Baluster spacing
The spacing between balusters is set for safety: the clear gap must be no more than 10–12 cm.
01 /Safe spacing norms
The baluster spacing (the distance between axes or elements) is calculated primarily for safety, to rule out the risk of a person or pet falling through.
- 👦 Child safety (the main rule). Per GOST and SNiP, the clear gap between balusters must not exceed 10–12 cm. This prevents a child's head from getting stuck.
- 🪵 Wooden balusters (40–50 mm). Installed at 12–15 cm between axes. Usually 2 balusters per step.
- ⚙️ Thin metal posts (12–20 mm). Placed 2–3 per step so the gap between them stays within 10 cm.
- 🧱 Massive concrete or stone balustrades. Because the elements are wide, they are set at 20–25 cm between axes, keeping the clear gap within 12 cm.
