Learn Simple Techniques for Professional-Looking Hems That Save Money and Extend the Life of Your Wardrobe
Dear Readers and Subscribers,
A well-fitting pair of pants or jeans can make all the difference in comfort and appearance. Unfortunately, ready-to-wear clothing is rarely made for every height, and many people find themselves purchasing pants that are several inches too long. Instead of paying for professional alterations every time you shop, learning to hem pants and jeans yourself is an easy sewing skill that will save you money and help your clothes fit perfectly.
Whether you're shortening dress pants for work, hemming casual cotton pants, or preserving the original hem on your favorite jeans, the process is easier than you might think. With a few basic sewing tools and a little patience, you'll be able to create clean, professional-looking hems that last through years of wear.
Why Hem Your Own Clothing?
Hemming your own garments offers several advantages:
Save money on alteration costs.
Customize every pair of pants to your exact height.
Improve the overall appearance of your wardrobe.
Extend the life of your favorite clothing.
Gain confidence in your sewing skills.
Once you learn the basics, you'll be able to hem everything from jeans and trousers to capris, shorts, skirts, and even sleeves.
Supplies You'll Need
Gather your supplies before you begin:
Sewing machine
Matching thread
Sharp fabric scissors
Pins or sewing clips
Seam gauge or ruler
Fabric marking pencil or chalk
Iron and ironing board
Measuring tape
For jeans, you may also want:
Denim sewing needles (size 90/14 or 100/16)
Heavy-duty polyester thread
Hump jumper or folded fabric scrap to help sew over thick seams
Instructions
Step 1: Try On the Pants
Put on the shoes you plan to wear with the pants. Different shoes change the ideal pant length.
Stand naturally while someone marks the desired finished length. If you're working alone, fold the excess fabric under and pin it in place while standing in front of a full-length mirror.
Remember:
Dress pants usually skim the top of your shoes.
Casual pants may sit slightly above the heel.
Jeans often look best with a slight break over the top of your shoes.
Step 2: Measure Carefully
Lay the pants flat.
Measure from the bottom of the existing hem to your marked finished length.
Check both pant legs carefully. It's surprisingly common for one leg to measure slightly differently than the other, so always verify your measurements before cutting.
Step 3: Add Hem Allowance
Don't cut at the finished length.
Most pants require a hem allowance of 1 to 2 inches.
For example:
If you need to shorten the pants by 3 inches and want a 1½-inch hem, measure and mark accordingly before trimming away excess fabric.
Always double-check your measurements before making the first cut.
Step 4: Cut the Excess Fabric
Using sharp fabric scissors, carefully trim away the extra fabric.
Cut both legs evenly.
Take your time—it's much easier to trim a little more later than to replace fabric that has already been removed.
Step 5: Finish the Raw Edge
Depending on your fabric, you may want to finish the raw edge before hemming.
Options include:
Zigzag stitch
Overlock stitch
Serger
Pinking shears for fabrics that fray very little
This helps prevent fraying after repeated washing.
Step 6: Press the Hem
Fold the hem allowance to the inside.
Use your iron to create a crisp fold.
Accurate pressing is one of the secrets to a professional-looking hem.
Pin or clip the folded edge securely in place.
Step 7: Stitch the Hem
Using matching thread, sew close to the folded edge.
Take your time and sew slowly to keep the stitching even.
Remove pins as you sew.
Backstitch at the beginning and end to secure your stitches.
Press the finished hem one final time for a polished appearance.
Hemming Jeans
Jeans require a few additional considerations because denim is thicker than most fabrics.
Use the Right Needle
Install a denim needle to help sew through multiple layers without skipped stitches.
Choose Strong Thread
Heavy-duty polyester thread provides strength while maintaining a neat appearance.
Slow Down Over Thick Seams
The side seams can become bulky.
If your machine struggles, use a hump jumper or place a folded scrap of denim behind the presser foot to keep it level as you sew across the thick seam.
Match the Original Stitching
Many jeans feature golden topstitching.
If you want the alteration to blend in, choose thread that closely matches the original color.
Preserve the Original Jean Hem
If you love the factory finish on your jeans, you don't have to remove it.
Instead, shorten the jeans above the original hem and reattach the factory hem. This technique keeps the authentic faded edge while achieving the perfect length.
It's especially useful for designer jeans or jeans with decorative stitching.
Common Mistakes to Avoid
Even experienced sewists occasionally make mistakes. Avoid these common problems:
Measuring without wearing shoes.
Forgetting the hem allowance.
Cutting before double-checking measurements.
Skipping pressing between steps.
Using dull scissors.
Sewing too quickly.
Forgetting to check that both pant legs are the same length.
Taking a little extra time produces much better results.
Caring for Your Newly Hemmed Garments
Wash and dry your garments according to the fabric care instructions.
Inspect the hem occasionally for loose stitches, especially on frequently worn jeans.
A quick repair at the first sign of wear can keep your hem looking neat for years.
Learning how to hem pants and jeans is one of the most useful sewing skills you can develop. Whether you're shortening new purchases or giving older garments a better fit, a neatly sewn hem can completely change the way clothing looks and feels.
With a few simple tools, careful measuring, and plenty of pressing, you'll be able to create professional-looking results right from your own sewing room.
