Podo

say it like “poh-doh”

Parent to parent

Kids' shoe sizes are a mess. It's not just you.

You knew their size. You ordered that size. It showed up, and it still didn't fit — too tight at the toe, or roomy enough to walk right out of. Somewhere between a 13C and a 1Y, the number stopped meaning anything.

Adult sizing at least pretends to be consistent. Kids' sizing doesn't. The numbers start over halfway through, no two brands mean quite the same thing, and the feet keep changing every few months anyway. So you guess. You order two sizes. You keep the receipt and hope one of them works.

13C, then 1Y

The kids' ladder restarts mid-scale, so two sizes right next to each other can look like they have nothing to do with one another.

Every brand runs its own way

The same foot can land a half size apart — or more — depending on whose box it came in. One brand runs small, the next runs long.

Feet that won't hold still

Little feet grow in bursts. The measurement you took a few months ago is already out of date, and so is the size you memorized.

Launching soon on iPhone

Know their size
before you buy.

Point your iPhone at your child's foot. Podo measures it with the phone's AR sensors and shows the size that fits in the top 15 kids' brands and large retailers.

Three ways to measure

Different choices for different families

Two AR modes run on Apple's ARKit and Vision frameworks, right on the phone. Already know their measurement? The third mode skips the camera entirely.

01
Precision Tap

An AR ruler in the live camera. Tap the heel, tap the toe, get the distance. It's built on the same Apple AR technology behind the iPhone's own Measure app — so it should feel familiar, and it's every bit as accurate.

Live AR
02
Picture Tap

Freeze one frame, then tap heel and toe on the still. Vision snaps the pins to the foot's edge, so you can see exactly what was measured.

After the measurement

The number is the easy part.

Getting a length is where most measuring stops. Turning it into a size you'd actually buy takes a few more decisions — Podo makes them with you instead of quietly making them for you.

Both feet, every time

Almost nobody's feet match, and a shoe has to fit the bigger one. Podo measures both and sizes from the longer — so the smaller foot never decides what you buy.

Wiggle room, your call

Kids’ shoes need about a thumb’s width of space between the longest toe and the front of the shoe — for healthy balance, and to accommodate fast growth.

One profile per kid

Save each child's measurements and keep the history. Three months later, re-measure and see exactly how much they've grown — no starting over, no guessing which number was whose.

Every result comes with US kids, EU, UK, and JP sizes.
Brand sizing

One foot.
Fifteen answers...and counting.

Every brand's kids' chart lands somewhere different — the same foot can be an 8C in one brand and a 9 in another. Podo keeps one honest size ladder and a fit offset per brand, with a plain-language note on how that brand runs.
