Stitching Wire Specs.
How Many Spools Will I Need?
 |
A staple for a book is usually one inch. Two staples are usually used in each book. (You will need to know the number of staples per book and the number of books for the job being quoted.) (2 inches per book) x (amount of books) = total inches of wire (total inches of wire) / (inches per spool) = amount of spools (total inches of wire) / (inches per pound) = amount of pounds |
