Railing Height and Load Requirements by Country: One Table for 12 Markets
Safety · · By Prince Railing
Most countries set a railing at 900 to 1,100 mm high and design it for a horizontal line load of roughly 0.35 to 3.0 kN/m depending on how many people can crowd against it. The table below gives the commonly cited figures and governing documents for twelve markets; every one must be confirmed with the project engineer and local authority.
In one line: nearly every building code puts a railing or balustrade between 900 and 1,100 mm high and asks it to resist a horizontal line load of about 0.35 kN/m in a private house up to 3.0 kN/m where crowds gather, plus a concentrated point load and a load on the infill. The numbers differ by country, by occupancy and by the height of the fall, and the glass rules differ even more. This page collects the commonly cited figures in one table so a fabricator, importer or specifier can see at a glance what a destination expects before the engineer does the real design.
Read the table with two cautions. The figures are the minimums most often quoted for each code and are current to the best of our knowledge, but codes are revised, states and emirates amend them, and a project specification can exceed them. Compliance is assessed on the installed barrier, with its glass, fixings and structure, by the engineer or certifier for that project. We manufacture the hardware; we do not certify barriers to any of these codes, and nothing here replaces the engineer's calculation.
The three loads every code asks for
- Line load (kN/m). A uniform horizontal push applied along the top of the barrier, standing in for people leaning on it. This is the figure that drives the size of posts, brackets and base channels and the thickness of a frameless glass panel. It rises with occupancy: a bedroom balcony sees a few people, a stadium concourse sees a crowd.
- Concentrated load (kN). A single point push at the top, standing in for one person falling against it. It governs localised parts such as a handrail span between brackets.
- Infill load (kN/m²). A pressure on the panel face below the top rail, standing in for a person or object pushing on the glass or the balusters. For a glass infill it is checked alongside wind pressure, which on an exposed upper floor can be larger; see our wind load on glass railings guide.
The loads are not combined; the barrier is checked for each case separately. Units are mixed between markets: Americans quote pounds per linear foot (plf) and pounds, Europeans and most of Asia use kN/m and kN. A useful conversion is 50 plf ≈ 0.73 kN/m and 200 lb ≈ 0.89 kN.
Railing height and load by country
Commonly cited minimums. "Residential" means a private dwelling; "public" means offices, retail, hotels and assembly, with the higher figure in a range applying where crowds can gather. Confirm every figure with the engineer and the authority for the project.

What the table has in common
Strip away the units and the document names and the same three ideas appear everywhere.
- Height follows the fall. A low drop inside a house gets 900 mm; a balcony on an upper floor gets 1,000 to 1,100 mm; Germany and Spain write the step into the code explicitly, at 12 m and 6 m of fall respectively. India's 1,000 mm balcony figure sits in the middle of the range, which is why Indian fabricators are rarely surprised by a foreign height but are often surprised by the load.
- Load follows the crowd. The single-dwelling figure is small everywhere (0.35 to 0.8 kN/m) and the crowd figure is large everywhere (2.0 to 3.0 kN/m). A railing system that is comfortable on a villa balcony can be entirely wrong on a stadium concourse at the same height. Our commercial railing requirements guide deals with that end of the range.
- Glass without a rail is a special case. The IBC, BS 6180, AS 1288 and DIN 18008 all reach the same conclusion by different routes: a frameless panel whose top edge is the barrier should be laminated, so that a broken ply leaves a barrier standing, or it should carry a continuous rail that bridges to the next panel. The reasoning is in our toughened vs laminated glass guide.
What this means for the hardware
The destination's height and line load, taken together, fix the bending moment at the base of the barrier, and that is the number the fixing system has to carry. A continuous base channel spreads it along the whole glass edge, which is why it is the usual answer for tall or heavily loaded panels; spigots concentrate it at two points per panel and are specified against the panel size and load; brackets sit between. The glass thickness and make-up follow from the same calculation, and the glass railing thickness guide shows the typical pairings.
When you send an export enquiry, the most useful things to include are the barrier height, the line load your engineer is designing to, the glass thickness, and whether the panel carries a top rail. With those four facts we can confirm which profiles suit that supported height. Everything else about buying from India, from packing to Incoterms, is in our guide to importing railing hardware from India, and the export page lists each market with its own terms, ports and climate advice.
A note on India
For a project in India the figures to work from are NBC 2016 for height and gaps and IS 875 Part 2 for the horizontal loads on balustrades and parapets, with wind from IS 875 Part 3 on exposed upper floors. Indian practice on high-rises has moved above the code minimum, with 1,050 to 1,200 mm now common on tower balconies. The full Indian picture, including the 100 mm gap rule, climbability and a sign-off checklist, is in our railing height and safety standards guide; the glass-specific heights are in the glass railing height guide.
