Why Choose MeasureFloorPlan.com as Your Blueprint Reading Software?

Wall lengths, room areas, perimeter, and square footage from any blueprint, using the same exterior-perimeter method appraisers use in the field.

One wall sets the scale

You only need one known measurement. Trace that wall, enter its length, and every other dimension is calculated from that single input.

Accurate within 1-2%

For a to-scale floor plan from CubiCasa, Matterport, or iGUIDE, expect results within 1-2% of a field measurement.

Works with any floor plan file

JPG, PNG, HEIC, or PDF. Builder plans, MLS screenshots, architect drawings, or a phone photo of a paper sketch.

Built for GLA

Trace the exterior perimeter of finished above-grade space, the same method licensed appraisers use for gross living area.

Free first measurement

Your first on-screen square footage and perimeter are free. No signup required, no software to install.

Saved projects that keep

Every measurement on the monthly plan includes a saved project you can re-open and re-measure free, for as long as you subscribe.

No software to install. Everything runs in your browser.

How Our Blueprint Reader Works

Turn any blueprint into accurate wall lengths, room areas, and square footage in three steps.

1

Upload your blueprint

Drop your blueprint into the tool or click to browse. Any JPG, PNG, HEIC, or PDF screenshot works.

2

Set the scale

Click both ends of one wall you know and enter its length. That single reference calibrates the whole plan.

3

Measure anything

The measuring workspace opens with the distance tool ready. Click two points for a wall length, trace a room for its area, or auto-detect the outline for total square footage. Every result collects in one list.

Works with floor plans from CubiCasa, Matterport, iGUIDE, Apex Sketch, architect drawings, or any photo of a to-scale sketch.

Most measurements take about five minutes

No Plan Measurements? No Problem.

You do not need a single number on the drawing. If the plan has one labeled wall, that sets the scale. If it has none, mark something with a standard size and the tool works out the rest.

Mark a doorway

Interior doors are about 36 inches wide in most homes. Click both sides of any door on the plan and the scale is set.

Use a bathtub or counter

A standard tub is 60 inches long and kitchen counters are 24 inches deep. Pick the object from a list and the tool fills in the size.

Or anything you know

A queen bed, a room you already measured, a garage door. Type in the real size of any one thing and every other measurement follows.

Object-based scale is approximate, usually within 5 to 10 percent. Plenty for renovation estimates, listing square footage, and quick takeoffs. When you need tighter numbers, use any dimension printed on the plan.

Works with unlabeled MLS plans, sketches, and phone photos

Perfect for Every Use Case

From appraisal GLA verification to renovation planning, one tool for every floor plan.

Real estate appraisers

Verify or recalculate GLA from scanned sketches or digital floor plans without re-drawing in sketch software.

Real estate agents

Check listing square footage before it goes live. Catch errors before the appraisal does.

Property managers

Calculate usable area from as-built drawings for lease pricing and tenant planning.

Investors

Independently verify the square footage on acquisition targets without hiring an appraiser.

Landscapers & hardscapers

Measure patios, driveways, and yard areas from a site plan or survey to quote pavers, turf, and materials.

Painting contractors

Estimate jobs from the floor plan before the site visit. Get room areas and wall lengths for accurate quotes.

Flooring & coating contractors

Take off floor area from plans to quote flooring, epoxy, and coatings without driving to the property.

Scaffolding companies

Pull building perimeter and wall lengths from a plan to lay out scaffold runs and quote by linear foot.

Works with any to-scale floor plan: builder plans, MLS listings, CubiCasa or Matterport exports, or a phone photo of a paper sketch.

Frequently Asked Questions

Find answers to common questions about our floor plan measurement tool.

Is there a blueprint reading app I need to download?

No. MeasureFloorPlan is a blueprint reading app that runs in your browser, so there is nothing to install, license, or update. Open the site on a desktop or laptop, upload the blueprint, and start reading dimensions off it. It is built for a mouse or trackpad; on a phone, upload the blueprint and send yourself a link to finish on a desktop.

Does the software read blueprint dimensions automatically?

It reads them from a reference you set, not by guessing. Software to read blueprints automatically usually pulls the scale from a printed dimension or the title block, which breaks the moment a PDF was printed fit-to-page or the blueprint is a phone photo. Here you click both ends of one dimension you trust, and every other wall length, room area, and square footage figure is read from the drawing at that scale. Scanned, hand-drawn, and photographed blueprints all work.

Can I read blueprints online for free?

Yes. Your first blueprint is free, exports included: every number is shown on screen at no cost, with no account, and you can download the labeled PDF and CSV for that plan. After the first one, further blueprints are paid per plan or covered by a monthly plan.

Do I need to know how to read blueprints to use it?

Only enough to find one dimension you trust. If the blueprint is labeled, any wall length works. If it is not, a standard interior door (about 36 inches) or a bathtub (60 inches) is enough to set the scale. From there the blueprint reader does the arithmetic: click two points for a length, trace a room for its area, or outline a floor for its square footage.

How do I measure a floor plan online?

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.

What file types can I upload?

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.

Who is this tool for?

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.

Does it work on mobile?

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.

How accurate is the measurement?

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.

Do I need to know the dimensions of every wall?

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.

What if my floor plan is not to scale?

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.

Can I use the measurement for an appraisal?

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.

Can I measure a multi-story home?

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.

Can I use this for real estate appraisal?

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.

How much does it cost?

Your first measurement is free, exports included: every on-screen number is visible at no cost, no account required, and that plan's labeled PDF, takeoff PDF, and CSV are free to download. After that a plan is $9 (measure it and export it in every format), the $15 monthly Starter plan covers 5 plans a month with saved projects, and the $29 monthly Pro plan covers unlimited plans with saved projects and per-room quantities. Teams of up to 3 can share one $49 monthly bill. Subscriptions cancel anytime.

Can I save or export my measurements?

Yes. Your free first plan includes its exports: download the labeled PDF (traced plan, all wall dimensions, scale reference), the takeoff PDF, and the CSV at no cost. Further plans are $9 each or covered by a monthly plan ($15 for 5 plans a month, $29 for unlimited). To save projects across devices and resume later, subscribe to a monthly plan.
