Zoning a studio apartment

The four zones and what each one costs in floor#

Every studio has to hold four activities. Each has a minimum rectangle, and the rectangle includes the space your body needs around the furniture, not just the furniture.

Zone	Furniture	Access allowance	Zone rectangle	Area
Sleep	Queen 60 x 80 in (152 x 203 cm)	20 in (51 cm) one side, 16 in (41 cm) at the foot	80 x 96 in (203 x 244 cm)	53 sq ft (4.9 m2)
Sitting	Sofa 80 x 35 in (203 x 89 cm)	16 in gap, 20 in table, 25 in standing room	84 x 96 in (213 x 244 cm)	56 sq ft (5.2 m2)
Eating	36 in (91 cm) round table	36 in (91 cm) all round for chair pull-back and passing	108 x 108 in (274 x 274 cm)	81 sq ft (7.5 m2)
Work	Desk 48 x 30 in (122 x 76 cm)	40 in (102 cm) behind for the chair	48 x 70 in (122 x 178 cm)	23 sq ft (2.1 m2)
Total				213 sq ft (19.8 m2)

The eating zone is the shock. A 36 in round table is small, but the 36 in of clearance it needs on every side triples it into the largest zone in the flat, larger than sleeping. That single fact drives almost every good studio plan: the dining zone is the one that has to overlap with something else. The full pull-back and passing figures are in dining clearances.

Zoning devices, ranked by the inches they cost#

Every divider is a tax on floor area. Pay it knowingly.

Device	Depth cost	Floor cost over a 12 ft (3.66 m) run	Visual block	Gives anything back?
Rug boundary	0 in	0 sq ft	None	No
Furniture turned back-to-zone	3 in (8 cm)	3 sq ft (0.28 m2)	To 32 in (81 cm) high	No
Sliding panel on a track	3 in (8 cm) plus a parking bay	3 sq ft, plus the bay	Full when closed	No
Ceiling curtain track	4 in (10 cm)	4 sq ft (0.37 m2)	Full when drawn	Modest acoustic damping
Half wall, 42 in (107 cm) high	5 in (13 cm)	5 sq ft (0.46 m2)	To 42 in	A 5 in ledge
Open shelving unit	12 to 16 in (30 to 41 cm)	14 sq ft (1.3 m2)	Partial, and adjustable	55 to 65 cu ft of storage
Stud partition, full height	5 in (13 cm)	5 sq ft (0.46 m2)	Total	Nothing, and it kills the diagonal

A curtain's real cost is not the 4 in of track. It is the stack: a pair of curtains across a 10 ft (3.05 m) opening at 2x fullness stacks into 12 to 18 in (30 to 46 cm) at each side when open, and that stack has to live somewhere. Set the track 12 in (30 cm) past the opening on each side or the curtain never fully clears. The curtain width and fullness page has the stack arithmetic.

Keep one sightline long#

The single most effective move in a studio is negative: refuse to interrupt the longest diagonal in the room. Perceived size tracks the deepest available view, and the deepest view in any rectangle is corner to corner.

The gain is worth measuring, because it is not constant:

• A 16 x 25 ft (4.9 x 7.6 m) studio has a 29.7 ft (9.1 m) diagonal against a 25 ft longest wall. The diagonal is 19 per cent longer.
• A 20 x 20 ft (6.1 x 6.1 m) studio has a 28.3 ft (8.6 m) diagonal against a 20 ft wall. The diagonal is 41 per cent longer.

The squarer the plan, the more the diagonal is worth and the more damage a cross partition does. In a long narrow studio you are only losing 19 per cent by chopping across it, which is why a curtain across a narrow studio often reads as fine and the same curtain in a square one feels like a cell.

The practical rule: stand in the entry, find the far corner, and keep everything below 42 in (107 cm) along that line. Tall objects go on the flanks.

400, 500 and 600 sq ft worked through#

400 sq ft (37 m2), 16 x 25 ft#

The budget: 400 sq ft gross, less a 40 sq ft bathroom, a 45 sq ft kitchen with its aisle, a 12 sq ft entry and a 15 sq ft closet, leaves about 288 sq ft. The four zones need 213 sq ft. A 36 in circulation spine down 25 ft of length takes 75 sq ft. 213 plus 75 is 288. There is no slack at all, which is the honest answer to "can four zones fit in 400 sq ft": yes, and nothing else can.

