How do I calculate floor area from a construction plan?

Upload your construction plan (PDF, JPG or PNG) to SiteScope. Our AI detects walls, reads the printed dimensions or scale, and returns the total floor area in square metres along with wall area, ceiling area and openings — usually in under 60 seconds.

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.
