Measure a Room with iPhone LiDAR
Walk the room with a Pro iPhone and get floor area, wall area and the materials to buy.
Measuring a room for paint or flooring means a tape, a helper, a sketch and the nagging feeling you forgot the closet. On an iPhone or iPad Pro, Blueprint uses Apple's RoomPlan and the LiDAR sensor to capture the walls, doors and windows as you walk the room. It works out floor area, perimeter and wall area net of openings, and carries those numbers into the material calculators.

Why it matters
Walls, doors and windows in one pass
RoomPlan maps the room in 3D as you move. Blueprint saves floor area, perimeter, ceiling height and wall area with door and window openings subtracted.
Straight into the calculators
Open the paint, flooring, tile, carpet, crown molding or drywall calculator from a measured room and the dimensions are already filled in.
Appliances spotted on the way
A scan that sees a refrigerator, range, oven, dishwasher, washer or dryer offers to add it as an appliance. You confirm each one.
No LiDAR? Type it in
On an iPhone without LiDAR, or on the web, enter length, width, height, doors and windows and get the same calculations.
How it works
- 01
Scan the room
Open the room in the iPhone app and walk its edges while RoomPlan captures it. Without a LiDAR sensor, type the dimensions instead.
- 02
Check the numbers
Blueprint shows floor area, perimeter, wall area and openings for the room, saved on your home.
- 03
Open a calculator
Pick paint, flooring, tile or drywall and get a materials estimate sized to that room.

Room measuring FAQ
Can I measure a room with my iPhone?
Yes. With Blueprint on an iPhone Pro or iPad Pro, the LiDAR sensor and Apple's RoomPlan capture the room as you walk it. On other iPhones and on the web you enter the dimensions by hand and get the same calculations.
Which iPhones have LiDAR?
The Pro and Pro Max models from iPhone 12 Pro onward, and iPad Pro models from 2020 onward. Blueprint checks whether your device supports RoomPlan and offers manual entry if it does not.
How accurate is a LiDAR room scan?
Good enough for buying paint, flooring and drywall, which is what it is for. For cabinets or countertops cut to fit, measure with a tape.
Which calculators does it fill?
Paint, flooring, tile, carpet, crown molding and drywall. Open one from a measured room and the dimensions come with you.
Does it work on Android?
No. Blueprint's mobile app is iOS only, and the LiDAR scan uses Apple's RoomPlan.
