GetSize

The size guide that follows you.

Every shop has its own size tool, and what one shop learns about you stays in that shop. We think you should have access to your data everywhere you shop.

GetSize is your personal size guide for shoes. It tells you which size to order in any shoe model, based on the official size chart the brand publishes for that model. We are independent of any retailer, so you can use it wherever you shop.

Add the shoes you already own and tell us how they fit. It is all saved in your GetSize account, so that it's always ready for your next purchase.

Your size guide, in Claude.

Connect GetSize to Claude and ask about your size in your own words. By connecting Gmail, Claude can import the shoes you already own to GetSize automatically.

You don't need a GetSize account. Shoes you add through Claude are not saved to an account.

Claude reads your email through your own Gmail connection. GetSize receives the shoes, sizes and fit details Claude adds, and any foot measurement, with no name or account attached. We keep the shoes and sizes anonymously as part of the data our recommendations are built from. The session itself expires after seven days without use.

Our recommendation engine.

Two shoes from the same brand can follow different size charts, and a running shoe can be cut differently from a lifestyle sneaker. Most stores don't have the capacity to manage this complexity, and show one generic chart for the whole brand.

GetSize solves this by mapping each model to its official size chart. Our recommendation engine combines those charts with your own fit feedback on the shoes you already own, and finds your size in the model you want to buy.

To get your size, all you need to do is tell us which shoes you already own.

Official size charts for every model.

Our mission is to collect the official size chart for every shoe model, from every brand, and keep each one up to date. Use them to find your size with our size tool, or build them into your own store or app through our API.
