Flange size is a key consideration because it must match your stoma size and the corresponding barrier for a secure and comfortable fit. The best flange size is one that ensures a tight seal without causing irritation. Commonly available flange sizes for high output pouches include 45 mm (1 3/4") and 70 mm (2 3/4"), providing options for both smaller and larger stomas. For example, the Convatec 420695 (45 mm) is ideal for smaller stomas, while the Convatec 420697 (70 mm) accommodates larger sizes. Having a range of flange sizes ensures you can select a pouch that fits your body comfortably and securely.
