Furniture Making: How Wooden Furniture Is Designed, Built and Sized

Every piece of wooden furniture goes through the same stages — design, a cut list, milling, joinery, a dry fit, glue-up and finish — and every piece has to live with wood that swells and shrinks across its grain. What changes from one piece to the next is how it is built: a table on legs and aprons, a case of panels, a seat that takes a person's weight. This guide explains those stages and kinds, where the hazards lie and which furniture is regulated, and maps BenchRoot's furniture plans and sizing calculators.

Plate —The stages of a furniture build: design (sizes, joints, a drawing), a cut list of every part, milling the stock flat, straight and square, cutting the joinery to the real parts, a dry fit without glue, the glue-up, clamped and checked for square, and the finish. Wood moves across its grain at every stage, so the design allows for it; and each stage checks the last against the parts in hand, not the drawing.

The stages every piece goes through

Furniture is built in the same order whatever its size. It is designed and drawn, every part goes on a cut list, the stock is milled flat, straight and square, the joints are cut, the piece is assembled dry to prove it, then glued, and finally finished. The order matters because each stage depends on the accuracy of the one before: joinery cut on stock that is not square will not close, and a case glued out of square will never take a door that fits. The detailed order for a cabinet is in learning furniture making.

Kinds of furniture, by how they are built

Furniture by its construction, with BenchRoot's plans
KindHow it is builtPlans
TablesA top on legs joined by aprons or a trestle; the top must be free to move across its widthCoffee and side tables, dining table, trestle table, desk
CasesPanels joined into a box, with shelves, doors or drawers fitted to its openingsBookshelf, built-in bookcase, cabinet
SeatsLegs, rails and stretchers carrying a person's weight, often racked from side to sideBench, stool
BedsA frame sized to a mattress, often built to come apartBed frame
Wall piecesFixed to the wall, so the fixing is as important as the pieceFloating shelf

Wood moves, so furniture must let it

Solid wood swells and shrinks as its moisture content follows the air around it, and the Wood Handbook shows the change is far larger across the grain than along it. A tabletop or panel glued rigidly across its width will crack or push its frame apart over a year of seasons. That is why tops are fastened with slotted holes or clips, panels float in grooves, and wide solid parts are never glued cross-grain to each other. How much a given board will move is worked out in the wood movement calculator; plywood, which is cross-laminated, moves very little in its width.

Joints and materials

The joint follows the job: a mortise and tenon for a leg and rail, dadoes and rabbets for a plywood case, dovetails for a drawer or box. Choosing a wood joint compares them by load, grain and glue surface. For materials, solid wood gives edges and surfaces that can be shaped and repaired; plywood gives stable, wide panels for cases. Plywood is rarely its nominal thickness, so measure it before cutting any joint sized to it — the plywood thickness chart shows why. The board foot calculator and cut list optimizer turn a cut list into stock to buy.

Furniture that is regulated or can tip

  • Cribs and bunk beds are regulated products in the US, with federal safety standards and testing. BenchRoot does not offer plans for them or for other children's furniture.
  • Chests of drawers, dressers and armoires that meet the CPSC's size and weight thresholds fall under its tip-over standard; tall pieces of any kind should be anchored to the wall.
  • Seats carry people; BenchRoot's bench and stool plans are drawn and checked, not load-rated.

Safety— Anchor tall furniture

Bookcases, dressers and other tall pieces can tip when climbed on or when drawers are opened. Anchor them to the wall with fixings chosen from their makers' data, as the CPSC's Anchor It campaign urges. Shop rules are in woodworking safety rules.

Sizing tools and the furniture pages

Before starting a piece of furniture

  • A drawing with every part, and a cut list from it
  • Solid parts arranged so they can move across the grain
  • Real material thicknesses measured
  • A plan for anchoring anything tall
  • No crib, bunk bed or other regulated children's furniture
