Please note all of our sizes are our own and should not be compared to other brands or expected to fit similar to any other brands sizing we do have a gallery to compare but each shape and arrangement of buttons etc changes how each diaper fits so this is only for you to get a basic idea on if they will fit your size needs the comparisons are never exact due to how different various shapes and brands can fit on each baby.
At SUS we have tried very hard to come up with our own sizing so our diapers are all larger than typical when fully unsnapped but they all snap down smaller to fit a wider size range than most on the market. We did this because we want every diaper we create to fit longer so you get a lot of use out of them and they will last for the entire duration of each growth phase.
We have tried very hard to create a diverse and inclusive size range and hope this helps find what size you need. we also have comparison galleries in our facebook group albums found here
