A catheter size that is too large may result in mucosal irritation and localized trauma. A catheter size that is smaller than the urethra will result in leakage.
What does FR mean in size?
FR or FG (short for 'French Gauge') refers to the diameter or thickness of the tubes. Every 0.33 millimeter (mm) of thickness /diameter, measured on outer walls contributes 1 FR.

How big is a male catheter?
Male Catheter Lengths The male anatomy typically has a longer urethra than the female anatomy. That's why male catheters (sometimes known as unisex catheters) are usually around 16 inches long on average.
What are the 4 types of catheters?
Indwelling catheters (urethral or suprapubic catheters) An indwelling catheter is a catheter that sits in the bladder. ... External catheters (condom catheters) A condom catheter is a catheter placed outside the body. ... Short-term catheters (intermittent catheters)
What are the 3 main types of catheters?
There are 3 main types of catheters:Indwelling catheter.Condom catheter.Intermittent self-catheter.
How do you choose a catheter size?
Catheter length for men and womenStandard catheter length male: 16 inches; average length of male urethra: 20 cm.Standard catheter length female: 5-6 inches; average length of female urethra: 4 cm.
What is the French scale?
Commonly referred to as simply “French size,” the French Scale system is how all modern catheters are measured. All urinary catheters are made in French sizes, and these sizes are the same for every brand and manufacturer.
How wide are catheters?
Catheters are just millimeters wide, with different sizes often being just fractions of a millimeter apart. The French Scale takes all those fractions and puts them into a sizing chart that’s much easier to read.
Why is it important to know the size of a catheter?
Proper catheter sizing is an essential part of successful urinary management. If the catheter is too small, then urine will pass too slowly. If the catheter is too big, it could cause pain or even damage the urethra. That’s why only a doctor can determine the catheter size you need.
Can you change the size of a catheter?
That’s why only a doctor can determine the catheter size you need. The catheter size is part of the prescription and cannot be changed unless a doctor provides a new prescription with a different size.
What is the average French size?
The average or most common French size tends to be around 14 to 18 French for most male catheter-users. We have male length catheters available in all types and sizes from all the available brands on the market, including male pocket catheters. Take a look at a few popular catheters below from our online showcase.
Why is determining the French size of a catheter important?
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. Catheterization may even feel painful if you’re using a catheter that’s too big. Also, if it’s far too large, you will not be able to insert it at all.
What is the gauge system for Foley catheters?
All internal urinary catheters, including Foley catheters and intermittent catheters, are sized by a universal gauge system. This gauge system is known as a French size, which is based upon a measurement of the external diameter of the catheter tube.
How to find the French size of a catheter?
The French size of a catheter is determined by a simple multiplication of 3 (diameters in millimeters multiplied by 3 = the French size). For example, if a catheter has a diameter of 4.7 millimeters, then the French (Fr) size is 14.
Can you use a catheter that is too big?
Catheterization may even feel painful if you’re using a catheter that’s too big. Also, if it’s far too large, you will not be able to insert it at all. On the other hand, if you use a French size that is too small, you may find the pace of urine drainage is very slow.
Can a French size catheter escape urine?
In addition, if you use a catheter French size that’s much smaller than your urethra, urine may escape around the catheter tube. This can be messy, and it’ll be harder to control the flow. Luckily, catheters are made in a vast range of French sizes to suit all kinds of bodies.
What is the size of a French catheter?
1 "French" or "Fr" is equivalent to 0.33 mm = .013" = 1/77" of diameter.
How long is a catheter?
Common lenghts of 6 to 8 inches are used for women while lenghts of 14 or more inches are often used for men.
Do intermittent catheters come in different sizes?
Yes. Anatomical differences and a variety of other factors in body function and medical needs require intermittent catheters to be manufactured and sold in sizes. Intermittent catheters are available in different lengths and sizes suitable for men and women.
Understanding the French scale for intermittent catheters and Foley catheters
Catheter size relates to the thickness or diameter of the catheter and is measured in Charriere (Ch) or French Gauge (FG). French sizes only apply to intermittent and indwelling (Foley) catheters.
Selecting Catheter Size
When selecting a catheter for urinary drainage, the smallest possible diameter should be used that still allows adequate drainage. Using too large of a diameter (or French size) can be associated with increased bladder irritability and trauma.
How do I know the size of my current intermittent or Foley catheter?
Most catheter manufacturers follow a universal system of color-coding to label the catheter size, and they also clearly indicate the catheter size on the external packaging or wrapper.
Why do I need to use the right size of catheter for my individual body type?
In their 2009 Guideline for Prevention of Catheter-Associated Urinary Tract Infections (CAUTI), the Centers for Disease Control (CDC) recommends that unless otherwise clinically indicated, individuals should consider using the smallest diameter catheter possible, that still allows for good urinary drainage, to minimize bladder and urethral trauma.
What is the difference between the French size of a catheter and its length?
While intermittent catheters and Foley catheters have French sizes according to diameter, it is also important to choose a catheter length that is appropriate for your body type and medical needs.

Yes, we are happy to assist you with catheter samples and invite you to request them here.
Why is it important to choose the right size catheter?
Choosing the right sized catheter helps in efficiently managing incontinence and urological conditions. The wrong sized catheter can damage the urethra or bladder and can also be ineffective in managing your condition.
What is the average size of a male catheter?
The average size of a male intermittent or indwelling catheter is between 14FR to 16FR. For adult women, an intermittent or indwelling catheter ranges from 10FR to 12FR. Catheters are also color-coded based on their French sizes.
How many millimeters is a catheter?
Catheter sizes are measured in French units or FR. Technically speaking, one FR is equal to 0.33 millimeters in terms of the diameter of the catheter. The FR size scale is only used for intermittent and indwelling catheters whereas external catheters are directly measured in millimeters.
