How to iron pants with a crease

Check the label and set the iron

The dots on the iron symbol tell you the ceiling. Under the GINETEX care labeling system, one dot means a soleplate of at most about 248°F (120°C) and no steam, typical for acrylic and nylon. Two dots allow about 320°F (160°C), the setting for wool, silk, polyester and viscose. Three dots allow about 410°F (210°C) for cotton and linen. GINETEX is clear that you set the heat by the label, not by guessing the fiber, because blends and finishes change the answer. If a symbol is unfamiliar, our guide to reading care labels explains each one.

Before you start, test the heat on a hidden spot such as the pocket bag or the inside of the waistband. Have a press cloth ready: a clean, plain cotton handkerchief or a piece of old white sheet works. Dampen it for wool and for dark fabrics, which turn shiny when a hot soleplate flattens their surface. Wash the pants first if they are dirty, since heat can fix a stain in place. If you do scorch something, our guide on removing scorch marks covers what can and cannot be rescued.

How to iron pants with a crease, step by step

This order comes from home sewing practice, and it works because you finish the bulky top before you touch the legs, so nothing you have already pressed gets crushed again. Use a padded ironing board and give yourself room at the narrow end.

1. 01

   Press the pockets from the inside

   Turn the pants inside out, pull the pocket bags out flat and press them. Flat pockets will not leave lumpy outlines on the front when you press over them later. Turn the pants right side out again.

2. 02

   Work the waistband around the board

   Slide the waist over the narrow end of the board and press the waistband and the upper section down to the crotch, rotating as you go. Use light pressure here. Pressing hard over zippers, pocket bags and seams can leave a shiny imprint of them on the outside, and on some fabrics that mark is permanent. If there are pleats, set them where they were stitched and steam them lightly into place.

3. 03

   Line up the seams and find the crease

   Lay the pants along the board, legs together, and fold each leg so the inseam sits exactly on top of the outseam. When the seams match, the old crease appears on its own at the front and back edges. Flip the upper leg back out of the way so you are working on one leg at a time.

4. 04

   Press the crease under a damp cloth

   Lay the press cloth over the fold and press: set the iron down for a few seconds, lift it, move a few inches along, and set it down again. Keep the weight of the iron on the fold itself, not on the side seams, so they do not print through.

   CheckYou should see a clean, flat edge with no second line beside it.

5. 05

   Let it cool, then do the other leg

   Leave the leg on the board until it is cool to the touch before you move it. This is what sets the line. Then swap legs and repeat. On heavy wool, some tailors hold a wooden clapper on the crease while it cools to make the line sharper.

6. 06

   Hang the pants straight away

   Hang them by the cuffs from a clip hanger or fold them over a bar along the crease. Leaving them over a chair undoes half the work.

Where the crease should go

Always follow the crease the maker pressed. A trouser crease runs down the center of each leg, front and back, and on pleated pants the front crease usually rises to meet the inner pleat at the waist. The back crease often stops around the seat. A sewing guide from the Home Sewing Association notes that some people press flat front pants firmly only in the lower leg, so the legs hang straight without a hard line all the way up. Both are accepted; what matters is consistency.

A second crease, the classic ironing mistake, happens when the seams were not lined up and the new fold lands beside the old one. Fix it quickly: dampen the wrong line with a spray bottle or a wet press cloth, press it flat with steam, let it dry, then fold again with the seams matched. Wool usually forgives this. Some cotton and polyester fabrics keep a faint ghost of the old line, so it pays to check the seams before the first press.

Jeans, chinos, wool and polyester pants

Wool trousers take the classic press best. Use the two dot setting, plenty of steam, a damp cloth every time, and never slide the iron. Wool is also naturally crease resistant, so a trouser that is only slightly rumpled may just need a hanger and a steamy bathroom. Cotton chinos can be ironed hotter and are easiest while still slightly damp from the wash. Whether you crease chinos is a matter of taste: a crease reads dressier, a flat leg more casual.

When people ask how to iron jeans, the usual answer is inside out, on the cotton setting, with the fabric slightly damp. Pressing from the inside protects the color and avoids shine on the outer face. Most people do not put a crease in jeans at all. Our guide on washing jeans explains why many denim wearers skip ironing entirely.

Can polyester pants be ironed? Yes, carefully, at low to moderate heat and under a press cloth, because polyester can melt or turn glossy at cotton temperatures. In return, polyester holds a heat set crease well once it cools. For linen, go hot and damp and accept that linen will soften again after an hour of wear. If you would rather not have a crease at all, iron each leg flat with the seams side by side rather than stacked, or slip a rolled towel inside the leg so no fold forms.

Can you iron pants with a steamer?

A steamer is excellent at one job for pants: relaxing wrinkles. Hang the pants from clips at the hem so the legs fall straight, pull the fabric gently taut with one hand and move the nozzle slowly down each leg. Sitting creases behind the knee and folds from a drawer will soften and drop out. What a steamer cannot do is create a sharp front line, because a crease needs pressure as well as heat and moisture.

A practical routine is to steam between wears and press only when the crease has gone. Woolmark also suggests hanging wool pants in a steamy bathroom to refresh them, which is gentler still. Our guides to using a garment steamer and getting wrinkles out without an iron cover the details for travel and busy mornings.

Keep the crease between wears

Pressed pants stay sharp much longer if they rest properly. Hang them the same day, either upside down by the cuffs, which lets their own weight pull out light wrinkles, or folded over a trouser bar with the creases lined up. Give wool a day off between wears so it can recover, and brush it before hanging to lift dust from the weave. Our guide on hanging clothes compares hanger types.

If you would rather never press the line again, sewists have two permanent options: stitching very close to the fold, which shows as a fine seam, or fusing the crease from inside with fusible thread. Both change the garment for good, so they suit work pants you wear constantly more than good suit trousers. And if the pants still look wrong after pressing, the issue may be length or fit rather than wrinkles; see how long dress pants should be.
