What Size Shelving Unit Do You Need for a Landing?

For most UK landings, a shelving unit somewhere between 20 and 30cm deep is the right size, with the width set by the wall you have and the height kept low if the unit sits near a window or the top of the stairs. The key measurement is not the shelving itself but the space left around it: you need a clear walkway past the unit, full clearance at the stairhead, and room for every bedroom and bathroom door to open without catching. Once those are protected, the shelving can fill whatever remains.

In practice, that usually means a slim unit around waist height on a short landing, or a taller, narrow bookcase on a longer landing with a solid stretch of wall. Our range of modern shelving units UK sale lists full dimensions for every design, and this guide explains how to work out which size suits your landing.

Why Landing Measurements Are Different

In a living room, a shelving unit only needs to fit against the wall and leave space for seating. On a landing, it shares a narrow area with the head of the stairs, several doors and the route everyone takes to and from bed. That makes clearance the first priority and storage the second.

Landings also vary more than most rooms. A Victorian terrace may have a long, narrow landing with a window at the end. A modern semi often has a compact, square landing with four doors opening off it. A bungalow conversion may have a landing under a sloping roof. The same unit will not suit all three, which is why measuring your own space carefully matters more than following a standard size. Shelving sizes on landings follow the same broad logic as elsewhere in the home, and our wider living room furniture UK range shows how depth and height change with the room.

Step One: Protect the Stairhead

Stand at the top of the stairs and look at the floor space directly in front of you. This area should stay completely clear so that anyone arriving at the top step can move onto the landing without turning or stepping around anything.

A practical approach is to keep a clear zone at the top of the stairs that is at least as long and wide as the staircase itself. Mark it on the floor with masking tape. Nothing, including the corner of a shelving unit, should sit inside that zone.

Step Two: Measure the Walkway

Next, measure the width of the landing at the point where you are considering the shelving. Then subtract the depth of the unit you have in mind. What remains is your walkway.

The walkway needs to feel comfortable, not just passable. Think about carrying a full laundry basket, helping a child to bed or walking through half asleep at night. If the remaining width feels tight when you walk it with the tape still on the floor, the unit is too deep.

Landing and hallway widths vary considerably by property type, so take your own measurement at more than one point along the landing rather than relying on a single reading.

Step Three: Check Every Door Swing

Open each door that leads off the landing fully and mark the arc it makes on the floor. Many UK landings have doors close together, and a shelving unit placed between two doors can easily block one from opening completely. Airing cupboard doors are often forgotten, as is the loft hatch above, which needs space for a ladder.

Step Four: Choose the Depth

With clearance protected, you can choose a depth based on what you want to store.

• Around 15 to 20cm: suitable for paperbacks, small objects, toiletries and photographs. Useful on very narrow landings.
• Around 20 to 30cm: fits most books, folded towels and baskets. This range suits the majority of landings.
• Over 30cm: best reserved for wide landings or alcoves set back from the walkway, where the depth does not narrow the route.

If you are torn between two depths, choose the shallower one. A few centimetres of extra storage rarely makes up for a walkway that feels cramped every day.

Step Five: Choose the Width

Width is more flexible than depth, because it runs along the wall rather than into the walkway. Measure the uninterrupted stretch of wall available, then subtract a small margin at each end so the unit does not look squeezed between door frames.

On a short wall between two doors, a unit that fills most of the space looks neat and intentional. On a long wall, a unit that takes up around half to two thirds of the length often looks more balanced than one that runs end to end, leaving space for a picture or simply breathing room.

Step Six: Choose the Height

Height depends on three things: the window, the stairs and the ceiling.

Under a Window

A low unit below sill height keeps natural light flowing into the stairwell. It also creates a useful surface for a lamp or plant.

Near the Top of the Stairs

Keep units close to the stairs low, so they do not block sight lines or feel looming as you climb. A low unit also feels less likely to be knocked.

On a Blank Wall

A taller unit can work well on a solid stretch of wall away from the stairhead. It turns the landing into a small library without taking more floor space than a low unit.

Under a Sloping Ceiling

Measure the ceiling height at both the front and back of where the unit will stand. A stepped or low unit can follow the slope neatly.

Common Landing Sizes and What Usually Fits

Every home is different, but some general patterns apply.

• Compact square landings with several doors often suit a single low unit under a window, or wall mounted shelves above head height.
• Long, narrow landings in terraced houses often suit a slim, shallow bookcase on the wall opposite the doors.
• Wide landings in larger homes can take a broader unit, sometimes with a chair beside it to create a reading corner.
• Split level landings may offer a small half landing where a low unit adds interest without blocking the route.

When a Bookcase Works Better

If your main goal is book storage, a narrow bookcase with fixed shelves may suit the landing better than open shelving. Bookcases often have a back panel that keeps books tidy and stops them being pushed through to the wall. Our modern bookcases UK sale include slim designs that fit landings comfortably.

If you need closed storage for linen or children’s things, a shallow cabinet or chest may be more practical. Our hallway storage furniture UK range includes pieces with doors and drawers that work upstairs as well as down.

Testing Before You Choose

Once you have a size in mind, mark the full footprint and height on the wall and floor with masking tape. Leave it in place for a day or two and walk past it as you normally would. This simple test shows whether the unit feels comfortable, whether it catches the light from a window, and whether it interrupts the way you move through the house.

It can help to compare your numbers with typical figures. Our article on average UK hallway sizes by property type gives useful context on how your home compares, and our guide to hallway furniture depth and corridor clearance in UK homes looks more closely at how furniture depth affects movement through narrow spaces.

Remember to measure the route up the stairs as well. Tall units must be carried round the turn of the staircase, and some will need to be assembled on the landing itself.

Fixing and Finishing

Whatever size you choose, fix the unit securely to the wall. Landings are busy, and units near the stairs should never be at risk of tipping. Many upstairs walls are stud partitions, so find the timber studs for a secure fixing.

Choose a light finish if the landing is dim, and keep the styling simple so the space feels open.

Frequently Asked Questions

What depth of shelving unit is best for a landing?

Around 20 to 30cm suits most landings and holds books, towels and baskets. On very narrow landings, a depth of 15 to 20cm or wall mounted shelves may be more comfortable.

How much space should I leave at the top of the stairs?

Keep a clear area at the stairhead that is at least as long and wide as the staircase itself, so anyone arriving can step onto the landing without obstruction.

Can a tall shelving unit go on a landing?

Yes, on a solid stretch of wall away from the top of the stairs, as long as it is shallow and fixed securely to the wall.

How do I test whether a shelving unit will fit my landing?

Mark its footprint and height with masking tape and leave it for a day or two. Walk past it as normal and check that doors open fully and the walkway feels comfortable.
