Virtusize helps retailers to illustrate the size and fit of clothing, shoes and bags online, by letting customers compare the measurements of an item they want to buy (on a retailer’s product page) with an item that they already own (a reference item). This is done by comparing the silhouettes of the retailer’s product with the silhouette of the customer’s reference Item. Virtusize is a widget that opens when clicking on the Virtusize button, which is located next to the size selection on the product page.

You need a unique API key and an Admin account, only available to Virtusize customers. Please contact sales@virtusize.com to become a customer.
