Complete Guide to RecipeResize.com

Master ratio scaling for any application - from cooking to construction

What This App Does

RecipeResize.com is a universal ratio scaling calculator that works for ANY proportional mixture - not just food recipes. Whether you're cooking for a crowd, mixing hydroponic nutrients, or batching concrete, this tool ensures perfect proportions every time.

🔢 Ratio Scaling

Scale any recipe up or down while maintaining exact proportions

📏 Unit Conversion

Convert between different measurement systems instantly

💾 Save Presets

Store your favorite mixtures for quick access

🖨️ Print Recipes

Generate clean, printable recipe cards

How It Works

Enter your original recipe ingredients, their quantities and the unit of measurement. Once you lock the proportions, when you change the quantity of any ingredient, the rest of the recipe will automatically scale while keeping the same proportions. You can also switch between metric and imperial units as needed, and save your scaled recipes as presets for future use.

🍳 Food & Cooking Applications

Basic Cooking Example: Pancakes for 8 People

Tip: Enter the Serving Size as your first row. After locking, adjusting the serving size will cause the other ingredients to scale automatically.

  • Yeast: 1% (5g)

Unit Conversion Examples

  • Metric to Imperial: 250g flour = 8.8185 ounces
  • Liquid conversions: 500ml milk = 2.11 cups = 16.9 fl oz
  • Small measurements: 5ml vanilla = 1 teaspoon

⚡ Advanced Tips & Tricks

Master Row Technique

  1. Set your base: Enter your original recipe quantities
  2. Lock it: Click "Lock Recipe" to fix proportions
  3. Scale it: Change any ingredient quantity to automatically scale all others
  4. Save it: Save as a preset for future use

Unit Conversion Strategy

  • Weight to Volume: Use density values for accurate conversions
  • Metric to Imperial: Convert entire recipes at once
  • Small Batches: Scale down for testing before large batches

Common Pitfalls to Avoid

  • Don't round prematurely: Keep precision until final measurement
  • Check units: Ensure all ingredients use compatible units
  • Consider losses: Add 5-10% extra for mixing losses
  • Test small first: Always test new ratios in small batches

Pro Tips

  • Save base ratios: Store ingredient ratios as percentages
  • Use descriptive names: Include units in ingredient names
  • Document sources: Add notes about where recipes came from
  • Batch tracking: Include date and batch numbers in presets
