Shoe storage dimensions: depth, pitch and capacity

Almost every shoe rack in a hallway is too shallow, for a reason that has nothing to do with shoes. It is 10 or 11 in (25 to 28 cm) deep because that is what fits past the door swing, and the shoes are expected to cope. They do not: they sit at an angle, heels hang over the front edge, and the bottom shelf becomes a pile.

The two lengths people confuse#

A shoe is not a foot. A marked shoe size describes the foot inside, and the shelf has to hold the outsole, which is longer. The last a shoe is built on runs roughly 1/2 to 3/4 in (13 to 19 mm) past the toes for fit and shape, and a moulded sport sole adds another 1/4 to 1/2 in (6 to 13 mm) of toe bumper on top of that. A men's US 10 foot is about 10.9 in (27.7 cm) long. The dress shoe it wears measures about 12 in (30.5 cm) on the floor, and the running shoe about 12.4 in (31.5 cm). The gap between the size on the box and the space on the shelf is around 1.5 in (38 mm), and that is the whole difference between a shelf that works and one that does not.

Two datums matter, and both are inside faces:

• Shoe length is measured with the shoe standing on the floor on its own sole, from the back of the heel counter to the front of the toe bumper, with a straightedge held vertically at each end. Not the insole, not the box.
• Shelf depth is measured from the inside face of the back panel to the inside face of the closed door, not the outside of the carcass. A 15.5 in (39 cm) cabinet with a 3/4 in (18 mm) back and a 3/4 in door is a 14 in (36 cm) shelf, which is the number to plan with. The same distinction governs every figure in shelf depth and vertical spacing by content.

Outsole length by shoe size#

Foot lengths follow the Mondopoint basis used in ISO 9407, where the size is the foot length in millimetres. The outsole columns are working figures from catalogue shoes rather than a published standard, and a heavy hiking boot beats the trainer column by another 1/2 in (13 mm).

Where 12 and 14 in come from#

Take the largest shoe most households actually own, a men's US 12 trainer at 13.2 in (33.5 cm), and build the shelf around it:

• 13.2 in of shoe
• plus 1/2 in (13 mm) so the toe does not press on the back panel
• plus 1/2 in (13 mm) so the heel sits clear of a closing door
• = 14.2 in (36 cm) of clear depth

Round to 14 in (36 cm) and accept that a men's 14 trainer touches at both ends. Now run the same sum for a men's US 10 dress shoe at 12 in (30.5 cm): 12 plus one inch of clearance gives 13 in, and the usual 12 in (30 cm) shelf is already half an inch short. That half inch is why shoes on a 12 in shelf sit with their heels proud of the front edge, and why the door of a 12 in cabinet nudges them every time it shuts.

So the honest advice is not one number but two. Twelve inches (30 cm) is the minimum that works for a household of average sizes and dress shoes. Fourteen inches (36 cm) is the number that works for everybody, including trainers. Anything under 11 in (28 cm) has to store shoes at an angle or on edge, which is a different design and is dealt with below.

Pitch: the number that actually sets capacity#

Clear height between one shelf surface and the underside of the next is the variable that decides how many shelves fit in a wall, and it is set by the tallest shoe in the category, laces and all.

An 84 in (213 cm) tall unit at 8.25 in (21 cm) centres holds 10 shelves. Built to take ankle boots on every shelf, at 10.75 in (27 cm) centres, it holds seven. Three shelves, or 30 per cent of the storage, is the price of making every shelf tall enough for the one pair of boots that could have gone at the bottom.

Capacity: pairs per linear foot#

Shoe width is the forgotten dimension. Measured across the ball, a men's shoe in a standard width is close to 4 in (10 cm) and a women's close to 3.5 in (9 cm), and you need about half an inch of air between pairs to lift one out without knocking the next.

Multiply through and a wall gets honest very quickly. A unit 36 in (91 cm) wide and 84 in (213 cm) tall, with seven shoe shelves at 8.25 in centres and one boot bay, holds seven times four pairs, so 28 pairs on 3.5 sq ft (0.33 m2) of floor. Nest the pairs and the same box takes about 42 pairs. That is the number to compare against the pile by the door, and it is a fair test of whether a hall unit earns the depth it takes out of the walkway width.

For a whole household, our own working allowance is 10 to 14 pairs per adult in the entry, with the rest in a bedroom reach-in closet or under a bed. England's nationally described space standard counts built-in storage inside the floor area a new home must provide, starting at about 1 m2 (11 sq ft) for a one or two person dwelling.

Boots, wet shoes and the bottom bay#

Boots need height, not depth: a knee boot has the same footprint as the shoe of the same size. Upright it wants 18 to 20 in (46 to 51 cm) of clear height and a shaper, or the shaft folds and the crease is permanent. Laid on its side a pair occupies about 15 x 12 in (38 x 30 cm), which is why a deep bottom drawer often beats a tall bay.

Wet footwear is the other reason the bottom bay should differ from the rest. A drip tray 30 x 15 in (76 x 38 cm) with a 3/4 in (19 mm) upstand holds the runoff from two pairs of walking boots, and it wants air: a closed cabinet with wet boots in it stays wet for days and passes the damp upward. Leave the lowest bay open and keep a 1 in (25 mm) gap at the back of every shelf. The same principle drives mudroom sizes and layouts, where drying is the primary job and storage is second.

Height matters for reach as much as for boots. Daily pairs belong between 6 in (15 cm) and 54 in (137 cm) above the floor, the band described in reach zones and useful storage heights; above about 60 in (152 cm) you are reaching into a shelf you cannot see the floor of, which is where the out-of-season boxes go.

Fitting the unit into the hall#

Depth in a hallway is borrowed from the walkway, and the borrowing has a floor. A primary route wants 36 in (91 cm) clear, and a secondary route 30 in (76 cm). In a 42 in (107 cm) hall a 14 in (36 cm) deep shoe cupboard leaves 28 in (71 cm), which is below both. The same hall takes a 10 in (25 cm) tilt-out cabinet with 32 in (81 cm) to spare, and that trade is the entire reason tilt-out cabinets exist.

Two more dimensions decide whether the unit is usable rather than merely present. A 24 in (61 cm) hinged door sweeps 24 in into the hall, so under 48 in (122 cm) of hall width use sliding doors, flaps or none. And there has to be somewhere to stand while changing shoes: allow 30 x 24 in (76 x 61 cm) of clear floor in front, or put a seat there, since a bench with cubbies under it does two jobs in one footprint. Heights are in entry bench, hook and cubby heights.

If the shoes are going into an existing cupboard, check what the depth is doing first. A 24 in (61 cm) deep coat closet has 10 in (25 cm) of unused depth behind a shoe shelf, enough for a second nested row or a pull-out. Runs longer than about 30 in (76 cm) also need checking for sag once loaded, because shoes are heavier than they look at 2 to 3 lb (0.9 to 1.4 kg) a pair.

Modules that are worth building to#

Our own preference is a 36 in (91 cm) wide bay, 14 in (36 cm) deep, with adjustable shelf holes at 32 mm (1.26 in) centres so the pitch can move between 6 and 10 in as the household's shoes change. That is the same 32 mm system carcase joinery uses everywhere, and the terms are defined in the glossary. Three bays make a wall; one makes a cupboard under the stairs honest.

For the whole entry rather than one cupboard, the wardrobe and closet planner runs the shelf arithmetic against a given carcass, and the layout logic for the first 6 ft (1.8 m) of a house sits in the entryway section.
