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)

To calculate the weight loss pant sizes, divide the weight lost in pounds by 10.

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.

FAQ

How accurate is the weight loss pant size formula?

The weight loss pant size formula provides a general estimate and is not exact. It assumes an average distribution of weight loss and does not account for individual differences in body composition or where a person tends to lose fat first. The actual number of pant sizes lost can vary based on factors such as body shape and where the individual carries their weight.

Can weight loss calculators help in planning a weight loss journey?

Yes, weight loss calculators can be a helpful tool in planning a weight loss journey. They can provide estimates on how long it might take to reach a certain weight loss goal, the percentage of body weight lost, and even the impact of weight loss on clothing sizes. However, it’s important to remember that these calculators provide estimates based on averages and should be used as part of a broader approach that includes diet, exercise, and consultation with healthcare professionals.

Is it possible to lose weight in specific areas of the body to affect pant sizes more significantly?

While it’s a common desire to lose weight in specific areas, such as the waist or hips, to affect pant sizes more significantly, it’s not possible to target weight loss to specific body parts, a concept known as “spot reduction.” Weight loss generally occurs across the entire body based on genetics, body composition, and overall fat percentage. However, combining overall weight loss with strength training and exercises targeting specific muscle groups can help tone those areas and potentially influence how clothing fits.
