The Origins of a Design Classic
The Billy bookcase was conceived in 1979 by Gillis Lundgren, who was the fourth employee of IKEA. The inspiration for the product came from an IKEA advertising manager, Billy Liljedahl, who expressed a need for a "proper bookcase just for books." Lundgren's initial designs were famously sketched on the back of a napkin.
Lundgren focused on three core pillars: functionality, flexibility, and timelessness. He recognized that homeowners have varying space requirements and that book collections grow over time. By creating a design that was attractive yet neutral, he ensured the Billy would remain in demand regardless of changing interior design trends. The product made its official debut in the 1979 IKEA Catalogue.
Construction and Technical Specifications
The Billy is designed for efficiency and ease of transport, sold in flat-pack form for assembly by the purchaser. The primary structure consists of particle board—engineered wood made from bonded wood chips—which is then finished with either melamine coating or wood veneer.
To ensure versatility, the shelves are supported by brass flanged pins inserted into holes spaced 32 mm apart vertically. This allows users to customize the height of their shelves. The units are available in widths of 40 cm or 80 cm and can be coupled together or fitted with optional doors for a more enclosed look.

Manufacturing and Production
While produced globally, Gyllensvaans Möbler in Kattilstorp, Sweden, is a primary supplier. The scale of production is immense; in 2009, IKEA was producing approximately 130,000 bookshelves every week to meet global demand.
Evolution and Iterations
Over the decades, IKEA has refined the Billy based on customer feedback and regulatory requirements:
- 1988: The width was reduced from 90 cm to 80 cm to prevent shelves from bending under heavy loads and to better fit in-store transport pallets.
- 1992-1999: Following reports of formaldehyde vapour levels exceeding regulations due to the lacquer, IKEA halted production to fix the issue, eventually replacing the white bookcase lacquer with melamine foil in 1999.
- 2011-2014: A deeper 40 cm variant was introduced alongside the standard 28 cm depth.
- 2014: IKEA introduced rounded edges and reinforced shelves for better durability.
- 2020-2022: A major rework occurred, switching from wood veneer to paper foil and replacing metal nails with plastic fasteners.
The Billy Bookcase Index
The Billy's ubiquity is so widespread that in 2009, Bloomberg created the "Billy bookcase index." Similar to the Big Mac Index, this economic tool uses the price of a Billy bookcase in different countries to compare relative price levels and currency valuations globally.
