Enter your measured site and room
Supply the site width and depth, the room rectangle, its type and the north rotation. All dimensions use meters; the canvas origin is top-left, X increases rightwards and Y increases downwards.
Read directional overlaps
The native geometric calculation reports directional shares and central-area overlap for the submitted rectangle. It is a one-room placement reference, not a complete building survey.
Keep a reproducible reference
A confirmed signed-in save retains the selected settings and returned report in your account. Reopen it from saved reports to review the same inputs and method; changing the form later does not rewrite an existing report.
How to use this calculator
- Complete the inputs shown for this specific method. Use a saved family profile where relevant; a birth time or city is requested only when needed.
- Review the declared calculation convention and generate the report. Method differences and unavailable results remain visible.
- When signed in, wait for the cloud-save confirmation. Reopen saved reports from your account history to recover their settings.
Frequently asked questions
How is the north angle measured?
The north angle rotates clockwise from the top of the plan canvas. Confirm the orientation against your own measured plan.
Can I use this as a complete home audit?
This form analyses one rectangular room inside a rectangular site. It does not inspect an uploaded floor plan, structural safety or every feature of a building.
Will this report be saved automatically?
When you are signed in, a successful calculation is saved to your account. Wait for the cloud-save confirmation before leaving the page; guest results are not account records.
