What a cuff is and why you sew it instead of hemming
A cuff is a folded band of fabric sewn to the edge of a sleeve or pant leg. Unlike a straightforward hem, which folds the raw edge inward once and stitches it down, a cuff is a separate piece of fabric (or a fold of the existing fabric) that wraps around the opening and gets sewn on both sides. The result is a finished, structured edge that looks intentional and holds its shape through washing and wearing.
You choose a cuff over a hem when you want a more polished look, when you need to shorten a garment without losing fabric weight at the edge, or when the original design calls for one. Cuffs are standard on dress shirts, many pants, and tailored jackets. They're also easier to adjust later than a hem—you can let out a cuff or take it in by a small amount without ripping out stitches.
Key Takeaways
- A cuff requires two seams: one to attach the cuff to the garment opening, and one to fold and close the cuff itself.
- Measure the opening of the sleeve or pant leg, then cut your cuff strip to that length plus half an inch for seam allowance on each end.
- Sew the cuff to the garment with the right sides facing each other, using a quarter-inch seam allowance, then fold and stitch the cuff closed on the inside.
- Press the cuff flat after each seam to keep edges sharp and prevent puckering when you wear the garment.
- A cuff typically measures one to two inches wide when finished, depending on the garment style and your preference.
Measuring and cutting your cuff strip
Start by measuring the opening where the cuff will go. Wrap a soft measuring tape around the sleeve opening or pant leg opening, keeping it snug but not tight—the way the garment will sit on your body. Write down this measurement. If you're making a cuff from a separate piece of fabric, add one inch to this measurement (half inch on each end for seam allowance).
Decide how wide you want the finished cuff to be. Most dress shirt cuffs are one and a half inches wide; casual shirt cuffs are often one inch; pant cuffs are typically one and a half to two inches. To cut your strip, double this width and add half an inch for seam allowance. So a one-and-a-half-inch finished cuff means you cut a strip three and a half inches wide.
Cut your strip along the grain of the fabric, running parallel to the selvage (the finished edge). This keeps the cuff from stretching out of shape. If you're using a knit fabric, cut slightly narrower and use a stretch stitch or ballpoint needle to prevent runs.
Preparing the garment opening
Before you attach the cuff, finish the raw edge of the sleeve or pant leg opening. The easiest method is a zigzag stitch: set your machine to a medium zigzag (width 2.5 to 3, length 2.5), and stitch along the raw edge. This prevents fraying and gives the seam a professional appearance. If your fabric is prone to fraying heavily, use a serger or a three-step zigzag instead.
Press the garment opening flat with an iron. If the opening is curved (as most sleeve openings are), you may need to ease it slightly—use a longer stitch length and gentle tension to gather the fabric very slightly so it lies flat. This is optional for straight pant legs but important for sleeves.
Attaching the cuff to the garment
Fold your cuff strip in half lengthwise, with the wrong sides facing each other, and press it with an iron. This creates a center fold that will become the outer edge of the finished cuff. Open it back up—you now have a crease down the middle.
Pin the cuff to the garment opening with right sides facing each other (the pretty sides facing inward). Align the raw edges of the cuff with the raw edge of the sleeve or pant leg. The cuff should wrap all the way around; overlap the ends by half an inch and pin them together. Stitch around the entire opening using a quarter-inch seam allowance. Backstitch at the beginning and end to lock the seam.
Press the seam flat with an iron, pressing the seam allowance toward the cuff. This makes the next step easier and prevents the seam from puckering.
Folding and closing the cuff
Fold the cuff up along the crease you pressed earlier, so the right side of the cuff now faces outward. The raw edge of the cuff should now be hidden inside. Press the fold with an iron to set it.
Fold the raw edge of the cuff inward by half an inch and press again. You now have a finished edge ready to stitch. Pin this folded edge to the inside of the garment, covering the seam you just made. The stitching line should sit just below the original seam so it's hidden when the cuff is worn.
Stitch the cuff closed using a straight stitch, sewing as close to the fold as you can without catching the outer layer of the cuff. Backstitch at the start and end. Press the finished cuff flat.
Common mistakes and how to avoid them
The most common error is cutting the cuff strip too short. Always add at least one inch to your opening measurement before cutting—you need that overlap to join the ends neatly. If your cuff ends don't meet, you'll have a gap that looks unfinished.
Another frequent problem is not pressing between steps. Pressing after the first seam and again after folding keeps the cuff from twisting or puckering. Skipping the press step often results in a cuff that looks wavy or doesn't lie flat against your arm or leg.
Uneven seam allowance is also common, especially on curved openings like sleeves. Use a quarter-inch presser foot if your machine has one, and go slowly around curves. If the seam allowance varies, the cuff will bunch on one side and pull on the other.
Finishing touches and care
Once the cuff is complete, try on the garment and check that the cuff sits evenly and doesn't twist. If one side is higher than the other, you may have eased the opening unevenly. You can unpick the seam and re-stitch if needed, but most minor unevenness will settle after the first wash.
When you wash the garment, turn it inside out to protect the cuff seams. Dry on low heat or air-dry to prevent shrinkage. Press the cuff with an iron on low to medium heat, depending on your fabric. A well-sewn cuff will hold its shape for years of wear.
Frequently Asked Questions
Can I add a cuff to a garment that already has a hem?
Yes, but you'll need to remove the existing hem first. Carefully unpick the hem stitches, press the fabric flat, and then follow the steps above. If the garment is too short after removing the hem, you may not have enough fabric to add a cuff.
What if my cuff ends don't line up evenly when I overlap them?
Trim the overlap so both ends are even, then stitch them together with a small seam before attaching the cuff to the garment. This creates a smooth, invisible seam when the cuff is folded.
Do I need a special presser foot to sew a cuff?
A quarter-inch presser foot makes it easier to keep your seam allowance consistent, but it's not required. A standard presser foot works fine if you sew slowly and use the edge of the foot as a guide.
Can I sew a cuff on a knit fabric like jersey or fleece?
Yes, but use a ballpoint needle and a stretch stitch (or a narrow zigzag) instead of a straight stitch. This allows the seam to stretch with the fabric and prevents it from breaking when you pull the garment on.
How do I fix a cuff that's twisted after sewing?
If the twist is minor, press it firmly with an iron and it will usually stay in place. If it's severe, you may need to unpick the inner seam, straighten the cuff, and re-stitch it. This is why pressing between steps is important—it prevents twisting before it becomes a problem.
