Clothes can indeed shrink in the washer, and it's not just a myth. This is because the fibers in the fabric can contract and lose their shape when exposed to high temperatures and agitation.
The risk of shrinkage is higher for certain types of fabrics, such as wool and silk, which can shrink by up to 30% in the wash.
To prevent shrinkage, it's essential to check the care label on your clothes and follow the recommended washing instructions.

Why Clothes Shrink
Clothes can shrink in the washer due to a combination of factors.
Some fabrics, like those made of loosely woven natural fibers, are more prone to shrinkage. Vigorous motion and high temperatures in washing and drying cycles constrict these natural fibers and distort materials, resulting in shrunken clothing.
Hot water can be particularly problematic, especially for natural fibers like cotton, wool, linen, or silk. When exposed to water temperatures above 80°F, these fibers may undergo Thermal Agitation, causing them to contract and the fabric to shrink.

This process can be permanent in some cases, especially for natural fibers that haven't undergone a "pre-shrinking" process during manufacturing. Clothing manufacturers often stretch fabrics to their max so that slightly less cloth is needed, but when you wash the garment, the fibers shrink back to their natural state.
Some fabrics are more sensitive to high temperatures than others. Here are some of the most prone to shrinking:
- Cotton (including denim and muslin)
- Wool (including flannel and cashmere)
- Linen
- Silk
- Bamboo
- Viscose
- Rayon
It's worth noting that synthetic fibers like nylon, polyester, and spandex are generally less prone to shrinkage. However, this doesn't mean they're completely immune to it.
Preventing Shrinkage
To prevent shrinkage, it's essential to wash your clothes in cold water. Washing clothes in cool or cold water (below 80°F) significantly reduces the risk of shrinkage, especially for natural fibers like cotton, wool, and linen.
Cold water washing also helps preserve the integrity of your fabrics, using up to 70% less energy than hot water. This is a win-win-win for your clothes, your energy bill, and the environment.

