Create Room Measurements and Floor Plans With Your Phone

A floor plan used to mean graph paper, a tape measure, and a lot of walking back and forth. With Measure Tools, your phone camera does the walking for you: you point at the corners of the room, the app builds the walls, and a couple of minutes later you are looking at your room as a real plan — flat on paper in the 2D view, or as a walk-around model in 3D. It runs on both iPhone and Android phones, so the same app works for you, your partner, and your contractor.

Floor Plan mode in AR: marked room corners linked across the floor into the room's perimeter outline, with wall lengths shown — Floor Plan mode: tap each corner on the floor and the app links them into the room’s perimeter.

Measure Tools is free to download — you can try Floor Plan mode for free. The complete 2D & 3D viewing capabilities require the premium 3D Planning subscription.

What You Can Create

Floor Plan mode is built around one job: turning the room you are standing in into a plan you can actually use. From a single pass around the room you get:

A saved floor plan opened in the 3D viewer: room walls at their measured heights with window and door panels in place — A saved plan in the 3D viewer — walls at their real heights, openings included.

A room outline with per-wall lengths. Every wall segment in your plan carries its own measured length, so you can read the dimension of any wall straight off the plan instead of measuring it again.
Wall heights. Set the height of your walls either by physically raising the phone to the ceiling or by typing the value in — useful when you already know the ceiling height from the building documents.
Floor area. The plan computes the floor area of the closed outline, which is the number you need for flooring, paint coverage estimates, and rental or listing descriptions.
Windows and doors placed on your walls. Openings you add appear as openings in the 2D plan and as panels in the 3D room view, so the plan reflects where light comes in and where people walk through — the two things that decide most furniture layouts.
Saved floor plan projects with in-app 2D and 3D viewing. With the 3D Planning subscription, each finished plan is stored as a project you can reopen any time — flip between the flat 2D drawing and the 3D room model, at home or in the store aisle.

How It Works

Creating a plan is a three-step flow in AR — no drawing skills required, and no special hardware beyond a reasonably recent phone:

Adding a door to a wall in Floor Plan mode: two taps place the opening, and the door snaps its bottom edge to the floor — Two taps on a wall place a door — it snaps to the floor automatically.

Mark the room corners. Walk the room, aim the on-screen target at each corner on the floor, and tap to mark it. When you mark your starting corner again, the outline closes the perimeter and your walls are set.
Set wall heights. Raise the phone toward the ceiling and the app measures the height for you — or simply type the value if you already know it.
Add windows and doors. Two taps on a wall place an opening: aim at one corner, tap, aim at the opposite corner, tap — and the window or door fills in between them. Doors snap their bottom edge to the floor automatically, so they always sit where a real door would.

When the plan is done, save it as a project and revisit it whenever you need it, in 2D or 3D (saving requires the 3D Planning subscription). You can also share measurement-overlay photos from the app — a camera shot of the room with your measurements drawn on top — which is often the fastest way to send a dimension to someone who just needs the number, not the whole plan.

Best For

Renovation planning. Capture the room as it is before you talk to anyone about how it should be. Wall lengths, heights, and opening positions in one place beat a page of scribbled numbers.
Flooring estimates. The floor area of the closed outline gives you the base number for laminate, tile, or carpet — see our guide on measuring a room for flooring for how to handle waste margins.
Real estate walkthroughs. Walk a property once and leave with a plan of each room instead of a gallery of photos you will struggle to interpret later.
Moving and furniture layout. Knowing your wall lengths and where the doors and windows sit answers the only question that matters on moving day: will it fit, and where?
Contractor discussions. Opening a 3D view of the actual room mid-conversation keeps everyone talking about the same wall — and the per-wall lengths mean fewer “can you go measure that again” calls.

How It Compares to Pro Floor Plan Tools

There are heavier, survey-grade floor plan tools on the market — they go deeper on branded reports, cost estimation, and contractor workflows, and if you produce survey documents for a living they earn their complexity. Measure Tools sits deliberately on the other end: it is faster and simpler for quick room planning. You open the app, tap the corners, and have a usable plan in minutes, inside the same app you already use for everyday AR measuring.

One honest boundary: Measure Tools does not currently offer CAD/DXF file export. Today your plans live inside the app as projects with 2D and 3D viewing, and dimensions travel out as measurement-overlay photos. If your workflow ends in AutoCAD, a dedicated survey tool is the better fit for now; if it ends in a decision — what to buy, what fits, what to tell the contractor — Measure Tools gets you there with far less overhead.

Floor plans are part of the 3D Planning subscription, which also unlocks unrestricted custom real-size furniture — adjustable 3D furniture models you can place and resize inside your room in AR, then walk around the layout in the real room to test it against the plan you just made (our guide to previewing furniture in your room covers the styles and materials side). The Measurements subscription covers the full measuring toolset (including Virtual Wall and Rectangle modes) with unlimited measurement folders; 3D Planning includes everything in Measurements. The bubble level and onscreen ruler work right away, no subscription needed.

Accuracy and Device Notes

An AR floor plan is only as good as the tracking behind it, so it is worth knowing what helps and what hurts:

Tracking quality drives plan quality. AR accuracy depends on lighting, surface texture, and steady tracking. A bright room with a patterned or textured floor tracks well; dim light and bare glossy floors track poorly.
Clear corners matter. Mark corners you can actually see. If a sofa hides a corner, move it or aim carefully at the floor line — a corner marked half a step off skews two walls at once.
LiDAR devices do better. Pro iPhones and iPads with a LiDAR scanner place points on the floor more accurately than camera-only devices. Camera-only phones still produce useful plans; give them an extra moment to lock onto the floor before tapping.
Treat the plan as an estimate for planning. It is ideal for layouts, quotes, shopping decisions, and discussions. For construction-grade decisions — cutting materials, ordering built-ins, anything with tight tolerances — verify the key dimensions with a tape measure before you commit.

Frequently asked questions

How do you make a floor plan with your phone?

Three steps in AR: walk the room and mark each corner on the floor through the camera; set the wall heights (raise the phone to the ceiling, or type the value); then add windows and doors with two taps per opening. The result is a plan with per-wall lengths and floor area you can view in 2D or 3D — no drawing skills involved.

Do floor plan apps need LiDAR?

No. Measure Tools builds floor plans on any modern iPhone or Android phone using camera-based AR. A LiDAR scanner (Pro iPhones and iPads) places corner points faster and more accurately, especially in low light — but camera-only phones produce useful plans in good conditions.

Can I export the floor plan to CAD or PDF?

Not currently — and we would rather tell you before you download. Today plans live inside the app as projects with 2D and 3D viewing, and dimensions travel out as measurement-overlay photos. If your workflow ends in AutoCAD or formal survey reports, a dedicated survey tool is the better fit for now; if it ends in a decision about what fits and what to buy, the in-app plan gets you there faster.

How accurate is a phone floor plan?

Accurate enough for layouts, quotes, shopping and contractor discussions — wall lengths and floor area are AR estimates whose quality depends on lighting, floor texture and careful corner marking. For construction-grade decisions like cutting materials or ordering built-ins, verify the key dimensions with a tape measure.
