The live roll cross-section makes OD, core, and wound stock relationships clear while exact numeric fields keep entry precise.
MEASURE THE ROLL · PLAN THE RUN
Know what’s left without unwinding it.
Turn outside diameter, core OD, and total media thickness into an estimated web length and maximum label count—right at the press, warehouse, or packing bench.

An instrument, not a generic calculator.
Label-specific estimates
Enter label length and gap. RollLength derives pitch, floors the theoretical maximum, and deducts your optional production reserve.
Reverse-solve the roll
Start from required web length or usable labels and calculate the outside diameter you should expect.

Planning estimates assume uniform thickness and winding. Verify critical production runs physically. Maximum-OD checks compare diameter only and do not verify overall printer compatibility.
