An odd number of blades, such as a five-blade fan, requires a center point to make an accurate measurement to determine the diameter of the blades for proper replacement.

Things You Will Need

  • Measuring tape
  • Poster board
  • Freezer tape
  • Marker
  1. Turn the ceiling fan off and wait for it to quit turning.

  2. Measure the ceiling fan from the tip end of one blade to the tip end of the blade directly across from it, using a measuring tape. This is the diameter of the fan area and the size of the fan blade.

  3. Measure a five-blade ceiling fan from the tip on one blade to the center of the fan. Double this measurement to obtain the fan blade size. A five-blade fan does not have blades directly across from each other as a four-blade ceiling fan does.

The Drip Cap

  • Measuring ceiling fan blades to replace them in their brackets includes the size of the fan blades from tip to tip when fully assembled.
