Key Points to Remember
To effectively shrink a garment in the washing machine, it is recommended to use hot water and select a program with a high temperature. The fabric of the garment, whether cotton or synthetic, also determines the technique. Monitor the process closely and avoid excessive shrinking so as not to distort the garment.

Understanding how garment shrinkage works
The shrinkage of a garment is a complex process that depends on many factors. To achieve the best results, it is essential to understand the role of temperature and the washing program.
The role of temperature in garment shrinkage
Hot water is crucial for effectively shrinking a garment, as it allows the fibers of the fabric to tighten. A high temperature causes the fibers to contract.
Warm water can slightly shrink a garment, but the effect will be minimal. For optimal shrinkage, a temperature between 40 and 60°C is required.
Choosing the right wash cycle to shrink a garment
Not all wash cycles are equally effective at shrinking a garment. Delicate and quick cold cycles will not shrink effectively.
Choose a cotton or synthetics cycle at a minimum of 40°C. Agitation and spinning will also contribute to shrinkage.
At G-Heat®, we are obsessed with offering you ultra-soft garments that fit your shape perfectly. However, we know that sometimes the ideal size is not available. Fortunately, there are simple techniques for readjusting your favorite clothes.

Types of fabrics and how they react to shrinkage
Depending on whether they are natural or synthetic fibers, fabrics do not react the same way to shrinkage.
Natural vs. synthetic fabrics
Fabrics made from natural fibers, such as cotton and wool, shrink better than synthetics. Polyester and nylon shrink very little.
Linen and cotton are very sensitive to heat and shrink easily. Wool also shrinks, but less so.
How each type of fabric shrinks
Cotton shrinks evenly when heated. Wool tends to felt and become less uniform.
Synthetic fabrics such as polyester mainly shrink in length. Nylon does not change much.
What temperature should you use to shrink clothing?
The ideal temperature depends on the fabric, but is generally between 40°C and 60°C.
How do you shrink pants in the washing machine?
To shrink pants, wash them at a maximum temperature of 60°C. Use a cotton cycle with an intensive spin to shrink the waist and length.
How to shrink a sweater: steps to follow
Wash your wool sweater at 40°C on a wool cycle with a short spin cycle. Avoid shrinking it too much to keep its shape.
How to shrink a T-shirt?
Cotton T-shirts shrink well. Wash at 60°C on a cotton cycle, then dry in the open air for maximum shrinkage.
The technique for shrinking jeans in the washing machine
Wash your jeans at 60°C on a intensive cycle with a strong spin. For best results, wash them inside out. Avoid using the dryer.
Mistakes to avoid so as not to distort a garment by shrinking it
- Not choosing the right temperature: too low and it won't shrink, too high and you risk damaging it.
- Shrinking a delicate garment too much, which can distort it.
- Washing a pre-shrunk garment, which will not withstand a second treatment.
- Drying a garment for too long in a tumble dryer, at the risk of shrinking it excessively.
The tumble dryer alternative for shrinking a garment
The tumble dryer can also be used to shrink garments, thanks to the heat it produces. This technique is effective on cotton.
Set the temperature to hot or very hot. The effect will be gradual: check the size regularly to avoid over-shrinking.
The role of sewing in readjusting the size of a garment
It is possible to adjust a garment that is too large by altering the seams. This technique allows for targeted and precise shrinking.
Take the necessary measurements and consult a tailor. This is also a good solution for delicate clothes that cannot withstand the machine.
Tips for caring for your clothes after shrinking them
After the shrinking process, it is recommended to:
- Dry clothes thoroughly on a flat surface to maintain their shape.
- Iron if necessary to restore a smooth appearance.
- Wash inside out on a delicate cycle to preserve the shrinkage.
- Always check the labels on clothes for care instructions.
Conclusion
It is possible to shrink a garment in the washing machine by choosing the right settings. Hot water, a suitable temperature, and an intensive spin cycle will reduce the size.
The techniques differ slightly depending on the fabric, whether cotton, wool, or synthetic. By following a few rules, you can give your oversized clothes a second life!
Follow our step-by-step guide to successfully shrink your clothes. Feel free to experiment on clothes you don't wear often before trying it on your favorite T-shirt. With a little practice, you'll soon become an expert in DIY shrinking!

FAQ
What temperature should I use to shrink a garment?
Between 40°C and 60°C depending on the fabric. Cotton and synthetics can withstand 60°C, while for wool it is better to stay around 40°C.
How do you shrink a garment by one size?
Wash at 60°C on a heavy-duty cycle with a strong spin. For best results, wash the garment inside out. Avoid using a dryer.
How do you shrink clothes that are too big?
Wash on a cotton or synthetics cycle at a minimum of 60°C. Choose a program with an intensive spin cycle to maximize shrinkage.
What temperature causes clothing to shrink?
A high temperature, between 40 and 60°C, will allow the clothing to shrink well. Ideally, use a cotton or synthetics program at 60°C.
What temperature should I use to shrink cotton?
Cotton shrinks very well at 60°C. You can wash your cotton clothes at this maximum temperature to achieve optimal size reduction.
How can you shrink jeans without a dryer?
Wash your jeans at 60°C in the washing machine on a heavy-duty cycle with a strong spin cycle. Then hang them up to dry in the open air. The hot water and agitation will be enough to shrink them.
How can I shrink a garment by half a size?
Wash at 60°C on a heavy-duty cycle with a strong spin to maximize shrinkage. You can add a cup of vinegar for extra effect. Check regularly to avoid distortion.
How can I avoid unpleasant surprises?
Follow the labels and precautions provided by the manufacturers. Test on a garment you no longer wear before washing one that is important to you.
What is the most effective method?
Ideally, use a quick cycle at 60°C with a high spin cycle. You can then place the laundry in the sun to maximize shrinkage.
How can I fix a wool sweater that has shrunk too much?
Gently stretch it in both directions. You can also wet it and dry it flat, stretching the fabric while it dries. As a last resort, soak it in a large pot of hot water.
