Measure with your phone camera

No ruler at hand? When the agent asks how big something is (a router, a phone, a pipe), you can measure it with your phone. Put an object of known size next to it, take a photo, and the values appear in the question on your computer.

What you need

One reference object, lying right next to the thing you measure:

A card works best for small things, a sheet for bigger ones. Don't worry about what's printed on the card: the photo stays in your private files.

Step by step

1. When the agent's question has size fields (width, depth, height, diameter…), click Measure with my phone camera.
2. Scan the QR code with your phone's camera. The page opens without signing in; the code works for one phone, once, and expires after 10 minutes.
3. On your phone, choose your reference (or leave Find it for me).
4. From above: hold the phone straight over the object, with the card lying flat next to it. Keep the whole card and the whole object in the picture.
5. From the side (for heights): stand the card up against the object and shoot straight from the front.
6. Tap Measure. Your phone shows the result, drawn on the photo, and says "Done — check your computer".
7. On your computer, click Use these values. The fields fill in, each marked "from photo ±2 mm" (or whatever the range is). Edit anything that looks off, then click Looks right (or Send answer in the editor) to answer as usual.

Already on your phone? The button opens the camera page right there, no QR code needed.

No question open?

Press ⌘K (Ctrl K on Windows) and choose Measure something with my phone. Pick a box (width × depth × height) or a round thing (diameter × height). The measurement goes into your prompt as text, for example: "Measured with my phone camera (next to a bank or ID card): width 120 mm (±3 mm), depth 80 mm (±4 mm), height 45 mm (±2 mm)."

How it works, and how far to trust it

The AI finds the reference's corners (or the coin's edge) and the two ends of each dimension. Solid Vibes then does the math: the known size of the reference gives the scale, the shape of the reference tells how tilted the photo is, and edges that sit higher than the card (the top of a box) are corrected for being closer to the camera. Every value comes with a ± range and is rounded to match it, so you never get false precision like 120.37 mm.

Photo measurements are good for fitting things around an object with a few millimetres of clearance. For tight fits (press fits, snap fits, bearings) check with calipers (see "Tolerances and fit" below).

When it asks for a retake

Solid Vibes would rather ask again than guess. You'll see a specific tip, for example:

• No reference found: put the card flat, right next to the object, fully in the picture.
• Too steep an angle: hold the phone straight above (or straight in front for the side photo).
• Reference cut off: keep the whole card or sheet inside the frame.
• Blurry: hold still, tap the object to focus, add light.
• Which coin? pick your coin on the phone, then measure again.

Heights need the side photo. Without it, a height is shown as a "rough estimate" with a wide range, or left for you to type.

Credits and privacy

A successful measurement costs a few credits (camera_measure, shown on Account → AI credits); a retake request is free. The photos are stored in your workspace's files, checked for viruses like every upload, and only used for this measurement. Nobody who doesn't have the code can open the page, and the page shows nothing but the question.
