Can someone quickly tell me the length of paper and film for 220?   I’m slitting 70mm to 120/220 width in bulk.  I hope to roll 220 from this film but all work needs to be done in a large changing bag.  I have everything I need except an exposed roll of 220 to get the measurements from.  Since I’m working in a changing bag I have to estimate length of film so inches would best for me.  
Thank you.
