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.

Catheter Selection - Size • The internal diameter of a catheter is measured in Charriere (Ch) – one Ch equals 1/3 mm, therefore 12 Ch equals 4 mm. • Catheter sizes for men are between 12Ch & 16Ch. • The smallest size should be chosen to provide adequate drainage. • Larger sizes can cause irritation & bypassing of

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.

Most physicians use a French 14-gauge, or 0.184 inches (about 4.7 mm), for adult males and a French 12- to 16-gauge, or 0.158 to 0.21 inches (about 4 to 5.3 mm), for adult females.

10CH = 3.3mm diameter. 12CH = 4mm diameter. As you can see, the difference in sizes are very small - sometimes only 0.6 millimetres.
