Shrinking a t shirt can be done in a number of different ways, with the two most effective methods being the washer and dryer, as well as using boiling water.
Most T-shirts are made from either 100% cotton, a cotton blend, a polyester blend, or a cotton poly blend. Shirts made from cotton fiber will shrink more than shirts made from polyester, as polyester is a synthetic fabric that has been specially designed not to shrink.
To shrink a T-shirt, use the washing machine on the highest heat setting possible, and when that is finished, move the shirt over to the dryer and run the cycle on tumble dry high. Not tumble dry low or tumble dry medium, these will not be hot enough,

How To Shrink A T-Shirt
There are several methods to choose from when attempting to shrink your t-shirt.

Alternatively you can make your t-shirt smaller by taking it into a tailors. If there is no tailor near you, try your local dry cleaner.
100% Cotton t-shirts and cotton blend t-shirts will shrink more than t-shirts made out of polyester. Polyester has been specifically designed not to shrink or wrinkle, and is also non-resistant to heat, which means that you shouldn’t attempt to shrink your polyester clothing too frequently. Polyester mixed with cotton, such as a 60/40 poly cotton blend, will shrink to some degree, but not as much as a 100% cotton t-shirt.

How to shrink a t-shirt: quick tips
- Machine wash the t-shirt in hot water. Hot water can cause the fibers to contract, leading to some shrinkage.
- After washing, tumble dry the t-shirt on high heat. The heat from the dryer can further aid in shrinking the fabric.
- When removing the t-shirt from the dryer, avoid stretching it while it’s still hot. This can prevent it from reverting to its original size.
- If the desired shrinkage is not achieved in one cycle, repeat the washing and drying process until you achieve the desired fit. However, be cautious not to over-shrink the shirt.
- Some fabrics, like 100% cotton, are more prone to shrinking than others. Keep this in mind when attempting to shrink a t-shirt and consider the material’s natural characteristics.
