As Kids grow up, pants start to run short. I revamped my girl’s pants and it turned out so cute. I saved them and gave them a second chance.

DIY Lengthen Pants to Extend Their Life

Revamping kid’s pants is super easy, have you noticed how much I love easy crafts??? LOL. Well, I do love easy projects, and I love to see final results quickly LOL

I also love having time to do other things! This took a couple of hours even to take pictures. Then as it is my tradition, we had lots of fun in the outdoor photo session. I used for this a very special pair of pants {sentimental meaning} with an easy trick that also ends up revamping it.

How to Lengthen Pants That Are Too Short

Some pants are easier to revamp than others. When you don’t have enough hem to let down, you can lengthen your pants by adding a fabric cuff to the bottom.

Dig through your fabric stash for a piece of fabric, ruffle or lace that you can sew onto the bottom of each leg to create a cuff: This is a fun and stylish option and can work for jeans or for dress pants.

Supplies:

  • Pants

The Pants’ Cuff

1. The first thing is to measure the length of the cuff.

2. Put the pant on your girl and measure how much more length you need to add to the bottom of the pant leg.

3. If for example, you need 1,5 inches you add 1 more inch and then double it.

4. So it would be 1,5 + 1 = 2,5 x 2 = 5 inches.

5. Then measure the width of the pant leg at the hem level.

6. Double that measurement and add ½ inch seam allowance on each end.

7. With wrong sides together, fold each cuff along its width, bringing long edges together. Press, then open up again.

8. For the bottom fabric, Turn the long sides under ½ inch and then iron it.

Crafting Tips

This technique is also a really nice way to add some interest or accent to a pair of plain pants. Even if the pants don’t need to be lengthened, sew exactly as above and turn up the cuffs so that when your child grows you can simply fold them down for extra length.

If the pants you are lengthening are jeans, you can use a different shade of denim fabric to make the cuffs.

You can make the cuff with cute ruffles instead of this technique. Or even creating different layerings of fabrics to create some crazy effect.

Frequently Asked Questions

Can you extend the length of the pants?

When your pants don’t have enough hem to let down, you can lengthen them by adding a fabric cuff. Use a piece of fabric, a ruffle, or some lace to create a cuff on the bottom of your jeans or your dress pants to add a stylish touch.

How do you wear pants that are too short?

If your jeans or pants are a little too short, cuff them and no one will ever know. Roll your pants’ hem up and use them as Capri. Or cut them a little below your knee and turn them into Capris.

How can I make my jeans longer without sewing?

You can follow the same instructions but using fusible tape – Double-sided iron-on fabric adhesive. If what you need to lengthen isn’t too much, you can just use a seam ripper to rip out the hem of each pant cuff then iron it well and leave the edges raw.