Some laundry detergents require warm water to dissolve, but high-performance laundry pods like Laundry Sauce can clean your clothes in cold water just as well as they would in hot water.
Here are some general guidelines for washing clothes in cold water:
Remember to check the care label on your clothes to ensure you're washing them according to their specific needs.
Does Detergent Cause?
Generally speaking, laundry products don't cause clothing to shrink. The two biggest factors that contribute to clothing shrinkage are temperature and cycle setting.
If you stick to avoiding heavy-duty washing cycles, fast spinning modes, and high-temperature washing/drying, your clothes will last much longer.
Some fabrics benefit from using a different detergent and care.
Washing wool, for example, requires a low temperature and a suitable laundry detergent that nourishes the wool fibers to minimize the risk of the garment shrinking.
Preventing Shrinkage in the Washer
Washing clothes in cold water is a great way to prevent shrinkage, especially for natural fibers like cotton, wool, and linen. Cold water washing also helps preserve the integrity of your fabrics and uses up to 70% less energy than hot water.
A different take: Water Plants
Hot water can cause unnecessary wear and tear on your clothes, leading to shrinkage. Lewenhaupt recommends washing clothes in cool or warm water instead, which is "kinder on your clothes." If you're worried about your clothes not getting clean enough, know that modern laundry detergents contain both enzymes and surfactants that are super effective even at colder temperatures.
The ideal washing temperature is usually around 85 degrees Fahrenheit, which is suitable for washing clothes made of synthetic blends, delicate items, and clothes and fabrics that are not heavily soiled. However, if you're washing intimate garments, such as underwear and bedding, you may need to use a higher temperature setting.
To prevent shrinkage, it's essential to check the care label on your clothes before washing them. The care label will indicate the best method for washing, drying, and ironing to ensure your garment stays in pristine shape.
Here are some laundry detergent options that are designed to clean clothes in cold water:
- High-performance laundry pods like Laundry Sauce
- Liquid laundry detergents that are specifically designed for cold water washing
By following these tips, you can help prevent shrinkage in the washer and keep your clothes looking their best.
Fabrics and Shrinkage
Some fabrics are more prone to shrinkage than others. Fabrics made of loosely woven natural fibers tend to shrink easily, especially when exposed to high temperatures and vigorous motion during washing and drying.
Nylon, polyester, and spandex are examples of synthetic fibers that don't shrink much.
Cotton, wool, linen, silk, bamboo, viscose, and rayon are fabrics that are most prone to shrinking. These organic materials tend to be sensitive to high temperatures, which causes the threads to curl up and move closer together.
Hot water can cause significant shrinkage in clothing, especially if it's made of natural fibers. In fact, water temperatures above 80°F can cause the fibers to contract and the fabric to shrink.
Linen is a natural fiber that can shrink when exposed to high heat. It's generally best to use cold to lukewarm water when washing linen items.
Here's a list of fabrics that are prone to shrinking in warm water:
- Cotton
- Wool
- Linen
- Silk
- Bamboo
- Viscose
- Rayon
Handling Delicate Fabrics
Fabrics made of loosely woven natural fibers are more prone to shrinkage, so it's essential to handle them with care. Vigorous motion and high temperatures in washing and drying cycles can constrict these fibers and distort materials, resulting in shrunken clothing.
To prevent shrinkage, it's best to wash delicate fabrics in cold temperatures and use no/low spin. This will help protect the fibers from heat damage. I've found that using a mesh laundry bag can also help reduce agitation and prevent shrinkage.
If a garment is labeled as "dry clean only", it's best to take it to a professional to avoid damaging or shrinking the garment. This is because dry cleaning only is an indicator that a garment has a high chance of shrinking or being damaged in the washer or dryer.
Here are some fabrics that are more prone to shrinkage and require special care:
- Cotton (including denim and muslin)
- Wool (including flannel and cashmere)
- Linen
- Silk
- Bamboo
- Viscose
- Rayon
Fixing and Preventing Shrinkage
If you're like me, you've probably experienced the frustration of clothes shrinking in the washer. It's a bummer, especially if you just got your favorite sweater or dress.
Washing clothes in cold water is a great way to prevent shrinkage. This is because hot water can cause fibers to contract and lose their shape.
Some fabrics, like cotton and wool, can be salvaged if they do shrink. Try soaking the garment in 1 gallon of lukewarm water with 1/3 cup of standard hair conditioner. This can help restore some of its original shape.
To prevent clothes from shrinking, skip the dryer altogether. This is because high heat can cause fabrics to shrink and lose their shape.
If you do end up with shrunken clothes, try the stretch and reshape method. Lay the damp garment on a flat, absorbent towel and gently stretch the fabric in all directions. Pay attention to specific areas that may have shrunk more, such as sleeves or length.
Here's a step-by-step guide to the stretch and reshape method:
- Lay the damp garment on a flat, absorbent towel.
- Gently stretch the fabric in all directions to restore some of its original shape.
- Paying attention to specific areas that may have shrunk more, such as sleeves or length.
- Leave the garment to air-dry in its stretched state.
For more stubborn shrinkage, consider taking your garment to a professional cleaner. They may be able to address the shrinkage and restore your garment to its original size.
Is my washing machine faulty?
If your washing machine is faulty, it can cause clothes to shrink in unexpected ways. A faulty temperature control can cause water to heat up too high, leading to excessive shrinkage.
Clothes that are washed in hot water can shrink up to 5% in the first wash alone. This is because the heat causes the fibers to contract and tighten.
If your washing machine is not spinning properly, it can lead to uneven drying and shrinkage. This is because the water is not being removed effectively, causing the clothes to become misshapen.
Some washing machines have a "hand-wash" or "delicate" cycle that uses cold water, which can help prevent shrinkage. However, it's essential to check your washing machine's manual to see if this cycle is available.
