The small end
The smallest thing worth scanning meaningfully is about fingertip-sized — a piece of jewellery, a dental model, a small mechanism part. Smaller is possible too, but at that point it's worth asking whether scanning is even the right tool, or whether it's simpler to draw the thing by hand.
The large end
The Matterport Pro3 covers a whole flat in a day and there isn't really an upper limit — a bigger building just takes longer. The object scanners (Einscan H2 and SE V2) suit objects from a few centimetres to a couple of metres, depending on how many positions the scan needs.
Which scanner for which size
- Einscan SE V2
- small parts on a turntable, up to about 20 cm
- Einscan H2
- medium and larger objects, handheld, furniture and car-part scale
- Matterport Pro3
- rooms and buildings, practically no upper limit
Where the choice actually shifts
The line isn't sharp, it's a trade-off between accuracy and coverage. A small scanner gives a large object more positions and more time. A large scanner gives a small object less detail. If you're not sure which you need, send a photo with something for scale beside it — I'll tell you honestly which one fits.
Send a photo with a tape measure beside it and I'll tell you which scanner fits.
