Catheters are measured on the French 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, there are different lengths of catheters, including male, female, and pediatric. Male length catheters are usually 16 inches in length. Female length catheters range from 6-8 inches in length. There are some instances where females prefer to use male-length catheters. Pediatric length catheters typically range from 6-12 inches in length. Women and children generally use shorter lengths because of their shorter urethra.
You and your health care professional can determine together what size and length of your catheter may suit your individual needs best.
