Size 12 Fr is large enough to relieve urinary obstruction in most adults, although practitioners typically choose size 14 to 16 Fr for initial catheterization. Larger diameter catheters may be required for adequate drainage of hematuria or clots.
What does FR size mean?

What is the average catheter size for males?
The average catheter size used by adult men is between 14FR to 16FR. Most men use 14FR catheters. The average catheter size used by adult women ranges from 10FR to 12FR.
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.
Which catheter size is bigger?
Male length catheters are usually 16 inches in length. Female length catheters range from 6-8 inches in length. Pediatric length catheters typically range from 6-12 inches in length.
Why are catheters sized in French?

What are Urinary Catheters?
Urinary catheters are thin, flexible tubes that are inserted into the urethra to empty out the bladder. They are used by people who are unable to drain out the urinary bladder on their own either because of a surgery, urinary incontinence and enlarged prostrate or other medical reasons.
Sizes of Urinary Catheters
The size of a catheter is calculated in FR – that is French scale or French gauge system. It was devised by a 19th-century Frenchman named Joseph-Frédéric-Benoît Charrière, a maker of surgical instruments.
Length of Catheter
Other than the Urinary Catheters size, the length of the tube is also important. This also should be determined by your doctor. He will base his decision about catheter length on the patient’s body type and the procedure meant to be carried out.
How to determine Catheter Size?
It is important to get the catheter sizing right. The reason is three-fold. If the FR is smaller than what is needed, then the emptying out of the bladder will take time. If the FR is too big for the urethra, then there will be difficulty and pain when inserting the catheter.

How to tell the French size?
The French size is three times the diameter in millimeters. Thus, the French size is roughly equivalent to the circumference of a circular catheter; the true circumference being slightly larger (circumference = diameter * π where π is approximately 3.14).
What is the French size of a catheter?
The French size is a measure of the outer diameter of a catheter (not internal drainage channel, or inner diameter ). So, for example, if a two-way catheter of 20 Fr is compared to a 20 Fr three-way catheter, they both have the same external diameter but the two-way catheter will have a larger drainage channel than the three-way.
What is the French scale used for?
Unsourced material may be challenged and removed. The French scale or French gauge system is commonly used to measure the size of a catheter. It is most often abbreviated as Fr, but can often be seen abbreviated as Fg, FR or F. It may also be abbreviated as CH or Ch (for Charrière, its inventor). However, simply gauge, G or GA generally refers ...