So one zone shares. The dining table is the obvious candidate: put it against the kitchen end where its 36 in clearance overlaps the kitchen aisle you already paid for, which recovers roughly 27 sq ft.

500 sq ft (46 m2), 20 x 25 ft#

The extra 100 sq ft is the difference between a plan and a life. It buys a genuine sitting zone with a facing chair, a dining table that seats four rather than two, and about 90 sq ft of slack. This is the size at which a shelving divider between sleep and living becomes affordable in floor terms, and at which the bed can sit in a proper alcove rather than in the room.

600 sq ft (56 m2), 20 x 30 ft#

At 600 sq ft you can build something. A 5 in stud partition returning 8 to 10 ft (2.4 to 3.0 m) from one wall creates a sleeping alcove with a 36 in (91 cm) opening, and the diagonal survives because the partition runs parallel to it rather than across it. Below 500 sq ft, do not build; divide with furniture that stores things.

Hiding the bed, with the real dimensions#

Option	Closed	Open	Ceiling needed	Honest verdict
Vertical murphy, queen	16 to 18 in deep, 64 to 68 in wide (41 to 46 x 163 to 173 cm)	Projects 86 to 90 in (218 to 229 cm)	92 to 96 in (234 to 244 cm)	Best floor recovery of any option
Horizontal murphy, full	18 to 20 in deep, 84 to 88 in wide (46 to 51 x 213 to 224 cm)	Projects 62 to 68 in (157 to 173 cm)	60 to 66 in (152 to 168 cm)	The low-ceiling answer
Daybed with trundle	30 to 33 in deep, 79 in long (76 to 84 x 201 cm)	Trundle needs 40 in (102 cm) of side access	None	No daily effort, but a 30 in mattress is a compromise
Sofa bed	38 to 42 in deep (97 to 107 cm)	Projects 80 to 90 in (203 to 229 cm)	None	Costs 5 in of sofa depth every day of the year
Loft bed	40 x 80 in (102 x 203 cm) footprint	Static	100 in (254 cm)	Frees 22 sq ft beneath, if your ceiling allows
Platform with drawers	60 x 80 in (152 x 203 cm)	Drawers project 24 in (61 cm)	None	Only where you have 28 in of clear side floor

The murphy bed cabinet is the number people get wrong. 16 to 18 in (41 to 46 cm) closed sounds trivial until you notice it runs 64 to 68 in wide, so the cabinet's plan footprint is about 8 sq ft, and the wall it stands against is then unavailable for anything else, ever. It buys back the 53 sq ft sleep zone for 15 hours a day. That is a good trade in 400 sq ft and a poor one in 600.

Full comparisons of the opened states are in multi-function furniture, and bed sizes against room sizes are in bed sizes and the rooms that take them.

Storage per person, and the entry#

Allow 25 to 35 cu ft (0.7 to 1.0 m3) of clothing storage per adult. Converted into things you can buy: one linear foot of 24 in (61 cm) deep hanging with a 42 in (107 cm) drop is about 7 cu ft, so the allowance is 4 to 5 linear feet of rod, or 3 linear feet of rod plus four drawers at roughly 2 cu ft each. Add household and seasonal storage separately; the item-by-item figures are in storage dimensions.

The entry needs a 36 x 36 in (91 x 91 cm) landing clear of the door swing. This is the zone every studio plan deletes and every studio resident recreates by dropping bags on the floor. Give it 36 in square, a 24 in (61 cm) run of hooks or rod, and a hard surface at 30 to 34 in (76 to 86 cm) high for keys. Twelve square feet, and it stops the whole flat from silting up at the door.

The order to solve it in#

1. Mark the entry landing, 36 x 36 in, and the door swing.
2. Draw the longest diagonal from the entry corner. Nothing above 42 in high crosses it.
3. Place the sleep zone furthest from the entry, at its full 80 x 96 in.
4. Place the work zone at the best window, at 48 x 70 in. It needs daylight more than the sofa does.
5. Place the sitting zone, then decide what it faces.
6. Give the dining zone whatever is left and overlap its clearance with the kitchen aisle.
7. Only now choose the divider, and choose the one with shelves in it.

If step 6 fails, the dining zone becomes a 30 x 48 in (76 x 122 cm) table pushed to a wall with two chairs, which needs 30 in of clearance on the open sides instead of 36 in all round, and costs 30 sq ft rather than 81.
