How to Measure for the Perfect Fit
Your baby's age and/or weight won't always ensure a comfortable, leak-proof diapering fit. Diapers and diaper covers need to be tailored properly to fit well. Their design needs to prevent leakage, without being overly bulky.
Three critical areas are waist, crotch depth (from the front waist band, through your baby's legs to the back waist band) and crotch width (measurement between your baby's legs).
The waist should be able to adjust to fit your baby . . . too wide, it will fall off your newborn. Too small and it won't fit around your baby's chubby belly. For your diapers, the crotch depth should be long enough to last till toilet training, yet short enough that your newborn won't be lost! For your diaper covers, the crotch depth must cover your diapers to prevent leaks. If the crotch fit is too narrow, your diapers will leak; too wide, and the fabric could bunch up, making your baby uncomfortable.
For longer wear, your baby's measurements should be closer to the lowest measurement range of the listed diaper or cover. (For covers, remember to measure over your diapers and any liners used). The closer to the top range of measurement, the shorter the wear your baby will get, and the tighter the fit! However, once your baby is mobile, that chubby belly and fat thighs will slim right down.
For best leakage protection, your baby should be at least at the lowest measurement range around the legs and waist. Otherwise gaps will form, allowing leaks through to your baby's outer clothing.
The lowest number is the measurement when the elastic is at rest, or the diaper/cover is fastened at its smallest closure. The higher number is the measurement when the elastic is stretched to its maximum, or the diaper/cover is fastened at its largest closure.
Since flat and prefold diapers depend on the folding method you use, I have only listed the actual dimensions of the diaper, prior to any folding. However, you can assume the longest measurement is the maximum crotch depth fit. Twice the shorter measurement is the maximum waist fit. However, if you were to fold it into a wrap cover, the flat or prefold could fit even longer.
Shaped diaper fit depends on the fastening method your use, or whether the diaper is used inside of a wrap cover. Therefore I have only given an approximate range. Again, wraps can extend the fit of shaped diapers. Remember that the sides and length of a larger shaped diaper could be folded to fit your smaller baby.
Here's a great suggestion to fit your newborn, or skinny baby! Consider getting the smaller wraps, and using night liners inside to ensure a good fit around your baby's legs to prevent leakage. Then you can get larger diapers that will give your baby longer wear, and use the night liners again to double diaper when your baby wettings get heavier!
Waist Fit: measure around baby's waist at navel. Measure over diaper for cover fit.
Depth Fit: Measure from baby's navel, between legs to above baby's bottom. For covers, measure over a diaper.
Crotch Fit: Measure between legs at front. Measure over diapers for covers.
Leg Fit: Measure around the fullest part of baby's thigh.
