Floor Plan Measurement Tool: No Download Required

MeasureFloorPlan runs in your browser. Upload any floor plan (PDF, JPG, PNG, or HEIC), set one known wall length, trace the perimeter, and read accurate square footage. Your first measurement is free, right on the homepage.

Is it actually free?

Your first floor plan is free, with no account needed: upload it on the homepage, set the scale, and measure as much as you want inside that plan. Distances, rooms, full GLA traces, all of it.

A single additional floor plan is $9, or unlimited measurements are $29 a month with the ability to cancel anytime. For one-off jobs (verifying a listing, checking a comp, one renovation quote) the free first measurement is usually all you need.

What the tool does

• Upload any floor plan. PDF, JPG, PNG, and HEIC all supported. No conversion needed. PDFs are rendered automatically on upload.
• Set scale from one known wall. You only need a single known dimension. Click two points on that wall, enter the length, and every measurement you draw shows its true size.
• Trace any shape. Click around the perimeter of each room or area, or draw a quick rectangle for regular rooms. Area is calculated in real time as you place points.
• Measure distances too. Wall lengths, room widths, and any point-to-point distance, not just areas.
• Multiple areas per plan. Trace the main floor, second floor, and garage as separate polygons. Each is measured independently and summed in the total.
• PDF export. Export your result with the traced floor plan image and GLA total as a PDF document: useful for documentation, appraisal review, or contractor bids.
• Saved projects. Save traced floor plans to your account and return to them later.

Who it is for

• Appraisers. Verify GLA from scanned appraisal sketches, CubiCasa exports, or architect drawings. ANSI Z765-consistent workflow.
• Real estate agents. Check listing square footage before it goes live. Catch data entry errors before they become disclosure problems.
• Investors. Measure floor plans across multiple properties quickly without buying expensive desktop software.
• Homebuyers. Verify the listed square footage of a property before making an offer.
• Property managers. Calculate usable area from as-built drawings for leasing or renovation planning.

How accurate is it?

Accuracy depends on two factors: 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 variance.
