A sourced reference library of standard product dimensions — furniture, logistics and building materials — with sizes in metric and imperial from ISO, ANSI, EN and established industry standards, plus how to mark them on your product photos.
A standard three-seat sofa is about 180–230 cm (71–90 in) wide, 85–95 cm (33–37 in) deep and 75–90 cm (30–35 in) tall. Two-seat loveseats span 140–180 cm (55–71 in); four-seaters reach 230–300 cm (90–118 in).
Standard dining tables are 28–30 in (71–76 cm) tall. A 6-seat rectangular table is about 60×36 in (152×91 cm), an 8-seat 72×42 in (183×107 cm), a 10-seat 96×44 in (244×112 cm). Allow 24 in (61 cm) per diner.
Standard US mattress sizes are Twin 38×75 in, Full 54×75, Queen 60×80, King 76×80 and California King 72×84 in. UK sizes are metric and differ: Single 90×190 cm, Double 135×190, King 150×200 and Super King 180×200 cm.
A standard desk is 71–76 cm (28–30 in) tall — about 73.7 cm (29 in) — and 122–183 cm (48–72 in) wide by 61–76 cm (24–30 in) deep. Sit-stand desks adjust 56–122 cm (22–48 in) per ANSI/BIFMA G1.
A standard bookshelf is about 80 cm (31.5 in) wide, 28 cm (11 in) deep and 202 cm (79.5 in) tall (IKEA Billy). Library shelves run 20–30 cm (8–12 in) deep with at least 20 cm (8 in) between shelves.
Standard wardrobes are 50–60 cm (20–24 in) deep — hanging needs ~58 cm. Single-door units are 76–102 cm (30–40 in) wide, double-door 122–152 cm (48–60 in), and 183–213 cm (72–84 in) tall. IKEA PAX frames come 50/75/100 cm wide.
A standard ergonomic office chair follows BIFMA G1: seat height adjusts 37.6–51.2 cm (14.8–20.2 in), seat width ≥48.9 cm (19.2 in), seat depth ≤41.5 cm (16.3 in), backrest ≥35.4 cm (13.9 in), and armrests roughly 18–29 cm (7–11.5 in).
Standard coffee tables are 41–46 cm (16–18 in) tall — level with the sofa seat — and about 122 × 61 cm (48 × 24 in). Size the length to two-thirds of the sofa and leave 36–46 cm (14–18 in) of legroom.
ISO 6780 defines six pallet sizes. The most common regional standards are North America's GMA pallet (48×40 in / 1219×1016 mm), Europe's EPAL Euro pallet (1200×800 mm), Asia's 1100×1100 mm, and Australia's 1165×1165 mm.
Standard shipping containers follow ISO 668: a 20ft is 6.06 m long, 2.44 m wide, 2.59 m high (33 m³); a 40ft doubles length to 12.19 m (67 m³); a 40ft High Cube raises height to 2.90 m (76 m³).
A standard 55-gallon (208-litre) steel drum measures about 572 mm (22.5 in) internal diameter and 851–880 mm (33.5–34.7 in) tall; ISO 15750 fixes the internal diameter at 571.5 mm. Capacity is nominal, and outer dimensions vary slightly by maker.
A standard 1,000-litre (275-gallon) caged IBC tote measures 1,200 × 1,000 × 1,160 mm (47.2 × 39.4 × 45.7 in, L×W×H) on a 4-way pallet; the taller 1,250-litre (330-gallon) version stands 1,350 mm (53 in) high.
Corrugated cartons are measured Length × Width × Depth (internal dimensions). There is no universal size table — boxes are made to order — but the form is standardized by FEFCO style codes (0201 RSC is the most common) and A/B/C/E/F flute grades.
In the US, standard interior doors are 80 in (2032 mm) tall with widths of 24–36 in; the typical entry door is 36×80 in. In the UK, the most common internal door is 1981×762 mm (6'6" × 2'6").
Ceramic and porcelain tiles use standard nominal formats — 300×300, 300×600, 600×600 and 600×1200 mm (12×12 to 24×48 in) — plus large-format slabs to 1600×3200 mm; wall tiles run 6–8 mm thick, floors 8–10 mm.
Standard plywood sheets measure 4×8 ft (1220×2440 mm). Baltic birch comes as a 5×5 ft square (1525×1525 mm) and European mills use 2500×1250 mm. A nominal 3/4-inch panel is actually 23/32 inch (~18.3 mm).
A 2x4 is nominal, not actual — a surfaced (S4S) piece of dimensional lumber actually measures 1 1/2 × 3 1/2 in (38 × 89 mm), because softwood is sawn oversize then dried and planed smooth, shrinking on every face.
The UK/EU standard brick is 215 × 102.5 × 65 mm — or 225 × 112.5 × 75 mm with a 10 mm mortar joint. The US modular brick is 8 × 4 × 2 2/3 in nominal, about 7 5/8 × 3 5/8 × 2 1/4 in (194 × 92 × 57 mm) actual.
Under the US IRC, stairs need a maximum 7 3/4-inch (196 mm) riser, 10-inch (254 mm) tread, 36-inch (914 mm) width and 6-ft-8 (2032 mm) headroom. UK Part K caps private-stair rise at 220 mm, going 220 mm minimum, pitch 42°.
Standard kitchen countertops sit 914 mm (36 in) above the floor, run about 635–648 mm (25–25.5 in) deep over a 610 mm (24 in) base cabinet, and use a 2 cm or 3 cm (3/4–1 1/4 in) stone slab, with a 25–38 mm (1–1.5 in) overhang.
