Size Advice from EasySize helps your users find the right size on apparel and shoes in a simple 2 step process. In this process we ask the user to select a brand and size, of for example a t-shirt they already own. Based on the user input our machine learning algorithms will calculate and recommend a size.      

When you install Size Advice, a button appears on your desired location on the product page (usually next to the size drop-down), which leads to the previously mentioned widget. The widget asks your users about the brand/size of the item they already own and based on that recommends them the size they should buy.

Size Advice takes a unique approach to solving the sizing problem. We don't use size charts, rely on customer measurements, or measure the products.

We analyze massive amounts of data to find fashion doubles and suggest the right sizes to shoppers. Fashion doubles are shoppers who exhibit similar preferences in their choice of fit, style, brand, and collection.

 The Magento extension for Easysize is FREE, however additional fees apply for the service. Simply contact us on info@easysize.me and we will create an account for you.
