Find your shoe size in Claude.

Connect GetSize to Claude and ask about your size in plain language. Answers come from the same size algorithm we use on our website.

Claude can use your other connectors at the same time. Connect Gmail too, and it can find the shoes you have bought in your order emails, so you don't have to list them yourself.

Connect GetSize For retailers

Look through my Gmail for shoes I have bought, add them to GetSize and get my size in the Adidas Samba OG.

GetSize recommends EU 45⅓ in the Adidas Samba OG.

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.

Connect GetSize in four steps.

Our size guide, in your chatbot.

Size advice from the official chart for every shoe model, inside the conversations your customers already have.

With our Model Context Protocol (MCP) integration, your store's chatbot can do what GetSize does: identify the shoe a customer is asking about, and answer with the size from the chart the brand publishes for that model.

The integration is built on the GetSize Public API, which is fully documented. Build your MCP server on top of it with your own API key; the size charts and the recommendation engine stay with us, and we keep them up to date.
