What's your definition of a "regular size diaper"?? Most of the on-line adult diaper vendors use sizes like "Small, Medium, Large". But then if you click on each brand that they sell, it usually lists the "Inches" range for that size. For example, NorthShore sells BetterDry diapers... The medium says 29" to 43". But their MegaMax diaper says medium is a 32" to 44". So you should check the actual "inch size" of any brand you're looking at, rather than just go by a "Small, Medium, Large" label.
Also, sometimes an inch size rating may not be the best for you. For example, I have a 36" waist, so looking at the labels, a medium size of most brands should fit me. However, I've found that a large size diaper in some brands fit me better, it wraps around to the front more, has wider "wings" for more absorbency, and a higher rise on my waist, to prevent leaks at night. Of course, a larger size also makes a larger "Diaper Bulge" in my slacks, so it depends on your clothing choices and how discreet you want to be.
