Do you have a pair of jeans that you love, but are too short? Did you buy your child a pair of jeans only to have your child hit a growth spurt? Fortunately, there are several ways to lengthen a pair of jeans. This article will show you several ways in which you can make your jeans longer.

Method 1
Method 1 of 4:

Using Water

  1. This method is simple, but it requires some drying time. It will help restore your jeans to their original length (or close to it). It is perfect for those jeans that have shrunk in the was. Here's a list of what you will need:
    • Jeans
    • Sink, tub, or bucket
    • Lukewarm water
    • Baby shampoo
    • 2 towels
    • Fan (optional)
  2. You will need about a cap-ful of the shampoo. The shampoo will help soften the fabric and make it easier to work with. [1]
    • If you can't find a sink large enough to fit your jeans, you can also use a bucket or tub.

  3. Gently swish the jeans around from time to time so that the soapy water gets into the fibers. If the jeans won't stay under the water, you can try weighing them down with a heavy jar.
  4. Don't rinse, twist, or wring the jeans.
  5. The towel needs to be long enough to fit your jeans. Place the jeans on top of the towel. Start rolling the jeans and the towel at the same time. You can start from either the top or the bottom. It doesn't matter which side; you are just getting the excess water out.
  6. Unroll the towel and take the jeans off. The jeans should still be damp, but not dripping wet.
  7. The towel needs to be long enough to fit your jeans.
  8. Start tugging from anywhere below the knee in short, little jerks. Work your way down towards the cuffs. Be sure that you tug from both sides of the pant leg (the inseam and the outer seam) so that the leg will be even at the bottom.
    • If you're using flare jeans, pull by where the flare starts.
  9. 9
    Allow the jeans to dry. If you want, you can set a fan down next to them. This will speed up the drying process. [2]

Method 2 of 4:

Adding a Trim

  1. This method is ideal for those pairs of jeans that are just a little bit too short. The trim will help your jeans look longer. It will also act as an embellishment or decoration. Depending on how wide your trim is, you can make your jeans quite a bit longer. Here's a list of what you will need:
    • Jeans
    • Tape measure
    • Trim (lace, ribbon, ruffle, etc)
    • Scissors
    • Thread
    • Sewing machine or sharp needle
    • Sewing pins
  2. You will be sewing the trim to the bottom of the jean cuff using a ½ inch (1.27 centimeters) seam allowance, so make sure that your trim is wide enough. Here are some things you can use as a trim:
    • Crocheted lace
    • Regular, scalloped-edge lace
    • Embroidered ribbon
    • Ruffled fabric
  3. Make sure you are measuring inside the pant leg. Jeans are thick, especially along the bottom cuff. Place a tape measure inside the leg and measure all the way around the bottom hem. Start and end at the inseam.
  4. If the fabric is very delicate and frays a lot, you can seal off the ends with some super glue, fabric glue, clear nail polish, or fray check.
  5. Make sure that you are sewing the right side together. You can sew by hand using a running stitch, or on a sewing machine. Tie the ends off into a tight knot and snip off any excess thread.
  6. If you want, you can press the inside seam flat with an iron.
  7. The top edge of your trim and the bottom cuff should be overlapping by no more than ½ inch (1.27 centimeters).
  8. Make sure that you are using a thread color that matches your jeans. When you are done, remove the pins and tie the ends into tight knots. Snip the excess thread off.
    • You can sew the trim on using a sewing machine or a sharp needle and thread.
  9. Your jeans are now a little bit longer and fancier than before.

Method 3 of 4:

