DISCLAIMER: The column “sheets of paper” is a general guideline only. Paper can vary in thickness depending on the type and grade.
For an accurate estimate, the publication should be measured with the gauges available.

HELPFUL HINT:

FOR BEST RESULTS WHEN BINDING:
• Do not use a length of binding that is longer than the binding edge of the sheet
• For accurate sizing, measure the actual thickness of the document you are binding, including
covers, then add as listed below:
• For correct coil diameter, add 3 mm
• For correct wire diameter, add 1/8"
• For correct comb diameter, add 1/8".
