The three main book binding methods are saddle stitching, perfect binding and PUR binding. Saddle stitching uses wire staples for thin booklets. Perfect binding glues pages to a flat spine for magazines and catalogues. PUR binding uses a stronger, more flexible adhesive for thicker or long-life publications. Your page count and budget decide which fits.
Choosing how to bind a booklet, brochure or book feels like a small detail next to the design. It is not. The binding decides how the finished piece opens, how long it lasts and how much it costs to produce. Pick the wrong method and pages fall out or the spine cracks on the first read. This guide explains the three most common book binding methods and when to choose each one.
What is book binding?
Book binding is the process of joining printed pages and a cover into a single, finished publication. It holds the pages in order and protects them through handling and storage. Monks were binding manuscripts as early as the sixth century. After the printing press arrived, new machinery in the mid-nineteenth century opened binding up to mass production.
Today most commercial work uses one of three methods: saddle stitching, perfect binding or PUR binding. Each suits a different page count, budget and lifespan.
What is saddle stitching?
Saddle stitching is the simplest and most affordable binding method. Folded sections are gathered, dropped over a moving saddle at the spine, and secured with two wire staples through the fold. The result is a flat booklet that opens fully and lies flat on a desk.
It suits low page counts, usually 8 to 64 pages, and works best in multiples of four. Think event programmes, short brochures, newsletters and price lists. It is quick to produce and keeps costs down, the standard choice for short-run and high-volume booklets. The limit is thickness. Beyond around 64 pages the staples struggle and the booklet will not sit flat.
What is perfect binding?
Perfect binding glues the pages and cover together at the spine to create a flat, square edge, like a paperback book or a thick magazine. The folded sections are gathered, the spine edge is ground off, and adhesive bonds the pages to a wraparound cover. The flat spine gives you a printable edge, which is useful for catalogues and directories that sit on a shelf.
Standard perfect binding uses a hot melt EVA adhesive, short for ethylene vinyl acetate. It holds well and keeps costs sensible. It suits page counts from around 40 up to several hundred, the go-to for magazines, annual reports, catalogues and softback books where a clean spine matters.
What is PUR binding?
PUR binding looks like perfect binding but uses a different glue. Instead of EVA, it uses a polyurethane reactive (PUR) adhesive applied in a thin layer along the spine before the cover is folded over. PUR cures by reacting with moisture in the air, forming a bond far stronger and more flexible than EVA.
The payoff is durability. PUR pages resist pulling out, cope with heat and cold without cracking, and let the book open flatter. This makes PUR right for thicker publications, heavy-use books, and coated or laminated stock that standard glue struggles to grip. It costs more than standard perfect binding, but the finish and lifespan justify it.
How do you choose the right binding?
Three things decide the method: page count, durability and budget. For thin booklets up to around 64 pages, saddle stitching is fastest and cheapest. For thicker documents that need a flat, printable spine, perfect binding gives a professional paperback look at a sensible price. Where the publication is thick, heavily handled, printed on coated stock, or expected to last, PUR binding is worth the extra cost for its strength and lay-flat opening.

Frequently asked questions
What is the difference between perfect binding and PUR binding?
Both glue pages to a flat spine and look similar. The difference is the adhesive. Perfect binding uses EVA glue, which is cheaper. PUR binding uses polyurethane reactive glue, which is stronger, more flexible, copes better with coated stock and lets the book lie flatter. PUR lasts longer.
How many pages will saddle stitching hold?
Saddle stitching works for roughly 8 to 64 pages, in multiples of four. Below that there is too little to staple, and above it the wire staples will not hold the bulk and the booklet stops lying flat. For higher page counts, choose perfect or PUR binding instead.
Which book binding lies the flattest?
PUR binding opens the flattest of the glued methods because its adhesive stays flexible. Saddle-stitched booklets also open flat, as they are stapled through the fold. Standard perfect binding is the stiffest and springs shut more, so avoid it where readers need the book to stay open on a surface.
Which book binding is the cheapest?
Saddle stitching is the cheapest binding method for low page counts, as it uses only wire staples and minimal handling. Perfect binding costs more but suits thicker documents. PUR binding is the most expensive of the three, reflecting its stronger adhesive and longer lifespan.
What paper works best for PUR binding?
PUR binding grips coated, laminated and silk stocks that standard EVA glue struggles to hold, so it is the safer choice for premium, coated publications. For lightweight uncoated text stock, standard perfect binding is usually enough.
