TODYE
The craft of color — fabric dyeing, natural dyes, and the calculators behind every batch.
From converting yarn counts and weighing a fabric's GSM to gauging a batch's eco-impact, building a depth-of-shade recipe, costing out a job, and mixing custom colors by parts, ToDye pairs free hands-on dyeing calculators with practical guides and a richly illustrated museum. Dye smarter, color truer.
Dyeing Tools & Calculators
Free tools for the dye studio — yarn count converter, fabric GSM calculator, dyeing eco-impact calculator, dye recipe calculator, dye cost estimator, and color mixing calculator.
Yarn Count Converter
Convert a yarn count between tex, dtex, denier, the metric count (Nm), and the cotton count (Ne) — every pairing routes through a common tex base for a clean, consistent figure
Fabric GSM Calculator
Weigh and measure a swatch to get its weight in grams per square metre (GSM), plus the ounces-per-square-yard equivalent — characterise any cloth before you dye it or buy it
Dyeing Eco-Impact Calculator
Estimate the water, energy, carbon, and chemical load of a dye batch from the fabric weight, dye process, and liquor ratio — and see how a tighter bath or a natural dye changes the picture
Dye Recipe Calculator
Turn the depth-of-shade method into a ready-to-weigh recipe — dye, water, salt, and soda ash for a fibre-reactive immersion bath, from your fabric weight, shade percentage, and liquor ratio
Dye Cost Estimator
Price out a dye batch — dye used and its cost, plus auxiliaries and labour — to get the total and the cost per kilogram of fabric, from your fabric weight, shade percentage, and dye price
Color Mixing Calculator
Mix dye colors by parts — enter a ratio like 1:1:2 and a batch weight, and get the exact proportions and weigh-out grams for each color, so you can reproduce a custom shade batch after batch
Dyes & Textiles Museum
Wander an immersive museum of the dyes and fibers that give cloth its color — ancient natural dyes like indigo, madder, and cochineal alongside modern fiber-reactive, acid, and disperse dyes, the world of natural and synthetic fibers, mordants and auxiliaries, and the craft of techniques from shibori to vat dyeing, each in its own gallery, so you can get to know the stories behind every color: how each dye came to be, what makes it bond to fiber, and the role it plays in shaping how we color the textiles around us.
Tour the museum →From the Journal
Fresh guides on natural and synthetic dyes, indigo and shibori, mordants, color mixing, and eco-friendly dyeing, plus practical tips for prepping fiber, building recipes, troubleshooting shades, and getting an even, lasting color in every batch.
