The family size book

Know everyone’s size before you reach the checkout.

ShoeSizeBook keeps each family member’s shoe, shirt and pants sizes in one place, with the date you measured. Open it in the shop and buy the right size the first time.

Free to start. No card needed.

Sound familiar?

“What size was she in last winter?”

“Is that an EU 33 or a UK 1?”

“It’s written on a note. Somewhere.”

Children outgrow shoes quickly, and every brand labels them differently. ShoeSizeBook is the one place the answer lives.

How it works

Three steps. About a minute each.

A history, not just a number

Every size keeps its date. See how fast feet are growing and judge when the next pair is due.
