How to Shrink Clothes: 7 Methods That Work on Any Fabric (2026)

Whether you bought a shirt that runs large, lost weight, or received a gift in the wrong size, knowing how to shrink clothes gives you a practical alternative to returns and alterations. Different fabrics respond to different techniques, so using the wrong method can ruin the garment. This guide covers seven proven shrinking methods, organized by fabric type, with specific temperatures, times, and tips to achieve the right fit without damaging your clothes.

Before You Start: Key Facts

Understanding the science behind fabric shrinkage prevents costly mistakes:

• Heat causes shrinkage — Hot water and high dryer temperatures relax fiber tension, allowing fibers to contract. The hotter the treatment, the more shrinkage you get.
• Agitation accelerates the process — Mechanical action (washing machine tumbling, hand wringing) causes fibers to tangle and compress, increasing shrinkage.
• Shrinkage is mostly irreversible — While some methods exist to stretch clothes back, most shrinkage is permanent. Start with the mildest method and repeat if needed.
• Natural fibers shrink more easily — Cotton, wool, and linen shrink readily. Synthetic fibers like polyester and nylon are heat-resistant and require higher temperatures.
• Typical shrinkage range — Most methods produce 3–8% shrinkage per treatment. A medium shirt (chest 38–40 inches) will lose roughly 1–3 inches in circumference.

Always check the care label before proceeding. If the label says “dry clean only,” take the garment to a tailor for alteration instead.

Method 1: Shrink Cotton Clothes

Cotton is the easiest fabric to shrink because its natural cellulose fibers respond dramatically to heat and moisture.

Washing Machine Method (Mild Shrinkage: 3–5%)

1. Turn the garment inside out to protect the outer surface.
2. Set your washing machine to the hottest water setting (130–150°F).
3. Run a full wash cycle with detergent.
4. Transfer immediately to the dryer on the highest heat setting.
5. Dry completely — removing clothes while still damp reduces shrinkage.

Boiling Method (Aggressive Shrinkage: 5–10%)

1. Bring a large pot of water to a rolling boil.
2. Submerge the garment completely using tongs.
3. Boil for 10–20 minutes, stirring occasionally. Longer boiling = more shrinkage.
4. Remove with tongs and transfer to the dryer on high heat.
5. Check the fit. Repeat if more shrinkage is needed.

Warning: Boiling can fade colors significantly. Only use this method on white or light-colored cotton garments.

Method 2: Shrink Polyester Clothes

Polyester is engineered to resist shrinkage, which makes intentional shrinking challenging but not impossible. Polyester melts at 480°F, so the window between effective shrinking temperature and damage is narrow.

1. Turn the garment inside out.
2. Wash on the hottest cycle your machine offers (130–150°F).
3. Dry on the highest heat setting for a full cycle.
4. Repeat 2–3 times if needed. Polyester typically shrinks only 1–3% per treatment.

Alternative: Iron method — Set your iron to the polyester setting (300°F). Place a damp press cloth over the area you want to shrink and press firmly for 10–15 seconds per section. This allows targeted shrinking of specific areas (e.g., waistband, sleeve length).

Method 3: Shrink Denim Jeans

Raw (unwashed) denim shrinks 3–5% on the first hot wash. Pre-washed jeans are harder to shrink because the manufacturer already removed most of the shrinkage potential.

For Raw Denim

1. Fill a bathtub with hot water (as hot as your tap allows, typically 120–140°F).
2. Submerge the jeans completely and soak for 30–45 minutes.
3. Drain the tub and wring out excess water.
4. Dry on high heat in the dryer until completely dry.

For Pre-Washed Denim

1. Wash on the hottest cycle with the longest duration.
2. Dry on the highest heat setting. Do not remove until fully dry.
3. Repeat if needed. Expect minimal results (1–2%) from pre-washed denim.

If jeans need more than 2 inches of shrinkage, tailoring is more reliable. A tailor can take in the waist ($15–$25), taper the legs ($20–$35), or hem the length ($10–$15).

Method 4: Shrink Wool Garments

Wool shrinks easily — sometimes too easily. The process is called felting, where the scaly fiber surfaces interlock permanently when exposed to heat, moisture, and agitation simultaneously.

