This post is the first part of a multi-parts series on how to use Kiwi Sizing to improve your conversions.

Whether you're a new shop or an experienced business, adding size charts to your clothing products is an indispensable step to a functional and optimized product page. Being in the business for many years, we have seen many common issues people have with regards to size charts:

  • Reusing the size images given by their vendors or suppliers. This leads to an inconsistent experience for your customers.
  • Missing unit conversion features. Our target consumers are often multi-national, and size charts should make it easy for both people who prefer centimeters and those with inches.
  • Not having size chart in product pages. We often see shops with only a standalone size guide, but it is best to have size charts directly next to the add-to-cart button to reduce the chances of buyers dropping off.

With Kiwi Sizing, you can set up size charts most optimized for conversion. The tool is intuitive and you can create and manage tens or even hundreds of different size charts in 1 place.

This article will walk through the steps to set up your first size chart using Kiwi Sizing. Note that while we will use our Shopify as an example but the tool can be used for any other e-commerce platforms such as BigCommerce, WooCommerce from Wordpress, 3dcart and Magento.

Now let's get started!
