Specs & tolerances

Numbers you can hold us to.

Trade or homeowner, you shouldn't have to open the box to learn what we build to. These are the envelopes the configurators accept, the tolerances the shop packs to, and the system dimensions your installer will ask about.

Dimension envelopes

Every dimension is accepted in 1 mm steps — enter millimeters or inches, the toggle converts, and the shop builds in mm. The table below is generated from the same source the configurators validate against.

Component	Width	Depth	Height	Thickness
Cabinet Box	229–3000 mm (9″–118″)	305–762 mm (12″–30″)	305–3000 mm (12″–118″)	—
Drawer Box	152–1067 mm (6″–42″)	305–610 mm (12″–24″)	51–305 mm (2″–12″)	—
Bookshelf	457–1219 mm (18″–48″)	229–406 mm (9″–16″)	762–3000 mm (30″–118″)	—
Front	152–1067 mm (6″–42″)	—	127–3000 mm (5″–118″)	19.05 mm(3/4″)
End Panel	305–762 mm (12″–30″)	—	305–3000 mm (12″–118″)	19.05 mm(3/4″)
Trim & Toe Kick	38–3000 mm (1.5″–118″)	—	38–3000 mm (1.5″–118″)	19.05 / 12.7 mm(3/4″ / 1/2″)
Hardwood Panel	152–1219 mm (6″–48″)	—	305–3000 mm (12″–118″)	19.05 / 25.4 / 31.75 / 38.1 / 44.45 mm(3/4″ / 1″ / 1 1/4″ / 1 1/2″ / 1 3/4″)
Island Legs & Posts	76–305 mm (3″–12″)	—	102–3000 mm (4″–118″)	88.9 mm(3 1/2″)

A cabinet box past 1524 mm (60″) on its height or its width gets structure added for you — a dadoed, pegged fixed shelf across the height, a vertical divider across the width — so no opening in the box is left unsupported over that span. They are drawn in the configurator and itemized in the price; the same rule a tall bookshelf's fixed shelf comes from.

Hinge-cup boring is offered on leaves up to 1524 mm (60″) tall. A taller front is built and shipped unbored: above that a leaf needs more than three cups, and we would rather say so than guess at the pattern.

Anything with an edge over 60″ routes to a freight quote rather than checkout — details on the shipping page.

Build tolerances

Solid wood moves with the seasons, so honest tolerances carry a timestamp: every number below is measured at packing, at the stated moisture content. After that, widths across the grain track your home's humidity by known amounts — the wood-movement page has per-species figures — while lengths along the grain effectively hold still.

Cut dimensions: ±0.5 mm from your confirmed numbers.
Square: assembled boxes within 1.0 mm across the diagonals.
Flatness: panels within 1 mm over any 600 mm span.
Moisture content: 6–8%, targeted to Mountain-West interiors.

A piece outside these numbers on arrival is a warranty matter, plainly. Seasonal movement inside the published envelopes afterward is the wood working as designed, not a defect.

Materials

Solid hardwood — no particleboard, no MDF, no lacquer. Panels are glued up with hot hide glue (reversible, repairable, the furniture standard for centuries). Six show species: Maple, Alder, Red Oak, Ash, White Oak, Cherry, Walnut — plus paint-grade poplar under linseed paint. Finishes are their own page.

Cabinet and drawer boxes can also be specified in 18 mm Baltic birch.

Hardware & boring

Hinge boring follows Blum's 35 mm cup system — hinges press in without tools.
Pull boring is drilled at 4.7625 or 6.35 mm (3/16″ or 1/4″), center-to-center spacing from 38 to 610 mm.
Bores keep at least 6.35 mm of wood between hole and edge — the configurator enforces it, and a layout that can't fit gets a review mark instead of a silently moved hole.
Boxes hang on the steel wall rail with built-in leveling — the guide covers mounting.

What we don't promise

Grain and color matching across separate orders. Wood from different boards, cut months apart, will not match like laminate — within one order we pull from the same stock and arrange for harmony, but nature signs every board differently. Order together what needs to live together.
