Baby Knitting Size Chart – Premature, Newborn & 0–12 Month Sizes
When choosing a baby knitting pattern, one of the most common questions knitters ask is “What size should I knit?”. Babies grow quickly and sizing can vary depending on age, weight and length, so it helps to understand typical baby measurements before starting a project.
This guide explains common baby knitting sizes from premature through to 12 months, helping you choose the correct size for your knitting pattern.
Many DollieBabies knitting patterns include a wide range of sizes, making them suitable for both premature babies and older infants, and in some cases the same patterns can also fit reborn dolls of similar height.
Baby Knitting Size Chart
| Baby Size | Typical Baby Weight | Typical Baby Length |
|---|---|---|
| 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 general guidelines, as babies grow at different rates. Many knitters prefer to knit slightly larger sizes so that garments last longer.
Understanding Baby Knitting Sizes
Baby knitting patterns are usually written using age ranges or baby weights rather than exact measurements.
For example, a knitting pattern may include sizes such as:
Premature baby
Newborn baby
0–3 months
3–6 months
6–12 months
These sizes are designed to fit the average measurements for babies in those age ranges.
Choosing the Right Knitting Pattern Size
When selecting a baby knitting pattern, it is helpful to consider:
• the baby’s current weight
• the baby’s approximate length
• whether you want the garment to fit now or allow room for growth
If you are knitting as a gift and are unsure of the exact size, choosing newborn or 0–3 months is often a safe option.
Popular Baby Knitting Projects
Many knitters enjoy creating handmade garments and gifts for babies. Popular baby knitting projects include:
-
Baby cardigans
-
Rompers and dungarees
-
Baby bodysuits and vests
-
Hats and bonnets
-
Booties and socks
-
Matching baby outfit sets
These smaller garments are often quick to knit and make thoughtful handmade gifts for new babies.
Yarn for Baby Knitting
Baby garments are typically knitted using soft yarns that are gentle against a baby’s skin.
Common yarn weights used in baby knitting patterns include:
4ply yarn – ideal for lightweight garments such as cardigans, rompers and hats.
Double knitting (DK) yarn – commonly used for warmer garments such as jackets, dungarees and baby sets.
Soft acrylic baby yarns and machine-washable yarns are popular because they are practical for everyday use.
