Binding position refers to the edge of the document which is bound together (for example, where the spine, wire, comb etc. is placed).

The binding options depend on the orientation of your document.
​
For a portrait document, the 'left long edge' or 'top short edge' can be bound.

For a landscape document, the 'left short edge' or 'top long edge' can be bound.

These configurations are designed for left to right reading. If your document is for right to left reading, please contact us to request that your binding edge is changed to reflect this.
