A T-shirt that’s too big can feel uncomfortable and unflattering. Whether you’ve accidentally bought the wrong size or your favorite tee has stretched out over time, shrinking it can help you achieve the perfect fit. Fortunately, there are several simple and effective ways to shrink a T-shirt at home.
This guide will walk you through different methods to shrink a T-shirt, from using hot water and a dryer to steaming and ironing techniques. We’ll also discuss how fabric type affects shrinkage and how to prevent over-shrinking.
Will Your T-Shirt Shrink?
Before trying to shrink your T-shirt, it’s important to check its fabric composition. Different materials react differently to heat and water.
If your T-shirt is made of 100% cotton, you’ll likely see significant shrinkage, as cotton fibers contract when exposed to heat. Cotton blends will shrink as well, but to a lesser extent depending on the percentage of cotton in the fabric. Polyester and synthetic fabrics, on the other hand, are designed to resist shrinkage and will only reduce slightly in size. Wool and linen blends can shrink, but they may also warp, so they require extra care.
If your T-shirt is made of natural fibers, you’ll likely see significant shrinkage, while synthetic fabrics may only reduce slightly in size. If you are also looking to upgrade your everyday wardrobe essentials, check out Private Structure—a perfect blend of comfort and style.
Hot Water Wash & High Heat Dry
One of the easiest ways to shrink a T-shirt is by using your washing machine and dryer. This method works well for cotton and cotton-blend shirts.
Start by turning your shirt inside out to prevent excessive fading and protect any printed designs. Set your washing machine to the highest water temperature and run a full cycle. Hot water causes the fibers to contract, leading to shrinkage. Once the wash cycle is complete, transfer the T-shirt to the dryer immediately while it’s still wet. Use the highest heat setting on the dryer, as this will further shrink the fibers.
Check the shirt every 10–15 minutes to ensure it doesn’t shrink too much. If the shirt isn’t small enough after one cycle, you can repeat the process. This method can shrink a cotton T-shirt by one to two sizes.

Boiling Water Soak
If you need more significant shrinkage, boiling water is a great option. This method is best for cotton T-shirts that need a drastic size reduction.
To use this method, boil a large pot of water and remove it from heat once it reaches a rolling boil. Submerge the T-shirt completely in the water and let it soak for five to ten minutes. The longer you leave it in, the more it will shrink. If you only want slight shrinkage, soak it for a shorter time.
After removing the shirt from the water, allow it to cool slightly before placing it in the dryer on high heat. This final step locks in the shrinkage and ensures that the fibers remain contracted. The boiling water method can reduce a shirt by two sizes or more, depending on how long it is soaked and dried.
Steam Ironing for Targeted Shrinking
If you only need to shrink certain areas of your T-shirt, such as the sleeves, neckline, or waist, steam ironing is an effective technique.
Begin by dampening the T-shirt with a spray bottle filled with warm water. Lightly mist the areas that need shrinking, making sure not to soak the fabric completely. Set your iron to the highest steam setting and apply steam to the damp areas, using circular motions to evenly distribute the heat. Focus on areas like the collar, sleeves, or sides if you want to adjust the shape of the shirt.
Once you’ve finished steaming, let the shirt dry naturally. As it dries, the fibers will tighten, locking in the shrinkage. This method is ideal for making minor adjustments without shrinking the entire shirt.
The Hair Dryer Method
A hairdryer is a great tool for shrinking a T-shirt quickly, especially if you don’t want to risk over-shrinking in a washing machine or dryer.
To start, dampen the T-shirt with warm water, focusing on areas where you need shrinkage. Set your hairdryer to high heat and hold it about six inches away from the fabric. Move the dryer evenly over the shirt, making sure to dry each section thoroughly.
Once the shirt is completely dry, check the fit. If it hasn’t shrunk enough, you can repeat the process. The hairdryer method allows you to control the amount of shrinkage and is ideal for quick fixes.
How to Prevent Over-Shrinking
While shrinking a T-shirt can be useful, overdoing it can make your shirt too tight or misshapen. The best way to prevent excessive shrinkage is to check the T-shirt frequently during the washing and drying process. If you want only mild shrinkage, consider using medium heat instead of high heat.
Another way to prevent over-shrinking is to shrink the T-shirt in stages rather than all at once. Wash and dry the shirt once, then check the fit before deciding if another cycle is necessary. If you accidentally shrink your shirt too much, try stretching it while it’s still damp to regain some size.
Does Shrinking a T-Shirt Damage the Fabric?
Shrinking can put stress on the fibers, especially if high heat is used multiple times. Over time, repeated shrinking may cause the fabric to weaken, lose its softness, or develop a rough texture. If you want to minimize fabric damage, avoid excessive heat and always check the T-shirt’s care label before attempting any shrinking method.
What If Your T-Shirt Doesn’t Shrink?
If your T-shirt is made of polyester, spandex, or other synthetic materials, it may not shrink as much as cotton. In this case, you can try repeating the shrinking process multiple times to see if it makes a difference. If your shirt still doesn’t shrink, consider taking it to a tailor for professional alterations. Another option is to layer it with another piece of clothing for a better fit instead of trying to shrink it.
Final Thoughts
Shrinking a T-shirt is a simple process that can help you achieve a better fit without professional alterations. Whether you use hot water, a dryer, steam ironing, or a hairdryer, each method can effectively reduce the size of your shirt based on your needs. Be sure to check the fabric type and monitor the process to prevent over-shrinking or damaging the material. If your T-shirt doesn’t shrink enough, repeating the process can help.
