Blueprint scale calculator
Use one reliable known dimension to estimate same-plane lengths, rectangular area, or an irregular polygon traced on a local image.
Use one focused tool at each edge of the estimating workflow: calibrate a plan from a known dimension, convert slab measurements into concrete yardage, or check the markup behind a bid. Takeoff is the product that connects those steps and preserves the work.

Three useful previews
These tools demonstrate the path from drawing to quantity to price. They keep the arithmetic visible, but they do not replace the measured source, project assumptions, pricing system, estimate record, or handoff that Takeoff keeps together.

Concrete
Convert measured slab area and thickness into cubic yards, then expose waste and supplier rounding as separate steps.
Bid price
Compare additive-on-direct-cost and sequential-compounding markup without hiding the dollar basis behind each percentage.
A preview, not the product
Each tool answers one narrow question and keeps its formula beside the result. Takeoff connects the drawing, measurements, assemblies, pricing, estimate versions, customer-facing output, and the knowledge you want to reuse.
The calculators do not save drawing context, assemblies, pricing libraries, estimate revisions, or handoff packages. They also cannot confirm field conditions, design requirements, supplier rules, labor productivity, current pricing, or complete contract scope.
