How It Works
The calculator uses the Archimedean spiral formula to determine the length of paper wound on a roll:
L = π × n × (D + d) / 2
Where: L = length, n = number of wraps, D = outer diameter, d = core diameter
Linerless vs Traditional: More Length Per Roll
📜
Traditional Labels
Includes backing liner that takes up ~40% of roll thickness
🎯
Linerless Labels
No backing waste = ~40% more labels per roll
