How to Measure Coiled Handset Cords


Chances are that you have never wondered how long the handset cord on your home telephone is--until you need to replace it. Manufacturers measure coiled handset cords at their true uncoiled length before coiling them. This makes it easy for them--and difficult for the average consumer--to measure. Follow these simple instructions to measure your handset cord and make shopping for a replacement simple.

Things You'll Need

  • Stiff cardboard
  • Utility knife
  • Ruler
  • Glue
  • Cut the stiff cardboard into two 6-inch by 6-inch squares.

  • Glue the two pieces together using standard hobby glue. This gives the pieces the added strength needed for measuring longer coiled cords.

  • Disconnect the handset cord from the telephone receiver and body.

  • Wrap the cord around the cardboard square starting at one end, uncoiling the cord as you go. Keep the cord tightly wrapped around the cardboard so the cord does not coil back up. Each revolution of the cord around the cardboard square represents 12 inches in length.

  • Count the number of revolutions it takes to wrap the entire cord around the cardboard square. Multiply this number by 12 inches to calculate the true length of the coiled cord.

  • Unwrap the cord from the cardboard square and allow it to recoil. Do not worry if it does not recoil immediately, as it may take some time to return to its original coiled shape.
