How to Read Clothing Care Labels: Washing, Drying and Ironing Symbols

A plain-English guide to the washing, bleaching, drying, ironing and dry-cleaning symbols on clothing care labels, and what each one means.

Which fabric suits the day?

Choose the conditions you are dressing for and see which fibres tend to work best, and why.

Recommended fibre

Linen or lightweight cotton

  • Linen is the most breathable common fabric. It absorbs moisture and dries quickly.
  • Lightweight cotton is softer and creases less than linen.
  • Avoid heavy synthetics, which hold heat and moisture against the skin.
Compare cotton, linen and wool

Meet the fibres

Eight fibres make up most of what you own. Here is what each one does best, and the one thing to watch.

Plant fibre

Cotton

Soft and absorbent, grown in the boll around the cotton plant seeds. Best for everyday basics and bed linen.

Stronger when wet than dry, so it washes well.

Plant fibre

Linen

Made from flax stems. Crisp, cool and very breathable. Best for hot-weather shirts and trousers.

Creases heavily and softens with every wash.

Animal fibre

Wool

A protein fibre from sheep fleece. Warm, elastic and odour resistant. Best for knitwear, coats and suits.

Heat, water and rubbing make it felt and shrink.

Animal fibre

Cashmere

The fine undercoat of cashmere goats. Very soft and light for its warmth. Best for knitwear and scarves.

Pills easily, so wash gently and comb pills away.

Animal fibre

Silk

A smooth filament from silkworm cocoons. Lustrous and light. Best for blouses, scarves and linings.

Prolonged sunlight and harsh detergents can damage it.

Synthetic

Polyester

A durable polymer that dries quickly and resists wrinkles. Best for sportswear, outerwear and blends.

Absorbs very little water, so it can feel clammy.

Synthetic

Nylon

The first fully synthetic fibre, introduced in the late 1930s. Strong and abrasion resistant. Best for hosiery and jackets.

Sensitive to high heat in the wash and dryer.

Semi-synthetic

Viscose

Regenerated cellulose from wood pulp. Soft with a fluid drape. Best for dresses, blouses and linings.

Weakens when wet, so handle it gently.

Fabric quick reference

How the most common clothing fibres compare at a glance. Always follow the care label on your own garment.

Ratings are general guidance. Weave, finish and blends change how any real fabric behaves.

Care label symbols

Five shapes cover almost every care label. Learn them once and every label becomes readable.

  • Washing

    A number shows the maximum water temperature in degrees Celsius. A hand means hand wash only.

  • Bleaching

    Empty means any bleach. Two diagonal lines mean non-chlorine bleach only.

  • Drying

    A circle inside means tumble drying is allowed. Other lines show line drying, drip drying or drying flat.

  • Ironing

    Dots show the heat: one is low, two are medium and three are high.

  • Professional cleaning

    Empty means dry cleaning is allowed. A letter shows the solvent type to use.

A cross through any symbol means do not do that.

Size charts mix both units. Type in either box and the other updates.

Cost per wear

Divide the price by the number of times you expect to wear it.

Enter a price and a number of wears.

Quick answers

Short answers to common clothing questions. Follow the links above for the full detail.

What is the most breathable fabric?

Linen is generally the most breathable common clothing fabric, followed by lightweight cotton. Loose weaves and open knits breathe better than tightly woven or coated fabrics, whatever the fibre.

How often should I wash jeans?

There is no fixed rule. Many people wash jeans after several wears, or when they are dirty or sweaty, because less washing protects colour and fit. Wash them inside out in cold water.

Why do clothes shrink in the wash?

Heat, water and agitation let fibres relax and tighten. Cotton and wool shrink the most. Washing in cool water, drying gently and choosing pre-shrunk fabric all reduce the risk.

What does GSM mean on a t-shirt?

GSM stands for grams per square metre and measures fabric weight. As a rough guide, lightweight t-shirt fabric is under about 150 GSM, midweight is around 150 to 200, and heavyweight is above that.

Is polyester bad for your skin?

Polyester is not harmful in itself, but it absorbs little moisture and can feel hot and clammy. If you have sensitive skin or an allergy, natural fibres may be more comfortable, and washing new clothes before wearing them helps. Speak to a healthcare professional about any skin condition.

How can I tell if a garment is well made?

Check that seams are straight and even, stitches are small and secure, patterns line up at the seams, buttons are firmly sewn and the fabric springs back when gently stretched. The fibre content and fabric weight on the label also give clues.

Terms worth knowing

The vocabulary behind labels, size charts and fabric descriptions.

Warp and weft
In woven cloth, warp yarns run lengthwise on the loom and weft yarns pass across them.
Selvedge
The self-finished edge of woven fabric, which stops the cloth from unravelling.
GSM
Grams per square metre. A measure of fabric weight, where a higher number means heavier cloth.
Thread count
The number of threads woven into one square inch of fabric, used mainly for bed linen and shirting.
Staple length
The length of individual fibres in cotton or wool. Longer staples spin into smoother, stronger yarn.
Hand
How a fabric feels when touched, including its softness, stiffness and drape.
