How to Iron a Shirt: Collar to Back, Step by Step

Ironing has exactly two ways to go wrong, and both are avoidable. You re-wrinkle a panel you already smoothed, or you scorch the cloth with the wrong heat. The first is solved by order, the second by reading one symbol on the care label. Get those two right and the rest is just technique.

The order works because you start with the small, fixed zones — the collar and cuffs — and finish with the large panels. Eton and Downy, a shirtmaker and a laundry brand, both start at the collar and leave the front until after the collar and cuffs (they differ on where the sleeves and the yoke fall). Iron the big front panel first and you risk crushing it again reaching across it to do the collar; do the collar first and later passes are less likely to disturb it. That is the whole rule: fixed, fiddly bits first; big flat expanses last.

Before you start

What you’ll need

Four things cover almost every shirt. An iron↗ with a temperature dial that matches the dot system, and a stable ironing board — the rounded “nose” end is what makes collars, yokes and sleeve caps easy. A spray bottle of water to re-dampen a shirt that has dried out, or to spot-wet a stubborn crease. And a pressing cloth — a thin cotton or muslin square you lay between the soleplate and the fabric — for anything delicate or dark, where direct heat would shine or mark the cloth. A sleeve board (a miniature board for the inside of a sleeve) is a nice extra for dress shirts but not essential; the edge-of-the-board trick in step three does the same job. You do not need starch to iron a shirt well — it’s a finishing preference for extra crispness, not part of the method.

What heat for which fabric

Here is the rule almost every ironing guide skips: the care label sets the heat, not your guess about the fabric. GINETEX — the body behind the international ISO 3758 care symbols — states it plainly: the maximum temperature “must be selected solely on the basis of the care label and not according to the fibre content.” The iron symbol’s dots cap the soleplate temperature, and that ceiling is binding.

Use the table below as a guide to what the dots usually mean by fabric (mapped by the iron-maker Rowenta), with the GINETEX ceiling for each dot — but if the label and the table ever disagree, the label wins. For other fibres, and for where the sources disagree on silk and polyester, see the full ironing temperature by fabric chart.

A few label symbols are worth knowing on sight — the dots, and the two you must never override:

One dot — iron on low (max 120°C)

Crossed-out iron — do not iron at all

The one-dot symbol doesn’t just mean “low”: GINETEX warns that a steam iron “may cause irreversible damage” on it, and a one-dot symbol with the steam crossed out means iron without steam. And the crossed-out iron is absolute: GINETEX warns that “irreversible changes must be expected if an iron is used,” so a garment marked that way never goes near a hot soleplate, at any setting.

Why insist on the label over the fabric? Because the fabric you think you have is often a blend. A shirt that looks and feels like cotton may be a cotton-polyester mix, and polyester gives way at a temperature cotton shrugs off — so “it’s a cotton shirt, crank it up” is exactly how a blend gets a shiny scorch. The care label is written by the people who know what’s actually in the cloth; the dots are their instruction, not a suggestion. That is precisely why GINETEX ties the ceiling to the label and not to your eyes.

If you are unsure of a shirt, Downy’s advice is the safe default: start on a low setting and increase it until the wrinkles respond, rather than opening on high heat and scorching the cloth.

Iron the shirt, step by step

The order below is one sensible sequence built on the small-zones-first principle. Two things before the first pass: work from a damp shirt — iron a newly washed one while it’s still slightly damp, or spritz a dry one with water, which Eton notes presses smoother and faster — and iron only clean shirts, since Downy warns that pressing over an existing stain can set it permanently.

1. Collar

Unfold the collar flat and iron the underside first, working from the points inward toward the collar stand. Then flip it and finish the top. Starting underneath means any tiny pucker that appears gets pressed out of sight on the side nobody sees, and working from the points inward — rather than along the collar — keeps the tips neat. Don’t press a hard fold into the collar stand; the collar should roll, not crease flat.

2. Cuffs

Unbutton the cuffs and lay them flat. Iron the inside first, then the outside, and press around the buttons rather than straight over them.

3. Sleeves

Sleeves are where a careless press shows most, because a hard crease down the top of a sleeve is hard to undo. Lay each sleeve flat, line up the seam, and position it a few millimetres over the edge of the board so the soleplate never reaches the fold — that’s what stops you ironing an unwanted crease line into it. Smooth from the shoulder seam down toward the cuff in long passes. (Eton and Downy differ on timing here — Eton saves the sleeves for last, Downy irons them before the front and back; do them here or last, your choice, as long as the big panels come after the collar and cuffs.)

4. Yoke and shoulders

Drape the shoulder area — the yoke — over the rounded end of the board and work the iron across it, turning the shirt to reach each shoulder in turn. From here on, on cotton and linen, plenty of steam earns its keep, since steam works best on the thicker fabrics (Rowenta).

5. Front panels and placket

Work each front panel from the side toward the centre, and use the tip of the iron to press around and between the buttons rather than dragging the full soleplate over them. Take the placket — the buttoned strip down the front — slowly, pressing the fabric on either side of each button so the placket lies flat and the buttons sit square; this is the part on show all day, so it’s worth the extra minute.

6. Back

Drape the back over the board in two passes, smoothing from the yoke downward.

7. Finish

Hang the shirt and button the top button straight away so the collar holds its shape, let it cool on the hanger, then turn off and unplug the iron.

When it goes sideways

Even with the right order and heat, a couple of things go wrong often enough to be worth a plan. Here are three quick fixes for the usual ironing mishaps, each of which takes seconds once you know the move rather than re-doing the whole shirt:

• A crease in the wrong place. Don’t try to press it out dry — re-dampen the area with a spritz of water and iron it again.
• Shine on dark cotton. To prevent it, iron the garment inside out and keep the iron moving (Rowenta).
• A delicate you’re nervous about. Drop to the low one-dot setting, use little or no steam, don’t hold the iron in one place, and use a pressing cloth — Rowenta’s protocol for silk, satin, nylon and lace.

Iron safety: burns and scalds

The soleplate runs between 120°C and 210°C — hot enough to cause a burn — so the safety here is not optional.

The bottom line

Two rules carry the whole job. Order: small fixed zones first — collar, cuffs — then the big panels, so later passes are less likely to undo earlier work. Heat: set it from the care-label dots, never from a guess about the fabric, and treat a crossed-out iron as final. Everything else — damp the shirt, steam the thick stuff, keep steam off what the label warns against, hang it the moment you finish — is detail in service of those two.

One boundary worth stating: this is iron heat. For the wash temperature that gets a shirt clean in the first place, that is a different number on a different symbol — see our laundry temperature guide.
