The rise measurement is from the top front of the cover to the top back through the legs. For best fit measure over the diapers that you want to use. The smallest size legs measurements are taken with the cover closed on its smallest waist setting. The largest leg measurements are taken with the waist of the cover open at its largest setting. I measure all of the covers so that you can be sure that they are all measured in the same way and you can compare sizes between the brands more accurately.

When trying to decide upon a cover size, start with the suggested weights and then see if the waist, leg and rise measurements of your baby fall into the range of that cover. Check the rise on the cover that you are interested in, it will help in being more accurate on where the waist on that cover will fall on your child. If you start with the measurements you may end up with a cover that is way too big. But, you do know your baby best. Most covers have suggestions on the page as to how they fit. For all the velcro covers, you are looking for waist and leg measurements that fall in about the same place in the range. The smallest leg measurements were taken when the cover was fastened on the smallest waist setting. If your baby’s waist measurement is on the lower end of the range and the leg measurement is on the higher end of the range, the cover will probably be too tight at the legs. An exception to that seems to be the Bummis Super. The leg gussets are not sewn like the other covers and seem to be more forgiving. Since the Bummi pant doesn’t use fasteners the waist and leg measurements can fall just about anywhere on the range.

The Fuzzi Bunz covers fasten with snaps that can be fastened independently of one another. You probably won’t be able to use the smallest leg setting with the largest leg setting. Fuzzi Bunz are made to be used with an newborn 4x8x4 prefold diaper or the 4x6x4 regular prefold diaper. If you are using the Fuzzi Bunz with a 4x8x4 (the premium size) diapers and your baby is near the top of a size range, you may want to get the next size up.

Some fit tips. These are based on comments that I have heard over the years about the covers. If you have additional ideas about how the different covers fit different kids, please let me know. Bumkins (just the covers, not AIOs) - fits slender kids or ones with more slender legs better. Bummis SWW - seems to fit most kids and diapers well, good for newborns. Prorap Classic - seems to fit big (usually in the legs of the larger sizes), good for newborns.
