Work out dye quantity instantly with clear inputs, formula shown and shareable results.
Dye is dosed as a percentage of the dry fabric weight, called depth of shade, and the bath volume follows from the water to fabric ratio. Because dye is measured against fabric weight rather than water volume, the same shade is repeatable in any size bath.
Dye quantity
dye grams = fabric weight x depth of shade percentage
Bath volume
litres = fabric kg x water to fabric ratio
dye grams = fabric weight x depth of shade percentage. Dye is dosed as a percentage of the dry fabric weight, called depth of shade, and the bath volume follows from the water to fabric ratio.
Because dye is measured against fabric weight rather than water volume, the same shade is repeatable in any size bath.
Enter dry fabric weight, depth of shade, water to fabric ratio. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
