## What is RollLength?

Know what is left on a label roll without unwinding it.

RollLength is a purpose-built label stock workbench for printers, converters, packaging teams, warehouses, and small product businesses. Enter the roll outside diameter, core outside diameter, and total media thickness to estimate remaining web length.

LABEL-SPECIFIC RESULTS
• Estimate remaining web length
• Add label length and gap to derive pitch
• See estimated maximum and usable label counts
• Deduct an optional production reserve for leader, damaged wraps, splices, or waste

PLAN THE NEXT ROLL
• Reverse-solve required outside diameter from a target web length
• Plan from a target usable label quantity
• Apply the same reserve policy in both directions
• Compare the result with a saved maximum outside diameter

BUILT FOR THE WORKBENCH
• Live roll cross-section and unspooled label web
• Exact millimetre and inch entry
• Saved roll production tickets
• Share concise estimates
• iPhone and true two-column iPad layouts
• VoiceOver, Dynamic Type, and Reduce Motion support

ROLLLENGTH PRO — ONE LIFETIME PURCHASE
• Unlimited saved roll tickets
• Reusable material and maximum-OD presets
• Professional PDF report export
• No subscription

PRIVATE BY DESIGN
RollLength works offline. It has no account, ads, analytics, tracking, or collected personal data. Saved records stay on your device.

IMPORTANT
Results are planning estimates based on uniform thickness and winding. Verify critical production runs physically. A maximum-OD check compares diameter only; it does not verify media width, core adapters, winding direction, sensors, feed path, or overall printer compatibility.
