Pitch is the number of binding holes per inch. A 2:1 punch makes two per inch and a 3:1 punch makes three. The two patterns are not interchangeable.
| Pitch | Pattern | Typical use |
|---|---|---|
| 3:1 | Tighter, about 34 holes along an A4 edge | Thinner notebooks and planners, smaller diameters |
| 2:1 | Wider, about 23 holes along an A4 edge | Thicker reports and manuals, larger diameters |
Wire diameter and page capacity are separate choices, based on the finished book thickness. See the size and capacity chart.
Valenna supplies replacement covers unpunched by default. Request 2:1 or 3:1 punching in Notes. Rebinding needs a suitable new wire, because the old closed wire cannot be reused. See preparing cover holes and binding.
No. The hole spacing and loop count differ.
