Baby Knitting Size Chart – Very Premature, Premature, Newborn & 0–12 Month Sizes
Choosing the correct size is one of the most important parts of any knitting project. Whether you're knitting for your own baby, creating a thoughtful handmade gift or making clothes for a reborn doll, selecting the right size before you cast on will help you achieve the best possible fit.
Babies grow quickly and every baby is different, so choosing the right size isn't always as simple as selecting an age. This baby knitting size chart explains the typical measurements for very premature babies, premature babies, newborns and babies up to 12 months, helping you choose the most appropriate knitting pattern size while understanding how babies typically grow during their first year.
DollieBabies baby knitting patterns are designed using the baby's approximate weight and height rather than age alone. This provides a more accurate guide because babies of the same age can vary considerably in size. Many patterns also include reborn doll sizes, making them suitable for both babies and dolls.
Baby Knitting Size Chart
| Baby Size | Typical Baby Weight | Typical Baby Height |
|---|---|---|
| Very Premature | Up to 3 lb | Up to 14″ |
| Premature | 3–5 lb | 14″–17″ |
| Newborn | 6–9 lb | 18″–21″ |
| 0–3 Months | 9–12 lb | 21″–24″ |
| 3–6 Months | 12–16 lb | 24″–26″ |
| 6–12 Months | 16–22 lb | 26″–30″ |
These measurements are intended as a general guide, as babies grow at different rates. Many knitters choose to knit a slightly larger size so that garments can be worn for longer.
While this chart includes typical baby measurements up to 12 months, most DollieBabies baby knitting patterns are available in sizes from very premature to 9 months. The 9–12 month measurements are included as a general guide to help you understand how babies continue to grow during their first year.
Understanding Baby Knitting Sizes
Although baby knitting patterns are often described using age ranges such as newborn or 0–3 months, babies don't all grow at the same rate. Some babies are born much smaller than average, while others may be large enough to wear 0–3 month clothing from the day they are born.
For this reason, DollieBabies baby knitting patterns use the baby's approximate weight and height as the primary guide, with age included where appropriate. This makes it much easier to choose the size that's most likely to fit, especially if you're knitting before the baby arrives or making a gift for someone else.
Some DollieBabies patterns also include additional very premature and reborn doll sizes, helping you knit for tiny babies from approximately 1 lb in weight. These smaller sizes are identified within the pattern using the baby's approximate weight and height.
Choosing the Right Knitting Pattern Size
When selecting a baby knitting pattern, it's helpful to consider:
• the baby's current weight
• the baby's approximate height
• whether you're knitting before or after the baby is born
• whether you'd like the garment to fit immediately or allow room for growth
If you're knitting before the baby arrives and don't know how big they will be, newborn or 0–3 months is often a sensible choice. If the baby is expected to arrive early, choosing a pattern that includes very premature or premature sizing can provide a better fit.
