What to Measure Before Buying a Bookcase with Doors
Share
A bookcase with doors can make a small room feel calmer almost instantly. It hides visual clutter, protects everyday items from dust, and gives books, documents, baskets, cables and personal things a more intentional place to live.
But before choosing one, there is one step that matters more than style, colour or even storage capacity: measuring your space properly.
This is especially important if you live in a flat, shared apartment, rented home or compact city space. A bookcase may look perfect online, but if the doors cannot open fully, the unit blocks a socket, or the package cannot make it through a narrow hallway, it quickly becomes frustrating.
Here is a simple, practical measurement guide to help you choose a bookcase with doors that fits your home — not just your wall.
1. Measure the wall space first

Start with the area where you want the bookcase to stand.
Measure:
- Width — the left-to-right space available
- Height — from floor to ceiling, or to any shelf, window ledge or wall fixture above
- Depth — how far the bookcase can come out from the wall
Do not only measure the empty wall. Look at what is around it. Skirting boards, radiators, sockets, light switches, curtains, window frames and nearby furniture can all reduce the usable space.
For small homes, this matters because a few centimetres can decide whether the bookcase feels neatly placed or awkwardly squeezed in.
Coleshome tip: Leave a little breathing room on both sides if possible. It makes the furniture easier to position, easier to clean around, and less stressful if you move home later.
2. Check the door swing clearance

This is the measurement many people forget.
A bookcase with doors needs space not only for the cabinet itself, but also for the doors to open. If the bookcase is too close to a bed, sofa, desk, radiator or wall corner, the doors may only open halfway.
Before buying, check:
- How wide each door is
- Whether the doors open outward
- Whether nearby furniture blocks the opening angle
- Whether handles or knobs need extra clearance
- Whether you can still reach the shelves comfortably
If the bookcase will sit in a narrow bedroom, hallway, home office corner or living room alcove, door clearance is just as important as bookcase width.
A simple way to test this is to use masking tape on the floor. Mark the bookcase depth, then mark the approximate door swing. Stand in front of it and imagine opening the doors while carrying books, folders or storage boxes.
If it already feels tight, choose a smaller unit or a different position.
3. Measure the room depth, not just the furniture depth
Depth is easy to underestimate.
A bookcase with doors may have a listed depth of 30 cm, 35 cm or 40 cm, but the room also needs space for people to walk, sit, open doors and use nearby furniture.
Ask yourself:
- Will the bookcase narrow the walkway?
- Can you still pull out your desk chair?
- Can bedroom doors or wardrobe doors still open?
- Will it make the room feel heavy or crowded?
- Can two people move around the room comfortably?
For small apartments, the best bookcase is not always the largest one. A slightly slimmer unit can keep the room feeling more open while still adding useful hidden storage.
This is where “fit” becomes more than a number. The right depth should support your daily routine, not interrupt it.
4. Measure what you actually want to store
A bookcase with doors is not only for books.
In many small homes, it becomes a mixed storage zone for:
- Books and notebooks
- Work documents
- Board games
- Baskets
- Chargers and cables
- Camera or hobby gear
- Children’s items
- Home office supplies
- Everyday things you want nearby but not always visible
Before choosing a size, measure a few of the items you plan to store. Pay attention to height, depth and how often you use them.
For example, large folders, storage boxes and binders may need deeper shelves than paperback books. Decorative items may need more open display space, while paperwork and clutter are often better behind doors.
A good bookcase with doors should help you decide what to show and what to hide. That balance is what makes a small room feel more organised without making it feel too plain.
5. Check shelf height and adjustability
Shelf height can make or break the usefulness of a bookcase.
If shelves are too low, tall books or folders will not fit. If shelves are too high, you may waste vertical space. Adjustable shelves are helpful because they let the bookcase change with your needs.
Before buying, check:
- The internal shelf height
- Whether shelves are adjustable
- The maximum shelf load, if listed
- Whether door hinges reduce usable shelf space
- Whether your tallest items can fit inside
If you are buying for a home office corner, measure your folders, printer paper, notebooks and storage boxes. If it is for a living room, measure baskets, photo albums, games and décor.
For renters and people who move often, flexibility is especially useful. Your next flat may not have the same layout, but adjustable storage can adapt more easily.
6. Look for sockets, radiators and skirting boards

