The size diaper cut you need to have lots of room to sew is a 20X22" cut. You can also use 20X20" diaper cuts along with wing embellishments of a different color or print of PUL.

The highest rise is 19" but due to the angled front and back the front needs more room at the ends of the front panel and the back is taller in the center. If you also purchase the flawless fit in the future it pairs well for using yards of PUL because it only uses a 17X19" cut. (It will fit 7-32lbs)
