In Poland, according to the Polish Building Code (Warunki Techniczne), the minimum height for balcony railings (balustrades) is:
1.1 meters (110 cm) from the finished floor level of the balcony.
Additional Notes:
If the balcony is located above a certain height (e.g., higher floors), this 1.1 m requirement still applies.
The railing must also be designed to prevent falling—meaning no large gaps that could let a child slip through. Typically, openings should not exceed 12 cm.
Materials must be durable, stable, and resistant to weather.
