Introduction - Why Shrink Sweatshirts One Size?

Sweatshirts are a beloved and versatile wardrobe staple. However, sometimes sweatshirts can be a bit too loose or oversized, making them less comfortable or flattering to wear. In such cases, shrinking the sweatshirt by one size can help achieve the perfect fit. Shrinkage can be particularly useful if you've recently lost weight or purchased a sweatshirt that is slightly larger than your size. This article will guide you through various methods to effectively shrink sweatshirts without damaging the fabric or compromising the quality. Whether it's a beloved vintage sweatshirt or a new purchase, shrinking it can be a cost-effective alternative to buying a new one.

Method 1: Machine Washing and Drying

Machine washing and drying is the most common method to shrink a sweatshirt. Here's how you can do it:

  • Check the garment's care label to ensure it can be machine washed and dried. Some sweatshirts may have specific instructions that prevent them from being washed in hot water or machine dried.
  • Set the washing machine to the hottest water setting and the longest wash cycle. Hot water helps shrink the fabric fibers.
  • Add a small amount of laundry detergent and turn the sweatshirt inside out to protect the outer design or any screen prints.
  • Place the sweatshirt in the machine and start the wash cycle.
  • Once the washing cycle is complete, transfer the sweatshirt to the dryer. Set the dryer to the highest heat setting and the longest drying cycle.
  • Monitor the drying process closely to ensure the sweatshirt doesn't shrink too much. Remove it from the dryer once it has reached the desired size.
  • Let the sweatshirt cool down before trying it on. This allows the fabric to stabilize and prevents any potential fabric damage.


While machine washing and drying can effectively shrink a sweatshirt, it's important to consider the following precautions:

  • Always check the care label instructions before using any method to shrink a sweatshirt. Some sweatshirts may require specific care.
  • Avoid using this method for sweatshirts made from delicate or sensitive materials such as wool or silk. These fabrics can easily be damaged by high heat or agitation.
  • Keep in mind that excessive shrinkage may result in the sweatshirt becoming too small or losing its shape. Monitor the process closely to achieve the desired size without compromising the quality and fit.

Method 2: Boiling Water Soak

Another method for shrinking a sweatshirt is through a boiling water soak. This method works well for cotton or cotton-blend sweatshirts. Follow these steps:

  • Fill a large pot with water and bring it to a rolling boil.
  • Turn off the heat and carefully place the sweatshirt into the boiling water.
  • Allow the sweatshirt to soak in the hot water for about 30 minutes.
  • Using heat-resistant gloves or tongs, remove the sweatshirt from the water and wring out any excess moisture.
  • Stretch and manipulate the sweatshirt while it's still damp to achieve the desired size and shape. Be careful not to overstretch or damage the fabric.
  • Hang the sweatshirt to dry or use a dryer on a low heat setting if necessary.
  • Try on the sweatshirt once it's completely dry to ensure it has shrunk to the desired size.


While the boiling water soak method can effectively shrink a sweatshirt, it's important to consider the following precautions:

  • Ensure that the sweatshirt is made from a fabric that can withstand high temperatures and boiling water without being damaged.
  • Be cautious while handling the boiling water to avoid burns or accidents. Use appropriate heat-resistant gloves or tools.
  • Stretch and manipulate the sweatshirt gently to avoid damaging the fabric or altering the intended structure.
  • Always let the sweatshirt dry thoroughly before trying it on to ensure its size and fit have been appropriately adjusted.

Method 3: Steam Treatment

Steam treatment is a gentle method to shrink a sweatshirt. It's suitable for sensitive fabrics or sweatshirts that only need a slight adjustment in size. Follow these steps:

  • Hang the sweatshirt in a bathroom with hot running water or in a steamy environment, such as a closed bathroom after a hot shower. This allows the fabric to absorb the steam and naturally shrink.
  • Alternatively, use a handheld garment steamer to steam the sweatshirt directly. Move the steamer over the fabric, focusing on areas that need to be shrunk.
  • While the fabric is still damp from the steam, gently stretch and manipulate the sweatshirt to the desired size.
  • Let the sweatshirt air dry or use a dryer on a low heat setting if necessary.
  • Try on the sweatshirt once it's completely dry to ensure it has shrunk to the desired size.


When using the steam treatment method, keep the following precautions in mind:

  • Take care not to overexpose delicate fabrics or sensitive materials to excessive steam, which may damage or weaken the fabric.
  • Ensure that the sweatshirt is not in direct contact with hot water or a steam source to prevent scalding or discoloration.
  • Be gentle while stretching and manipulating the damp sweatshirt to avoid any damage or distortion.

Method 4: Tailoring or Alterations

If you're not comfortable shrinking your sweatshirt at home or if you're unsure about the results, consider taking it to a professional tailor or alteration service. These experts can resize the sweatshirt to the desired size while maintaining its quality and structure. They have the expertise and equipment to make precise alterations and ensure the best fit for your sweatshirt.


