Hand hemming works best on straight hems and light to medium fabrics

You can hem pants without a sewing machine using a needle, thread, and one of three hand-sewing methods: a slip stitch (nearly invisible from the outside), a running stitch (faster but visible), or fabric glue (no needle required). The slip stitch takes longer but produces the cleanest result. A running stitch is quicker and holds well on casual pants. Fabric glue works on knits and stretchy fabrics but can feel stiff and may not survive heavy washing.

Hand hemming takes 30 minutes to an hour per pant leg, depending on the hem length and your speed. The method you choose depends on the fabric weight, how visible you want the stitches, and how much time you have. Lightweight fabrics like cotton blends and linen are easiest to hand hem. Heavy denim and thick wool take longer and require a stronger needle.

Key Takeaways

  • A slip stitch is the standard hand-hemming method because the thread runs inside the fold and is invisible from the outside.
  • You need a needle, thread that matches your pants, scissors, pins, and a measuring tape or ruler to mark the correct hem length.
  • Measure the hem length while wearing the shoes you plan to wear with the pants, standing on a flat surface.
  • A running stitch is faster than a slip stitch but leaves visible stitches on the inside of the hem.
  • Fabric glue is an option for stretchy fabrics and knits but creates a stiffer hem and may not hold through repeated washing.

Measure and mark the hem length before you cut

Put on the pants with the shoes you will wear them with and stand on a flat floor. Have someone measure from the floor to where you want the hem to end—usually about half an inch above the shoe. Mark that length on both pant legs with a fabric pencil or tailor's chalk, going all the way around each leg. The hem should be even on both sides.

If you are hemming alone, stand in front of a mirror and use a ruler or measuring tape to check that both legs are the same length from the floor. Uneven hems are the most visible mistake. Once you have marked both legs, try on the pants one more time to confirm the length feels right when you walk.

Fold and pin the hem to the correct width

Fold the pant leg up along your marked line and press the fold with your fingers or a warm iron. Most pants hems are 1 to 1.5 inches wide—check the original hem on the other pant leg or on a pair that fits you well. Pin the folded hem in place every 2 to 3 inches around the leg, keeping the pins parallel to the fold.

Try on the pants again with the hem pinned to make sure the length is correct and the fold sits flat. Walk around and bend your knees to check that the hem does not pull or bunch. If the hem looks right, you are ready to sew. If it is too long or too short, unpin it, adjust the fold, and repin.

Use a slip stitch for an invisible hem

Thread your needle and tie a knot at the end. Start on the inside of the hem fold, pushing the needle through the fold itself so the knot stays hidden. Bring the needle out about a quarter inch from where you started. Pick up one or two threads from the pant leg (not all the way through to the outside), then push the needle back into the fold directly across from where you came out. Slide the needle inside the fold for about a quarter inch and bring it back out. Repeat this pattern all the way around the pant leg.

The slip stitch works because the thread runs inside the fold and only catches a few threads from the pant leg itself, so it does not show on the outside. Keep your stitches small and even—about a quarter inch apart. When you reach the end, tie off the thread inside the fold and trim the excess. This method takes the longest but produces the most professional-looking result.

Use a running stitch if you need to work faster

A running stitch is simpler and quicker than a slip stitch. Start on the inside of the hem with a knotted thread. Push the needle through all layers of fabric (the fold and the pant leg), then back out about a quarter inch away. Keep going around the leg in a straight line, making small, even stitches. The thread will be visible on the inside of the hem, but not on the outside.

A running stitch is strong enough for everyday wear and holds up well in the wash. It works especially well on casual pants where the inside of the hem is not visible. Keep your stitches small and consistent—uneven stitches can cause the hem to pucker. When you finish, tie off the thread inside the hem and trim.

Fabric glue works on stretchy fabrics but has limits

If you do not want to sew at all, fabric glue (also called fabric adhesive) can hold a hem in place. explore a thin, even line of glue along the inside of the fold, then press the hem flat and hold it for 30 seconds. Let the glue dry completely according to the package instructions—usually 24 hours—before wearing the pants.

Fabric glue works best on knits, stretchy fabrics, and lightweight materials that are hard to hand sew. It does not work well on heavy fabrics like denim. The glued hem will feel slightly stiff and may crack if you bend the pant leg sharply. Glued hems can also separate after several washes, especially in hot water. If you use fabric glue, wash the pants in cold water and hang them to dry rather than using a dryer.

Reinforce the hem at stress points if it will get heavy wear

If you hemmed pants that you wear often or that get a lot of movement—work pants, athletic wear, or children's clothes—add extra stitches at the side seams where the hem meets the pant leg. These stress points take the most strain when you walk and bend. Use a slip stitch or running stitch to go back and forth over the side seams two or three times, creating a small reinforced area.

You can also add a second row of stitches about a quarter inch above the first row if you want extra durability. This is especially useful on pants made from lightweight fabric or on hems that will be washed frequently. Reinforced hems last longer and are less likely to come loose after a few months of wear.

Frequently Asked Questions

What kind of thread should I use?

Use all-purpose polyester or cotton thread that matches the color of your pants as closely as possible. If you cannot find an exact match, choose a shade slightly darker than the fabric—it will be less visible than a lighter shade. Use regular sewing thread, not embroidery thread or yarn, because sewing thread is strong enough to hold the hem through washing and wearing.

Can I hand hem stretchy fabrics like leggings or athletic wear?

Hand hemming stretchy fabrics is difficult because the stitches can break when the fabric stretches. Fabric glue is a better choice for leggings and athletic wear. If you want to hand sew, use a stretch stitch or a running stitch with elastic thread, but expect the hem to be less durable than on non-stretch fabrics.

How do I fix a hand-sewn hem that came loose?

If a few stitches came out, you can restitch that section using the same method you used the first time. If the entire hem separated, you may need to remove all the old stitches, re-fold the hem, and sew it again from scratch. Use a seam ripper or small scissors to carefully cut and remove the old thread.

Will a hand-sewn hem last as long as a machine-sewn hem?

A well-sewn hand hem will last through regular washing and wearing, but a machine-sewn hem is more durable because the stitches are tighter and more consistent. Hand-sewn hems work well for pants you wear occasionally or for quick fixes. For pants you wear every day, a sewing machine produces a longer-lasting result.

What if the hem puckers or looks uneven after I sew it?

Puckering usually happens when stitches are too tight or too close together. Remove the stitches and resew with slightly looser tension and stitches spaced a bit farther apart. Press the hem with a warm iron after you finish sewing to help it lie flat. If the hem is uneven, you may have folded it at different widths around the leg—measure and repin before resewing.
