Davey Board vs Chipboard: Which Book Cover Board Holds Up?
Davey board vs chipboard comes down to density, acidity and price: buy Davey for case bindings and chipboard for mock-ups and practice covers.
What to take away
- Davey board is the denser, acid-free choice, usually sold at 80 to 120 points.
- Chipboard is lighter and cheaper, typically 30 to 60 points thick.
- Choose Davey board for case bindings, heavy text blocks and library rebinding.
- Choose chipboard for mock-ups, spine-width tests and practice covers.
- Neither board is a finished cover, and neither one stops a warp by itself.
Board choice shows up in the hand before it shows up in the wear. A case binding made with the wrong board feels floppy at the joint or stiff at the spine, and the fault often gets blamed on the sewing instead.
Board types and what each is made of
Davey board is a US-made binder's board, pressed from recycled fiber to high density. It is sold in pads or sheets, usually 9 x 12 or 12 x 18 inches.
Chipboard, sometimes labeled greyboard, is formed at lower density from similar fiber. The wider paperboard grades are sorted by density and forming method, and chipboard sits at the light end.
Thickness is quoted in points, one point being one thousandth of an inch. Binder's board thickness for a case binding usually lands between 80 and 120 points, or 0.080 to 0.120 inches. Chipboard cut for book covers tends to run 30 to 60 points.
The criteria that decide the choice
Four things separate the boards in practice: stiffness, acidity, price and edge behaviour under a knife. Acidity matters because an acidic board can damage paper over decades, and it drives much of the cost gap. Stiffness decides how the finished book opens.

Board is the least recoverable material in a case binding, so it rewards a slow decision. The guide to choosing recoverable materials ranks each choice by how easily it can be undone.

Those dollar figures are illustrative US retail ranges from art store listings, and they move with pack size and shipping.
Davey board at US suppliers
American suppliers stock Davey board as pads and singles. Price climbs with thickness faster than with sheet size. An 80 point sheet sits near the bottom of the range above.
A 120 point board for oversize books costs more and often ships only in packs. The federal binding spec names it outright: the GPO style manual binding specification treats Davey board as the standard board for government publications.
Chipboard at US suppliers
Chipboard sells in bulk, and that is where the price gap opens. A pack of 12 x 12 sheets often costs about what two Davey sheets cost. Hardware store panels cost less again, though they are not sold as acid-free.
Practice covers are where this board earns its place: a bookbinding beginner kit leans on cheap board for exactly that reason.
Example: a 900 page text block
Take a representative job, not a named book: a 900-page local history with a text block about 2.5 inches thick, trimmed to 6 x 9 inches.

- 2.5 inchestext block thickness
- 6 x 9 inchestrimmed page size
- 100 to 120 pointsDavey board thickness needed
At that weight, 60 point chipboard bows at the joint within a year. The boards want 100 to 120 points of Davey board, grain parallel to the spine.
A chipboard dummy of the same book costs about $1 and settles the spine width first.
Where each board wins
Davey board is right for a heavy text block, for library rebinding, for books that must open flat in twenty years, and for any board that sits directly against paper. Chipboard is right for dummies, spine width tests, single-section pamphlets, and slipcase trials where the covering sits on both faces.
When a warp appears, most people blame the paste. Naming the fault correctly is most of the diagnosis, and the notes on precise vocabulary show how much a change of word narrows the cause.
What neither board solves
Neither board controls moisture. Both take on and give off water with the room, and both curl when paste goes on one side only. Grain direction is a second shared limit: board cut across the spine will fight the text block, whatever the grade.
Storage habits matter as much as grade. Conservation guidance from the NPS conservation notes treats board, cloth and adhesive as one system. Flat board stock kept against a damp wall will warp within a season.
