Origami Waterbomb Base Geometry Calculator
Overview
A clean, professional, single-file browser-based application designed for origami enthusiasts and designers. This tool calculates the geometric properties of a Waterbomb Base (preliminary base) based on user-provided paper dimensions. It provides precise measurements for fold lines, expected base width, and diagonal constraints.
Key Features
- Dynamic Calculation Engine: Real-time calculation of diagonal fold lengths, base height, and side width.
- Unit Converter: Seamless switching between inches, centimeters, and millimeters.
- Visual Geometry Guide: Interactive SVG diagram showing where folds occur (Mountain vs. Valley folds).
- Precision Toggle: Option to account for paper thickness (kerf/margin adjustment) for advanced folders.
- Zero-Storage Logic: All calculations are performed in-memory; no data is stored on the client machine.
- Print-Friendly View: A clean summary card output for printing or saving as a reference sheet.
Technical Specification
- Architecture: Single HTML file containing CSS in
<style>and JavaScript in<script>tags. - Frameworks: Pure Vanilla JS, Tailwind CSS via CDN, Lucide-icons for UI elements.
- State Management: In-memory object state. No
localStorage,sessionStorage, orcookies. This ensures compatibility with sandboxed iframe environments. - Responsiveness: Mobile-first, flexbox/grid-based layout. The interface stacks vertically on small screens and expands to a two-column sidebar-main layout on desktops.
UI/UX Design
- Color Palette: Professional SaaS aesthetic: White background (
#FFFFFF), primary action blue (#2563EB), text dark gray (#111827), borders light gray (#E5E7EB), and success green (#16A34A) for calculation results. - Typography: Sans-serif, clean font stack (Inter, system-ui).
- Animations: Subtle transition effects on input focus and card expansion. Results will appear with a smooth opacity fade-in transition (300ms).
- Layout:
- Header: Sticky top header with app title.
- Main Area: Left sidebar for input configuration (Paper size, units, thickness compensation). Right side (or bottom on mobile) for the dynamic SVG visualizer and calculation data table.
Directives for Implementation
- No External Dependencies: Only standard CDNs (Tailwind, Lucide).
- Security: Do not use
eval()orinnerHTMLwith user input. Sanitize all numerical inputs. - Sandbox Compliance: Avoid
alert(),confirm(), orprompt(). All user prompts must be implemented as custom modals (using standard HTML<dialog>element). - Performance: Ensure sub-millisecond calculation time; the logic is basic geometry and should not require asynchronous processing.
- Responsiveness: Use CSS media queries to ensure the sidebar collapses into an accordion on smaller viewports.

Frequently Asked Questions
Everything you need to know about using this application.
What is a waterbomb base in origami?
A waterbomb base is one of the fundamental structures in origami, often referred to as the preliminary base in some traditional texts. It serves as the starting point for countless complex models, including the classic paper waterbomb, flowers, and various animal shapes. Understanding the geometry of this base is crucial for precision folding. By using this calculator, you can determine exactly how your starting paper size translates into the final base dimensions, ensuring your subsequent folds align perfectly without errors.
How does the ratio calculator work for origami?
This tool calculates the geometric relationships based on the standard folding patterns used to create the preliminary base. It takes your starting paper dimensions and computes the required folding lines, angles, and final height, width, and depth of the collapsed base. By providing these specific dimensions, the calculator helps you understand how paper thickness and fold accuracy impact the resulting model size. It is an essential aid for designers and hobbyists looking to create proportional origami art.
Do I need special paper for these calculations?
While these calculations assume a standard, perfectly square sheet of paper, the tool is flexible enough to handle slight deviations. Origami works best with paper that has a consistent square shape, but you can input custom measurements to account for non-standard paper cuts. We recommend using high-quality origami paper or any thin, crisp square paper for the best results. The calculator serves as a planning tool, so you can test how different starting sizes affect the final scale of your project before you commit to cutting or folding expensive materials.
Can this tool calculate multiple bases at once?
Currently, this application is designed to focus on a single waterbomb base calculation at a time to ensure maximum accuracy and clarity. By isolating the calculation, we prevent errors and help you focus on the specific geometric needs of your single model design. You can, however, quickly reset the form to calculate new dimensions for different projects. The lightweight design allows you to generate new calculations instantly, making it perfect for rapid prototyping of complex origami series or multiple model sizes.