Controlled Shrinking (Mild: 3–5%)

1. Fill a basin with warm water (not hot) at approximately 100–110°F.
2. Submerge the garment and let it soak for 10 minutes without agitating.
3. Remove and gently press out excess water. Do not wring or twist.
4. Lay flat on a towel and reshape to the desired dimensions.
5. Allow to air dry completely, reshaping periodically.

Aggressive Shrinking (5–15%)

1. Wash in the washing machine on warm with regular agitation.
2. Dry on medium heat for 15–20 minutes, checking frequently.

Caution: Wool felting is irreversible. Once fibers interlock, the garment cannot be stretched back to its original size. Start with the mild method and escalate only if needed.

Method 5: Shrink Rayon

Rayon is a semi-synthetic fiber derived from wood pulp. It shrinks easily but also distorts easily, making controlled shrinking tricky.

1. Hand wash in warm water (90–100°F) with a small amount of gentle detergent.
2. Do not wring. Press water out gently between towels.
3. Dry on medium-low heat in the dryer for 10–15 minutes.
4. Check fit while slightly damp. Reshape as needed and air dry to finish.

Expected shrinkage: 3–5%. Rayon can lose its drape and develop a rough texture if overheated, so err on the side of lower temperatures.

Method 6: Shrink Linen

Linen shrinks 3–4% on its first hot wash and up to 10% total over multiple washes. Most quality linen garments are pre-washed to minimize this, but some shrinkage potential usually remains.

1. Wash in hot water (130–140°F) on a normal cycle.
2. Dry on high heat until completely dry.
3. Check fit and repeat if needed.

Linen wrinkles aggressively after heat treatment. Iron on the linen setting while slightly damp to smooth the fabric and lock in the new dimensions.

Method 7: Shrink Fabric Blends

Blended fabrics (like 60/40 cotton-polyester) shrink at a rate determined by the dominant fiber and the blend ratio. Use the method for the more delicate fiber in the blend:

How to Unshrink Clothes (If You Went Too Far)

If a garment shrunk more than intended, try the baby shampoo method:

1. Fill a basin with lukewarm water and add 1 tablespoon of baby shampoo or hair conditioner per quart of water.
2. Submerge the garment and soak for 30 minutes. The conditioner relaxes the fibers.
3. Remove without rinsing. Gently squeeze out excess water.
4. Lay the garment flat on a dry towel.
5. Slowly and gently stretch the garment to its desired dimensions, working section by section.
6. Pin or weight the edges to maintain the stretched shape while drying.
7. Allow to air dry completely.

This method works best on cotton and wool. Success rate is approximately 60–70% for mild over-shrinkage and 20–30% for severe cases. It does not work on felted wool.

Frequently Asked Questions

How much will clothes shrink in the dryer?

Most natural fiber garments shrink 3–5% in a hot dryer cycle. A medium T-shirt with a 40-inch chest will lose about 1.2–2 inches in circumference. Pre-shrunk garments will shrink less (1–2%), and synthetic fabrics will shrink minimally (0.5–1%).

Can you shrink clothes that are too big by 2 sizes?

Dropping two full sizes requires approximately 10–15% shrinkage, which is only achievable with untreated natural fibers like raw cotton or wool through aggressive methods (boiling or felting). For most garments, tailoring is a more reliable and controllable approach for reducing two or more sizes.

Will shrinking clothes ruin the print or color?

Hot water and high dryer heat can fade colors, especially in dark garments. Screen-printed graphics may crack or peel at temperatures above 150°F. Turn printed garments inside out and use the washing machine method (not boiling) to minimize damage.

Can you shrink just one part of a garment?

Yes. Use the iron method: dampen the specific area (sleeve, waist, collar), cover with a press cloth, and iron on medium-high heat for 10–15 seconds per section. This allows targeted shrinkage without affecting the rest of the garment.

How do I shrink a hoodie without shrinking the drawstrings?

Remove the drawstrings before washing. If they are sewn in, tie them loosely outside the hoodie and clip with a safety pin to the exterior. Wash and dry the hoodie using the cotton method. Rethread the drawstrings afterward. Polyester drawstrings do not shrink noticeably regardless.

Is it better to shrink clothes or get them tailored?

For adjustments of 1 inch or less, shrinking is cheaper and faster. For adjustments larger than 1 inch, tailoring gives you precise control over fit and costs $10–$35 for most basic alterations. Tailoring is always the better choice for structured garments like blazers and dress pants.
