Choosing the Right Pitch: 2:1 vs. 3:1 Spools
When selecting double loop wire spools, the “pitch” refers to the number of holes per inch. Choosing the correct pitch is determined by the thickness of your document and the punching pattern of your binding machine.
3:1 Pitch (3 Holes Per Inch)
This is the most common pitch for professional office documents, presentations, and smaller booklets.
Best For: Thin to medium-thickness documents.
Capacity: Typically holds between 30 and 120 sheets of standard 20 lb paper.
Look: The holes are closer together, providing a refined, elegant appearance for smaller projects.
Compatibility: Must be used with a 3:1 pitch punching machine.
2:1 Pitch (2 Holes Per Inch)
This pitch is designed for versatility and is the industry standard for high-capacity binding.
Best For: Medium to very thick books, manuals, and large catalogs.
Capacity: Accommodates a wider range, from 30 up to 220 sheets of standard 20 lb paper.
Look: The loops are spaced further apart, which provides the structural integrity needed to support heavier, thicker documents.
Compatibility: Must be used with a 2:1 pitch punching machine.

Technical Guide: Selecting the Correct Wire Diameter
Choosing the right size for your 2:1 double loop wire spools is just as important as choosing the pitch. To ensure a professional finish where pages turn freely, you must account for the total thickness of your document, including the front and back covers.
How to Measure for 2:1 Double Loop Wire Spools
Measure the Thickness: Lay your document (including covers) flat on a table and measure the total height.
Add the “Wiggle Room”: To allow pages to turn 360°, add 1/8″ (approx. 3mm) to your measurement.
Match the Spool Size: Choose the spool diameter that most closely matches your final total.
