The Take-Off needs a tablet or computer

Counting fittings and measuring runs on a drawing needs a screen at least 1024 px wide. Your screen is narrower, so parts of the toolbar and price book will be cut off.

The main Duct Pricer calculators work fully on phones — open the calculators — or come back on a larger screen. Your take-offs stay saved in this browser.

Set drawing scale

Pick the printed scale if the PDF was exported at true paper size, or (more reliable) calibrate by clicking two points a known distance apart — e.g. a dimension line, a grid line, or a door opening.
