As a professional custom clothing supplier, we understand your frustration with ill-fitting shirts. But don’t worry, most cotton T-shirts will shrink to some extent after washing and drying.
In this guide, we will share four effective ways to shrink your t shirts to help you create a perfect fit every time.
What Causes Shrinkage
The main reasons for shrinkage are hot water and high heat from a dryer. This heat makes the stretched cotton fibers go back to their original, shorter length. Cotton blended with polyester or other synthetics does not shrink much at all. The way a shirt is made, like the fiber length and fabric weave, also has a big impact on the final shrinkage.
Cotton clothes can shrink quite a bit. The shrinkage rate can be anywhere from 3% to 20%. Shirts that are not pre-shrunk will shrink the most. This happens when you wash them in hot water and dry them on high heat. A standard cotton T-shirt shrinks about 4.8% in length.

The Boiling Method
Bring a large pot of water to a boil, then turn off the heat. Push your t-shirt down into the water until it is completely submerged. Letting it soak for five to twenty minutes. The longer you leave it in the hot water, the more it will shrink. It can shrink up to 20% of its original size. A ten-minute soak gives you a small change. A twenty-minute soak makes the fit much tighter. After soaking, be careful when you take it out. Squeeze out the extra water, but do not wring it too hard. Lay it flat or hang it up to air-dry. If you need it smaller, you can repeat the steps. This to be the most powerful shrinking method. It’s great for stubborn cotton shirts. You just need to be cautious not to overdo it, as you could damage the material.
Hot Water Wash & High Heat Dry
Put your t-shirt in the washing machine. Wash it using hot water and a high spin cycle. Then, move it directly to the dryer and set it to the highest heat. The hot water and the machine’s movement will cause the cotton fibers to tighten and shrink. This old-school method is effective. I suggest you check the fit after one cycle. You should repeat the process if you need the shirt to be smaller. If you do this too many times, your tee could lose its proper shape.
Steam Shrinking
For a more precise technique, I suggest trying steam shrinking. It’s a fantastic option for delicate cotton or fabric blends. Set a garment steamer to high and hold it about 1–2 inches from the fabric. The heat and steam will relax the cotton fibers. This causes a gentle, focused shrink. The steam method is much gentler than boiling or machine drying. It’s the best way to tighten up just the sleeves, hem, or collar.
Spot Shrinkage
To shrink just one spot, you can use steam iron. Turn on the steam function and apply heat to the area you want to shrink. A small amount of steam is very effective. This helps you avoid shrinking the entire shirt by accident. Be cautious, though. Too much heat in one place for too long can burn or damage the cotton.
Guide to Shrinking Methods
Using the Boiling Method
– Time in Boiling Water: soak it for 5–20 minutes.
– 10 minutes: This causes a minor change, about 3%–5%.
– 20 minutes: This gives a tighter fit and can shrink it by 10% or more.
– Can you repeat it? Yes. I recommend doing another cycle for more shrinkage.
Using Hot Water Wash + High Heat Dry
– Washing at a hot setting, over 60°C/140°F.
– Each cycle: A single cycle shrinks the shirt by 3%–5%. Untreated cotton can shrink more.
– Multiple cycles: You can repeat the cycles to shrink it more. I suggest you watch it closely, as you could ruin the shirt’s shape.
Precautions
Cotton blends with materials like polyester don’t shrink as much. If you want the least amount of shrinkage, I’d choose a blend made for that reason. It’s a good idea to read the care label. It gives you the best washing and drying instructions for that fabric.High heat can cause more than shrinking. It can also make colors fade, make the fabric less soft, and weaken the fibers.
- Using medium heat instead of the highest setting.
- You should check on the T-shirt every 5–10 minutes while it’s in the dryer.
- Take the shirt out as soon as it fits you well. This will stop it from shrinking too much.

FAQ
1.How can I maintain the shape of the T-shirt after stretching it?
After stretching, place heavy objects on the T-shirt while it is air drying to help maintain its shape. For example, you can put canned goods in plastic bags and use them to weigh down the T-shirt.
2.How can I achieve a small amount of shrinkage?
You can use lower temperatures for washing and drying, and check the condition of the T-shirt during the drying process. You can also dry it in the dryer on a warm setting for a short time and then air dry it to achieve a small change in size.
