How to Measure Your Room for a Bedroom Bench in 8 Easy Steps

To measure your room for a bedroom bench, work out the width of your bed, leave at least 60cm of clear walking space beyond the bench, and choose a bench roughly two thirds to three quarters of the bed width. In practice that means a bench of about 100cm to 120cm for a double bed and 120cm to 140cm for a king. If the gap between the foot of your bed and the opposite wall or wardrobe is under 90cm, a bench will make the room difficult to move through.

The eight steps below take about fifteen minutes with a tape measure and a pencil. Do them properly and you avoid the two common outcomes: a bench that blocks the route to the wardrobe, or one so small it looks stranded at the end of the bed.

Step 1: Measure the full length of the room

Start with the wall that runs parallel to the side of your bed. Measure from skirting to skirting rather than corner to corner, because skirting boards can take two or three centimetres off the usable floor. Write the number down rather than trying to hold several figures in your head.

If the room is not a true rectangle, and many British bedrooms are not, take the measurement at both ends of the wall. Older properties in particular can be out by several centimetres across a single room, which is enough to matter when you are placing a long piece of furniture.

Step 2: Measure the bed and mark where it actually sits

Bed sizes are quoted by mattress dimensions, not frame dimensions. A double mattress is 135cm wide and 190cm long, but the frame around it may add anywhere from four to fifteen centimetres depending on the style. An upholstered or wooden frame with a thick footboard adds the most.

Measure the frame itself, including any footboard, and note how far the bed sits from the headboard wall. Beds are often pulled forward slightly by carpet grippers, radiators or skirting, and that small offset changes everything at the other end.

Step 3: Find the gap at the foot of the bed

This is the number that decides whether a bench works at all. Measure from the very end of the bed frame to whatever sits opposite: a wall, a wardrobe, a chest, or the edge of the doorway. Be strict about the finishing point. If a wardrobe door opens into that space, measure to the outer edge of the open door, not the closed one.

As a rough guide, you want 90cm or more to place a bench comfortably, and around 110cm if the route past the bench is your main walkway to an ensuite or the door.

Step 4: Subtract the walkway you need to keep

Take the gap from step three and subtract 60cm as a minimum walking allowance. What remains is the maximum depth of bench the room can take. So a 100cm gap leaves you 40cm of bench depth, which is a slim bench. A 130cm gap leaves 70cm, which allows a deeper, more generous seat or a storage box.

Do not be tempted to trim the walkway to 45cm. It sounds workable on paper, but in a bedroom where you regularly carry laundry or bedding it becomes a daily irritation, and it is the main reason benches end up being sold on.

Step 5: Set the bench width against the bed width

Visually, a bench should relate to the bed rather than match it. Two thirds to three quarters of the bed width tends to look balanced. A bench that spans the full width of the bed can work if the room is wide and the bench is low, but it often reads as a barrier and makes the bed look boxed in.

For a single bed, a small stool or a narrow bench of around 70cm is usually more appropriate than a full bench. If you are furnishing a guest room, consider whether a compact seat would be more useful than a long one. The range of modern benches UK sale shoppers browse includes sizes that suit both bedrooms and dining spaces, so check the dimensions rather than the category name.

Step 6: Check the seat height against your bed and mattress

A bench should sit level with or slightly below the top of your mattress. Measure from the floor to the top of the mattress, then look for a bench within about ten centimetres below that figure. Most beds land between 50cm and 65cm to the mattress top, and most benches sit between 40cm and 50cm, so the two usually agree.

Where it goes wrong is with divan bases and deep mattresses, which can push the sleeping surface above 70cm. In that case a taller bench or a low blanket box keeps the proportions sensible. If seating comfort is the priority, 45cm is the height most people find natural to sit on.

Step 7: Account for doors, radiators and sockets

Walk the room with the tape and note anything that intrudes into the space at bench height. Radiators are the usual culprit, particularly in rooms where the bed faces an external wall. Leaving a bench pressed against a radiator blocks heat and can dry out upholstery over time, so allow at least ten centimetres of clearance.

Check door swings as well. A bedroom door that opens inward may clear the bed but catch the corner of a bench. Sockets matter too if you charge phones or use a lamp nearby, since a deep bench can make a low socket unreachable.

Step 8: Mask out the footprint and live with it

The final step costs nothing. Mark the bench outline on the floor with masking tape using the width and depth you have settled on, then leave it for a day or two. Walk past it, make the bed, open the wardrobe and carry a basket of washing through the room.

If you find yourself stepping around the tape awkwardly, reduce the depth before you buy. This single test catches more sizing mistakes than any amount of measuring, and it is the step most people skip.

Choosing the bench once you have your numbers

With width, depth and height decided, the remaining choices are material and function. An upholstered bench adds softness to a room dominated by hard surfaces such as wardrobes and chests. A wooden or metal frame bench reads lighter visually, which helps in a room that already feels full.

If storage is short, a bench with a lifting lid or a lower shelf earns its space twice over. Many people pair one with an existing modern blanket box UK option instead, since the two overlap in purpose and a box often holds more. Think about what you actually want to put there: spare bedding, shoes, or simply somewhere to sit while dressing.

Finish is worth a thought too. Pale fabric at the foot of a bed will show marks from shoes and bags sooner than a deeper tone, and a fixed cover is harder to refresh than a removable one.

What to do if the room is too tight

Plenty of British bedrooms simply cannot take a bench, and forcing one in helps nobody. The alternatives work well. A single upholstered chair in the corner gives you the same function of somewhere to sit and put clothes, without blocking the main route. A narrow stool tucked partly under the bed frame takes almost no floor space. A pair of small ottomans can be pushed aside when not needed.

You could also move the function elsewhere. A chair at a dressing table serves the same purpose in many rooms, and some people prefer one of the modern bedroom chairs UK sale options for exactly that reason. At Furniture in Fashion we see plenty of customers make that swap once they have measured properly and accepted what the room will allow.

Frequently asked questions

How much space should be left between a bed and a bench?

Very little, if any. Benches usually sit five to ten centimetres from the foot of the bed or directly against it. The critical gap is on the other side of the bench, where you need at least 60cm to walk.

What size bench suits a king size bed?

A bench between 120cm and 140cm wide generally looks right against a king bed of 150cm. Anything narrower than about 110cm starts to look undersized in that position.

Should a bedroom bench match the bed frame?

It does not need to. Matching exactly can make a room feel like a showroom set. Repeating one element, such as the timber tone or the fabric colour, is usually enough to tie the pieces together.

Can a bench go under a window instead?

Yes, and in narrow rooms this is often the better answer. Check the radiator position first and make sure the bench back does not block the window opening or curtain fall.

Do I need to measure for carpet depth?

If you have thick carpet, add a small allowance, since furniture sinks slightly and effective heights change by a centimetre or two. It rarely affects fit, but it can affect how level a bench sits next to a hard floor threshold.
