Areaplane is now on iPhone and iPad.

Built for power users, and for measuring on the fly, like when you are quoting a job on site. Trace floor plans and satellite maps with a finger, and keep every project in sync through iCloud.

  • Floor plans and satellite maps

    Import a plan photo, or search an address and trace the lot on satellite imagery.

  • Totals and PDF reports

    Group rooms and areas, see a total for each group, and share a report.

  • iCloud sync

    Start a project on iPhone and finish it on iPad.

  • Works with the website

    Open areaplane.com project files in the app, and app projects on the web.

The app is free to try, with project limits until you upgrade to Areaplane Pro. The web version is free, with no limits.

How it works

Upload a plan, set one known distance, trace what you need.

Read the guides
  1. STEP 01

    Upload or search

    Drop in a floor plan, PDF, or site image, or search an address on satellite view.

  2. STEP 02

    Set the scale

    Mark one distance you already know. Every measurement after that is calibrated to it.

  3. STEP 03

    Trace and read

    Outline a room, roof, or lawn. Area and length appear instantly in ft² or m².

Private by design

Your plans never leave your browser.

Floor plans, site images, and measurements are processed on your device and saved in your browser's local storage. Clearing browsing data removes them, so download a project file now and then as a backup.

How your data is handled
  • No account, no uploads

    Open a tool and start measuring. Nothing is sent to a server.

  • Auto-saved locally

    Close the tab and come back later. Export a JSON project to move between devices.

  • Map imagery only when you search

    The satellite tool fetches tiles from Esri and OpenStreetMap. Your outlines stay local.

FAQ

Area calculator questions

Formulas, unit conversions, and what to expect from an online measurement.

How do I calculate square footage?

Multiply the length of a space by its width. For example, a 12 ft x 15 ft room is 180 sq ft. For irregular shapes, divide the area into rectangles and triangles, calculate each one separately, and add them together. Areaplane automates this. Upload a floor plan or draw on a map and the area is calculated instantly.

What is the difference between square feet and square meters?

Square feet (sq ft) and square meters (sq m) are both units of area. 1 square meter equals approximately 10.764 square feet. To convert sq ft to sq m, divide by 10.764. To convert sq m to sq ft, multiply by 10.764.

How accurate are online area calculators?

Accuracy depends on the source image, scale calibration, and how carefully you trace. Satellite imagery also varies by location and capture angle. Check a known dimension before estimating materials; the tool does not establish legal property boundaries or replace a survey.

Can I measure area on Google Maps for free?

Yes. Areaplane provides a free satellite view calculator. Search any address, draw a polygon around the area you want to measure, and the tool calculates the area instantly. No sign-up or software installation required.

What is the formula for square footage?

For a rectangle: Area = Length x Width. For a triangle: Area = (Base x Height) / 2. For a circle: Area = π x Radius². For irregular shapes, break them into simple shapes, calculate each area, and sum them. One square foot equals 144 square inches or 0.0929 square meters.

Can Areaplane help me design an irrigation system?

Yes. Our free Irrigation Planner (beta) lets you upload a floor plan or satellite image of your property, calibrate the scale, and place individual sprinkler heads — rotors, sprays, MP rotators — or draw drip lines for shrub beds. It groups heads into zones, checks each zone against your available GPM, and exports a multi-page PDF with a bill of materials including swing joints, valves, pipe sizing, control wire, and valve boxes. It is intended for educational use and does not replace a licensed irrigation specialist.

What sprinkler heads does the Irrigation Planner support?

The planner includes spray, rotor, MP rotator, and drip categories with catalog-based material estimates. Review each suggested model, nozzle, arc, operating pressure, and flow against current manufacturer specifications before ordering.

Is there an Areaplane app for iPhone or iPad?

Yes. Areaplane is on the App Store for iPhone and iPad. It is built for power users and for measuring on the fly, like quoting a job on site. It measures floor plans and satellite maps, groups measurements with totals, exports PDF reports, and syncs projects through iCloud. The app is free with project limits, and Areaplane Pro unlocks unlimited use with a yearly subscription or a one-time lifetime purchase. The web version at areaplane.com is fully free, with no limits, and project files move between the two.
