Measure off a drawing PDF

Set the scale once against a dimension you can read, then measure runs, areas and counts. Export a materials list. Nothing is uploaded.

Floor plans, site plans, elevations. A single sheet works best.

How it works

Step 1

Calibrate against a real dimension

Click each end of a dimension printed on the sheet and type what it says. The scale is never guessed from a scale bar, which can be redrawn or reprinted at the wrong size.

Step 2

Check the scale it reports

It is shown back as an architectural scale you recognize: 1/4" = 1'-0". If that is not what the sheet says, recalibrate before measuring anything.

Step 3

Measure and export

Runs, areas and counts, each labeled. Like items total together into a materials list you can download as CSV.

What it measures

Three kinds of quantity

01

Linear runs

Baseboard, trim, pipe, conduit, kerb. Click along the run; the segments total as you go and report in feet and inches.

02

Areas

Flooring, roofing, paint, slab. Click around the outline, including L-shapes and cut-outs. Perimeter comes with it.

03

Counts

Outlets, fixtures, doors, sprinkler heads. Click each one. Waste allowance is never applied to a count, because you cannot order 11.5 outlets.

04

A materials list

Like labels total together, waste is applied to material only, and the scale used is written into the export so the numbers can be checked later.

Questions

How accurate is it?

As accurate as your calibration and your clicking. Calibrate against the longest dimension on the sheet: a click error of two points on a 20-foot dimension is a 1% error on everything, while the same error on a 3-foot dimension is 7%. The tool refuses to calibrate against anything shorter than a few points for that reason.

Why not read the scale off the sheet?

Because a scale bar can be redrawn at the wrong size, and a "1/4 inch = 1 foot" note survives the page being printed to a different paper size. The note then says one thing and the geometry says another. Asking you to click a dimension is slower and right more often.

Does it work on a scanned drawing?

Yes, because measuring is geometric and does not need a text layer. You still have to read the dimension yourself to calibrate, which you would anyway.

Can I measure on more than one sheet?

You can move between sheets, but the scale is per sheet and so is the calibration. Recalibrate when you change sheet, because sheets in one set are frequently drawn at different scales.

Is this a replacement for Bluebeam?

No. Bluebeam does markup, collaboration, overlays and much more, and a professional estimator doing this daily should use a professional tool. This is for the person who needs three quantities off one sheet without buying a license or uploading a confidential drawing.

Is the drawing uploaded?

No. Sets are often confidential before bid. The sheet is rendered and measured in this tab and never sent anywhere.
