Stair Railing Height Requirements: A Pre-Order Guide

t329-5

Stair railing height requirements in Israel are set by the building code and the railing standard SI 1142, and they generally call for a guard that is high enough to prevent falls from the open side of the stair. Spacing between balusters must also be tight enough that a small child cannot pass through or get stuck. Always confirm exact dimensions with your engineer or architect before ordering.

Why railing height and spacing matter

A stair railing has two jobs. It gives people something solid to hold while they climb or descend, and it acts as a barrier against falls from the open side of the stairs. Both jobs depend on height and spacing. A railing that is too low can let an adult lose balance and go over it, while wide gaps between balusters can allow a child's head or body to pass through.

Because of this, height and spacing are among the first things a building inspector or engineer checks when reviewing a stair.

The governing standards

In Israel, the main reference for handrails and guards is the standard SI 1142, together with the requirements of the national building regulations. These documents set the framework for what is considered a safe railing. The exact numbers depend on the type of building and the location of the stair, so they should be read in their current form rather than taken from memory or from another country.

Your engineer will know which requirements apply to your project.

Checking the height

Railing height is usually measured vertically from the stair nosing, the front edge of each tread, up to the top of the handrail. For stairs with a guard, the measurement is taken from the floor level at the edge of the open side to the top of the guard.

Measure from the nosing or landing, not from the wall.
Check whether your landing or balcony has its own height rule.
Confirm the height applies on both sides if the stair is open on both.

Baluster spacing and child safety

Vertical balusters should be spaced so that a small object or child cannot pass through the gap. This is one of the most common points raised during inspection, especially in homes with young children. Horizontal bars are generally discouraged on stairs because they can act like a ladder for climbing.

When planning the layout, consider the final gap after the balusters are fitted, not only the design drawing, so that the measured spacing matches what the standard requires.

Handrail design and grip

A handrail should be comfortable to grip and continuous along the full length of the stair. Its profile and diameter affect how easily a person can hold it, and rounded shapes are generally easier to grasp than sharp edges. The handrail should also extend past the top and bottom steps so that users can hold it before they begin and after they finish.

Handrail mounting must be strong enough to take a person's full weight if they grab it while slipping.

Preparing your order

To avoid delays, prepare the key information before you order: the number of steps, the total rise, which sides are open, whether there is a wall on one side, and whether the stair is inside or outside. Photos of the stair and a rough sketch help a lot.

Our team measures on site, produces to your exact dimensions in our Tel Aviv factory, and provides a written specification for approval before production begins. Share your engineer's requirements at this stage so the drawing matches the approved design.

Frequently asked questions

Is there one fixed railing height for every stair?

Not always. Requirements can differ by building type, location and whether the stair is open on one or both sides. Check the current standard and confirm with your engineer.

How do I know if the baluster spacing is safe?

The gaps should be narrow enough that a small child cannot pass through or become trapped. Your engineer or inspector can confirm the required spacing for your project.

Do I need a handrail as well as a guard?

Often yes. A handrail is for grip and support, while a guard is for fall protection. Many stairs need both, and your plan should show which ones apply.

Can I measure the railing height myself?

You can take rough measurements to plan, but final dimensions should be checked on site by a professional before production, since small differences matter.

Common mistakes to avoid

Many homeowners measure from the wall instead of the nosing, or order before confirming the spacing requirement. Both errors can lead to a railing that must be redone.

Our recommendation

Before ordering, send your engineer's requirements together with photos and approximate step count so we can produce to your approved drawing. Ask for the written specification to be signed off before production starts.

Summary

Stair railing height and spacing must follow the current Israeli standard and your engineer's requirements, so confirm them before you order. Accurate measurement and a written approved specification prevent costly changes later.
