Options and example settings
Calculation method
theoretical_labels = floor(pi*positive(outer_diameter_mm^2-core_diameter_mm^2)/(4*liner_total_thickness_mm*label_pitch_mm)) (^ means exponentiation; trig functions ending in d use degrees).

Trim, bleed and safe margins are different boundaries. Check page ordering against the printer’s duplex and binding convention. Packaging footprints are estimates rather than production-ready certified dielines.
Limitations and common mistakes
- Ideal tightly wound uniform thickness; gaps and winding tension excluded. Nominal print or packaging geometry with explicit units. Confirm press, stock, binding and production tolerances with the actual supplier.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
