You’ve found a bargain mattress. You’ve chosen the colour. You’ve even imagined what your new bed will look like in the room.
But there’s one small thing you might have skipped—and it’s the one thing that could ruin everything.
Before you buy a bed, there’s one measurement that matters more than all the rest.
And no—it’s not the mattress size.
It’s the clearance space around your bed.
Because a double bed that fits on paper might still feel cramped in real life.
And a super king might look impressive—until you realise the wardrobe doors won’t open.
Here’s how to measure properly, avoid common mistakes, and choose a bed that actually works in your space.
- Start with the Room, Not the Bed
It sounds obvious—but most people start by shopping for a bed they like, then try to make it fit.
Start with the room.
Clear out what you can. Measure the floor. Sketch it roughly.
Mark where the windows, radiators and plug sockets are.
Then ask:
- Where will the bed go?
- How much space is there around that area?
- What’s the maximum width and length you can get away with?
Only then should you start looking at frame styles and mattress sizes.
- Measure Walk-Around Space (Not Just the Frame)
You need space to move.
Not shuffle sideways. Not climb across the mattress.
Actual walking room.
The magic number?
Allow at least 60cm on either side of the bed (and at the foot if possible). That gives enough space to walk, change sheets, and pull out drawers.
If your room can’t manage that, look at:
- A smaller frame with the same mattress size (e.g. no footboard)
- A bed with built-in storage so you can skip the extra furniture
- A low-profile style to reduce visual bulk
- Check Door and Drawer Clearance
So you’ve squeezed in the bed—but now the wardrobe door hits the frame. Or your drawers can’t open fully.
Or worse—your bedroom door only opens halfway before it bangs into the corner of the bed.
Avoid this by measuring:
- How far your doors swing open
- The full extension of any drawers or storage
- Whether you’ll be able to open bedside tables without bumping into things
If it’s tight, look for sliding doors, or consider a divan with side drawers on one side only.
- Don’t Forget Height
Some beds are higher than they look in photos. Others sit low and vanish into the floor.
Before you click ‘buy’, check:
- Height from floor to top of the mattress
- Height of the headboard (especially in rooms with sloped ceilings or windows)
- Whether you’ll want under-bed storage—and if it will fit
In small or low-ceilinged rooms, a lower bed helps the room feel taller.
In larger spaces, a taller headboard can anchor the space and add drama.
- Think About What’s Behind the Bed
A window? A radiator? An ornate classic fireplace? A sloped ceiling?
You need to check what is behind where the bed will sit.
Tall headboards don’t mix well with shutters or low window sills.
Radiators can warp fabric headboards over time—or make winter nights uncomfortable if blocked.
In awkward layouts, go for:
- A wooden bed with an open slatted headboard
- A low padded frame
- A daybed-style base that sits snugly against walls
- Use Tape to Mark It Out
One of the best tricks?
Use masking tape on the floor to mark the actual size of the bed frame—not just the mattress.
This lets you:
- Walk around it
- Test drawers
- Check how it looks with other furniture
It’s the closest thing to trying the bed before you buy it.
- Bigger Isn’t Always Better
A bed that’s too big overwhelms the room.
A bed that fits just right makes the space feel calm and inviting.
And the right bed—one you’ve measured for—will give you:
- Room to breathe
- Space to store
- Comfort without compromise
The Bottom Line
Before you get carried away choosing colours and styles, measure properly.
Not just the mattress. Not just the frame.
Measure the space your body will actually need to move, live, and breathe around the bed.
Because comfort isn’t just about sleep—it’s about how the whole room works around you.
