Spice Blend Ratio Calculator
Scale a spice blend to any total weight while keeping the parts in ratio — mix a house blend in exactly the quantity you need.
How it works
Grams per part = total weight ÷ sum of parts · Each spice = its parts × grams per part
A blend recipe written in “parts” is a ratio, not a fixed quantity — so it scales to any batch size. Add up all the parts, divide your desired total by that sum to get grams per part, then multiply each spice’s parts back up. This lets you mix a tiny test batch or a full jar from the same recipe, and swap the total weight without touching the proportions.
Worked example
A 4:2:1:1 blend has 8 parts total. For 48 g of finished blend, each part is 48 ÷ 8 = 6 g, so you weigh out 24 g base, 12 g of the second spice, 6 g of the third and 6 g of salt.
Frequently asked questions
What is a “part”?
A part is any unit of measure as long as you use the same one throughout — grams, teaspoons, scoops. Because a blend is defined by ratio, the part only sets the proportions; this calculator converts those parts into grams for your chosen total.
Can I use volume (teaspoons) instead of weight?
You can keep the ratio in teaspoons, but different spices have very different densities, so a teaspoon of paprika weighs less than a teaspoon of salt. Weighing in grams gives the most consistent, repeatable blend batch to batch.
How much salt should a blend have?
That depends on how you use it. A finishing or all-purpose seasoning might be a quarter salt by weight; a rub added to already-salted meat may have little or none. Keep salt as its own part so you can dial it independently of the aromatics.
