PDF measurement and calibration
Calibrate a PDF drawing to its real-world scale, then measure distances, areas, angles, and counts. Export quantities for takeoff and estimating.
A drawing is only useful if the dimensions can be trusted. Measuring from a PDF without calibration produces numbers that look precise and are wrong — which is worse than no number at all.
Calibration ties the page to reality. Once a sheet knows its scale, every measurement you take from it is in real units, and quantities can be exported with confidence.
What you can do
Calibrate scale
Set the sheet scale manually or let the title block be detected automatically.
Measure distances
Linear and polyline measurement in your chosen unit.
Measure areas
Polygon areas and perimeters for floor, roof, and surface quantities.
Measure angles
Verify angles and alignments directly on the drawing.
Count symbols
Tally fixtures and symbols across a sheet or a whole set.
Export quantities
Send organised measurements to a spreadsheet for estimating.
Who it is for
- Estimators producing quantity takeoffs
- Engineers verifying dimensions on issued drawings
- Contractors checking scope before bidding
- Architects coordinating areas across sheets
