Hardback, paperback and oversize: what fits where
Hardback, paperback and oversize: what fits where
Book sizes are not standardised the way paper sizes are, but they cluster into a handful of trim sizes that publishers reuse. Knowing them saves two disappointments: a book that will not fit the shelf it was bought for, and a storage box that will not take the books it was bought for.
The sizes you will actually meet
Measurements are height by width, in inches, and vary by a fraction between publishers.
- Mass-market paperback — about 6.75 × 4.25. The rack-sized paperback.
- Trade paperback — about 8 to 9 × 5 to 6. The larger, better-made paperback most contemporary fiction and non-fiction appears in.
- Standard hardback — about 9.25 × 6.125, sometimes a little larger.
- Large hardback and reference — around 10 × 7.
- Oversize, coffee-table and deluxe editions — 11 to 14 inches tall and sometimes as wide, occasionally square.
The first four fit an ordinary shelf. The fifth is why people end up stacking books flat on the floor.
Shelf depth and height
A standard bookshelf is around 10 to 12 inches deep and has 11 to 12 inches of clear height between shelves. That takes everything up to a large hardback comfortably, standing upright, with room to get a hand in above the books to lift them out.
An oversize art or photography book at 13 inches tall will not stand on that shelf. It needs either a shelf with adjustable height, or the bottom shelf of a unit where the clearance is often greater, or to be stored flat.
Depth is the measurement people forget. A book 10 inches wide on a 10-inch shelf sits flush with the front edge and will be knocked off; anything deeper than the shelf overhangs and gets damaged along the fore-edge.
Measuring before you buy
Two numbers, taken with a tape measure, prevent almost all of this:
- Clear height between shelves — from the top surface of one shelf to the underside of the next. Not the shelf spacing quoted by the maker, which usually ignores the thickness of the shelf.
- Usable depth — front to back, allowing for a back panel or a wall batten.
Every book on this site has its format stated where the publisher supplies it, and oversize editions say oversize in the title for exactly this reason.
Storage boxes and what they take
The same arithmetic applies to boxes. A box quoted as 13 × 9 × 9 externally has internal dimensions perhaps half an inch smaller in each direction, and that half inch decides whether a row of hardbacks stands upright or has to go in at an angle.
Our storage listings give internal dimensions where the manufacturer states them. Compare against the tallest book you intend to store, not the average one.
A practical guide to capacity: a medium box roughly 12 inches on a side holds around twenty trade paperbacks or a dozen standard hardbacks standing upright. Beyond about thirty pounds, a full box is genuinely difficult to carry.
Storing oversize books properly
Large-format books should be stored flat, not upright. Their own weight is enough to pull a heavy text block away from the spine when they stand on end, and the wider the book the worse the leverage.
Stack them largest at the bottom, no more than three or four high, and do not put anything else on top of them. A flat stack of oversize books makes a perfectly good low table, and every book placed on it is one more load on the one at the bottom.
If they must stand, support them on both sides so they cannot lean at all.
Mixed shelves
Sorting a shelf by height rather than by subject is unfashionable and works considerably better. Books of similar height support each other properly, nothing leans into a gap, and the shelf can be set to the height the books actually need.
If sorting by subject matters more, at least use bookends within each section so a short paperback next to a tall hardback has something to lean on other than the hardback.
The one that never fits
Square-format books — many photography and design titles — defeat most shelves because their width equals their height. Assume they are going on the bottom shelf, in a cupboard, or flat.
What we stock
The books page states the format of every title, including the oversize editions. Rigid boxes and cases with internal dimensions are on the book storage and cases page, and if the shelf needs something on it that is not a book, the display pieces are under decorative book decor.
Measure first, order second — it is the whole of the advice on this page.
