How to Repair a Ripped Hem on Jeans

The short answer: stitch first, patch when you must

A ripped or frayed hem on jeans does not mean the pair is finished. If the tear is only in the stitching along the fold, you can usually refold the hem and sew it back down with a straight stitch. If the fabric itself is torn or missing, put a patch behind the damaged area or replace the hem with a fresh fold.

Start by laying the jeans on a flat surface and looking at both the outside and the inside of the hem. You are checking two things: how much fabric is left in the hem allowance, and whether the denim around the tear still feels strong. The hemming and cuffing guide explains how to measure and fold a hem, while the jeans hem types guide can help you identify what kind of hem you are working with.

Why hems fray and why repair is worth it

A hem rubs against shoes, floors, bicycle pedals, and the inside of a washing machine every time you wear or wash the jeans. Over time the threads along the fold wear out faster than the denim in the seat or thigh. That is why a pair of jeans with plenty of life left can still develop a frayed or torn hem.

Repairing the hem keeps the garment in use. EPA estimated that in 2018, 17 million tons of textiles were generated in the United States and 11.3 million tons were landfilled. A simple hem repair can delay that outcome for a pair you already like. According to CottonWorks, cotton can be a circular textile, and cotton microfibers can biodegrade after use, so the cotton in a repaired pair has a better end-of-life prospect than a pair thrown away early.

Denim is a cotton fabric, and cotton is an agricultural fiber. The USDA Agricultural Research Service is part of the U.S. Department of Agriculture, with research that supports agricultural producers. Knowing that your jeans start as a natural fiber can make a small repair feel like a reasonable investment in the garment.

Stitching options for a frayed hem

For a hem that is frayed but still has its fabric, trimming loose threads and resewing is usually the cleanest repair. Press the hem flat first so the original fold line is visible. Pin the fold in place, then run a straight stitch along the existing topstitching line. If the raw edge is shedding, use a zigzag stitch or an overcast stitch before folding so the threads do not continue to unravel.

You do not need a sewing machine. A small running stitch or whip stitch by hand can hold a hem if you keep the stitches even. Use a thread that matches the denim topstitching if you want the repair to disappear, or a contrasting thread if you want the repair to read as a design detail. For more on stitch types, see the seam repair guide.

• Straight stitch along the original hem line when the fold is intact.
• Zigzag the raw edge before folding when the hem is shedding threads.
• Topstitch from the outside with a matching or contrasting thread.
• Hand sew a whip stitch or running stitch for a no-machine repair.

Patching a torn hem

When the tear goes through the hem or reaches above it, stitching the two sides together may not hold because there is no fabric to anchor the stitches. A patch is a stronger fix. Cut a piece of denim slightly larger than the tear, place it behind the damaged area, and pin it in place. Stitch around the patch with a straight stitch, then zigzag over the edges to keep them from fraying.

For a cleaner look, use a patch that is close to the fabric weight of the jeans. A stiff patch on a lightweight pair will feel bulky; a thin patch on heavyweight denim may tear again. An inside patch keeps the repair subtle, while an outside patch is a visible fix that some people choose as a style detail. If you are unsure about the fabric structure, the denim fabric construction guide and the jeans patching guide cover the basics.

Replacing the hem instead

If the damaged edge is too short to refold, replacing the hem is the better option. Remove the old stitching, press the fabric flat, and trim the damaged edge. Fold the fabric up to your target length and sew a new hem. The result will be slightly shorter than the original, or the same length if the original hem allowance gave you enough fabric to work with.

You can also turn the exposed hem into a roll or cuff, which avoids sewing over a worn fold. New stitching will be easier to maintain than stitching through damaged fabric. For length choices, use the inseam length guide and the break length guide before you cut.

When repair is not worth it

A repair is only as strong as the fabric around it. If the denim near the hem feels thin, has holes spreading upward, or has lost its shape, stitching and patching may not last. In that case, replacing the jeans is the more practical route. If the hem is fraying because the leg is too long and drags on the ground, shorten or cuff the leg, or the same damage will return.

If you decide to replace the pair, choose a style that fits how you actually use the jeans. A classic straight leg jean gives you a clean hem that is easy to re-hem later, while work jeans tend to be built from sturdier fabric that resists fraying along the cuff.

What to pick for your use

Questions

Do I need a sewing machine to repair a ripped hem?

No. A hand-sewn running stitch or whip stitch can hold a hem if you work carefully. A machine stitch is faster and stronger for denim, especially if the hem is exposed to heavy wear.

Should I trim frayed threads before sewing?

Yes, trim only the loose threads that are pulling away from the fabric. Do not cut into the denim itself, because the hem needs that fabric for the stitch to anchor into.

Can I use fabric glue instead of stitching?

Fabric glue can act as a temporary fix, but stitching is more durable for a denim hem that gets washed and rubbed. Glue alone may crack or peel after a few washes.

How do I prevent the same hem from fraying again?

Keep the leg from dragging on the ground, use a zigzag or overcast stitch on the raw edge before folding, and wash the jeans inside out on a gentle cycle. Air drying reduces wear on the repaired edge.

What if the tear is too large for a simple stitch?

Patch the area behind the tear or replace the hem. If the surrounding fabric is thin or tearing further, the pair may be better replaced.
