About DecorTools
DecorTools is dedicated to providing homeowners, interior designers, DIY enthusiasts, and trade professionals with free, reliable, and mathematically accurate calculation tools.
Our Mission
Home renovation and interior decorating should be creative and exciting, not derailed by confusing unit conversions, material shortages, or unexpected package costs. We created DecorTools to eliminate guesswork by turning standard architectural trade formulas into simple, instant calculators.
Why Our Tools Stand Apart
Real Mathematical Formulas
No arbitrary approximations or black-box guesses. We document every formula and step-by-step calculation directly on each page.
Active Unit Conversion
Switching from Imperial to Metric mathematically recalculates existing measurements into accurate meters and centimeters.
Trade Packaging Logic
Calculations account for real purchasing constraints: round-up logic for full cans, flooring boxes, drywall sheets, and wallpaper rolls.
Privacy & Instant Speed
100% client-side calculations. No tracking of personal home dimensions, no accounts, and no paid subscriptions.
