Stair Railing Height and Baluster Spacing: A Renovator's Guide

t322-5

Stair railing height is measured from the top of the tread or landing surface to the top of the handrail, and baluster spacing is the clear gap between vertical infill bars. Both are governed by Israeli building requirements, including the railing standard SI 1142, so exact values should always be confirmed with your engineer before you order.

What Stair Railing Height Means

Railing height is the vertical distance from the nosing of each stair tread, or from the finished floor at landings, up to the top of the handrail. It is one of the first dimensions a building reviewer checks, because it directly affects how safely someone can hold on while going up or down.

Measure at the front edge of the steps rather than the wall side, since the slope of the stairs changes the apparent height. Keep in mind that the finished floor, tiles and any screed you add later will change the final result.

Understanding Baluster Spacing

Baluster spacing, sometimes called infill spacing, is the clear gap between vertical bars. Its main purpose is safety: openings must be narrow enough that a small child cannot pass through or get a head caught in them.

Measure the clear gap, not center to center.
Check spacing across the full run, including the bottom section near the stair edge.
Confirm the figure against the current standard and your engineer's drawing.

Key Requirements in the Israeli Standard

Most stair railings in Israel are designed with reference to the railing standard SI 1142, which sets out requirements for strength, height and openings. Local planning and building rules can add conditions depending on the building type and use, such as residential, public or commercial.

We do not recommend working from memory or from older projects. Ask for the applicable requirements for your specific property, and make sure your engineer confirms the final dimensions in writing.

How We Measure On Site

Before production, our team visits the property to measure the stair run, landing positions, wall anchor points and the exact geometry of the steps. We record the rise, the tread depth and any irregularities that could affect the railing line.

Photos and a short sketch with dimensions help us plan the installation. We then prepare a written specification for your approval, so every height and spacing figure is agreed before anything goes into the workshop at our Tel Aviv factory on Rival Street 37.

Materials and Finishes That Affect Dimensions

The material you choose can change how the railing is built, though not the safety principles behind it. Steel, stainless steel and aluminum each have different profile sizes and load behavior, which influences post spacing and infill design.

Finishes such as hot-dip galvanizing or powder coating add a thin layer to the surface, so we account for coating thickness when fitting components. Tell us early which finish you prefer so the measurements are planned correctly.

Planning Your Order Step by Step

Confirm the applicable height and spacing requirements with your engineer.
Send photos of the stairs, landings and wall conditions.
Arrange an on-site measurement visit.
Review the drawing and written specification carefully.
Approve the final design before production begins.

Following these steps keeps the project on track and reduces the chance of rework during installation.

Frequently asked questions

Is stair railing height the same for every staircase?

Not necessarily. Requirements can differ based on the building type, the use of the space and the local rules that apply, so each project should be checked individually.

How do I measure baluster spacing correctly?

Measure the clear opening between two adjacent bars at their narrowest point. Check the full length of the stair, including the lower section, and compare the result with the requirement your engineer specifies.

Do I need an engineer to approve my railing?

In most cases, yes. An engineer can confirm that the height, spacing, fixings and loads meet the applicable standard and your building requirements.

Can the railing be adjusted after installation?

Some adjustments are possible, but changing height or spacing after installation is usually costly and time consuming. Confirming dimensions before production is the best way to avoid this.

Common mistakes to avoid

Measuring only from the nosing without considering later floor finishes, and assuming the same spacing works on every section of the stair. Always verify the final figures before ordering.

Our recommendation

Before you order, get the height and spacing requirements confirmed by your engineer and send us site photos so we can check the measurements together. Approving a written specification first saves time and cost.

Summary

Stair railing height and baluster spacing are safety dimensions that must be checked against the applicable standard and confirmed by your engineer before production.
