How to read it

A crossed-out tumble-drying symbol means the item is not to be dried in a tumble dryer. The same square with a cross but no circle inside means something wider in the Canadian guide: do not dry at all, used together with the do-not-wash symbol.

Also searched as: crossed out circle in square, no tumble dry.

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

How well people know it

The drying symbols are among the least understood. In a survey of 6,000 people in six European countries, carried out by IPSOS for GINETEX in December 2016, 45% of people did not know what the drying symbol means.