The wall may look empty, but the details matter.
Before placing a bookcase with doors, check for:
- Power sockets
- Internet ports
- Light switches
- Radiators
- Pipes
- Skirting boards
- Wall vents
- Uneven flooring
- Window curtains or blinds
Do not block anything you need to access regularly. A socket hidden behind a heavy bookcase may become annoying every time you need to charge a device or plug in a lamp.
Radiators are especially important. Placing furniture too close can affect heat flow and may not be suitable for the material or finish of the furniture.
Skirting boards also deserve attention. They can stop the bookcase from sitting flush against the wall, which may affect stability and appearance.
Coleshome tip: If your home has deep skirting boards, measure from the front of the skirting board — not the wall behind it.
7. Measure the route into your home
A bookcase needs to fit through your home before it can fit in your room.
This is easy to forget when shopping online.
Check:
- Front door width
- Hallway width
- Staircase turns
- Lift size
- Internal doorways
- Tight corners
- Whether the package can be carried safely
Flat-pack furniture can make delivery and movement easier, but the package still needs to get through the route. If you live in an older building, a top-floor flat, a shared house or a narrow terrace, this step is worth doing before ordering.
Also think about where you will assemble it. You need enough floor space to lay out panels, hardware and instructions without blocking the whole room.
Coleshome tip: Coleshome storage furniture is designed with straightforward assembly in mind — helpful when your only building space is a compact bedroom, living room corner or rental flat.
This small detail matters. In a city apartment, “easy to assemble” is not just about saving time. It can also mean less stress, fewer tools, less disruption and a smoother move-in experience.
8. Check wall safety and anti-tip needs
Tall storage furniture should feel stable, especially in homes with children, pets or uneven floors.
Before buying and installing a bookcase with doors, check whether the product includes or recommends an anti-tip kit. Also look at the wall type in your home. Brick, plasterboard and concrete walls may need different fixings.
We also know that drilling into walls is not always simple for renters. Some tenancy agreements limit what you can fix to the wall, and many people do not want to risk damage in a temporary home.
That is why it is important to think about:
- Whether the bookcase has a stable base
- Whether the unit is tall and narrow or lower and wider
- Whether anti-tip fixing is recommended
- Whether your tenancy allows wall fixing
- Whether the floor is level enough for safe placement
If wall fixing is not an option, consider lower, wider or more stable furniture where appropriate. If you choose a tall unit, always follow the product safety guidance carefully.
Safety is not the most exciting part of choosing furniture, but it is one of the most important.
9. Think about future moves
Many people buying furniture for small apartments are not buying for a forever home.
You may move because of work, study, rent changes, a growing family or simply a better flat. That does not mean you should avoid good furniture. It means you should choose pieces that can handle change.
Before buying, consider:
- Is the size flexible enough for another room?
- Could it work in a bedroom, living room or home office?
- Is it too wide for most rental flats?
- Can it be disassembled if needed?
- Does the design feel simple enough to match future interiors?
For a small home, the most useful furniture often does more than one job. A bookcase with doors can act as storage, display, document organisation and a visual “calm zone” in one piece.
Coleshome tip: If you move often, avoid choosing furniture that only works in one very specific corner. A simple, practical bookcase is easier to reuse in your next home.

FAQ
What should I measure before buying a bookcase with doors?
Measure the wall width, height, available depth, door swing clearance, walkway space, shelf height, socket positions, skirting boards, delivery route and assembly area. For a bookcase with doors, door clearance is especially important.
How much space do I need in front of a bookcase with doors?
You need enough space for the doors to open comfortably and for you to stand in front of the bookcase while using it. The exact space depends on the door width and opening angle, so always check the product dimensions before buying.
Is a bookcase with doors good for a small apartment?
Yes, a bookcase with doors can work well in a small apartment because it hides visual clutter and creates a cleaner, calmer look. The key is choosing the right width, depth and door clearance for your room.
Should I choose a tall or low bookcase for a rental flat?
A tall bookcase offers more vertical storage, but it may need anti-tip fixing for safety. A lower bookcase can feel more flexible and easier to move. If you rent, check your wall-fixing rules before choosing tall storage furniture.
Why is door clearance important for a bookcase with doors?
Door clearance decides whether the cabinet doors can open fully. If the bookcase is too close to a bed, sofa, desk, wall or radiator, the doors may be blocked, making the storage harder to use every day.
