Can you shrink the waist of jeans?

Yes, you can shrink the waistband of your jeans with high heat. A combination of wet and dry heat work well to shrink denim quickly. 

Make sure to check the care label before proceeding with shrinking. Pre-shrunk jeans will not shrink, or may only shrink a tiny bit when using the hot water method. 

Additionally, the waist of jeans gets worn out easily and loosens up over multiple wears as time goes by. That means it can generally recover its elasticity through a simple wash and dryer method. 

However, you may wonder what are the correlation to the temperature, time, and the amount of shrinkage.

How much do jeans shrink in the waist?

Preshrunk denim jeans will not shrink very much, and may not shrink at all because it has been applied during the production process. In contrast, 100% cotton denim that has not been pretreated can shrink as much as 20% with the wet and dry heating method.

Jeans tend to shrink in hot water combined with a high heat clothes dryer. However, this depends on the manufacturer’s type of fabric and steps taken to prevent shrinkage during the production process. 

For example, the waist of preshrunk jeans only shrinks a little after washing and drying, while those that are not preshrunk tend to shrink quickly every time you wash and dry them.

In general, not every denim jeans will shrink the same amount. Among all denim varieties, cotton has the most potential for shrinkage, and generally speaking 100% cotton denim jeans can shrink by 20% of its original measurements. 

On the other hand, cotton blends shrink less. Such as 80% cotton and 20% polyester denim jeans shrink only 3% of their original size. Spandex and cotton respond well to the shrinking method, however they shrink less compared to 100% cotton since the spandex does not shrink at all.

Tips to Shrink Jeans Waist Permanently

Shrinking jeans waist in the wash is an easy way to fight stretched out waistband on denim. Other than setting highest temperature on washer and dryer, here are shrinking tips to permanently shrink jeans waist:

  • When drying jeans, let them dry completely. You can allow jeans to stay in the dryer for 5-10 minutes after drying to shrink the waistband permanently.
  • Keep checking to ensure the waistband is completely submerged in the water. If not, you can use tongs to push it inside the water, but don’t expose any other areas unless you want them to shrink as well.
  • Avoid air-drying jeans during the waist-shrinking process, this can cause your waist to stretch out instead. Stick with high heat to maximize shrinkage.
  • Soak waistband with any homemade laundry detergent and fabric softener. Detergent won’t affect your jeans, but fabric softener helps reduce the stiffness of the fabric during the shrinking process.
  • Always put wet jeans back on before they dry thoroughly. Trying them on while they are slightly damp will help the pants adjust perfectly to your body figure, especially the waist, when they dry completely.

Jeans naturally stretch with time and movement, but using a hot air dryer will benefit to permanently shrink the waist. As the fabric dries, the fibers will create a shrinking effect.

  • Place only the waistband of the denim jeans into the hot water, wait for 10 minutes while allowing the legs of the jeans to hang outside the vessel. Ensure to place it slowly to avoid splashing as the scalding hot water can be very dangerous.
  • Take a big towel and tongs, use them to remove the pants from the bucket. To get rid of most water, roll your jeans in the towel by placing the waistband flat on the towel and folding it over gently.

Shrinking Jeans Waistband: Conclusion

From taking a bath with denim jeans to spraying solution around the waistband, there are various methods to shrink jeans waist so they fit you snuggly. In my experience, soaking and drying at max temperature works the best, it is quick and easy solution to slim down ½” to 1” of the waistband opening without tailoring.

Double check if the jeans have been already preshrunk or not. If it is pretreated during the manufacturing process, then lengthen the soaking and drying time a bit longer than usual to get the maximum shrinkage available. 

Turn your denim inside out before washing and drying to prevent color from fading. 

Also, treat any stains out before throwing in the dryer. The hot air can easily set-in the stain to make it permanent, and once the stain is stuck on fabric, it is very difficult to remove.

Boil clean water and pour in a clean bucket or kitchen pot. Once the water is boiling turn off the heat and only soak the jeans waistband. 

Leave the legs of the jeans hanging or on top of lid so it does not fall into the hot water. If other parts of the jeans enter the hot water, then they are also susceptible to shrinkage as well.

Place your pants in the dryer and use the highest heat setting to dry. The heat will make the soaked areas with fabric softener solution shrink as it dries. 

Let it dry completely before removing from the dryer. Repeat the process if the waist didn’t shrink as much as you would like or stretches again after some time.

Shrink the waistband of your jeans by focusing the wet and dry heat only on the area of the pants. If other parts of the denim get wet, they will also shrink when exposed to high heat.
