How are irregular stomas measured?

• A. Measure width and height separately
• B. Measure only the widest point
• C. Use only a pre-cut measuring card
• D. Measure circumference

Answer: (A)

Irregular stomas need two-dimensional sizing, so you measure width and height separately to capture the stoma’s actual footprint. This approach creates an opening that follows the stoma’s contour in both directions, giving a snug fit and reducing leaks and skin irritation. Measuring only the widest point misses other dimensions and can produce an opening that is too large in some areas or too small in others. Relying on a pre-cut measuring card won’t always match irregular shapes, since those cards assume standard forms. Measuring circumference alone also falls short because it can’t describe the non-circular outline of an irregular stoma.
