Have you ever bought a shirt or a pair of pants made of cotton and wondered if they would shrink in the wash? If so, you’re not alone.
Many people have experienced the frustration of purchasing clothes that seem to fit perfectly in the store, only to find that they are too small after the first wash.

The question of whether does 80 cotton shrink is a common one, and the answer is not always straightforward. The amount of shrinkage that occurs depends on a number of factors, including the weight and thickness of the fabric, the weave, and the type of cotton used.
However, as a general rule, it is safe to assume that clothing made of 80% cotton will shrink between 5 and 10%.
If you’re worried about your clothes shrinking in the wash, there are steps you can take to minimize the risk. For example, you can wash your clothes in cold water and hang them to dry instead of using a dryer. Additionally, you can look for clothes that are labeled as “pre-shrunk” or “shrink-resistant” to ensure that they will maintain their size and shape after washing.
What is 80% Cotton?
If you’re wondering what 80% cotton means, it simply means that the fabric is made up of 80% cotton fibers and 20% other fibers, which could be polyester, rayon, or other materials. Cotton is a popular fabric choice because it is soft, breathable, and comfortable to wear. It’s also easy to care for and can be machine washed and dried.
Cotton fibers are strong, durable, and absorbent, which means that they can hold up well to wear and tear and can absorb moisture without feeling damp or uncomfortable.
Factors that Affect Cotton Shrinkage
Water Temperature
Hot water can cause cotton to shrink more than cold water. According to Lands’ End, using warm water between 105-120°F is the best temperature for washing cotton. However, if you want to intentionally shrink your cotton item, using hot water can help achieve that.
Drying Method
Using a dryer on high heat can cause cotton to shrink more than air-drying or using a low heat setting.
Fabric Treatment
According to Sewing Feed, using a fabric softener or conditioner can cause cotton to shrink less than if it was washed without any treatment. However, using too much fabric softener can cause the opposite effect and actually increase shrinkage.
Type of Cotton
Sew Insider notes that combed cotton has a tighter and smoother weave than carded cotton, making it shrink less. Mercerized cotton, which has gone through a special process, can also shrink less than other types of cotton fabrics.
By paying attention to water temperature, drying method, fabric treatment, and type of cotton, you can minimize or intentionally achieve shrinkage in your cotton items.
Will 80% Cotton Shrink?
If you are wondering whether your 80% cotton garment will shrink, the answer is yes, it most likely will.
Cotton, a natural fiber, can shrink when heated or exposed to moisture, though the extent of this shrinkage varies based on the fabric weight, weave, and type of cotton.
Shrinkage Percentage
On average, an 80% cotton garment will shrink between 5% and 10%, according to Sew Insider. However, this is just an estimate and the actual shrinkage percentage can vary.
Preventing Shrinkage
If you want to prevent your 80% cotton garment from shrinking, there are a few things you can do:
- Wash your garment in cold water instead of hot water.
- Avoid using the dryer and instead hang your garment to dry.
- Choose a fabric blend that is less likely to shrink, such as a cotton-polyester blend.
Care Instructions
- Wash your garment in cold water with a gentle detergent.
- Avoid using bleach or fabric softeners as they can damage the fibers.
- Hang your garment to dry or use a low-heat setting on your dryer.
- If ironing is necessary, use a low heat setting and iron the garment while it is still slightly damp.
By following these tips, you can help prevent your 80% cotton garment from shrinking and keep it looking great for years to come.
Does Cotton Shrink?
Yes, cotton can shrink. Cotton fabric is known for its tendency to shrink when exposed to heat and moisture, particularly during the first wash.
It’s important to note that not all cotton fabrics shrink equally. Mercerized cotton, for example, is less likely to shrink than combed or carded cotton. Additionally, cotton blends that contain synthetic fibers like polyester or spandex are less likely to shrink than 100% cotton fabrics.
Avoid washing cotton fabrics in hot water, and opt for a gentle cycle with cold water instead. Additionally, avoid drying cotton fabrics on high heat, and instead, air dry or tumble dry on low heat.
Here are some additional tips to prevent cotton shrinkage:
- Pre-wash your cotton fabric before sewing or wearing to remove any excess chemicals and to pre-shrink the fabric.
- Hand wash or dry clean delicate cotton fabrics to avoid shrinkage.
- Stretch cotton fabrics while they’re still damp to help maintain their shape.
- Iron cotton fabrics while they’re still damp to help prevent shrinkage.
How Much Will 80 Cotton Shrink?
When it comes to clothing, one of the more frequent inquiries is how much they will contract after a wash. A range of elements influence this, such as the fabric’s mass, weave, and the kind of cotton employed. For garments made of 80% cotton, shrinkage can usually be between 5 and 10%.
It’s noteworthy that the amount of shrinkage a fabric experiences is not always determined by the percentage of cotton alone. The inclusion of synthetic fibers can also come into play, altering the fabric’s response to heat and water. This is the reason why fabrics containing 80% cotton and 20% synthetic fibers may not contract as much as fabrics composed entirely of natural fibers.
However, it’s still important to take proper care of clothing items made with 80% cotton to minimize shrinkage. This includes washing them in cold water and avoiding high heat when drying.
Overall, while 80% cotton may not shrink as much as 100% cotton, it’s still important to take proper care of clothing items to prevent any unwanted shrinkage.
How to Shrink Cotton
Here are a few methods you can try:
Method 1: Boiling Water
Here’s how:
- Fill a large pot with water and bring it to a boil.
- Turn off the heat and add your cotton garment to the pot.
- Let the garment sit in the hot water for about 30 minutes.
