Finding a knitting pattern specifically for a 3 year old can be surprisingly difficult. Children’s patterns are often grouped into wider age ranges, so you may find sizes labelled 2–3 years, 3–4 years or simply 2 and 4 rather than an exact age-three size.
I’ve gathered 10 free knitting patterns that include a suitable toddler size, with sweaters, cardigans, a vest, summer top and hooded jacket to choose from.
Before starting, check the measurements given in the individual pattern rather than choosing by age alone. Children of the same age can be very different sizes, and you’ll also want to consider whether the finished knit will be worn on its own or layered over other clothes.
Free children’s knitting patterns to download, most of these patterns are for ages 2 to 10 years old, so you will definitely find something to knit that is perfect for a 3 year old boy or girl.

1. School Days Raglan Pullover
The School Days Raglan Pullover is a classic children’s sweater with a simple round neckline and raglan sleeves. It’s an uncomplicated everyday style that works equally well for boys or girls, with your yarn colour making it easy to personalise.
Size for a 3 year old: The pattern includes sizes 2, 4, 6, 8 and 10 years. Check the pattern measurements to decide whether size 2 or 4 provides the best fit for the child you’re knitting for.
Skill level: Easy

2. Girls Skinny Tank Top
This Girls Skinny Tank Top is a lightweight sleeveless knit that’s particularly useful for warmer weather. It gives you something quite different from the heavier sweaters and cardigans in this collection and can be worn alone in summer or layered when the weather cools.
Size for a 3 year old: 2–3 years. Larger sizes through 10–12 years are also included.
Skill level: Intermediate
Why choose it: The sleeveless design makes this a good choice if you’re looking specifically for a knitted summer garment rather than another warm toddler sweater.

3. Classic Kid’s Pullover
The Classic Kid’s Pullover is a timeless unisex sweater with raglan sleeves and a traditional crew neckline. It’s the sort of practical knitted sweater that can be made again in different colours as a child grows.
Size for a 3 year old: Sizes 2, 4, 6, 8 and 10 years are included. Compare the measurements for sizes 2 and 4 with the child before deciding which to knit.
Skill level: Intermediate
Why choose it: This is one of the most traditional designs in the collection. Choose it if you want a straightforward children’s sweater rather than a particularly decorative or fashion-led style.

4. Seahorse Tee
The Seahorse Tee, designed by Rachel Brockman, brings some fun to children’s knitting with a large seahorse motif worked on the front. Contrasting edges add another splash of colour, making this a particularly appealing warm-weather knit.
The seahorse is worked using intarsia, so this pattern is also an opportunity to practise picture knitting on a relatively small garment.
Size for a 3 year old: The pattern includes sizes 2, 4, 6, 8 and 10 years. Use the finished measurements to choose between the two smallest sizes.
Skill level: Intermediate
Why choose it: Pick this one if you want something more interesting than a plain sweater and enjoy knitting with colour. It is not the easiest pattern on this page because the seahorse introduces intarsia.

5. Knitted Baby Vest
This Knitted Baby Vest is a practical sleeveless option that can be layered over a shirt or long-sleeved top. Unlike a traditionally constructed vest made from separate front and back pieces, this design is worked top-down in one piece.
Size for a 3 year old: 3–4 years.
Why choose it: With no sleeves to knit and an all-in-one construction, a vest can be a useful alternative when you want to make a child’s garment without committing to a full sweater.

6. French Macaroon
The French Macaroon by Caro in the City is one of the simplest-looking sweaters in the collection, with a boat neckline, contrasting colour sections and a small button closure at the back of the neck.
It’s knitted in garter stitch, giving the sweater plenty of texture without requiring a complicated stitch pattern. The front and back are worked separately, the shoulders are joined, and only a small amount of seaming is required.
Size for a 3 year old: 2–3 years, with additional sizes from newborn through 4 years.
Yarn weight: DK
Why choose it: This would be one of my picks for someone wanting relatively simple knitting. Garter stitch keeps the stitchwork straightforward, while the two-colour design makes the finished sweater look more interesting than the techniques involved suggest.

7. Tamzyn
Tamzyn by DROPS Design is a colourful garter stitch jacket made using a domino-style construction. Rather than looking like a basic children’s cardigan, the geometric sections and colour changes give the finished garment plenty of personality.
Why choose it: The individual stitchwork is straightforward because the jacket uses garter stitch, but the construction is more unusual than a conventional cardigan. It’s a good choice for a knitter who is comfortable with basic stitches and wants to try something different.
This is one I would choose for simple stitches but interesting construction, rather than as the most conventional first children’s garment.

