Kallax vs Eket for a 2-Metre Record Shelf That Holds 900 LPs

The arithmetic before the cabinet choice

At 3.5 mm average spine width, 900 LPs take up 3.15 linear metres of shelf. A 2-metre external run cannot carry that as one uninterrupted row, so the storage has to be split across stacked shelves. A four-column Kallax laid horizontally gives 8 compartments within a 147 cm width. Each cube takes about 33 cm of records, which works out to roughly 90 to 94 discs at a typical spine width. Eight cubes land around 720 to 750 records.

The 2x4 Kallax, at 147 x 147 cm, gives 8 usable cubes and reaches about 750 records with enough space to browse. If every compartment is packed hard, the number can move toward 850, although flipping through a full cube stops being pleasant. Reaching 900 means adding a 1x4 Kallax above it, taking the overall height to roughly 190 cm, or using another system with more individual cavities inside the same wall run.

A record collection at this size is heavy enough to control the design. With jacket included, 900 LPs average about 250 grams each, so the full load sits near 225 kg. Spread through 10 to 12 compartments, that load is manageable. Put the same mass on a couple of long unsupported shelves and the shelf material starts to govern the result.

Eket: short cubes behave very differently from wide modules

Eket cabinets come in 35 x 35 cm and 70 x 35 cm footprints, with 25 cm and 35 cm depth options. The 35 cm deep unit clears a record jacket with about 3.5 cm to spare, giving a little more working depth than Kallax. The wider Eket cabinet is the part that needs care: a 70 cm unsupported horizontal shelf filled with LPs carries close to 25 kg across melamine-faced particleboard, and IKEA rates that material conservatively. After months under that kind of sustained load, a 70 cm span can bow by a few millimetres, enough to show against a level line.

Eket works best when the load goes through the suspension rail into the wall. A floating 2-metre run of 35 cm cubes at chest height looks cleaner than a floor-standing block, and the rail removes the shelf-sag issue when it is fixed into timber studs rather than plasterboard alone. A 2-metre wall run made from six 35 cm cubes plus a 70 cm unit gets close to the 900-record target once two rows are stacked, with the wall carrying the 225 kg load instead of the floor.

The 35 cm cubes avoid the sag problem because the span is so short. More cubes are required, and every joint between cabinets costs a few millimetres of usable width. Fourteen 35 cm cubes in a 2x7 wall arrangement clear 900 records comfortably, with each cube holding 95 to 100 records on a short, rigid shelf.

Kallax under real load

Kallax remains the safer floor-standing choice for records because its internal dividers do structural work. Every 33 cm cube is enclosed on all four sides, so no shelf has more than a 33 cm unsupported span. That geometry explains why a 2x4 Kallax tolerates dense vinyl weight where a wide open bookcase would struggle.

IKEA rates each Kallax compartment for a maximum load that comfortably exceeds a packed LP row. The closed-box construction helps that rating translate into normal use, since the dividers support the loaded shelves at close intervals.

A standing 2x4 unit still needs anti-tip fixing, whatever the load. With 225 kg of records inside, the centre of gravity rises as the upper cubes fill. A wall anchor through the top rail into a stud is a necessary restraint at that height and mass.

The supplied restraint strap is adequate when it is fixed into timber. It becomes marginal in plasterboard even with the correct cavity anchor, and it is useless when screwed into plasterboard alone. The purpose of the strap is to stop rotation if the cabinet starts to pivot, not to carry the shelf load.

Assembly accuracy matters more once the cabinet is full. The thin hardboard back is not structural, so a frame that racks slightly out of square will show it through cube openings that no longer line up cleanly. Build the unit on a dead-flat floor, keep the frame square, and drive the back-panel pins fully home before records go in.

Once 225 kg has been loaded, correcting a racked frame means unloading the cabinet. The small assembly errors that can be ignored on a light bookcase become visible when every cube is packed with dense vinyl.

