Estimate a finished roll’s outside diameter, or work backwards from a maximum diameter to find how many labels will fit.

Set this to 0 if adhesive is already included in your label-material figure.

Important: this is a production guide, not a guarantee. Roll tension, compression, material tolerances and winding conditions affect the finished diameter. Small labels can wind more tightly because gaps form a larger proportion of the repeat.

In reverse mode the result is rounded down to a complete repeat, so it does not intentionally exceed the chosen maximum diameter.
