Calibrate before you measure
Scale-aware measurement keeps lengths and areas grounded in the drawing instead of disconnected from the review notes.
PDF measurement
Calibrated PDF Measurement Tool
Set drawing scale, measure directly on the PDF, and keep measurements visible alongside the markups and comments that explain the work.

Measure inside the markup workflow
Contractors can measure, annotate, count, and comment without jumping between a viewer, spreadsheet, and screenshot tool.
Export the evidence
Marked-up PDFs preserve the measurement context so others can understand how the number was checked.
Common Questions
Short answers for contractors comparing markup, annotation, measurement, and review tools.
Can I measure a scaled PDF drawing?
Yes. Calibrate the drawing scale first, then use measurement tools to check lengths and areas directly on the PDF.
Is ContractorCounter only for estimating?
ContractorCounter is focused on drawing markup, PDF annotation, calibrated measurement, counts, stamps, comments, and clean exports. Estimating can happen after the markup work is clear.
Does it work in the browser?
Yes. Contractors can open construction drawings, add markups, measure, count, and export without installing desktop-only PDF software.
