Does 100% cotton shrink? This question often rings in our sleep when we fall in love with a charming textile, only to worry if it will lose its appeal after the first wash. The answer is simple: yes, 100% cotton can shrink as much as any natural fiber such as linen, rayon, or wool.

However, there are essential tips to ensure that your favorite cotton duvet, attire, or any cotton-based product retains its quality and charm. In this article, we will guide you through the best way to make sure you can enjoy the beauty and comfort of 100% cotton without worrying about shrinkage. 


Why does cotton shrink?

Cotton is made up of natural fibers that can shrink when exposed to hot water or high heat. When cotton fibers are exposed to hot water or heat, the fibers can contract or shrink, which can cause the fabric to shrink overall. Additionally, cotton fibers can also shrink in the dryer due to the high heat often used in drying cycles.

Cotton fibers

One reason cotton can shrink is due to the nature of its fibers. Cotton fibers are woven together in a pattern, and when exposed to heat or moisture, these fibers can tighten and cause the fabric to shrink. The tighter the weave of the fabric, the more prone it is to shrink after washing or drying.

Hot water

Hot water can also cause cotton to shrink. When exposed to hot water, the fibers in cotton can again contract or tighten, which can cause the fabric to shrink. For this reason, it’s important to always wash cotton fabrics in cold water to prevent shrinkage.


The heat from the dryer can also cause cotton to shrink. While some cotton fabrics may be able to tolerate some heat in the dryer, it’s always best to use a low heat setting or air dry to avoid shrinkage.

How Much Will 100% Cotton Shrink?

Pre-Shrunk Cotton

Some cotton fabrics are pre-shrunk, which means the fabric has undergone a process to reduce shrinkage. However, even pre-shrunk cotton can still shrink when exposed to high heat or hot water.

Following Care Label Instructions

Before washing your cotton item, check the care label instructions to see if the material has any special care requirements. Following these instructions can help mitigate shrinkage and prolong the life of the material.

Shrinkage Percentage

The amount of shrinkage a cotton item experiences can vary depending on the fabric type, how it’s made, and how it’s cared for. In general, cotton can shrink 2-5% when washed and dried normally.

Can You Prevent Cotton from Shrinking?

Careful Washing

One of the best ways to prevent cotton from shrinking is by washing it carefully. This means using cold or lukewarm water, which won’t cause the fibers to expand as much. Use a gentle cycle and avoid heavy agitation, which can damage the fabric.

Cold Water Washing

As mentioned earlier, hot water is a leading cause of cotton shrinkage. By washing cotton with cold water, you can reduce the likelihood of shrinkage. If the item is particularly dirty, consider pre-treating it with a stain remover before washing.

Avoiding the Dryer

As with hot water, the dryer can also cause substantial shrinkage. Instead, try laying the garment or bed sheet flat to dry. This method can take longer, but it will help prevent shrinkage.

Dealing with Shrunk Cotton Clothes and Bed Sheets

Stretching Shrunk Clothes

If your cotton item has already shrunk, there are ways to stretch it back to size. First, wet the garment or bed sheet with lukewarm water. Then, gently stretch the fabric back into shape. You can also try using an iron on low heat to stretch the fabric.

Washing Shrunk Bed Sheets

If your cotton bed sheets have shrunk, you can try washing them with lukewarm water and mild detergent. Then, stretch them out while they’re still damp to help restore their original size.

Using Polyester or Synthetic Fiber Blends

Polyester and synthetic fiber blends are less likely to shrink than pure cotton. Consider purchasing cotton items that have synthetic materials blended in to help prevent shrinkage.

What is Sanforized Cotton?

Definition of Sanforization

Sanforization is a process used to pre-shrink cotton fabrics before they are made into garments or bedding. The process involves running the fabric through a machine that stretches and compresses it to reduce shrinkage.

Benefits of Sanforized Cotton

Sanforized cotton garments and bedding are less likely to shrink after washing, even when exposed to hot water or high heat in the dryer. This can help prolong the life of the material and make caring for it easier.

Where to Find Sanforized Cotton Products

Many brands offer sanforized cotton garments and bedding. Look for items labeled as pre-shrunk or sanforized to ensure the least amount of shrinkage possible.

Conclusion and final thoughts 💭

In conclusion, cotton can shrink, but there are steps you can take to prevent or mitigate it. By following these tips and understanding why cotton shrinks, you can prolong the life of your cotton garments and bedding. Washing 100% cotton fabrics in cold water is the best way to prevent shrinking. Hot water can cause the fibers to tighten and shrink, while cold water will not have the same effect. Always read the care label to make sure you’re washing the fabric in the correct temperature of water.
