1. Measure waist, add 14 inches to your waist size, and divide the total by 2. This will give you a minimum width size.
Example: If a person has a 39 inch waist enter the following calculation:
39 + 14 = 53
53 / 2 = 26.5
You would need to select a minimum of a 27 inch width diaper.
2. Measure through the crotch BELT TO BELT, add a minimum of 3 inches, and round up to our nearest diaper length.
Example: If a person has 29 inch measurement belt to belt through the crotch enter the following calculation:
29 + 3 = 32
You would need to select a minimum of a 32 inch long diaper.
In this example the minimum size diaper would be our medium which is a 34"X26". The small would be not be large enough.
3. Consider if extra absorbency is needed. If so, larger diaper may be required. The larger the diaper the more cotton flannel, thus more absorbency provided.