Adjusting the Hem

  1. This method relies on the fabric tucked away inside the hem of your jeans. Depending on how much fabric is tucked away, this method can only make your jeans longer by an inch (2.54 centimeters) or so. As such, this method is better for those jeans that only need to be a little bit longer. [3] Here's a list of what you'll need:
    • Jeans
    • Seam ripper
    • Tape measure
    • Scissors
    • Thread
    • Sewing machine
    • Cotton fabric
    • Sewing pins
  2. [4] You will notice that there are fold lines along the bottom edge. If you want, you can iron them out, but keep in mind that they will never really go away. [5]
  3. Take your tape measure, and measure across the bottom of the pant leg, from inseam to outer seam.
  4. Each rectangle needs to be about 2.5 inches (6.35 centimeters) tall and 1 inch (2.54 centimeters) longer than the bottom of your pant leg. This will be enough to hem one pant leg.
    • You can use any color or pattern you want. You can match the fabric to your jeans, or use a contrasting color.
    • Lighter fabric, such as cotton, will be easier to sew with.
  5. Pin the right sides together. Sew along both of the narrow ends using a ½ inch (1.27 centimeters) seam allowance. Do not sew along the long edges. This will be your lining.
  6. The top edge of the lining needs to align with the bottom edge of the pant leg. Make sure that the side seams of the lining are aligned with the seams on the pant leg. Pin everything in place.
  7. Slide the pant leg onto the sewing machine arm. You may notice that your jeans have several fold lines. Sew along the fold line closest to the raw edge. Sew all the way around the bottom of the pant leg, turning the leg as you go. Tie the ends of the thread off into tight knots and snip any excess thread off.
    • If you can't find a fold line, then use a ½ inch (1.27 centimeters) seam allowance.
  8. Iron the hem towards the top of the pants, away from the lining. Keep the pant leg inside out.
  9. Pin and iron the hem flat, then remove the pins. This will be the hem, so you won't see any raw edges inside your pant leg.
  10. The seam between the lining and the jean fabric is now the bottom of your pants. Press the seam with an iron.
  11. Slide the pant leg back onto the sewing machine. Try to sew as close to the folded edge of the lining as possible. When you are done, tie the threads into tight knots and snip off any excess.
  12. Your jeans are now a little bit longer than before. The inside is also neatly hemmed. [6] The cuffs will still have fold lines. Over time, the lines will fade, but they will never completely disappear. They will be less noticeable light lighter-colored jeans, however. [7]

Method 4 of 4:

Adding a Fabric Cuff

PDF download Download Article
  1. This method is great for those pairs of jeans that need to be made a lot longer. Because of the wide, colorful cuff you'll be making, this method is great for children's jeans. Here's what you'll need:
    • Jeans
    • Tape measure
    • Scissors
    • Thread
    • Sewing machine
    • Fabric
    • Sewing pins
  2. Don't worry, your jeans will be longer by the end of this tutorial. The bottom hems adds a lot of bulk. It will be easier to sew without it.
  3. You will be sewing a fabric band or cuff to make the jeans longer. First, however, you will need to draft the pattern for your cuff. Here is how to figure out the measurements for your cuff:
    • Measure around the cut edge of the pant leg (the circumference). Add 1 inch (2.54 centimeters). You will need this for your seam allowance.
    • Decide how wide you want the band to be. Multiply that number by 2 (you will be folding the fabric in half later) and add 1 inch (2.54 centimeters) for the seam allowance.
  4. You will end up with something that looks like a rectangle. You can use any fabric you want, but a lightweight fabric (such as cotton) may be easier to sew with than a heavyweight fabric (such as canvas). Choose something with a contrasting color. You can even pick something out with a fun pattern.
  5. Make sure that you are sewing the right sides together. Use a ½ inch (1.27) seam allowance. You will end up with a squat tube.
  6. You should now see the right sides of the fabric on the outside and on the inside of the tube.
  7. Align the cut edge of the cuff with the cut edge of the pant leg. Rotate the cuff so that the seam is aligned with the inseam of the jeans. Pin everything in place.
  8. Slip the pant leg onto the sewing machine and sew along the raw/cut edge. Rotate the pant leg as you go so that it does not get tangled. Snip off any excess thread and tie the ends into tight knots.
  9. Press the hem against the jean fabric and away from the cuff.
  10. Slip the pant leg back onto the sewing machine arm and sew the hem down. Try to get as close to the seam as possible. Be sure to rotate the pant leg as you go so that it does not get tangled. When you are done, tie the threads off into tight knots and snip off any excess.
  11. Your pant legs will now be much longer. The bright band of color along the bottom hem will add some contrast and flair. [8]

    Expert Answer
    Possibly! Just keep in mind that jeans typically have a small hem on the bottom, so the tailor won't be able to do much unless the garment has a very wide hem.

    What if you don't have any baby shampoo?
    Community Answer
    Unfortunately, there is no other thing you can use. Fortunately, baby shampoo can be found in most stores and is quite cheap.

      Tips

      • Keep in mind that if you have holes in your jeans, excessive pulling will most likely rip the holes even bigger.

      • If you are using the water method and jeans have any detailing (like rhinestones or embroidery) then pull either an inch above or below the detailing.

      • Thinner fabrics and trims are easier to sew than heavier fabrics and trims. If you are going to add some trim or a cuff, choose a lighter fabric, such as cotton, instead of a heavier one, such as canvas.

      Warnings

      • You may have to repeat the water method a few times until you get the length you want. Let the jeans dry before you try the method again.

      • If your jeans have holes in them and you are using the water method, be very careful. The tugging can cause the holes to rip further.
