Toddler Sweater Measurements - A child's size 3T toddler sweater is quickly outgrown but that does not stop avid knitters from creating Mini Me sweaters in toddler sizes.

In this post, we discuss the Toddler 3 size specifically but you can scroll to the bottom of this page for a link to all measurements for the full range of children's sizes up to a Child's size  14.

Questions about toddler sweater measurements are among our most frequent inquiries. Wondering about sweater measurements for a 3-year-old child?

Today’s three year old is far from toddling, but height and weight will also affect the size your child wears. Don’t forget that the size “3” actually comes in two sizes: the Toddler3 and the regular size 3.   Toddler sizes tend to be shorter and wider than the corresponding child’s size.

Toddler Sweater Measurements: Sizing Details

In knitting children's sweaters, we use the sizing chart below when designing the "standard" toddler's size 3.

We also add growing room (aka extra wearing ease) to all designs for children up to the size 14.

Use the chart as a guide to help you pick the correct size to knit for your child or grandchild. A three year old may need a size 4, a 4T or even a size 5.

Wondering why there are no buttons on the lavender and white striped toddler sweater? I could never make up my mind as to which one to select! Eventually, I picked cute little white flowers but the selection of decorative buttons for childrens clothing is unbelievable. Check out this collection of buttons!

As a rule, consumers tend to purchase clothing for infants, babies and toddlers according to their age, but different manufacturers follow different sizing guidelines.  

It is good to remember that any knitting pattern (even patterns for babies and toddlers) is drafted according to style, fit and the designer's own set of measurements.

These measurements may not be anywhere near what you need so just  measure the child and go with those measurements.   The details provided below are body measurements  not  finished garment measurements.

Always view the "age" and "measurements" as averages for that particular age group.   As we mentioned in an earlier post, children of the same age come in many sizes.

A good case in point are Hobbie's twin elves...well into sizes 6/7 while still 4 years old due to height and weight well above the median percentile for their age group.  

They are far from plump - in fact, right now they look skinny as a rail but they're just destined to be tall and built accordingly.

Which Toddler Size Should I Knit?

If your child's measurement hovers between two sizes,   don't hesitate to pick the larger size.   You may even need to customize the measurements for what I refer to as the "now and a little later" fit.  

Why spend the time knitting if the sweater will only fit for a few months? Sweaters are outerwear, designed to be worn layered over other garments such as turtlenecks or long sleeved shirts.

Be sure to compare your child's actual measurements to those of the standard/average toddler sweater measurements for a 3T, the regular size 3 AND to the measurements provided with your knitting pattern.  

In my experience, the toddler size 3 will probably fit a 2-year-old perfectly.

How To Knit A Toddler Sweater in Size 3T: Measurements

  • Full Chest = 22 inches;
  • Hips = 22.5 inches;
  • Shoulder width = 10 inches;
  • Arm length = 13 inches.

Knit the sweater to the following finished measurements:

  • Chest/hip = 24 1/2 inches;
  • Sleeve length = 13 inches;

Finished cardigan length for a size 3T – about 14 to 14.5 inches.

Length is totally adjustable. For the twins, I needed to adjust to nearly 16 inches.

Sleeve and body length can be adjusted for a perfect fit by adding several rows just before the underarm shaping.
