How to Measure Kids Feet at Home

A simple 3-minute home method using paper, tape, and a ruler to get an exact measurement in inches or centimeters before ordering shoes online.

Visual Diagram: The Paper-Against-Wall Method

Heel against flat wall, vertical pencil mark, measure total distance.

Place paper flush against the wall, stand upright with heel against wall, mark the longest toe, and measure the distance in mm.

Tape Paper Flush Against a Flat Wall

Preparation

Find a hard, uncarpeted floor (hardwood, laminate, or tile). Place a blank sheet of paper on the floor with its short edge flush against an un-molded wall or baseboard. Secure the corners with tape so the paper won't slide when your child steps on it.

Pro-Tip: Avoid carpet: soft pile compresses under feet and distorts length by 4–6 mm.

Stand Child with Full Weight on the Paper

Weight Bearing

Have your child stand barefoot or wearing the typical socks they will wear with their new shoes. Ensure their heel is gently touching the wall and their full body weight is evenly balanced. Children's foot arches flatten and elongate by 3–5 mm when fully weighted!

Pro-Tip: Distracted toddler tip: give them a toy or play 'peek-a-boo' while they stand still for 10 seconds.

Mark the Longest Toe

Marking

Hold a pen or pencil completely vertical (at a strict 90-degree angle to the paper). Make a clean, straight line directly in front of the longest toe. Note: In roughly 30% of children, the second toe is longer than the big toe! Mark whichever toe extends furthest forward.

Pro-Tip: Never angle the pencil inwards under the toe curvature, or the resulting shoe will be too tight.

Measure the Distance with a Ruler (in mm)

Measurement

Use a rigid ruler to measure the straight distance from the wall edge of the paper to your pencil mark. Record the measurement in millimeters (e.g., 155 mm) or centimeters (e.g., 15.5 cm). This is your child's precise anatomical foot length.

Pro-Tip: Millimeters are more accurate than quarter-inches because shoe sizes change every 4 to 6 mm!

Repeat on the Other Foot & Take the Larger Value

Asymmetry Check

Almost all children (and adults) have one foot slightly larger than the other—sometimes by up to a half-size! Always measure both feet and use the larger number when selecting shoes or calculating sizes.

Pro-Tip: Always buy for the bigger foot. Socks and insoles easily cushion a slightly smaller foot.

5 Common Mistakes Parents Make

Avoid these five frequent home measuring traps to ensure an accurate fit.

Measuring While Sitting

When a child sits, their foot is unweighted and appears 3 to 6 mm shorter than it actually is when standing, walking, or running.

Tilting the Pencil Under the Toe

If you angle the pencil inward beneath the front curve of the toe, you under-measure the length, leading to cramped toes.

Curling Toes (Wriggly Toddlers)

Toddlers often curl their toes when tickled or inspected. Gently stroke the top of the foot to relax toes flat before marking.

Forgetting Growing Room

Buying a shoe whose inside length matches raw foot length means zero wiggle room. Always add 10–12 mm (~1/2 inch) for growth.

Measuring Only One Foot

Over 60% of kids have unequal feet. Measuring only the smaller foot guarantees tight, uncomfortable footwear on the other.

How Often Should You Remeasure?

Children's foot bones are flexible cartilage that can expand unexpectedly overnight. Pediatric podiatrists recommend following this schedule:

Ages 1 to 3 years: Remeasure every 6 to 8 weeks (~0.5 size jump every 2 months).
Ages 3 to 6 years: Remeasure every 2 to 3 months during kindergarten years.
Ages 6 to 10 years: Remeasure every 3 to 4 months during active grade school.
Ages 10+ years: Remeasure every 4 to 6 months or during growth spurts.
