Every time I needed to calculate concrete yardage, drywall sheet counts, or room paint coverage, the top search results were either covered in intrusive display ads or locked basic PDF estimates behind a monthly SaaS paywall.
So I built MeasurePath (getcoatpath.com) — a fast, ad-free spatial planning studio and construction calculator toolkit that runs directly in the browser with zero tracking.
What It Includes:
- Interactive 2D/3D Studio: Map out a roof, exterior walls, or interior flooring in 2D and 3D, deduct doors and windows, and turn real measurements into material takeoffs.
-
Trade & Material Calculators:
- Concrete Calculator (Cubic yards, cubic feet, and 40/60/80 lb bag counts)
- Concrete Slab Cost Calculator (Ready-mix, reinforcement, and labor per sq ft)
- Drywall Calculator (4x8, 4x10, and 4x12 sheet counts with opening deductions)
- Roof Pitch Calculator (Rise/run to pitch, angle in degrees, and rafter multipliers)
- Paint & Primer Calculator & Exterior Paint Calculator
- Free Construction Estimate Generator: Build an itemized material + labor takeoff ledger saved locally on your device and print a clean PDF quote with no login required.
Tech Stack
Built with plain HTML, CSS, and vanilla JavaScript alongside an interactive 2D/3D canvas viewport, using an architectural drafting-paper design system (--mp-* tokens) and tabular monospace typography for ledger precision.

Interesting project i like it keep up the work👍👍
very visual i like i never seen calculators have this aspect of 3d/2d
This is so impressive especially for a free website
