Accurately calculate the exact amount of epoxy resin needed for river tables, coasters, and custom molds. Free, professional-grade tool for woodworkers and DIYers.
AI Generation Prompt
Application Overview
A high-precision, browser-based Epoxy Resin Volume Calculator designed for professional woodworkers and DIY craft enthusiasts. The tool provides a clean, professional interface for calculating the exact volume of resin required for river tables, deep pours, coasters, and art projects.
Core Features
- Multiple Calculation Modes: Dedicated tabs for 'River Table Channel', 'Cylindrical Mold', and 'General Rectangular Pour'.
- Unit Flexibility: Toggle between Imperial (inches) and Metric (cm/mm) systems with instant conversion logic.
- Waste Factor Slider: A dynamic slider (0%–20%) allowing users to add a buffer for mixing loss and surface sealing.
- Live Output Dashboard: Real-time updates showing required volume in Liters, Fluid Ounces, and Gallons as user inputs change.
- Project Export: A 'Copy Results' button that copies a summary of the dimensions and volume to the clipboard.
- Responsive UI: A mobile-first design that adjusts input fields for ease of use on tablets or smartphones while at the workbench.
Technical Specification
- Architecture: Single-file HTML5 document. All JavaScript and CSS are embedded.
- Persistence: No use of
localStorage,sessionStorage, or cookies. The state is maintained entirely in memory. URL parameters may be utilized for state sharing if necessary. - Styling: Tailwind CSS (via CDN) for a modern, 'SaaS-inspired' light-mode aesthetic. Focus on high-contrast typography, rounded corners (large radius), and subtle drop shadows.
- Interactivity: No
alert()orprompt(). All user notifications and result displays will use custom-styled, non-blocking UI components (modals or toast notifications). - Accessibility: High-contrast text, proper ARIA labeling for input fields, and keyboard-navigable form elements.
Design System & Palette
- Background: Crisp white (
#ffffff) or off-white soft gray (#f9fafb) for a clean look. - Primary Accents: A professional 'Tooling Blue' (
#2563eb) for primary action buttons and highlights. - Result Highlights: An 'Emerald' green (
#059669) for the final volume output area to denote success. - Typography: Sans-serif fonts (e.g., Inter or system default) for readability.
- Animations: Subtle transitions (e.g.,
transition-all duration-300 ease-in-out) on input focuses and button hovers. Number updates for volume results should use a gentle fade-in animation.
Developer Directives
- Do not include any branding. The app must remain purely functional.
- Strictly Light Mode. Ensure no dark mode toggles or dark-theme CSS are present.
- Sandboxed Compatibility: Ensure all calculations rely on vanilla JS. Do not attempt to save user data.
- Performance: Keep the total file size under 150KB (including base styles). Use optimized, minified scripts.

Frequently Asked Questions
Everything you need to know about using this application.
How do I calculate resin for a river table?
To calculate the resin needed for a river table, you first need to measure the dimensions of the void (length, width, and depth) in your preferred unit, such as centimeters or inches. You then multiply these dimensions to get the total cubic volume. Our calculator automatically performs these volume conversions and accounts for the specific shape of your river channel. It is essential to subtract the volume of any decorative elements or wood inclusions from the total space to ensure you do not over-purchase epoxy.
Why should I include a waste factor in my calculation?
A waste factor is critical in epoxy projects because it accounts for product loss that occurs during mixing, transfer, and surface sealing. We recommend adding a 5% to 10% buffer to your final calculated volume to prevent running out of material mid-pour. Running out of resin during a pour can cause catastrophic results, such as visible layer lines or incomplete bonding. By using our built-in waste percentage slider, you ensure your project has enough material to cover potential spills, bucket residue, and surface absorption.
Does this tool work for circular or irregular molds?
Yes, our tool includes specialized calculation modes for different project types, including rectangular channels and circular molds. For circular pours, simply input the radius or diameter of your mold to calculate the exact cylindrical volume required for your specific resin thickness. For more complex or irregular shapes, we recommend calculating the primary geometric volume and adding a slightly higher waste factor. This approach ensures that even with non-standard mold shapes, you maintain sufficient resin supply for the entire duration of your project.
What units of measurement are supported?
This calculator supports both metric and imperial units of measurement, allowing for seamless toggling between inches, centimeters, and millimeters. The output can be automatically converted into fluid ounces, liters, or gallons based on your preference. By providing flexible unit support, we ensure that woodworkers, artists, and contractors worldwide can use this tool without manual conversions. Simply select your desired units in the dashboard settings, and all input and output fields will update in real-time.
