How to Hem Jeans Perfectly — With or Without a Sewing Machine

Why Hemming Your Own Jeans Makes Sense

As someone who has altered thousands of jeans professionally, hemming is a valuable skill that customizes your garments for a perfect fit. Whether altering jeans bought off the rack or resizing old favorites, achieving a tailor-made fit is empowering.

Key Takeaways

  • Preserving the original hem for an authentic look.
  • Creating a new hem when necessary or desired.
  • Hemming by hand if a sewing machine isn’t available.

Tools You’ll Need for Hemming Jeans

Having the right tools ensures precision and ease. Here’s a list of essential and optional tools I’ve trusted in my career:

  • Sewing Machine: A must-have for machine hemming.
  • Fabric Scissors: Essential for clean cuts; I recommend Fiskars.
  • Measuring Tape: Precision tool for measuring the perfect length.
  • Pins and Chalk/Fabric Marker: For marking lengths and keeping fabric in position.
  • Iron: Recommended to press seams for a professional look.

How to Hem Jeans With Original Hem

Preserving the factory finish is my most-requested technique. Here’s how to master it:

  1. Measure and mark the desired length with chalk.
  2. Fold the original hem up to the chalk line and pin in place.
  3. Sew as close to the original hem as possible using a sewing machine.
  4. Press the seam with an iron to finish.

Measuring Correctly for the Perfect Length

Proper measurement ensures a tailored look. Use a measuring tape and mark the desired hem allowance. Different styles like skinny or bootcut may require unique approaches.

  1. Wear the shoes you’ll pair with the jeans.
  2. Measure from the crotch to the desired length.
  3. Add an allowance for shrinkage if washed.

Machine Sewing the Original Hem

For professional results, specific settings are crucial. Use a topstitching needle and straight stitch. Handle thick seams carefully to avoid needle breakage. A walking foot can also be beneficial.

  • Tip: Adjust stitch length appropriately.

How to Hem Jeans By Creating a New Hem

When a new hem is necessary, forgoing the original hem is the way to go. Here’s how:

  1. Mark the cut line using chalk.
  2. Cut the fabric with scissors.
  3. Fold and pin for a clean finish.
  4. Sew the seam using a sewing machine.

Matching Thread Color and Stitch Style

Choosing the right thread and stitch style makes all the difference. Use polyester threads for durability. My professional trick includes testing different colors on a scrap piece of denim.

  • Brands: Gutermann or Coats & Clark

How to Hem Jeans By Hand (No Sewing Machine Needed)

For those without a machine, or if in an emergency, hand hemming is a reliable technique:

  1. Mark the desired length with chalk.
  2. Fold and pin the fabric.
  3. Use a backstitch for durability.

Hemming Different Jean Styles

Each jean style poses its challenges, but I adapt with ease. Skinny jeans require a narrow hem, while wide leg or bootcut may benefit from overlock finishing.

Proper hemming requires accurate measuring and the right tools. You can either preserve the original hem for an authentic look or create a new hem, depending on the jeans style and your preference.
To keep the original hem, fold the existing hem upward inside the pant leg, then stitch around the fold. This preserves the original factory finish while adjusting the length.

Conclusion

Hemming your jeans can elevate their fit from ordinary to bespoke. With these techniques, you’ll create perfectly tailored pieces, making your jeans shopping experience uniquely satisfying.

If you’re working with heavily soiled denim, consider prewashing before hemming to prevent shrinkage after the repair. Learn why this step is essential: Turn Prewash Into the Essential Laundry Step You Never Skip.

For a durable hem, proper thread tension is crucial. A loose stitch will unravel in the wash. Check your machine settings with our detailed guide: Thread Tension Guide.
