The Steel HR 36mm looks in proportion on wrists of 13–18.5 cm (5.1–7.3 in) round, and fills the wrist at 13.5–15 cm (lug-to-lug estimated at ≈41.5mm; Withings does not publish it).

Does the Steel HR 36mm fit your wrist?
The 36mm suits wrists of about 13–18.5 cm round; the 40mm, 14–20 cm. Both work from 14 to 18.5 cm, where it is a choice between more skin either side (the 36mm) and a case that fills the wrist (the 40mm). Under 14 cm only the 36mm's lugs stay on the wrist; over 18.5 cm the 36mm starts to look small.
