Choosing the proper tape width

The curtain slide tape is only needed on the top portion of the curtain rod where the curtain rings come in contact with the rod. You can measure the circumference of the curtain rod by wrapping a string around the rod and then measuring the string length.

1/2 inch wide tape - This tape width should be used for all curtain rods with a circumference smaller than 2 inches.

3/4 inch wide tape - Curtain rods with a circumference greater than 2 inches should use 3/4 inch wide tape
