| Measuring your binder:
Measure along the straight edge of the ring, as indicated by the red arrow. Do not include any of the curved part of the ring.
Capacities are in 1/4" to 1/2" increments, ande may be as much as 1/8" variation, depending upon manufacturer. For number of sheets per capacity, see chart below.
|
Note: Generally D-ring binders will hold 25% more capacity
than
O-ring/Round Ring binders.

*For tabs, deduct 4 sheets per tab from above totals.For example: 5 tabs = 20 sheets, which would be deducted from the above total number of sheets.
For larger binders, you can approximate the number of sheets by calculating from the totals above. For example, a 2" binder can hold up to 500 sheets of 24# bond, and a 1" binder can hold 250 sheets. Therefore, a 3" binder would be needed to hold up to 750 sheets.
