The "width" of spiral binding typically refers to the diameter of the spiral coil or ring, which determines the number of pages a document can hold. This diameter is not a single fixed measurement but varies significantly depending on the thickness of the paper being bound.
According to the provided reference for Classik spiral rings, the available sizes (diameters) are designed to accommodate different paper thicknesses, binding documents from as few as 50 pages up to 480 pages.
Spiral Binding Diameter Sizes
The reference specifically lists the following diameters for Classik spiral rings:
- 8mm
- 10mm
- 12mm
- 15mm
- 20mm
- 22mm
- 25mm
- 28mm
- 30mm
- 32mm
- 35mm
- 38mm
- 40mm
- 42mm
- 45mm
- 48mm
- 52mm
These various diameters allow for binding documents of different thicknesses, ensuring that the spiral coil is appropriately sized for the number of pages. A smaller diameter is used for fewer pages, while a larger diameter is needed for thicker documents.
Diameter and Page Capacity
The choice of spiral binding diameter is directly related to the maximum number of pages (or the total thickness of the document) it can bind. While the reference links the full range of sizes (8mm-52mm) to the full range of pages (50-480), typically, smaller diameters are for fewer pages and larger diameters for more pages.
Here's a simplified example based on the reference's information that these sizes bind documents from 50 to 480 pages:
| Spiral Diameter | Approximate Page Capacity (based on standard paper) |
|---|---|
| 8mm | Around 50 pages |
| 10mm | Around 70 pages |
| ... | ... |
| 25mm | Around 220 pages |
| ... | ... |
| 52mm | Around 480 pages |
Note: Page capacity can vary slightly depending on the paper's weight and thickness.
Choosing the correct diameter is essential for a functional and aesthetically pleasing binding. If the diameter is too small, the pages will be compressed, making turning difficult. If it is too large, the pages will sag within the coil.
In summary, the "width" of spiral binding refers to the diameter of the coil, and this size varies across a range, such as the 8mm to 52mm sizes mentioned in the reference, to accommodate documents of different page counts or thicknesses.
