How to read it

One dot in the tumble-drying circle limits the dryer to reduced heat. Two dots allow the normal setting, and a cross through the symbol means no tumble drying.

Also searched as: tumble dry one dot.

Where a garment's own label or its manufacturer says otherwise, that takes precedence.

Differences by country or standard

The dots mean the same order of heat everywhere, but the guides name and limit them differently. GINETEX, the international body behind the symbols, calls two dots the normal process at up to 80°C and one dot a mild process at up to 60°C. The Canadian government's guide calls two dots medium heat, up to 65°C, one dot low heat, up to 55°C, and adds a third dot for high heat, up to 75°C.

Australia's consumer regulator, the ACCC, gives the international limits as the dryer's exhaust temperature: at most 60°C for one dot and 80°C for two.
