How accurate floor plan dimensions are?

Short answer

We can’t guarantee any particular accuracy, but usually it is within 98% of the measured distance.

More details

Floor plans are extracted from 3D scans, which are generated from millions of 3D measurements using our advanced software. But inaccuracies are still present. Depth cameras accuracy degrade with distance. When multiple scans are aligned, errors accumulate as the captured space grows. Thus we can’t guarantee any metrical accuracy, e.g. number of mm, cm or inches, and accuracy depends on the measured distance.

Usual 98% accuracy is good enough for room dimensions and square footage estimation in floor plans. It might not be good enough for architectural applications like estimating size of windows for precise installation.
