Attention to a New Body Part
The 'stoma' is near your waistline, and that defines your belt position on its ostomy device barrier. The barrier connects the pouch to your body, and its dimensions change with brand, so proof comes from trying.
Aim for longest time between barrier changes with no leaks; e.g. you may be blessed if shower is more often than barrier change.
A few brands I've tried and show here: Hollister, Coloplast & ConvaTec.

Distance between pouch and stoma-cut-out affect how barrier fits your body & belt. These pictures show n millimeters (mm) to remember.
Note this n is not the cut-out for stoma, but it does affect pouch usability.

With your Pre-Cut size established, confirm the barrier does a good job if anything else changes.
That Pre-Cut figure is for stoma only. All other dimensions relate to fitting your body. Different versions, even by same manufacturer, require leak and body-fit testing before placing an order.
Photos are not to scale, these are intended as 1-inch (25mm) Pre-Cut but some may not be. Different brands and styles have unique flange OD and barrier contact area.
