Digging through the basket to read every care label before a dryer cycle is tedious. Enter an item name and the tumble dry symbol you see on its label, row by row, and the tool counts how many items can go in, names the ones to pull out, and works out the lowest heat level that applies if you run the whole load together.
The symbol system follows ISO 3758:2023 from the International Organization for Standardization. In that system a symbol stands for the most severe treatment that does not cause irreversible damage, and dots mark a temperature level. The heat level for a mixed load is the smallest dot count you entered, because the most restrictive item governs the load. Items marked with a cross are classed as items to pull out (as of October 2026).
Nothing here is decided from the fabric. The label symbol is the reference, and because the Celsius values behind drying dots are not confirmed in an authoritative source, dot counts are never converted to temperatures. Drying time, detergent dosing and wash frequency are not covered. The value printed on your product label is the reference - follow the label and the manufacturer guidance first.
Frequently Asked Questions
The Celsius values behind tumble dry dots are not confirmed in an authoritative source, so the tool compares dot counts only and shows no temperature. Maximum ironing temperatures are published per system and covered by a separate tool.
It is the smallest dot count you entered, because the most restrictive item applies to the whole load. Items with no dots shown and items left as unknown are excluded from that comparison.
That is not advised. The tool takes label symbols rather than fabric types. If an item has no label or you cannot find the symbol, leave it as unknown and check the manufacturer guidance.
