How accurate is AI floor plan measurement?

AI measurement is directional and relies on printed dimensions or scale on the plan. It's great for quick quoting and budgeting but is not CAD-grade. SiteScope offers a 5% accuracy refund policy — if our estimate is off by more than 5%, we refund the credit.

Can I use this to estimate paint, tile or drywall coverage?

Yes. SiteScope returns wall area, floor area, ceiling area and perimeters separately, so you can use the right surface for each trade — wall area for painters, floor area for tilers, ceiling area for plasterers.

Is there a free version?

Yes — your first plan is on us. Enter your email on the homepage and we'll add one free credit to your account so you can measure your first plan before paying anything.

Does SiteScope work outside Australia?

Yes. SiteScope works globally with any English-language construction plan. Prices are shown in Australian dollars by default; equivalents in USD, GBP, EUR and other currencies are calculated at checkout.

Frequently asked

About floor area.

How do I calculate floor area from a construction plan?+

Upload your plan to SiteScope. Our AI identifies all enclosed rooms, reads the printed scale or room dimensions, and sums the floor area in square metres (m²). You can convert the result to square feet (ft²) using 1 m² ≈ 10.764 ft².

Does it work with scanned hand-drawn plans?+

Yes, provided the scan is reasonably legible and includes either a printed scale (e.g. 1:100) or labelled room dimensions. Photos of paper plans work too.

What's the accuracy?+

Directional — typically within 3–8% on a well-annotated plan. If the AI estimate is off by more than 5% versus an on-site measurement, we refund the credit.
