Cotton, known for its natural breathability, comfort, and durability, is a favored fabric for clothing. Its ability to wick moisture away from the skin makes it suitable for all seasons. However, proper maintenance is essential to preserve cotton garments. While cotton can be prone to shrinking, there are effective strategies to prevent your favorite cotton clothing items, such as shirts, pants, or dresses, from losing their ideal fit.
Why does Cotton Shrink in the Dryer?
Cotton fabric has soft and breathable qualities, but it is more susceptible to shrinking compared to synthetic fibers like polyester. During the spinning process, the fibers of raw cotton are stretched, creating the necessary tension for weaving them into fabric. However, when cotton fabric is exposed to heat, such as in a dryer, the fibers lose their tension, resulting in slight shrinkage after the first wash.
How to Stop Cotton from Shrinking
Cotton may shrink, but there are steps you can take to ensure your cotton clothing maintains its perfect fit. When you purchase new cotton garments, it is advisable to hand wash them and air dry them initially. This process minimizes any potential shrinkage and allows the fabric to settle:
- Hand Washing: If time allows, hand wash your cotton clothing. Use a very mild detergent and cool water. Lightly scrub and soak the clothing for about five minutes for normal washes, or up to thirty minutes for more soiled clothing. After soaking, rinse the clothing thoroughly in cool water.
- Using a Washing Machine: If you don't have time for hand washing, it's acceptable to use a washing machine. To prevent shrinking, wash your cotton clothing on a delicate cycle and with cold water. This reduces the risk of excessive friction and agitation, which can cause shrinking and unwanted wear, such as pilling.
- Air Drying: Regardless of whether you hand wash or use a washing machine, it is best to dry your cotton clothing without heat. High temperatures are the quickest way to shrink cotton clothes. Avoid using the dryer and dry cloths in the air. Using hangers can help maintain the shape of the garments.
These guidelines specifically apply to 100% cotton clothing items. If the label of your clothing indicates a cotton and polyester blend, you don't need to worry as much about shrinkage. Polyester, being a synthetic fiber, does not shrink when exposed to heat. For cotton-polyester blends, you can wash the clothing in cool or warm water and dry it on a low setting in the dryer.

What Dryer Setting Shrinks Cotton?
The dryer setting plays a significant role in cotton shrinkage. The use of high heat settings in the dryer can cause cotton fabric to shrink more rapidly. Therefore, it is advisable to choose a low or medium heat setting when drying cotton garments. Air drying is the gentlest option as it eliminates the risk of heat-induced shrinkage entirely.
What Temperature Does Cotton Start to Shrink?
Cotton fabric typically begins to shrink at temperatures above 120 degrees Fahrenheit or 49 degrees Celsius. At these temperatures, the cotton fibers start to tighten and contract, resulting in a decrease in the fabric's size. It is important to note that this temperature threshold may vary slightly depending on the specific cotton fabric and its manufacturing process.
What Temperature Does Cotton Not Shrink?
Cotton does not shrink significantly when exposed to temperatures below 120 degrees Fahrenheit or 49 degrees Celsius. Therefore, washing cotton fabric in cold water and air-drying are effective ways to prevent shrinkage. Additionally, lower heat settings on dryers can help minimize shrinkage.

How Much Will 100% Cotton Shrink?
The amount of shrinkage in 100% cotton fabric can vary, but typically it ranges from 3% to 5% in both length and width. However, this percentage can increase if the fabric is not properly cared for during washing and drying. By following the above mentioned prevention methods, you can significantly reduce the amount of shrinkage in 100% cotton garments.
Faqs
Does drying on high heat shrink cotton?
Drying on heat can cause significant shrinkage. Instead, gently squeeze out excess water from the garments and air dry them on a flat surface or hang them on a clothesline. This method helps preserve the fabric's shape and prevents further shrinking.
Does cotton shrink on low heat?
Cotton may shrink slightly on low heat, but the shrinkage is generally minimal.
How many sizes does cotton shrink?
Cotton can shrink up to one size when laundered, but it varies depending on the fabric and the washing method.
Does 60% cotton shrink in the dryer?
A 60% cotton blend may shrink slightly in the dryer, but the shrinkage is usually limited.
Does 80% cotton shrink in the dryer?
An 80% cotton blend might experience some shrinkage in the dryer, but it's typically not significant.
Does 100% cotton always shrink?
Yes, 100% cotton fabric has a tendency to shrink when washed and dried, so it's important to follow proper care instructions.
