This True-A6 rings planner uses a common ISO A6 (148x105mm) paper size. A6 is an ISO 216 paper size. However, most of the A6 binders or inserts listed on Amazon are actually Personal size binders or inserts. 2. Both A6 and Personal binders have 6 rings, which are spaced into two groups of 3 rings. To determine the correct size, measure the gap between the two groups of 3 rings. A6 Rings planners have a gap of 1.5 inches (38mm). Personal Rings planners have a gap of 2 inches (51mm). So, begin by measuring the distance between the two groups of rings/holes.
