Results
- Labels per roll
- 4,587 labels
- Web length
- 472.5 m
Formula
Length = π × (OD² − core²) ÷ (4 × thickness)
Labels = ⌊Length ÷ (label + gap)⌋ × across
Assumptions & limits
- Tight, uniform winding. Typical self-adhesive paper label + glassine liner ≈ 130–150 µm.
Worked example
π × (300² − 76²) ÷ (4 × 0.14) = 472,500 mm = 472.5 m ÷ 103 mm → 4,587 labels.
