Whether your old favorite sweater is all stretched out, or you bought one that’s too big and shapeless, knowing how to shrink it will make it fit you perfectly. You can shrink a wool, cashmere, angora, or mohair sweater in the washer and dryer, reshape a wet wool sweater with your hands, boil and iron a cotton sweater, or tailor any sweater to fit you. You may find that washing and scrunching works best for stretched out sweaters, and tailoring is a better option for garments that are too large.
Quick Guide: Making a Sweater or Jumper Smaller
To shrink a sweater or jumper, wash it at a high temperature on a short cycle (about 10 minutes). Then, dry the sweater on medium heat for 25 minutes, checking its size every 6 minutes to make sure it doesn’t shrink too much. This method works for wool, cashmere, angora, and mohair sweaters.
Steps
-
Wash your sweater on a hot cycle. This can work on wool, cashmere, angora, and mohair sweaters. You can also wash the sweater in hot water, but the cycle should be much shorter than a full cycle. Time it for 10 minutes and check on it every few minutes. [1] X Expert Source Susan Stocker
Cleaning Guru Expert Interview. 8 November 2019.- You can put the sweater in a pillowcase to prevent the fibers from snagging in the machine.
- Another way to fight fading is to turn it inside out.
-
Dry the sweater on low heat for 25 minutes, checking it every 6 minutes. The heat will make the fibers tighten up, which causes the garment to shrink. To avoid shrinking your sweater too much, check on it every 6 minutes. [2] X Expert Source Susan Stocker

Try the sweater on but put it in the dryer again if it’s still too big. Make sure it fits and didn’t shrink too much. If it’s too big, put it in the dryer again for 25 minutes and check on it every 6 minutes. If you were checking on it regularly, it shouldn’t have gotten too small. Putting it in the dryer for 25 minutes with other garments will shrink the sweater down 1 size. [4] X Research source
- Look in the mirror at all angles to see if the sweater fits well.
- Observe if it feels too tight or is still a little loose where you want it to be form-fitting.
Kate Sekules, Veteran Fashion Journalist & Expert on Clothing RepairBefore discarding a favorite sweater now oversized, try strategic shrinking techniques first. Carefully wash in hot water, reshaping while damp before high heat drying to tighten fibers. Handle with care, assessing as you go to preserve integrity of knit material. Gradually shrinking until the desired fit is achieved, keeping in mind that overdoing it may cause uneven texture. Tightening a loose sweater too aggressively weakens its structure.

Fill a sink with cool water and bleach-free detergent. This can work for a stretched out wool sweater. Add 1 tablespoon (15 mL) of mild, bleach-free detergent to the water. You can also use detergents made for washing wool. Mix the detergent in the water with your hand. [5] X Research source
-
Blot the sweater with a towel to remove excess water. To blot it, press the towel against the sweater to squeeze the extra water out. You can also push your sweater against the wall of the sink to squeeze excess water out. [8] X Research source
- Alternatively, roll the sweater up in the towel like a burrito to remove more water. Just be sure to avoid wringing it out, as this can ruin the fabric.
-
Manipulate the fabric with your hands to shrink areas of the sweater. Grip the sweater with your hands to gently squish together parts of the fabric that you want to shrink. Place your hands firmly on the sweater, and use your fingers to push the material inward. Do this with the whole garment if needed, or just in some areas such as the bust or waist. [9] X Research source
- Put a towel down to soak up excess water from the sweater.
- Place the sweater on a flat surface while you reshape it.
-
Let your sweater air dry on a flat surface. Ideally, you should leave it on the surface where you reshaped it, so you don’t disturb the work you did. You can put it on your bed, a table, a counter, or any flat surface where it won’t be disturbed. So, keep it away from pets, if you have any.
- Keep your sweater out of direct heat and sunlight to prevent too much shrinkage.

Put the sweater in a pot of boiling water for 5 minutes. This works well for cotton fabrics . The pot should be tall enough to fill it with water while leaving room for the sweater. Let the water come to a boil, add the sweater, then let it boil for 5 minutes. [10] X Research source
- Add 1 c (240 mL) of white vinegar to the water to prevent the colors from fading.
- The garment should be 100% cotton to shrink it with boiling water and an iron.
- This may not work for a preshrunk garment.
-
Remove the sweater from the pot and absorb excess water with a towel. Blot the wet sweater until it’s no longer dripping wet. You can also roll up the sweater inside the towel to squeeze the water out. [11] X Research source
-
Iron the sweater on high heat for 5 minutes. High heat is ideal for a cotton sweater you’re trying to shrink. Place it flat on the ironing board and cover it with a cloth, such as a towel to protect it from heat damage. [12] X Research source
- If your iron has a steam function, you could use that by filling the iron with water and letting it warm up before ironing the garment.

