Additional Information

 

Nominal Tape Widths vs Actual Widths

Tape rolls are cut to standard tape industry metric widths of approx. 24mm per 1-inch of nominal width ordered. As a result ACTUAL tape widths are normally 5% narrower than the NOMINAL width shown in inches. Examples:

  • 1" Nominal width = 15/16" (24mm) Actual width
  • 2" Nominal width = 1-7/8" (48mm) Actual width
  • 3" Nominal width = 2-13/16" (72mm) Actual width

Note that tape rolls are NOT guaranteed to be splice-free.