8. Striped Sweater
The Striped Sweater for Kids by Debbie Bliss is a cheerful children’s sweater that uses stripes to create most of its visual impact. It’s a useful choice if you want a colourful toddler knit without having to follow an intarsia picture chart.
Size for a 3 year old: Sizes 2–3, 3–4 and 4–5 years are included, making this one particularly useful when you’re trying to find a close age match.
Skill level: Easy
Why choose it: Stripes are an approachable way to introduce colour to a child’s sweater. You get a much more playful finished garment without the additional technique required for picture knitting such as the Seahorse Tee.

9. Kimes Cardigan
The Kimes Cardigan by Taiga Hilliard is a simple button-front cardigan designed for boys or girls. It is knitted seamlessly from the top down, with the button bands worked as part of the cardigan rather than added afterwards.
The sleeves are placed on hold while the body is completed and are then returned to the needles and knitted, making this quite different from a traditional cardigan assembled from several separate pieces.
Size for a 3 year old: 2–3 years. The pattern also includes sizes from newborn through 4–6 years.
Yarn weight: Bulky
Why choose it: Kimes is a particularly good option if you dislike sewing knitted garments together. The top-down construction eliminates traditional seaming, while bulky yarn helps a small cardigan grow relatively quickly.

10. Classic Kid’s Hoodie
The Classic Kid’s Hoodie combines the practicality of a cardigan with the extra warmth of a hood. It has a traditional button front and is designed as a unisex children’s garment, so it can easily be adapted for different children simply through your yarn choice.
Size for a 3 year old: The pattern includes sizes 2, 4, 6, 8 and 10 years. Check the measurements of the two smallest sizes to decide which gives the amount of growing and layering room you want.
Skill level: Intermediate
Why choose it: This is the most practical outer layer in the collection. Choose it when you want something that can be worn over other clothes rather than a simple indoor sweater or top.

We hope you enjoy these free toddler, 3 year old children’s knitting patterns as much as we do. Most of these patterns are unisex, your yarn color choices can determine whether this adorable hand made knitwear is for boys or girls.
What Is the Easiest Thing to Knit for a 3 Year Old?
If you’re relatively new to garment knitting, look first at patterns that combine simple stitches with uncomplicated construction.
The French Macaroon is particularly appealing because it is worked in garter stitch, so most of the knitting consists simply of knit stitches. The Kimes Cardigan uses a different approach: its top-down construction reduces the amount of seaming required.
The Striped Sweater is another approachable choice and is rated Easy, while the stripes add colour without requiring intarsia.
Don’t assume that a smaller child’s garment is automatically easier, however. A tiny sweater can still include neckline shaping, sleeve construction, picking up stitches or colourwork. Check the techniques as well as the size before choosing your project.
What Size Should I Knit for a 3 Year Old?
There isn’t one universal knitting-pattern size for every three-year-old.
In this collection alone you’ll find patterns sized 2–3 years, 3–4 years and numbered sizes 2 and 4. That’s why I recommend using age as your starting point rather than your final sizing decision.
If you can measure the child, compare their chest measurement with the sizing information supplied by the pattern designer. Then look at the finished garment measurement where it is available.
Also consider how the garment will be worn. A fitted summer top may need relatively little extra room, whereas a hoodie or cardigan worn over other clothes needs enough ease for comfortable layering.
Frequently Asked Questions
Possibly, but check the actual garment measurements first. A child approaching age four may fit a 3–4 year size better, while a smaller three-year-old may still fit the 2–3 size comfortably.
Use the child’s measurements whenever possible. If they fall between sizes, also consider the garment style, intended ease, season and how soon the finished item will be worn.
A pattern using garter stitch, stocking stitch or another simple stitch pattern lets you concentrate on learning garment construction. From this collection, French Macaroon is worth considering because its garter stitch fabric is particularly straightforward.
No. Several patterns in this collection are unisex, including classic sweaters, cardigans and the hoodie. Colour is only one way to personalise a child’s knit; yarn fibre, buttons and finishing details can also completely change its appearance.
It often can be because there are no sleeves to knit. That removes a substantial part of the project as well as some of the shaping and finishing that sleeves can require.
Look first at the yarn weight and gauge specified by the individual pattern. For children’s clothes, also consider softness, durability and how easily the finished garment can be washed. If substituting yarn, matching gauge is more important than simply choosing another yarn labelled with the same weight.
