Baker's Percentage Recipe Scaler
Overview
A professional-grade, browser-based tool for calculating baker's percentages, scaling dough recipes, and managing hydration levels. Built for home and artisan bakers, this tool provides a clear interface for high-precision dough formulation.
Core Features
- Dynamic Ingredient List: Users can dynamically add, remove, and rename ingredients (e.g., Bread Flour, Whole Wheat, Water, Salt, Instant Yeast, Levain).
- Total Weight or Flour-Based Scaling: Choose to scale the entire recipe by total final dough weight or by defining a specific weight for the master flour component.
- Real-Time Baker's Percentage: Automatically calculates and updates the percentage of each ingredient relative to the total flour weight (which is pinned at 100%).
- Instant Hydration Tracking: Provides a live readout of total dough hydration, making it easy to hit specific targets.
- Unit Conversion Toggle: Seamlessly switch between Metric (Grams/Kilograms) and Imperial (Ounces/Pounds) inputs.
UI Layout
- Header: Minimalist title bar with a clean font, featuring a "Reset" button for clearing the form.
- Configuration Panel: A prominent area to set the "Total Dough Weight" or "Flour Weight" and choose units.
- Ingredient Table: A clean, spreadsheet-like interface where users input ingredient names, weights, and see calculated percentages in adjacent columns.
- Summary Section: A fixed-bottom or sticky sidebar showing a recipe summary (Total Dough Weight, Total Hydration, Total Flour).
Design & Aesthetic
- Color Palette: Use a clean, professional SaaS aesthetic.
- Primary Background: #FFFFFF
- Card/Surface Color: #F8FAFC
- Text Color: #1E293B (Slate)
- Primary Accent (Buttons/Highlights): #4F46E5 (Indigo)
- Borders/Dividers: #E2E8F0
- Animations: Soft fade-in animations when new ingredient rows are added. Micro-interactions (hover states) on buttons for a responsive feel.
- Typography: Clean, sans-serif, high-legibility font stack (Inter or system-ui).
Technical Constraints (Mandatory)
- Single File: All HTML, CSS, and Vanilla JavaScript must be contained within one file.
- No Storage: Do not use
localStorage,sessionStorage, or cookies. Everything must remain in-memory. - Responsive Design: Use CSS Flexbox and Grid to ensure the table and configuration panels stack cleanly on mobile devices and expand on desktops.
- Dependencies: Use standard CDNs for CSS frameworks (e.g., Tailwind CSS) and lightweight icon libraries (e.g., Heroicons) if needed. Avoid heavy frameworks.
- Compatibility: Ensure the app functions perfectly inside a sandboxed iframe without access to external origins or storage APIs.

Frequently Asked Questions
Everything you need to know about using this application.
How do you calculate baker's percentages?
Baker's percentage is calculated by dividing the weight of an individual ingredient by the weight of the total flour in a recipe and multiplying the result by 100. This method allows bakers to see the proportions of a recipe independent of the actual final loaf size. By establishing the total flour weight as 100%, every other ingredient is represented as a relative percentage. This makes it simple to compare formulas and scale recipes up or down without changing the final texture or properties of the dough.
Why use baker's percentages for bread?
Using baker's percentages provides a universal language for bread baking. It allows bakers to analyze the hydration, salinity, and enrichment levels of a formula at a glance, ensuring consistency across different batch sizes. Whether you are scaling up to bake for a professional production or scaling down for a single loaf at home, baker's percentages ensure the ratio of water to flour remains exact. This prevents the common errors associated with calculating ingredient adjustments manually.
Can I adjust hydration percentages with this tool?
Yes, this tool allows you to manipulate hydration percentages directly. By adjusting the weight of the water ingredient, the hydration percentage automatically updates in real-time, allowing you to hit your specific target hydration for different types of breads. Changing the hydration percentage is essential for mastering different styles of bread, from stiff pizza doughs to high-hydration sourdough boules. Our interactive calculator updates all values instantly, providing the correct flour and water weights required to maintain your desired hydration level.
Is this tool suitable for professional bakers?
Absolutely. This tool is designed with professional workflows in mind, offering precise calculations for ingredient management and consistency in the bakeshop. It provides a clean, responsive interface that works well on tablets and mobile devices in a kitchen environment. While simple enough for home bakers, the calculation engine handles complex additions like levain and enrichment ingredients with high accuracy. It acts as a reliable reference point for adjusting formulas quickly during the production process without the need for manual pen-and-paper math.
