These 9.5mm A4 black wiro binding rings are 3:1 ratio cut pieces designed to hold up to 80 sheets of standard 80 gsm paper.

How to Measure Wiro Binding Rings

Wiro binding rings are measured by diameter across the loop at its widest point. A 9.5 mm ring holds approximately 80 sheets of 80 gsm paper. Always match the pitch ratio (3:1) to your binding machine for proper alignment. For best results, choose a ring diameter that leaves 3-5 mm of extra space beyond your paper stack thickness.