When opting for professional tailoring or alterations, keep in mind the following:

  • Research reputable tailors or alteration services that have experience working with sweatshirts or similar garments.
  • Provide clear instructions and communicate your desired size and fit to the tailor or alteration specialist.
  • Discuss any concerns or potential risks associated with altering the sweatshirt to ensure you're making an informed decision.
  • Consider the cost associated with professional services compared to other shrinking methods.

Exploring Alternative Methods

In addition to the methods mentioned above, there are a few alternative approaches you can try:

  • Handwashing and Air Drying: Handwashing the sweatshirt in hot water and air-drying it can help shrink the fabric gently without the agitation of a washing machine or the high heat of a dryer.
  • Stretching: For certain fabrics, gentle stretching while the sweatshirt is damp can help adjust its size. Be cautious not to damage or distort the fabric.
  • Boiled Potato Soak: Some people claim that soaking a sweatshirt in boiled potato water can cause it to shrink. However, this method lacks scientific evidence, and the results may vary. Proceed with caution and be aware of potential discoloration.

Remember, results may vary with these alternative methods, and it's essential to be cautious and considerate of the fabric and quality of your sweatshirt.


Shrinking a sweatshirt by one size can be a cost-effective and simple solution when you're looking for a better fit. From machine washing and drying to boil-soaking and steam treatment, there are several methods you can try at home. However, always exercise caution and consider the fabric type and any specific care instructions. If you're unsure or prefer professional assistance, consult a tailor or alteration service. Remember to monitor the shrinking process to avoid excessive shrinkage or fabric damage. By following the appropriate methods and precautions, you can successfully shrink your sweatshirt and enjoy a better fit without compromising its quality or style.

Frequently Asked Questions

Sweatshirts are a popular clothing item that can sometimes fit a bit too loose or big. If you find yourself with a sweatshirt that is too large, you may be wondering how to shrink it to your preferred size. Here are some frequently asked questions about shrinking sweatshirts one size:

1. Can all types of sweatshirts be shrunk?

While many sweatshirts are made from materials that have the potential to shrink, it's important to check the care label and fabric type before attempting to shrink it. Sweatshirts made from natural fibers like cotton or wool are more likely to shrink compared to those made from synthetic materials like polyester. Always read the label to determine if shrinking is a suitable option for your sweatshirt.

If you're unsure about the fabric composition, it's best to consult a professional dry cleaner or tailor who can provide expert advice on how to shrink your sweatshirt safely.

2. What is the most effective method to shrink a sweatshirt?

The most effective method to shrink a sweatshirt is by using heat. Washing the sweatshirt in hot water and then drying it on high heat can help to shrink the fibers. However, keep in mind that excessive heat can damage certain fabrics or cause them to lose their shape. It's important to follow the care instructions and avoid using extremely high temperatures if the fabric is delicate or prone to shrinking excessively.

If you're unsure about the appropriate temperature settings for your sweatshirt, it's best to consult the care label or seek professional advice to avoid any mishaps.

3. Can I shrink a sweatshirt without using heat?

While heat is the most effective method for shrinking sweatshirts, it is possible to achieve some degree of shrinkage without using heat. One alternative method is to wet the sweatshirt, then place it in a tight-fitting bag or wrap it in a towel and leave it overnight. The moisture combined with the pressure from the bag or towel can cause the fibers to contract, resulting in a slight shrinkage.

However, it's important to note that this method may not be as effective as using heat and may not shrink the sweatshirt by a full size. If you're looking for more significant shrinkage, using heat is recommended.

4. Will the shrinkage be permanent?

The degree of shrinkage achieved through methods like heat or wetting and pressure may not always be permanent. The sweatshirt may relax and stretch out slightly with wear and subsequent washes, especially if it's made from a fabric that is prone to stretching.

To maintain the shrunken size, it's important to follow the care instructions, specifically the recommended washing and drying methods. Avoid excessive stretching or washing in hot water, as this can cause the sweatshirt to expand again.

5. Can I shrink a sweatshirt that has already been washed and dried?

It is generally more difficult to shrink a sweatshirt that has already been washed and dried, as the fibers may have already reached their maximum shrinkage potential. However, if the sweatshirt is made from a material that has a high potential for shrinkage, such as cotton, there may still be some room for minor shrinkage.

In such cases, it's recommended to follow the same methods mentioned earlier, such as using heat or wetting and pressure, and monitor the results carefully. Remember that the final outcome may vary depending on the fabric composition and previous washing and drying processes.

So there you have it, a simple and effective way to shrink your sweatshirt by one size. By following these steps, you can achieve a snugger fit without having to spend money on a new sweatshirt.

Remember to always check the fabric content of your sweatshirt before attempting to shrink it, as not all materials respond well to heat or water. It is also important to carefully monitor the shrinking process to prevent any damage or excessive shrinkage.
