Quick answer
Jeans come in a few set inseam lengths, so many people need to shorten them. The free fix is a neat cuff. For a flat hem that looks finished, fold the extra length inside and fuse it with iron-on hem tape. Owners report that tape made for denim holds through normal washing when it is pressed well, and it needs no sewing.
Free fix vs. permanent fix
Roll a cuff
- Roll the hem up one or two turns, the same on both legs
- Press the fold flat with your hand or a warm iron
- Add a few safety pins inside the fold if it keeps unrolling
- Works best on casual, straight or relaxed fits
How long it lasts: As long as you like the cuffed look. The roll can unfold, and it adds bulk at the ankle.
Heavy-duty iron-on hem tape
A cuff changes how the jeans look. Hem tape does not. You fold the extra length inside and melt a bonding strip between the layers, which gives a clean, finished edge with no stitching. Tape sold for denim is made to bond thick fabric.
What to get: Heavy-duty iron-on hem tape for denim
How long it lasts: Many washes, when it is pressed well and left to cool. The hem stays flat, with no bulky roll.

Why it happens
Standard inseam sizes
Most jeans are cut in a few inseam lengths, often in steps of about 2 inches. If you are between sizes or on the shorter side, the nearest length is still too long.
Your shoes change the right length
A hem set for boots or heels drags under flat shoes. Choose the shoes you wear most and measure for those.
Jeans worn below the waistline they were cut for
Jeans that sit lower on your hips than designed hang lower on the leg, so the hem ends up longer than the size suggests.

Do these in order, starting with the simplest.
-
Mark the length in the shoes you wear most
Tool used: Chalk or a pencilPut the jeans on with those shoes and stand straight. For most straight and slim fits, the hem should just touch the top of the shoe at the front and sit about half an inch off the floor at the back. Pin or chalk the spot on each leg.
-
Measure the extra and trim if it is large
Tool used: Tape measure or rulerTake the jeans off and measure from the original hem up to your mark on each leg. If the extra is under 2 inches, you can fold it as it is. If it is more, cut off the excess straight across, leaving 1 inch below your mark to fold under.
-
Fold the extra inside and press the crease
Tool used: Iron and ironing boardTurn the jeans inside out. Fold the hem up so the fold sits at your mark, then press the crease flat with the iron. Lay a thin cloth over dark denim so it does not shine.
-
Fuse the tape between the layers
Tool used: Heavy-duty iron-on hem tapeSlide a strip of tape between the fold and the leg, just inside the crease edge, and overlap the ends by half an inch. Cover with the cloth and press hot for 10 to 15 seconds per spot, or as the pack says. Lift the iron instead of sliding it. Give thick seam crossings a few extra seconds.

Let it cool, then press the other side
Leave the hem flat until it cools, since the bond sets as it cools. Turn it over and press the outside through the cloth. Give the tape the full set time on the pack, often up to a day, before the first wash. Then wash cold and tumble low.
When free fixes aren't enough
A cuff is fine when you like the look and the extra is 2 inches or less. It stops working on dress jeans, on slim legs that look lumpy cuffed and on long extras that make a thick roll at the ankle. Hem tape is the step up, since the hem stays flat and looks finished. The weak spot is thick seams, so give them extra press time. If the tape lifts after a few washes, press it again or add a thin line of fabric glue. For expensive or very heavy raw denim, a tailor is the safer choice.

How we picked: How we picked: this page is based on the instructions hem-tape makers print on the pack, garment care guides, and the problems and fixes people report in owner reviews. We do not test products by hand.
How long should the hem be?
- Straight or slim fit: the hem just touches the top of the shoe at the front, with about half an inch of space at the back.
- Bootcut or flare: longer, so the hem nearly reaches the floor in the shoes you wear most, usually boots or heels.
- Skinny or cropped: at or just above the ankle bone. Do not hem these to the floor.
- Relaxed or wide leg: a small break at the shoe is fine, but keep the back hem off the floor so it does not fray.
What to skip
Staples, double-sided clothing tape and safety pins
Staples rust and can snag skin. Double-sided fashion tape is meant for short-term jobs and lets go in the wash. Safety pins slip loose. For a hem you plan to wear and wash for months, use hem tape or glue made for fabric.