Depth is the Kallax weakness beside Eket. With 39 cm external depth and about 33 cm inside, a 31.5 cm jacket has less than 2 cm of clearance. Records pushed flush to the rear leave very little fingertip gap, so pulling a disc from the back of a packed cube can mean fishing for the jacket edge. Most owners live with it, but the deeper Eket feels more forgiving when the two are used side by side.

Birch plywood changes the face of both systems

Both systems arrive in melamine foil finishes that can read as budget under raking light. Adding 18 mm birch plywood to the visible faces is the quickest visual upgrade. On Kallax, the plywood usually acts as cosmetic cladding: strips or panels are cut for the front edges and any exposed side, then glued and pinned to the melamine carcass. On Eket drawer and door variants, birch plywood fronts can replace the foil-wrapped panels entirely.

Utrusta hinges carry Eket and Sektion door fronts, and a heavier birch ply door alters the hinge setup. The Utrusta adjustment guide uses three screws per hinge. The rearmost screw adjusts depth, the centre screw adjusts height, and the front screw adjusts the side-to-side gap. An 18 mm birch door is denser than the original foil panel and may settle a fraction lower during the first fortnight. A quarter turn upward on the height screw is often enough once the door has been hung and loaded.

Adjustment should be done with the door on the cabinet. Bench alignment does not show how the extra weight sits once the hinge is carrying it, and a loaded door gives the screw positions a truer reference.

The exposed plywood edge decides whether the upgrade looks deliberate. Birch plywood shows its laminated layers, so the edge can become a visible stripe if it is cut and finished cleanly. A 45-degree chamfer or a simple sanded roundover taken to 180 grit presents the laminations neatly. A sawn, splintered edge will still look rough after finish is applied.

Osmo Polyx on raw birch

Osmo Polyx-Oil 3062 in clear satin suits birch ply because it penetrates the surface. Two thin coats applied with a lint-free cloth and buffed within 20 minutes before the oil grabs leave a finish that resists coffee-cup ring marks and the static-charged dust that vinyl attracts.

A filmed polyurethane over birch ply tends to yellow. Scratches are also harder to deal with once the film is broken, while the Osmo oil can be touched in with a small dab and a rub, without sanding back to bare wood.

Coverage is around 24 square metres per litre in two coats, so a 750 ml tin finishes the fronts of a full Kallax or Eket record wall with material left over. Handling hardness takes 8 to 10 hours at room temperature. Full cure before heavy load contact wants closer to a week, since loading 225 kg of records against a front cured only overnight can leave a faint oil transfer on the jacket edges.

The exact 900-record build

For a 2-metre wall, 900 records, and birch ply fronts, the floor-standing build is a 2x4 Kallax of 147 cm plus a 1x4 Kallax stacked above it. The height reaches roughly 190 cm and the layout provides 12 compartments. At 90 records per cube, nominal capacity is 1080 records, so 900 leaves about 25 percent of each cube open for easier browsing. Material cost sits in the mid range, and the anti-tip fixing into a stud is mandatory at that height and mass.

The wall-hung build uses fourteen 35 x 35 cm Eket cubes in a 2x7 grid on the suspension rail. Butt them together and the run spans exactly 2 metres, with a slightly wider overall dimension if reveal gaps are left between cubes. Fourteen cubes at 95 records each reach 1330 nominal capacity, putting 900 records at 68 percent fill. The rail has to land on at least three studs across the 2-metre width to carry 225 kg. With standard 400 mm or 600 mm stud spacing, that is achievable with a stud finder and honest fixings, not drywall plugs.

On masonry or solid timber, the floating Eket arrangement is the cleaner answer and the rail takes the load out of any 70 cm modules that might otherwise sag. A plasterboard wall over metal studs changes the installation. The records stay on a floor-standing Kallax, and the wall connection is reduced to a restraint strap. At that point the anti-tip strap is doing only restraint work while the floor carries the collection.
