Should You Install Railings on Both Sides of the Staircase?

t324-41

In most homes, yes: railings on both sides of a staircase give better balance and a handhold whichever side you are on, especially when going up or down with children, shopping, or reduced mobility. A single rail can be enough for a short, straight, low-traffic staircase, so the right answer depends on how the stairs are used.

Why two sides usually make sense

Most people instinctively grab the nearest rail, and on a staircase that can mean switching hands or leaning across a gap. Railings on both sides let every person use the side that feels natural for their body and their load. This matters most on wider stairs, where a single rail is too far to reach comfortably from the opposite edge.

Two rails also support a more even grip. If you carry a laundry basket on one arm, the free hand can still hold firmly on the rail next to you.

When one side may be enough

A single rail can work well when the staircase is narrow, short, and used by one or two adults. If one wall is solid and the other side is open to a drop, a rail on the open side is often the most important one to install first.

Households that benefit most

Families with young children, older residents, and anyone recovering from surgery or an injury are the people who gain most from double-sided support. Children often need a rail at a lower height, and guests may not know where the step edges are. Handrails on both sides give a steady point of contact at every step.

Planning the installation

Before ordering, measure the stair width, the height of each landing, and the wall construction at the mounting points. Decide whether the rail will run continuously along the flight and wrap around the landing ends. Check the height and gap requirements with your engineer, since the Israeli railing standard SI 1142 sets the framework and exact values should be confirmed for your project.

A written drawing lets you confirm the rail position, bracket spacing, and finish before production begins.

Choosing the right design and finish

Metal handrails can be built in steel or aluminum, with a smooth grip profile that is comfortable to hold. Stair areas often see moisture and daily wear, so a protective finish such as hot-dip galvanizing or powder coating helps the rail last. Consider whether glass infill, horizontal bars, or a simple round handrail suits the look of your home.

Next steps for your staircase

Start by walking the staircase as each person in your home would use it, noting where hands reach for support. Take photos of both sides and the landings, then share them with a manufacturer for an on-site measurement. This simple process shows whether one rail or two will best solve your needs.

Frequently asked questions

Do I need railings on both sides of the stairs by law?

Requirements depend on the building type and the specific design, so confirm the applicable requirements with your engineer or building committee. Installing on both sides is a common safety choice even where one side is the minimum.

Is one rail better on the wall side or the open side?

The open side, where a fall would be more serious, is usually the priority. If you can only do one side, that is typically the one to choose.

Can a handrail be added to existing stairs?

In many cases yes, provided the wall or stair structure can hold secure brackets. A site measurement will confirm the mounting method for your staircase.

Will two rails make the stairway look crowded?

Not necessarily. Slim profiles and matching finishes keep the staircase clean and open, and the design can be chosen to suit the style of your home.

Common mistakes to avoid

Choosing a rail height or grip that suits only one user, or ignoring the open side of the staircase. Measure first and check the design against all users.

Our recommendation

Install rails on both sides wherever the stair is wide or used by children, older adults, or guests, and always treat the open side as the top priority. Confirm exact heights and spacing with your engineer before production.

Summary

Railings on both sides of a staircase are usually the safer, more comfortable choice, though a single rail can suffice for a short, low-traffic flight. Assess who uses the stairs and where the drop is before deciding.
