I built Plan Measure, a small open-source browser tool for measuring architectural PDF plans.
The workflow is simple:
- load a PDF
- calibrate the scale using a known distance
- measure straight-line distances
- measure polygon perimeter and area
- export measurements to CSV
It also supports multi-page PDFs, local session recovery, zoom/pan, and editable measurement vertices.
Everything runs locally in the browser. There is no backend, no account, and PDFs are never uploaded anywhere.
Live app:

Source code:

Tech stack:
React, TypeScript, Vite, PDF.js, Konva, IndexedDB.
This is the first stable version, and I’m looking for feedback rather than trying to add features randomly.
If you work with architectural plans, estimating, construction, or takeoffs, I’d especially like to know:
- Was the calibration workflow clear?
- Was anything confusing?
- What important capability is missing?
- Would you use a lightweight tool like this again?
Critical feedback is welcome.
