When ordering labels on a roll, core size matters.
It determines whether the roll fits your printer.
Core sizes:
– 25mm (1″) — Desktop printers (Zebra GK/GC)
– 38mm (1.5″) — Retail & dispatch
– 76mm (3″) — Industrial printers (Zebra ZT Series, Sato, Toshiba)
How to check:
Look inside your printer or search your model online.
Request samples or ask us to confirm core size.
