Wine Rack Dimensions: Module Size, Tier Height and Capacity

The dimension you do not get to choose

Every rack is a grid, and a grid is defined by its pitch: the distance from the centre of one bottle to the centre of the next. Pitch is not a style decision. It is the diameter of the widest bottle the rack has to take, plus a working gap.

That makes the third dimension a consequence. Fix the pitch and the width and height needed for a given bottle count are already decided. Change the bottle mix and the same nominal capacity needs a bigger rack.

The pitches we build to are 3.5 in (90 mm) for Bordeaux-led storage, 3.75 in (95 mm) for mixed, and 4 in (100 mm) for Champagne-led. A magnum wants 4.3 in (110 mm).

Module sizes by bottle count

The table is centre-to-centre sizes at a 3.5 in (90 mm) pitch. It is arithmetic, not a catalogue — any bottle count can be built — these are the ones that come up most often.

• Capacity grows in two directions, and the widths are not linear.
• Going from 32 to 50 bottles adds no width at all — only a row.
• Going from 40 to 60 adds a column and a row, and 7 in of wall.

Add the frame before you check the wall

The table is measured between the centres of the outside bottles. A stainless rack adds roughly 1 in (25 mm) of frame on each side plus the thickness of whatever it hangs from, so a 21 in module is close to 23 in overall.

That 2 in matters when a run has to land in a recess. It matters less on an open wall, where a scribe filler absorbs the difference at the end of the run.

Tier height, and why the top row is different

Tier height is the vertical pitch. For stacked storage it matches the horizontal pitch, because the constraint is the same bottle diameter. It stops matching at the top row.

The top row is loaded from above and in front, so the clearance over the top cradle is not a pitch — it is a pair of hands. Under a soffit or a shelf, plan on 6 to 8 in (150 to 200 mm) of working clearance, or accept that the top row is display only.

A floor-standing rack is different again at the bottom. A base row sitting at floor level collects whatever the floor collects, so the first pitch usually starts one pitch up, on a plinth. That plinth is part of the overall height, which is why a 5-row rack is not five times 3.5 in tall.

Wall-mounted racks: the numbers that go on the wall

A wall rack puts its load into the wall at the fixings, and the fixings are set by the rack width, not by the bottle count. The usual pattern is a fixing at each end plus fixings across the width, into studs or into a substrate rated for the load.

Rack width should land on the stud layout where it can. A 42 in rack on 16 in stud centres catches three studs; a 35 in rack catches two or three depending on where it starts. On a masonry wall this stops mattering, which is one reason masonry is easier.

Height above floor is a reach decision. The top row should sit at or below about 72 in (1830 mm) so a bottle can be lifted out with both hands, and the bottom of a wall rack is normally kept clear of the floor for cleaning.

Floor racks and runs: footprint and what has to stay clear

A floor rack is a footprint plus an aisle. The footprint comes from the table above. The aisle is what makes it usable, and it is the number most often left out of a plan.

In front of a rack you stand and face, 30 to 36 in (760 to 915 mm) is comfortable and 24 in is the point at which you start turning sideways. Where there is a door, the swing adds to that rather than replacing it.

In a run, depth is set by the bottle as it is on any cabinet. Two racks back to back double the capacity at the cost of one aisle, which is usually a better trade than one long single-sided run.

Working out how many racks a wall takes

Take the clear wall length, subtract the end clearances, and divide by the module width including frame. Then do the same for height, remembering the top clearance and the plinth.

Do the division at the pitch you will actually build to. A wall that takes four 42 in modules at 3.5 in pitch takes three of them at 4 in pitch, and the difference is 24 bottles.

This is the calculation to run before choosing a finish, because the finish is what makes people commit to a number that does not divide.
