Keeping this in view, is a 16 French Foley bigger? A catheter with a diameter of 4.7 mm will have an FR size of 14. The common Foley catheter sizes are in the range of 10 FR to 28 FR. A 16 French Foley catheter indicates a Foley catheter size and means an indwelling catheter with an FR size of 16.
How is the size of a Foleys catheter determined?
All internal catheters, including Foleys and intermittent styles, are sized by a universal gauge system which is referred to as a “French size.” This is based upon the measure of the external diameter of the tube. The way the size is determined is a simple multiplication of 3 (diameters in millimeters multiplied by 3 = the French size).
Is a 14 French catheter the same as a 16 catheter?
A catheter with a diameter of 4.7 mm will have an FR size of 14. A 16 French Foley catheter indicates a Foley catheter size and means an indwelling catheter with an FR size of 16. Click to see full answer. Considering this, is a 14 French catheter smaller?
Why is determining the French size such an important part?
Why is determining the French size such an important part of selecting the right catheter for your needs? Efficiency and comfort are both important elements in the self-catheterization process. If you use a urinary catheter with too large of a diameter for your urethra, insertion can feel difficult or cause friction.

What is the biggest size foley catheter?
Foley Catheter Sizes In general, urinary catheters range in size from 8Fr to 36Fr in diameter. 1 Fr is equivalent to 0.33 mm = . 013" = 1/77" in diameter. The crosssectional diameter of a urinary catheter is equal to three times the diameter.

How do I choose the right size catheter?
To determine the size of a urinary catheter, simply multiply the diameter length in millimeters by 3. For example, if the catheter has a diameter of 4.7 mm, it will have an FR size of 14. Most catheters with funnels utilize a universal-coding system to determine the sizing.
What are the different sizes of catheter?
The three main catheter lengths to know are:Male length catheters (typically 16 inches)Female length catheters (most often 6 to 8 inches)Pediatric length catheters (10 inches)
What size catheter is typically used for adults?

What determines catheter balloon size?
Each catheter is sized by the outer circumference and according to a metric scale known as the French (Fr) gauge (range is 6 to 18 Fr), in which each French unit equals 0.33 mm in diameter. The golden rule is to use the smallest catheter size (termed bore), generally 14 to 16 Fr, that allows for adequate drainage.
