I need to bind 275 sheets of 28# paper plus 90# cover, what size 4:1 pitch coil do I need? thank you
Asked by Oly
Thank you for your question. All of the scales we have for page count are based on 20# paper which is thinner than 28# paper but our sizing guide ( found here ) on the coil table there is a scale for overall document thickness. All you would need to do is measure the thickness of the finished document and refer to the coil table to be sure you get the right size.
