How to Hem Petite Jeans and Keep the Original Hem?
Every petite woman knows the ritual. You find the perfect pair of jeans. The wash is right. The rise is right. The fit through the hips is spot on. Then you look down and three inches of denim are pooling over your shoes. If you knew how to hem jeans petite, you would fix them tonight. Instead, they sit in the “take to tailor” pile for weeks.
A tailor charges $50 or more to shorten jeans and keep the original hem. Multiply that across every pair you own. This guide teaches you the “original hem” method. You fold the excess inside the leg and sew one straight line. The factory-finished bottom edge stays. The faded stitching stays.
The worn-in look stays. Your first attempt might take closer to an hour. That is still $50 back in your pocket. Grab a sewing machine, a denim needle, and your too-long jeans.
Step 1: Wash and dry your jeans at least twice before you start

Denim shrinks. Sometimes by 1 to 2 full inches in length after the first wash cycle. If you hem first and wash later, your new length becomes too short to fix. Run the jeans through a full wash and dry at least twice using the same temperature settings you normally would. Hot water and high heat pull out the most shrinkage. Once the jeans stop getting shorter between washes, they are ready. Not before.
Step 2: Put on the jeans with your everyday shoes and mark the new length

Two pairs of shoes, two different hem lengths. Sneakers and ankle boots land the bottom of the jeans at completely different spots on your foot. Pick the shoes you wear most with this pair. Put the jeans on and stand in front of a full-length mirror.

Fold each leg up to where you want the finished hem to fall. For most petite frames, that means right at the top of the shoe or about half an inch above the floor. Have someone place a pin at the crease on each leg. If you are alone, use chalk to mark the fold line on the inside of the fabric.

- Put on the jeans with shoes and mark the new length
- Turn the jeans inside out and lay them flat
- Fold the bottom up so the original hem sits at your mark
- Pin the fold in place around each leg
- Thread your machine with a denim needle and matching thread
- Sew a straight stitch close to the fold around each leg
- Press the new seam flat with a hot iron
- Try the jeans on before you cut anything
- Trim the excess and finish the raw edge
Step 3: Turn the jeans inside out and lay them flat

The inside of the denim needs to face outward for all the folding and pinning ahead. Flip each leg so the raw seams are showing. Smooth them flat on a hard surface like a table or countertop. Line up the inseam and outseam of each leg.
The front and back panels should sit evenly on top of each other. Your chalk mark from Step 2 should still be visible on the inside. If it rubbed off while handling, measure up from the bottom of the original hem by the same distance. Re-mark the line with a fabric pen.
Step 4: Fold the bottom of each leg up so the original hem sits at your mark

Your chalk mark is the target. With the jeans still inside out, grab the bottom edge of one leg. Fold it upward toward the knee. Keep folding until the crease of the original hem lines up with that chalk mark.
When the crease sits right on the mark, the fold is correct. The extra fabric will form a tuck hidden on the inside of the leg. Repeat on the other leg. Measure from the crotch seam to the hem crease on both sides. Those two numbers should match within 1/4 inch of each other.

Step 5: Pin the fold in place all the way around each leg

Flat straight pins slide under a sewing machine foot better than safety pins for this step. Start at the inseam and place one pin every 2 to 3 inches around the leg. Push each pin through all layers of the fold. When you reach the side seams, add an extra pin on each side of that thick junction.
Side seams stack four to six layers of denim. They shift if they are not locked down. Go around both legs, then flip the jeans right side out. Check that the original hem hangs evenly all the way around. If one side dips lower, unpin that section and re-fold.
Step 6: Thread your sewing machine with a denim needle and matching thread

A standard universal needle will bend or snap the moment it hits a side seam. Swap it for a 100/16 denim needle. Thread the top and the bobbin with all-purpose polyester thread that matches the color of the denim. Not the topstitch color.
The gold or orange thread on the original hem is decorative. Your new stitch line should disappear into the fabric, not stand out. Set the stitch length to 3 to 3.5mm. If your machine came with a zipper foot, attach it now. A zipper foot lets you sew closer to the folded edge of the original hem.
- Sewing machine with straight stitch
- Size 100/16 denim needle
- Zipper foot (optional but ideal)
- Iron and ironing board
- Fabric scissors
- Seam ripper (for mistakes)
- All-purpose polyester thread (match denim color)
- Straight pins
- Fabric chalk or washable marker
- Measuring tape or ruler
- Pinking shears (or use a zigzag stitch)
Step 7: Sew a straight stitch close to the fold around each leg

Remove the flat base from your sewing machine if it detaches. The narrow free arm underneath makes it far easier to slide a pant leg around the needle. Position the fold so your needle lands right next to the upper edge of the original hem.
The closer your stitch line is to that folded edge, the less visible the alteration will be on the outside. Backstitch 3 to 4 stitches at the start. Then sew all the way around the leg at a steady, slow pace. Backstitch again where you meet your starting point. Cut the thread tails and repeat on the second leg.
Step 8: Press the new seam flat with a hot iron and steam

This is not optional. An unpressed hem will flip outward every time you wash the jeans. Set your iron to the cotton or high heat setting. Flip the jeans inside out so the folded tuck is exposed. Press the seam allowance upward, away from the original hem.
Then flip the jeans right side out and press the original hem downward. Hold the iron in place for 8 to 10 seconds per section with steam. Work your way around the full leg. The heat resets the denim fibers so the fold lays flat on its own.

Step 9: Try the jeans on one more time before you cut anything

Put them on with the same shoes you used in Step 2. Walk around. Sit down. Stand back up. Look in the mirror from the front and the side. If one leg is shorter than the other, now is the time to catch it. You can still unpick the stitch with a seam ripper and re-fold. Once you pick up the scissors in the next step, there is no going back.
Step 10: Trim the excess fabric and finish the raw edge

Flip the jeans inside out one last time. The folded tuck of excess fabric is sitting above your new stitch line. Cut it away, leaving about 3/8 inch of fabric above the stitching. Do not cut closer than that or the seam could unravel after a few washes.
To stop fraying on the raw edge, you have three options: run a zigzag stitch along the cut edge using your sewing machine, trim with pinking shears to create a sawtooth edge, or apply a thin line of fray-stop liquid along the cut. Pinking shears are the fastest option for beginners. Flip the jeans right side out, give the hem one last press, and you are done.
