How
to consider the format of a binder?
The size of the binder depends on the size of the
paper sheet it needs to hold. An A4 sheet (210x297) with hole punching on the 297 side is a standard A4 size sheet. However, the binder to hold these sheets would be described as a 297x210 sheet size binder. The binding edge is always listed fist.
The other thing to consider is whether or not index tabs will be used in the binder. If so you need to make sure the binder case incorporates an index tab allowance so the tabs don't stick out beyond the edge of the binder case.
Many binder cases will have an allowance for a 13-15mm index tab extension. Each binder case has a different outside dimension depending on the binder case material, ring size and style.
Lever Arch and Post binders use metal posts instead of rings. These are primarily used to hold extra large capacity materials such as catalogs. Fixed posts are 30mm to 100mm and expandable metals are up to 130mm.
Boosters are the triggers that open and/or close the binder rings and are standard unless otherwise specified.
