How to Lay Out a Home Library

A library is hired by its shelving: the room is a storage system you sit inside. The design questions are structural before they are decorative — how many linear metres of books exist (measure them; everyone guesses low), whether the floor takes the load (a full wall of books is a grand piano’s weight), and where the reading happens once the walls are working. Get the metres, the weight and the chair right, and the atmosphere arrives by itself; no room styles itself as reliably as one lined with real, read books.

Count linear metres of books, add 30% for growth: that number sizes the room. Shelves: 28–32cm deep, 30–35cm vertical spacing for most books, one taller run for art books. Aisle in front of shelving: 75cm to browse, 100cm where two people pass. The reading chair earns the window; its lamp goes over the shoulder at 100–110cm.

The pieces that earn their floor in a home library: shelving as architecture — to the ceiling, around the door if needed; one serious reading chair per regular reader; a library table or broad ottoman for the open-face pile; a ladder or step that belongs to the room; curtains: sun is the enemy of spines. Position the first before the second exists — each anchor constrains the next, and reversing the order is how rooms end up designed around their least important piece.

Decorative shelving depth (20cm) that fits paperbacks and nothing else. Books arranged by colour by someone who then cannot find anything — the room is for reading, not for the reel. No table, so open books colonise the chair arms and floor. South sun on the good spines, fading a collection by increments.
