About MyHouseLogic

Global home, construction, renovation and DIY calculators — plan, measure and calculate real projects in metric or imperial.

Our Mission

MyHouseLogic exists to help every homeowner make better decisions about their home. Whether you're painting a bedroom, pouring a patio or weighing up solar panels, the same question comes first: how much will I actually need? Guessing is wasteful — overbuying ties up material, under-buying stalls the job half-finished. We believe the numbers should be free, instant, and honest about what they assume.

Home improvement advice tends to sit at one of two extremes: glossy inspiration with no maths, or trade software built for estimating departments. We built the middle path — tools that are friendly enough for a first-time DIYer and rigorous enough for a working pro. Every formula traces to published industry reference tables, every assumption is printed on the page, and the plain-English answer always comes before the technical detail. No paywall, no signup, no app to install.

How We Build Calculators

Every calculator on MyHouseLogic follows the same editorial process. We start with the relevant industry standards — ASTM International, ANSI, TCNA Handbook, NEC, UPC, IRC — and build every formula from published reference tables. We test each calculator against real-world projects: known pours, known sheet counts, known tile layouts. If our number doesn't match the as-built count, we fix the formula before publishing.

Each tool follows the same friendly structure on the page. First it tells you what the calculator does and what you'll need before you start. Then you enter your measurements and read your results — with a plain-English explanation of what each result means, the assumptions behind it, and practical next steps. For those who want to verify the maths (we love those readers), every formula is documented in full, and a worked example runs a real project end to end. Transparency is a feature, not a vulnerability.

Editorial Independence

MyHouseLogic does not accept paid placements in our calculator results, sponsored reviews of products, or "advertorial" content disguised as editorial articles. Our calculators are math — they have no opinions and accept no sponsorships.

When we publish a long-form article that references specific products (a particular thinset brand, a type of curing compound, a model of water heater), those references are based on industry standards and common usage — not on payments from manufacturers. If we ever accept a sponsored article in the future, it will be clearly labeled as "Sponsored" at the top of the content.

Roadmap: What's Coming

MyHouseLogic launched in 2026 with five foundational calculators covering the most common home projects: concrete, drywall, tile, paint, and garden materials. In August 2026 we added the Solar Panel System Sizing Calculator as the first tool in our Roofing & Solar category. In September 2026, four new field guides — roof measurement, solar panel count, electrical service load, and water heater sizing — opened the Roofing & Solar and Home Maintenance guides, bringing the library to twenty-four, and the Roofing Materials Calculator became the site's seventh tool: footprint and pitch in, a full shingle order out. The Electrical Service Load Calculator followed as the eighth: both NEC Article 220 methods in, calculated amps and a suggested service size out. The Water Heater Sizing Calculator is the ninth: the peak-hour worksheet in, the First Hour Rating to shop for out — plus a tankless unit’s honest GPM at winter temperature rise. The Attic Insulation Calculator is the tenth: climate zone and existing depth in, the R-value gap out as settled inches, bags to blow or batt packages to buy — and the attic insulation guide brought the field guide library to twenty-five. The Deck Lumber Calculator is the eleventh: footprint and framing in, the full order out — joists, rim, beam and posts from the IRC span tables, then deck boards, screws or clips — and its takeoff guide brought the library to twenty-six. The Pipe Volume Calculator is the twelfth: material and nominal size in, the true bore out — gallons held, water weight, the hot-water wait and flow velocity — and the pipe volume guide brought the field guide library to twenty-seven. Six more field guides followed that month — flooring quantities, wire sizing, drain-waste-vent, paver quantities, irrigation run times and attic ventilation — bringing the library to thirty-three. In October 2026 the site went global: the calculators became metric-first with a one-tap Imperial toggle, cost estimation was removed entirely so every tool answers a quantity question, and eighteen new calculators — gravel, bricks, blocks, mortar, render, stairs, pavers, retaining walls, gutters, wallpaper, flooring, pools, ponds, rainwater, fences, raised beds, workshop lighting and solar batteries — brought the total to thirty. Seventeen new guides opened a Homes Around the World collection — tatami room sizes, compact Japanese homes, Chinese apartment renovations, UK bathrooms, South African building practice and timber sizes worldwide — bringing the library to fifty, and eight project plans now sequence the tools the way the work actually happens. The site is organised around the major parts of a home — Concrete & Building, Garden & Outdoor, Roofing & Solar, Painting & Walls, Flooring, Pools & Water, Home Systems, Garage & Workshop, Kitchen & Bathroom, and Homes Around the World. On the roadmap, in rough priority order:

• Wire size and conduit fill calculators (NEC Chapter 9) — the wire sizing guide is live.
• Drain, waste and vent (DWV) sizing calculator — the DWV field guide is live.
• Irrigation design calculator (sprinkler zones, head counts) — the run-time guide is live.
• Kitchen and bathroom planning tools — splashback areas and wet-room layouts.
• More regional guides for the Homes Around the World collection.

No dates promised — a tool ships when its numbers test clean against real projects, and each one appears on the Tools page the day it goes live. The guides follow the same rule.

Editorial Team

MyHouseLogic is maintained by a small editorial team with backgrounds in residential construction, civil engineering, and technical publishing. We do not publish individual author bios on every article because most of our content is collaboratively edited and reviewed by multiple team members. The "MyHouseLogic Editorial" byline represents the collective work of the team, not a single author.

Technology & Performance

MyHouseLogic is built as a static website using only standard HTML, CSS, and vanilla JavaScript. We use no frameworks (React, Vue, Angular), no build tools (Vite, Webpack), no third-party scripts beyond Google Fonts (optional). Every page is delivered as raw HTML/CSS/JS, weighing under 50 KB total. Our cumulative layout shift (CLS) is 0, our largest contentful paint (LCP) is under 1 second on a 4G connection, and our total blocking time (TBT) is negligible.

This performance philosophy is intentional. Home projects happen in real conditions: in the garden on a sunny afternoon, on a ladder with one hand, at the store aisle comparing bag counts, in a basement with one bar of signal. A 5-megabyte JavaScript bundle that takes 8 seconds to load is useless in all of them. We optimize for the worst-case user — the DIYer on an older phone at the far end of the garden.
