About

HomeDecorCalc provides fast, privacy-friendly calculators and short guides for common home improvement projects.

We focus on clear assumptions, practical defaults, and explanations that help you measure and buy materials with confidence.

Each page aims to answer the practical questions: what to measure, what to round up, and what to double-check before you buy. We publish supporting resources and update pages as packaging and conventions change.

What you’ll find here

• Material estimates that match how supplies are sold (bags, boxes, bundles, sheets).
• Notes that explain the formula, unit conversions, and why we round up.
• Simple rules of thumb and checklists that prevent under-ordering.
• Related guides and resources for the next step in planning.

Our principles

• Clarity: show assumptions, units, and helpful defaults.
• Speed: calculations run in your browser, with shareable links.
• Privacy: no accounts, minimal data collection.

Accuracy & limitations

Estimates can’t capture every jobsite condition. Packaging varies, materials settle, waste differs by layout, and local code requirements change by region.

Use calculator results as a starting point, then confirm with your product label, supplier conversions, and installation requirements.

If an assumption doesn’t match what you’re seeing locally, contact us with the product label and context so we can improve the page.

How it works

Every calculator includes notes about units, rounding, and common waste factors. Resources and methodology pages explain the logic behind typical estimates.

How we fund the site

We may show ads to support hosting and ongoing updates. Ads should never prevent you from using a calculator or reading the supporting notes.
