Do I need to install anything or use Windows?

No. JobPlumb estimating runs entirely in the browser, so it works the same on Mac, Windows, a Chromebook or an iPad. There is nothing to download and no Windows-only desktop app to maintain.

Is the estimating really free?

Yes. The free plan includes all of the measure tools, scale calibration, a line-item estimate and PDF export for up to two active projects, with no credit card required. JobPlumb Pro ($19/month) adds unlimited projects, the cost-assemblies catalog, branded proposals with online acceptance and Excel export, and it unlocks the field-service Pro features too.

How accurate are the measurements?

Every quantity is computed from real geometry (polygon area, segment length and counts) multiplied by the scale you calibrate against a known dimension on the plan. Nothing is estimated or faked; what you measure is what you get.

On-screen takeoff

Construction takeoff software, in your browser

A takeoff is how you measure quantities off a drawing: square footage, linear feet, counts and volumes. JobPlumb does it on screen, with the scale calibrated to your plan, so every number is true to the sheet and flows straight into a priced estimate.

Scale calibration

Set the scale once, trust every number

Before you measure, trace one dimension you already know (a door, a grid line, a printed scale bar) and type its real length. JobPlumb locks that ratio to the sheet, so every area, length and count after it is true to the drawing.

Works on vector PDFs, scanned drawings and plain images
Per-sheet scale, so a detail and a site plan can use different scales
Re-calibrate any time without re-measuring what you already drew

Takeoff · garage slab1" = 8'

Area measured1,428 sq ft

Four measure tools

Area, linear, count and volume

Trace a polygon for area, a polyline for linear feet, drop markers to count fixtures, or add a depth to turn an area into cubic yards. Every quantity is real geometry multiplied by your calibrated scale, never an estimate.

Area: shoelace polygon area in square feet
Linear: segment lengths summed into linear feet
Count and volume: tallies and area times depth for cubic yards

The workflow

From plan to priced estimate

01
Upload your plans
Drop in a PDF or image of the drawings. Set the scale once by tracing a known dimension, and JobPlumb handles the rest.
02
Measure & price
Click out areas, lengths and counts. Quantities update live and flow straight into a line-item estimate with your unit costs.
03
Send the proposal
Turn the estimate into a branded proposal. Share a link, and your client reviews and accepts online, so you see the moment they do.

Questions

Takeoff, answered

Takeoff software lets you measure quantities (square footage, linear feet, counts and volumes) directly off a construction plan, then turn those quantities into a priced estimate. JobPlumb does this in your web browser: upload a PDF or image of the plans, set the scale, and measure with your mouse.
