Learn More About French Catheters: Sizing & Fit Customized to You

From pediatric lengths to adult women and men, catheters come in a variety of sizes. Ultimately your doctor will determine the proper french catheter size for you, taking into a variety of factors. Size is measured by the tube’s external diameter, also called the french size. The higher the diameter, the larger the french size. This number is calculated by multiplying the diameter length in millimeters by 3 units. As an example, a catheter with a 4.7 mm diameter’s french size will be FR 14.

The Importance of Determinding The Correct French Catheter Size

Finding the correct french catheter size is crucial to the self-catheterization process for numerous reasons:

  • If your french catheter size is too small, it will take much longer to empty the bladder.
  • If your french catheter is too large, inserting the catheter will be a painful process.
  • French sizes too large for the urethra will introduce pain during catheter insertion.
  • French sizes too small for the urethra will directly cause leakage during the self-catheterization process.
