds of weight loss into the calculator to determine the number of pant sizes lost.

Weight Loss Pant Size Formula

The following formula is used to calculate the total amount of pants sizes lost when losing weight.

PSL = WL / 10

  • Where PSL is the number of pant sizes lost
  • WL is the total amount of weight lost (lbs)

How much weight do i need to lose to drop pants size?

On average, every 10 lbs of weight a person loses will equate to 1 pant size smaller. So, for example, if someone lost 25 pounds, they would likely drop 2 and a half sizes in pants.

This is not an exact formula, and the number of pants sizes lost will also depend on where a person stores their fat. If a person stores more fat on their hips, they would likely lose more pants sizes than someone that stores fat more on their thighs and arms.

How to calculate weight loss pant sizes?

Example:

The following example shows how to calculate the equivalent number of pants sizes lost given the number of pounds someone has lost.

First, determine the total number of pounds of weight the person has lost. In this example, the person has lost a total of 20 lbs.

Next, calculate the number of pants sizes lost using the formula above:

PSL = WL / 10

PSL = 20 / 10

PSL = 2

Finally, subtract the number of pants sizes lost from the previous pant size to determine the new pant size. In this case, the person was originally a 34, so now they are a size 32 waist.
