Measure PDF drawings online, free and private
Architectural plans, site drawings and technical sheets are shared as PDF, but reading a length off them usually means printing or opening heavy CAD software. This PDF measurement tool lets you set a scale and measure lengths, areas, wall surfaces and volumes straight in the browser - your drawing is never uploaded anywhere.
Nothing leaves your device
The PDF is opened locally, rendered locally and measured locally. There is no server-side processing, so confidential drawings stay confidential. Your measurements are stored in your own browser and can be exported as a JSON file you keep yourself.
Scale you can trust
The tool reads the page text looking for a ratio such as 1:100 and combines it with the real paper size of the page. Prefer to check it yourself? Calibrate on a printed dimension line, or type the ratio in plain terms: 1 cm on the page equals 1 m in reality.
How to measure a PDF
- Open your PDF drawing - it stays on your own device.
- Check the scale at the top. Adjust it, or calibrate on a dimension you know.
- Pick a tool and click your points. Hold Shift to lock to straight and 45 degree lines.
- Add a height for wall surfaces or volumes, then export your results as CSV, JSON or a marked-up PDF.
