Explanation

What do laundry symbols mean, and how do you recognize them automatically?

Care symbols are based on five basic shapes: a washtub (washing), a triangle (bleaching), a square (drying), an iron (ironing), and a circle (dry cleaning); dots indicate the temperature, and a cross means do not do it. For an online store, you can recognize them automatically by taking a photo of the care label: Photopilot reads the symbols and adds them to the item as care instructions.

The five basic care symbol shapes

The wash label, known in English as the care label, uses the same symbols internationally (ISO 3758, managed in Europe by GINETEX). The order on the label is always the same: washing, bleaching, drying, ironing, and professional cleaning.

Three rules make almost every symbol easy to read. A cross through it means do not do it. Dots indicate temperature: one dot is low, two dots are medium, and three dots are high. Lines under a symbol mean gentler treatment: one line is a delicate cycle, two lines are an extra-gentle cycle, such as for wool.

A label has at most one symbol per category. A garment therefore cannot have both 30 and 40 degrees; this is useful to know when you have labels read.

All common care symbols and what they mean

The table below describes the symbols you see on almost every clothing label. Also use the description in the second column as text on your product page, so customers using a screen reader and search engines can read the care instructions.

Not sure? Wash at the lowest temperature shown on the label and skip the dryer. Shrinkage cannot be reversed.

Why care instructions belong on your product page

Before buying, customers want to know whether a sweater can go in the washing machine or needs to be dry cleaned. Clear care instructions on the product detail page (PDP) reduce customer service questions and returns from customers who damaged an item in the wash.

Do not add the symbols only as an image; add them as text as well, for example: wash at 30 degrees, do not bleach, do not tumble dry, iron at low temperature. Search engines and AI assistants read that text, not images.

With care instructions as a property, you can also filter: everything that can go in the washing machine, or everything that does not need ironing. In Shopware, Photopilot adds the care instructions as a property on the product page and, if you want, as a filter.

Automatically read care labels from a photo

Manually typing care symbols for thousands of items is error-prone work. Automatic reading uses an image recognition model trained on photos of real care labels: it finds each symbol on the label and shows how confident it is for each one.

Photopilot uses its own detection model for this, recognizing common symbols such as 30 and 40 degrees, hand wash, do not wash, do not bleach, non-chlorine bleach, low and medium tumble-dry temperature, do not tumble dry, iron at low or medium temperature, do not iron, dry clean with P, and do not dry clean.

Because a label has only one symbol per category, the symbol with the highest confidence wins in each group. If the model detects 30 degrees with high confidence and 40 degrees with low confidence, only 30 degrees remains. For symbols the model does not recognize or that you want to correct, you select the right one manually from an overview.

The material label is read separately: AI extracts the composition from it, such as 95% cotton and 5% elastane. If you scan a label again, the new result replaces the previous one.

The Item Info scanner in the iPhone app

In the Photopilot app for iPhone, first scan the product barcode. Then photograph the material label and the care label. Care symbols are recognized live in the viewfinder, with a percentage for each symbol showing how confident the recognition is.

After the photo, the server confirms the recognition. Any symbol the server does not confirm remains visible with a subtle uncertainty indicator, so you can check or adjust it with one tap. The data is added directly to the item you scanned.

That turns reading labels into something you do while unpacking a delivery, instead of a separate desk job.

  • 1. Scan the item's barcode
  • 2. Photograph the material label: AI reads the composition
  • 3. Photograph the care label: symbols are recognized in real time
  • 4. Review uncertain matches and save them to the item

Other sources, and when scanning is not needed

Scanning is not always necessary. Many brands already provide material details and care instructions digitally via Fashion Cloud or in the product data from your ERP. Photopilot then copies that data automatically, so you only scan the products where nothing comes in.

If you sell only a few items, or mostly accessories without a care label, manual entry is fine. And if there is any doubt about a symbol, the physical label in the garment always takes precedence, not the webshop text.

FAQ

Frequently Asked Questions

What do the dots on a laundry symbol mean?

Dots indicate the temperature. For ironing, one dot means a maximum of 110 °C, two dots 150 °C, and three dots 200 °C. For tumble drying, one dot means low temperature and two dots mean normal temperature.

What does a triangle on a care label mean?

The triangle is about bleaching. An empty triangle means all bleaches are allowed, two diagonal lines mean non-chlorine bleach only, and a crossed-out triangle means do not bleach.

What does a square with a circle inside mean?

That is the tumble dryer symbol. One dot means low temperature is allowed, two dots mean normal temperature, and a crossed-out symbol means the item must not be tumble dried.

What does the P in a circle on a clothing label mean?

The circle indicates professional cleaning. A P means the dry cleaner may use common solvents; an F means hydrocarbon solvents only; and a W means professional wet cleaning.

What do the lines under the washtub mean?

Lines indicate a gentler treatment. One line means a delicate cycle; two lines mean an extra gentle cycle, such as for wool.

Can an app recognize care symbols from a photo?

Yes. The Photopilot app for iPhone recognizes care symbols live in the viewfinder and shows the confidence level for each symbol. The data is then added directly to the scanned item.

How do I add care symbols to my online store?

As both an image and text, for example wash at 30 degrees, do not tumble dry. In Shopware, Photopilot can add the care instructions as a property and as a filter.

Which care symbols does Photopilot recognize automatically?

Common symbols, such as 30 and 40 degrees, hand wash, do not wash, do not bleach, non-chlorine bleach, tumble dry low and medium, do not tumble dry, iron low and medium, do not iron, and dry clean. You select other symbols manually from an overview.

Do I need to scan care labels if I use Fashion Cloud?

Often not. If brands provide material and care instructions through Fashion Cloud, Photopilot imports them automatically. You only scan items for which no data comes in.
