How to Hem Pants by Hand

You don't need electricity or expertise to shorten pants—just patience and the right stitch. Here's how to execute a clean, durable hem that holds.

Fig. 01 · Hand-hemming requires only a needle, thread, and precision measurement.

A hand-sewn hem is quieter than a machine, more forgiving than you'd think, and requires nothing but a needle, thread, scissors, and a measuring tape. Whether your pants are slightly too long or you're avoiding the dry cleaner, this technique works on denim, cotton, wool, and most woven fabrics.

The key is using the right stitch—the blind stitch, also called a ladder stitch—which hides your thread inside the fold of fabric. Done correctly, it's nearly invisible from the outside and surprisingly durable for everyday wear.

The blind stitch is your secret weapon: it runs inside the fold, so your stitches never show on the outside of the pant leg.

What you'll need.

  • 01Needle (size 7–9 for most fabrics)
  • 02Thread (color-matched to fabric)
  • 03Measuring tape
  • 04Tailor's chalk or fabric pen
  • 05Sharp fabric scissors
  • 06Iron (optional but recommended)
  • 07Thimble (optional, protects your finger)

Step one · 1 minute

Measure and mark your desired length

Put on the pants with the shoes you'll wear them with. Have someone measure from the floor to where you want the hem to hit—typically at the top of your shoe or just grazing it. Mark this line with tailor's chalk or a fabric pen all the way around the leg. Remove the pants and measure how much fabric needs to be removed. Add 1 inch to that measurement; this is your fold depth.

Always measure while wearing the shoes you'll pair with these pants. A half-inch difference changes everything.

Cut the excess fabric

Lay the pants flat on a table with the leg extended. Cut along your chalk line with sharp fabric scissors, cutting straight across. Leave about 0.5 inches below your line as a safety margin—you can always trim more, but you can't add fabric back. Cut both legs to the same length by measuring twice.

Use scissors designated for fabric only; dull or multipurpose scissors will fray the edge and make hemming harder.

Fold and press the hem

Fold the raw edge up 0.25 inches and press it with your fingers or a hot iron set to low heat (check your fabric first). Then fold the entire hem up by your desired depth—typically 1 to 1.5 inches—and press again. This double fold hides the raw edge inside and gives you a clean line to work with.

If you have an iron, use it. The crease holds the fabric in place and makes stitching exponentially easier.

Thread your needle and knot the end

Cut about 18 inches of thread and thread your needle. Tie a small knot at the end. Choose thread that matches your fabric color as closely as possible; if you can't find an exact match, go one shade darker rather than lighter. Start with one pant leg and work around the entire circumference before moving to the second leg.

A knot that's too large will be visible from the outside. Make it the size of a small pea.

Step five · 4 minutes

Execute the blind stitch

Start at an inside seam where your stitches will be hidden. Push the needle through the fold of the hem (not through both layers) and slide it about 0.25 inches along the fold. Exit the fold and push the needle directly across into the pant leg fabric, catching only a few threads of the outer layer. Slide the needle 0.25 inches inside the pant leg, then re-enter the fold. Repeat this pattern all the way around. Keep your stitches small and consistent—about 0.25 inches apart. Your thread should never be visible on the outside of the pant leg.

Go slowly. This stitch is forgiving; uneven spacing is far less noticeable than a stitch that pokes through to the outside.

Step six · 1 minute

Secure and finish

When you reach the end, make a small stitch in place three times to lock the thread. Trim the excess thread and try on the pants. Walk around and bend your knees to test the hem. If it feels secure and looks even, you're done. If you notice any loose spots, add a few reinforcing stitches.

A small stitch in place means pushing the needle through the same spot multiple times without advancing along the hem.

How to know your hem is done right

A successful hand-sewn hem sits evenly around the entire pant leg, feels secure when you tug on it, and shows no visible stitches from the outside. The hem should move with the fabric naturally and not create a stiff band.

Questions at the mirror.

My thread keeps breaking. What am I doing wrong?

You're likely pulling too hard or using old, brittle thread. Use fresh thread, keep tension gentle and even, and don't yank the needle through. If you're working with delicate fabric, use a thinner needle and lighter thread.

I can see my stitches on the outside of the pant leg. How do I fix this?

You're catching too many threads in the outer fabric layer. Unpick that section and try again, catching only 2–3 threads of the pant leg itself. The stitch should be almost imperceptible from the outside.

How long will a hand-sewn hem last?

A properly executed blind stitch lasts through regular wear and many washes. If your hem starts to come loose after months of wear, you can reinforce it with a few additional stitches rather than redoing the entire hem.

Can I use this method on stretch fabrics like jeggings?

Yes, but use elastic or stretch thread for better recovery. Regular thread can snap on stretch fabrics. The blind stitch still works—just be gentler with tension.
