Prefold nappies are a hard wearing economical cloth nappy system, although they are sized you don't need to buy every size, imagine prefolds are available as unbleached, white bleached or bamboo, the favourate here are the bamboo followed by the unbleached as these stay softer then the bleached white prefolds.
Imagine prefolds are smart fit meaning they are shorter and wider then normal prefolds therefore they are easily folded in 3 and placed in a wrap for fast nappy changes, if you want to be able to fold the prefold and fasten with pin or nappi nippa you will probally need to size up.
About "Smart Fit" Prefolds
Imagine "Smart Fit" prefolds are like Chinese prefold diapers and DSQ
prefold diapers (diaper service quality) except 100% cotton twill from
India and sewn in Pakistan. Indian cotton is known to be a superior
material used in prefolds. To improve the quality even more they are
stitched with high quality thread and the stitches are reinforced. Plus,
a special process is performed during manufacturing to eliminate
pilling! "Smart Fit" prefolds are cut shorter and wider to fit into
diaper covers better, often without any folding in the rise necessary!
They are soft, highly absorbent, and super durable. These prefold
diapers can withstand many rigorous washings and dryings as well as can
be used on multiple babies over the years. The uses do not stop there -
and they can be used after the diapering years as cleaning rags!
All prefolds are 4x8x4 except extra small 3x6x3
