Guides · Floor Plan Measurement
The upload step seems simple, but getting it right determines how accurate your final measurement will be. This guide covers every format that works, what to do when your plan has problems, and how to prepare any floor plan for the best result.
MeasureFloorPlan.com accepts JPG, PNG, HEIC, and PDF. PDFs render the first page at high resolution — ideal for exports from CubiCasa, Matterport, iGUIDE, Apex Sketch, and architect drawing packages. HEIC from iPhones works natively. Android JPGs work directly. Scans typically produce JPG or PDF from most office scanners, both of which work well.
Resolution: Higher is always better. A CubiCasa PDF renders sharper than a screenshot of the same plan. You should be able to zoom in and click precisely on a corner without guessing where the wall ends. To scale: The plan must be drawn to scale. CubiCasa, Matterport, iGUIDE, architect drawings, and professional appraisal sketches all qualify. Freehand sketches without labeled dimensions usually don't. Not distorted: If you photographed a printed plan, the camera angle can introduce perspective distortion. An overhead, flat shot minimizes this — see our photo measurement guide.
Blurry scan: Re-scan at 200 DPI or higher. Phone cameras often outperform budget scanners — try photographing the plan in good natural light with your phone held directly overhead. PDF won't upload: Open the PDF in your browser or Preview and print to PDF — this re-renders it to a clean, standard format. Non-scale sketch: If the sketch has at least one labeled room dimension, use that as your scale reference. If there are no labeled dimensions at all, you'll need a reference from another source such as permit records or MLS data. Floor plan tiny on large page: Crop the image so the floor plan fills most of the frame before uploading. This makes tracing much easier.
For CubiCasa, Matterport, or iGUIDE: download as a PDF directly from the platform, not a screenshot. For printed appraisal sketches: scan at 200–300 DPI using document mode rather than photo mode for cleaner line art. For architect drawings: extract just the floor plan sheet from a larger drawing set rather than uploading the full multi-page set. For multi-page PDFs where the floor plan is not on page 1: use your PDF reader to print a single page to a new PDF.
The image appears in the measurement canvas. You trace the perimeter, set scale from one known wall length, and square footage calculates instantly. You can measure multiple areas in a single session — each becomes a labeled polygon with its own area display. The tool shows individual and total square footage as you add polygons.
