What Binder Sizes Are Available?
The largest mechanism, on the far left hand side of the picture, has a 10cm capacity, the smallest on the right has a 2.5cm capacity. To put this in more meaningful context, the lever arch mechanism in the middle (which is a standard lever arch mechanism) has a 4.5mm capacity.
What Do You Mean By Capacity?
How much the binder can take measured in centimetres. The size of the binder (e.g. 4cm) doesn't refer to the physical height of the mechanism but the height of the vertical length of the binder before it starts to curve round at the top.
We refer to each mechanism by size and type, for example a '4cm D Ring Binder'. This gives you an idea, when ordering, which size binder mechanism you need depending upon the volume being put in the binder.
How Do I Know What Size Binder I Will Need?
The size of binder that you require depends on the height of the stack of pages that you are going to put into it. If you are using page protectors, you also need to take account of the number of pages in each one and the weight of paper you are using.
As an approximation the 6.5cm mechanism will hold comfortably around 100 page protectors if using standard 80gsm paper.
If you can stack the pages and measure them, this is the best way to decide on the binder that you need.
