What is the diameter of a roll label spool?

A roll label spool is described by two diameters: the inner core, which is the tube the labels wind around, and the outer diameter, which is the finished size of the full roll. Both affect whether a roll fits your dispenser.

• Standard inner core: 3 inch diameter, our default
• Smaller inner core: 1 inch available upon request
• Outer diameter: up to about 6 inches on a standard roll
• The exact outer diameter depends on label size and quantity per roll
