Works with floor plans from CubiCasa · Matterport · iGUIDE · architect drawings · MLS screenshots · PDFs
Upload a JPG, PNG, or PDF of any floor plan, set the scale with one known wall, and measure anything: wall lengths, room areas, perimeter, and total square footage. Works with CubiCasa, Matterport, iGUIDE, architect drawings, and MLS screenshots.
Upload your floor plan ↑Wall lengths, room areas, perimeter, and square footage from any floor plan, using the same exterior-perimeter method appraisers use in the field.
Turn any floor plan image into accurate wall lengths, room areas, and square footage in three steps.
Works with floor plans from CubiCasa, Matterport, iGUIDE, Apex Sketch, architect drawings, or any photo of a to-scale sketch.
Gross Living Area (GLA) is the standard measure of residential square footage used by licensed appraisers. It counts only finished, above-grade, heated and cooled space: measured from exterior walls.
GLA is what determines comparable sales adjustments, listing accuracy, and lender value. Finished basements, garages, and unheated porches are measured separately and do not count toward GLA regardless of how finished they are.

Upload your floor plan image, set the scale by clicking both ends of a known wall length, and start measuring: click two points for a distance, trace a room for its area, or auto-detect the outline for total square footage. Lengths appear on the plan as you draw, and you can add multiple areas for multi-story homes.
JPG, PNG, HEIC, or any image export of a PDF floor plan. As long as the floor plan is visible as an image, you can upload and trace it. PDFs are automatically rendered to an image on upload.
Real estate appraisers verifying GLA from scanned sketches, agents checking listing square footage before it goes live, property managers calculating usable area from as-built drawings, and homeowners measuring rooms for renovation planning. Trades use it too: landscapers, painters, flooring and coating contractors, and scaffolding companies quoting jobs from site plans and floor plans.
The tool is optimized for desktop and laptop use. Precise point placement works best with a mouse or trackpad. It will load on a tablet but touch-based tracing on small screens is less accurate. Best results on a desktop browser.
Accuracy depends on two things: the quality of your floor plan and how precisely you set the scale. For a professional to-scale floor plan from CubiCasa, Matterport, or iGUIDE, you can expect results within 1-2% of a field measurement. Hand-drawn or rough sketches will have more error.
No. You only need one known measurement. Any wall where you know the real-world length. Set that as your scale reference and the tool calculates all other dimensions from that single input.
The tool measures what is in the image. If the floor plan is not drawn to a consistent scale. For example a rough hand sketch where proportions are eyeballed. The result will reflect those proportions, not the actual structure. For best results, use a to-scale floor plan from a scanner, professional software, or an architect drawing.
The tool measures gross living area (GLA) by tracing the exterior perimeter of finished above-grade space, the same method used in residential appraisal. You control which areas to include, so below-grade space can be measured separately.
Yes. You can add multiple separate polygon areas. One for each floor. Each polygon is measured independently and all areas are summed in the total. Measure the main floor, upper floor, and garage separately to keep above-grade and below-grade area organized.
Yes. The tool is built specifically for real estate appraisers who need to verify or recalculate GLA from floor plan sketches or scans. It is faster than manually re-sketching and provides a reliable second check. The appraiser is responsible for confirming the input floor plan is accurate and to scale.
Your first measurement is free. The on-screen square footage and perimeter are visible without an account. A labeled PDF download (with the traced plan, every wall length, and scale calibration) is $7 per property. If you have multiple properties, $15 gets you 5 measurement credits and $25 gets you 10. Credits never expire, and every measurement includes a saved project you can re-open and re-measure free.
The on-screen square footage is free to read or screenshot. To download a clean labeled PDF (traced plan, all wall dimensions, scale reference), buy the $7 PDF. To save projects across devices and resume later, get a credit pack.
Upload a plan, trace the perimeter, and get accurate square footage in about five minutes. Your first measurement is free, no signup required.
