Start with the job
Choose Room, Door or opening, Furniture or object, or Custom. Name the project “Living room study.”
A measuring app for Apple Vision Pro
Measure
reality.
Aim at one edge. Select it. Aim at the other edge and select again. Spatial Size shows the distance, lets you name what you measured, and saves it with the project so you can find it again.

One wall, start to finish
A number alone
isn’t enough.
“12′ 8 ⅜″” becomes useful when it says “North wall width,” appears on the wall you measured, records whether you used Laser or Muse, and carries the result of a second check. Here is how it gets there.
Place two points
Aim the red Laser target at the left edge of the wall and select. Aim at the right edge and select again.
Say what it is
Save “North wall width — 12′ 8 ⅜″.” The name, value, source, and measurement line stay together.
Measure it again
Use Check Measure on the same endpoints. See the original, the repeat, and the exact difference before relying on it.

Come back tomorrow
Find the wall,
not just the number.
Open “Living room study” and select “North wall width” in the Project Record. Spatial Size reveals that measurement in the room and spotlights the line you saved.
- 01 Open the project and see every saved record
- 02 Select a record to reveal it in the room
- 03 Use Room Clarity to hide clutter without deleting work
Take the room with you
Export the space—with the measurements on it.
Start an optional Scan Room session and Spatial Size builds a 3D model of the space. Your named measurement lines, values, and drawings appear with the room, so someone opening the model can see what was measured and where.

The 3D export is a scaled presentation model for visual handoff. Saved values remain authoritative in the PDF and CSV.✓

03 LIVING ROOM STUDY · CUTAWAY VIEW
Two ways to place a point
Fast across a room.
Deliberate up close.
Laser is built into the app and ready for room-scale work. If a Logitech Muse is connected, put its tracked tip directly on the point you want. Spatial Size records which method made each result.
Aim, select, move, select.
Use the red target to pick two visible points across a wall, room, object, or opening.
Put the tip on the point.
For deliberate placement, touch the optional Muse tip to each point and press its button.
See whether you can repeat it.
Original 12′ 8 ⅜″. Repeat 12′ 8 ½″. Difference ⅛″. Both captures stay in the record.
MEASURE TWICE. CUT ONCE. Check Measure tells you how closely you repeated the same endpoints. It does not calibrate the headset or replace a final tape check. Confirm critical dimensions before ordering, fabrication, cutting, or another irreversible step.
What happens next
Leave with more
than a screenshot.
What can I measure?−
Measure the distance between two points, outline an irregular area, check level or plumb, or draw directly in the room. Use it for rooms, openings, furniture, artwork, and other physical objects.
Do I need a Logitech Muse?+
No. Laser capture is always available. An optional Logitech Muse adds direct tip-based Precision capture and drawing.
Does it replace a tape measure?+
No. Spatial Size is planning-grade and designed to improve capture, context, repeat checks, and project records. Confirm critical dimensions with a tape before an irreversible step.
Do I need to scan the room first?+
No. A LiDAR scan is optional. It adds a 3D room model and spatial context; Laser and Muse measurements, PDF field reports, and CSV measurement tables remain useful without one.
What can I export?+
Create Export Files gives you a PDF field report with named measurements and checks, a CSV measurement table, machine-readable project data, and—if you scanned the room—a scaled 3D presentation model.
When will it be available?+
Spatial Size is actively in development for Apple Vision Pro. Launch details will be shared when the app is ready for real-world use.
