Choosing the correct stoma opening size is essential to ensure a secure, comfortable fit and optimal protection against leakage. The best stoma opening size is one that matches your stoma’s diameter—too large, and you risk leaks; too small, and you may cause irritation. Stoma caps typically offer a range of cut-to-fit or pre-cut sizes. For example, the Coloplast 2803 Assura Stoma Cap accommodates stomas from 1/2" to 2", while the Coloplast 2802 Assura Stoma Cap fits 1/2" to 1-3/4". This variety allows users to select a size that offers both security and comfort.
