Intermittent catheters are measured on the French or Charriere scale that is based on the external diameter of the tube. This is commonly abbreviated as FR or CH and will be listed on your catheter package.
Intermittent catheters with funnels typically use a universal color-coding system to help determine what French size a catheter is. The funnel color corresponds to its French size. For example, this green funnel indicates this is a 14FR catheter.
In addition to different French sizes (diameter sizes), there are also different lengths of catheters:
There are some instances where females prefer to use male-length catheters. Women and children generally use shorter lengths because of their shorter urethra. You and your healthcare professional can determine together what size and length catheter may best suit your individual needs. Your doctor should take into consideration your preferences as well as your particular anatomy.