Put your sweater on and pinch the excess fabric with your fingers. Pull out the sides of the sweater to see how large it is and decide how closely you want it to fit your form. By pinching the fabric, you’ll determine where to start your seam when you turn the sweater inside out. [13] X Research source
-
Turn your sweater inside out to make the side seam. A sweater made of any material can be altered. Knit sweaters don’t have seam allowances but turning one inside out to find the seam is where you start when altering it. This inside seam is the one you’ll be taking in when altering the sweater. [14] X Research source
- Make sure the sweater is pressed completely flat and symmetrical on a table, so it’s not altered crooked.
- Use chalk to draw a line on the sweater where you will be making the seams. This will make it easier to remember where to put the pins. [15] X Research source
-
Make a seam allowance using pins. Take in about 1 to 1 ⁄ 2 in (2.5 to 1.3 cm) on the side of the sweater, depending on how big it is. Starting at the armpit, or whichever part is too big, stick several pins along each side of the sweater to mark where the seam will be. [16] X Research source
- To make an accurate seam allowance, use the seam guide on your sewing machine. Most sewing machines come with 1 ⁄ 4 inch (0.64 cm) seam guide.
-
Take in 1 to 1 ⁄ 2 in (2.5 to 1.3 cm) on each side of the sweater. Measure it with a tape measure and put pins where you want the seam to be. When you sew the seam, keep the pins in place to sew it evenly.
-
Sew along the edges of the sweater to make the seam. Set the sewing machine to make a dart or zig-zag stitch for a neat and flexible seam allowance on the sweater. Sew along the edge where you stuck the pins as placeholders. Remove the pins as you sew. [17] X Research source
- Stop sewing just before the ribbing or hem of your sweater to prevent an odd flip out of fabric at the bottom.
-
Sew a seam on the other side of the sweater. Make sure you measure both sides equally. Measure the seam allowance and mark the new seam with chalk. Line up the pins to hold fabric in place. Sew with a dart or zigzag stitch on the sewing machine. [18] X Research source
-
Flip the sweater right side out and try it on. Hold the sweater up in front of you to see if it looks even and try it on for the fit. If the sweater has buttons down the front, button it up to make sure it fits all the way around your torso. [19] X Research source
- Look at yourself wearing the sweater in the mirror to see if it looks as though it fits right. If not, repeat the process.

QuestionWhat are the easiest fabrics to shrink?Susan Stocker runs and owns Susan’s Green Cleaning, the #1 Green Cleaning Company in Seattle. She is well known in the region for outstanding customer service protocols — winning the 2017 Better Business Torch Award for Ethics & Integrity —and her energetic support of green cleaning practices.Wool is probably the easiest. I've seen some absolutely huge wool sweaters shrink down to infant-sized with a single hot water wash. Cotton is fairly easy to shrink down about 20% as well. Synthetic fibers are probably the hardest to shrink.

Tips
- Wetting and scrunching a sweater is a better way to get a stretched-out sweater back to its original shape. Tailoring if best for sweaters you buy that are too large. [20] X Research sourceThanks
- To avoid bumps and stretching in a wet sweater, don’t hang it to dry. Hangers will cause shoulder bumps, and the weight of the water in the fabric will pull the sweater downwards causing it to stretch.Thanks

The easiest way to shrink a wool, cashmere, angora, or mohair sweater is by washing it in hot water for about 10 minutes. To keep the sweater’s fibers from snagging in your washing machine, put it in a pillowcase before washing. When you dry your sweater, put it in the dryer on low heat for 25 minutes. Since the heat will make the fibers tighten up, check on it every 6 minutes to keep it from shrinking too much. For cotton fabrics, put your sweater in a pot of boiling water for 5 minutes, then take it out and blot any excess water with a towel. Once your sweater is slightly damp, iron it on high heat for 5 minutes. For more tips, like how to reshape your sweater so it fits better, read on!
