Sizing has always been a critical issue for eCommerce merchants who sell apparel—and digital sizing tools like Kiwi Sizing are designed to help. Kiwi Sizing was first released for Shopify in 2018, and has since been integrated with additional eCommerce platforms including WooCommerce and BigCommerce. If you’re selling online with any of these platforms, here are the top four reasons you should add Kiwi Sizing to your suite of sales-boosting tools.

#1. Quickly and easily create multiple sizing charts

If you sell apparel for different genders or age groups, you’ll need to provide different sizing charts for each one. In the past, online merchants used Excel or Adobe Photoshop to manually create as many size charts as needed for their stores. However, unless you’re a highly proficient user of these software products, doing it this way can be time-consuming and costly—especially if you have several different product types to make charts for. Plus, your charts are more likely to end up with errors, which defeats the whole purpose of providing a helpful sizing tool to customers.

That’s where a tool like Kiwi Sizing comes in. It’s a far more user-friendly and cost-effective way to produce sizing charts for your WooCommerce store. You can select standard charts for more basic items, or quickly create a custom chart for more unique items. Either way, you’ll end up with an easy-to-read guide to help your customers choose the right size for them without spending too much time, money, or human resources designing it yourself.

With Kiwi Sizing, you can easily create multiple sizing guides in the following formats:

  • Standard size charts: Professional sizing charts that can be integrated into all major eCommerce platforms (Shopify, BigCommerce, WooCommerce).
  • Apparel Size Recommenders: A tool that asks the shopper a few questions about their body type, and then recommends the best fit for them using AI.
  • Custom Size Recommenders: The ability to easily create your own, custom size-recommendation logic for any type of product you may sell.

Once you’ve added the basic content for your size chart, you can also add additional materials to help your customers make more educated purchases. You can embed fitting videos or product pictures, for instance, or extra tabs with additional information like how sizes are measured or what the material is like. With Kiwi Sizing, you have the freedom to add as much detail as you want to help prospects buy with confidence. Finally, you’ll also have the option to customize your size charts with colors and styles that match your brand image, so you can create a more cohesive online shopping experience.

#2. Offer automatic unit conversions in a single click

The way clothing sizes are measured can differ from country to country, and it’s your job as an online merchant to provide the right conversion information to individual customers. Mobile commerce has reshaped customers’ shopping behavior, conditioning them to expect instant answers. If you require a customer to do their own unit conversions in order to figure out the right size for them, they’re likely to get impatient and abandon your site altogether.

That’s why you should be sure to display the correct sizing units for any particular customer. With Kiwi Sizing, customers can view sizing information in alternate units with a single click, making it easy for them to quickly understand which size to choose. The results: Shoppers will enjoy a smoother and less frustrating shopping experience, and will be able to make more conscious and accurate purchase decisions more quickly. For new apparel stores, this ease of conversion can serve as the competitive advantage that sets you apart and helps you build a loyal customer base over the long term.

#3. Embed a personalized fit recommender for all body types

Personalization is rapidly becoming a key factor in predicting whether customers will make repeat purchases with a particular store. In fact, nearly 50% of consumers surveyed say they’re willing to spend more money with a brand that personalizes their eCommerce experience. As a result, many online retailers have started integrating AI and machine learning into their sizing tools to provide a more customized experience.

The good news: You don’t need detailed knowledge of artificial intelligence to incorporate its capabilities into your store’s sizing charts. Kiwi Sizing offers WooCommerce merchants three easy ways to harness the power of AI to provide personalized sizing recommendations to customers:

  • Advanced Apparel Recommender: Offers apparel size recommendations from basic information (i.e. age, weight, height, gender) entered by the customer. This tool has been shown to result in the lowest dropout rate during the shopping process.
  • Simple Generic Table Apparel Recommender: Provides the best fitting suggestion using specific body measurements (i.e. chest, waist, hips) entered by the customer. This type of tool typically provides highly accurate fit recommendations; however, merchants need to keep in mind that not all shoppers know their measurements or have the means to easily take them.
  • Custom Recommender: A completely flexible size recommender that allows store owners to input their own recommendation logic. This type of tool works well for products with unique sizing conventions, such as bras or sports equipment.

By providing customers with an easy way to choose the right size, you’re improving their experience with your brand and building trust. Plus, you’ll also reduce your return rate and the associated costs, which will help boost your brand’s long-term success.

No matter what type of apparel you’re selling, a well-designed size chart should include all product details that matter to your customers (including length, material type, color, unit conversions, etc.). That’s why you should select a sizing tool that allows you to modify and replicate sizing charts easily, so you can quickly complete all your product listings and start selling right away.

Kiwi Sizing offers more than 10 size chart templates for sellers to choose from, so you can get up and running quickly. Once you choose a template you like, you can start adding product information and editing the chart immediately. You can decide on the colors and information format (i.e. image, video, text, image with caption) you want to use, and then apply it to all other products so as to keep everything consistent throughout your website. That way, you don’t have to do manual updates for each one. If you’re looking for a helpful, informative sizing tool you can implement and update with speed and ease, Kiwi Sizing should be your top choice.
