Quick Answer
The easiest way to measure your child's feet at home is to have them stand on a sheet of paper, trace both feet, and measure from the heel to the longest toe. Leave about a thumb's width (approximately ½ inch) of growing room when choosing shoes. Since children's feet grow quickly, it's a good idea to measure them every few months to keep up with healthy growth.
Every parent has been there.
One day your child happily runs around in their favorite shoes. The next day they're saying, "Mom, my shoes feel tight."
Children's feet grow quickly, and sometimes they seem to grow overnight. The good news is you don't need special equipment to check their size at home. With a few everyday items and a few minutes, you can get a reliable measurement before shopping.
At Laced Shoe in Monsey, New York, we measure children's feet every day. While nothing replaces a professional shoe fitting, these simple steps can help you choose the right size with confidence between visits.
Whether you're shopping for first walkers, school shoes, sneakers, or loafers, starting with accurate measurements helps your child stay comfortable every step of the way.
What You'll Need
You probably already have everything at home.
Gather these items:
- Two sheets of paper
- A pencil
- A ruler or measuring tape
- Socks your child normally wears
- A flat floor against a wall
For the most accurate results, measure later in the day.
Feet naturally become a little larger after walking, running, and playing, giving you a more realistic measurement.
Step 1: Have Your Child Stand
Place one sheet of paper against a wall.
Have your child stand on the paper with their heel gently touching the wall.
Standing matters because feet naturally spread when supporting body weight. Measuring while sitting often results in shoes that feel too snug later.
Step 2: Trace Both Feet
Carefully trace around each foot while holding the pencil straight up.
Try not to angle the pencil underneath the foot because it can make the outline larger than the actual foot.
Repeat the process for the second foot.
Even if one foot looks slightly bigger, that's completely normal.
In fact, many children have one foot that's a little longer than the other.
Step 3: Measure the Length
Using your ruler, measure from the back of the heel to the tip of the longest toe.
Remember, the longest toe isn't always the big toe.
Write down both measurements and always use the larger foot when selecting shoe sizes.
That's exactly how we fit children's shoes in our store.
Step 4: Compare Your Measurements to a Size Chart
Once you've measured both feet, compare the longer measurement with a reliable children's shoe size chart.

How Much Growing Room Should Kids Have?
One of the most common questions we hear is,
"Should I buy shoes a little bigger?"
The answer is yes—but only a little.
A good guideline is about a thumb's width (roughly ½ inch) between your child's longest toe and the front of the shoe.
That extra room gives growing feet space without making shoes feel loose.
Too little room can crowd little toes.
Too much room can cause slipping, tripping, and uncomfortable walking.
As New Yorkers say, you don't want to "overdo it."
The goal is a comfortable fit that leaves room to grow.
Why Measuring Both Feet Matters
It's very common for one foot to be slightly larger.
That's why we always measure both feet during every fitting.
Choose shoes based on the larger foot.
The smaller foot can usually be adjusted with socks or simple fitting accessories if needed.
If your child's loafers feel loose even though the length is correct, sizing down isn't always the answer.
Often, the extra movement comes from space across the top of the foot rather than extra length.
Our guide How to Stop Kids' Loafers From Slipping explains why this happens and how a simple tongue pad can often improve the fit.

How Often Should You Measure Growing Feet?
Children's feet change quickly.
Here's a simple guide:
- Babies: every 2–3 months
- Toddlers: every 3–4 months
- Preschoolers: every 4–6 months
- School-age children: every 6 months
If your child suddenly starts complaining that shoes feel tight or keeps taking them off after school, don't wait for the next shopping trip.
Measure again.
Choosing the Right Shoes After Measuring
Knowing your child's size is only part of finding a great fit.
Different styles fit differently.
For example:
Our First Walkers Collection is designed with soft, flexible soles that encourage natural movement during those exciting first steps.

A Tip From Our Shoe Fitting Team
One of our favorite moments is seeing a child put on shoes that truly fit.
Parents often smile and say,
"I didn't realize the old pair had gotten so small."
Kids stop curling their toes.
They walk more naturally.
And sometimes they even want to keep the new shoes on all the way home.
Those little moments remind us that shoe fitting isn't just about size.
It's about comfort, confidence, healthy movement, and letting kids enjoy being kids.
