A spice blend scaler recalculates each ingredient when you change the total batch size. Enter your base recipe, set a target amount, and get scaled quantities in both grams and teaspoons/tablespoons for every spice.

How to Use the Spice Blend Scaler
Scaling a spice blend recipe is straightforward with this calculator. Enter each spice with its original gram weight, set your target batch size, and get exact amounts for your new quantity — displayed in grams and easy-to-measure teaspoon equivalents.
Step 1: Enter original recipe amounts
Add each spice with its weight in grams. If you have a recipe in teaspoons, convert using the approximate rule: 1 teaspoon of ground spice = 2.5-3g. Use the presets to load popular blends like BBQ rub or taco seasoning as a starting point.
Step 2: Set target batch size
The original batch size is the sum of all your ingredient weights. The target batch size is how much you want to make. The scaling factor is target ÷ original — for example, making 240g from a 60g recipe is a 4x scale.
Step 3: Read scaled amounts
Results show grams (precise) and teaspoon/tablespoon equivalents for kitchen convenience. For professional use or large batches, always weigh in grams. The teaspoon amounts are approximations based on average spice densities.
Storage and quality tips
Store blended spices in airtight glass jars away from heat, light, and steam. Avoid storing near the stove — repeated heat exposure degrades volatile oils quickly. Label jars with the blend name and date. Most ground spice blends maintain good flavor for 1-2 years.
FAQ
How do I convert between grams and teaspoons for spices?
Ground spices average about 2.5-3 grams per teaspoon, but this varies by density. Light fluffy spices like cinnamon are about 2g per teaspoon. Dense spices like paprika or cumin are about 3g per teaspoon. Whole spices are heavier. This calculator uses average densities for common spices.
Is this spice scaler free?
Yes, completely free. No signup, no account needed. All calculations run in your browser.
How do I scale a spice blend for a larger batch?
Divide your target batch size by the original recipe size to get the scaling factor, then multiply each ingredient by that factor. For example, to triple a recipe: 3x all quantities. This calculator does it automatically — just enter your ingredients and target size.
What is the shelf life of homemade spice blends?
Ground spice blends last 1-2 years stored in airtight containers away from heat and light. Whole spice blends last longer (2-4 years). Add salt only when using, not to the stored blend — it draws moisture and causes clumping. Label with the date so you know when to refresh.
Should I toast spices before blending?
Toasting whole spices before grinding intensifies their flavor by releasing volatile oils. Heat a dry skillet over medium heat, add spices for 1-3 minutes until fragrant, then let cool before grinding. Do not toast pre-ground spices — they burn easily and become bitter.
