Split a total amount of a mix into its materials from a ratio. Enter the total and a ratio such as 3:2:1, and the tool shows each material’s amount and share of the whole — useful for pigments, casting mixes, dye baths, slip and glazes. This is an approximate calculator, not a quote; follow the manufacturer’s ratios and measure accurately, since small errors matter in chemistry and curing.

How to Use the Craft Material Ratio Calculator
Enter the total amount, an optional unit label, and a ratio such as 3:2:1. Press Split amounts to see each material amount and its share of the mix.
What it accounts for
Parts are summed, then each material is the total times its part divided by the parts total.
Percentages show each material’s share of the whole.
Two or more parts are supported, with decimals allowed.
Measuring accurately
For resins, dyes and pigments, small ratio errors change how a mix cures or sets. Weigh by parts rather than guessing, and follow the manufacturer’s recommended ratio. Treat the result as an approximate guide, not a quote.

Results are approximate guides only, not a quote. Follow the manufacturer’s ratios and measure each part accurately, because curing and setting depend on exact proportions.
