Kiwi Sizing was originally launched in 2018. Since then, this all-in-one sizing solution has received much praise and appreciation from the eCommerce business owners who use it. If you’ve recently launched your own online business on an eCommerce platform and need a sizing tool to help increase sales, read on! We’ve got ten interesting facts about this tool that’ll help you see why it’s the best sizing solution for your shop.

1. The founder of Kiwi Sizing was a Shopify store owner himself.

In 2018, our founder Sam owned a dog-apparel dropshipping business. He noticed he was spending far too much time manually converting sizing measurements to help customers find the right size for their pet. As a small business owner, he saw that the time he was wasting on this repetitive task prevented him from prioritizing more critical ones, like planning for sales growth.

As a frequent online shopper himself, Sam had also discovered that many apparel shops didn’t offer the right sizing charts to help customers choose the best fit. As a result, he frequently had to return or exchange items he bought online, which was a hassle for him and a new set of costs for the businesses he was buying from. That’s how he got the idea to create the first version of Kiwi Sizing. Since this tool was created by a Shopify store owner, it’s easy to use and affordable for other eCommerce SMBs around the world.

2. Kiwi Sizing is trusted by 13,000+ online businesses worldwide.

10 Reasons eCommerce Store Owners Are Choosing Kiwi Sizing to Help Them Grow

eCommerce brands love Kiwi Sizing! Our sizing tool has been used to create over 600,000 sizing charts and is used by more than 13,000 businesses across the globe. Kiwi Sizing is the most popular sizing solution on Shopify, with over 600 five-star reviews from businesses in industries like fitness, fashion, swimwear, lingerie, and more.

Why is Kiwi Sizing so popular? Two reasons: It’s easy to use, and it’s incredibly effective. It takes an average of 30 seconds to create a size chart for your eCommerce store with Kiwi Sizing. Once you have this accurate and consistent sizing information displayed on your site, shoppers can start making more informed buying decisions. As a result, you can build trust with customers, increase sales, and reduce the expenses associated with order returns.

3. Kiwi Sizing helps businesses reduce return rates and decrease costs.

In 2020, 21% of product returns in the US were clothing items. Customers ordering the wrong clothing sizes from online stores is bad for business, because it creates additional costs for you and more work for your customers. The mission of Kiwi Sizing is to provide store owners with an easy way to give shoppers accurate sizing information. That way, you can reduce return rates and cut overhead costs in the long term.

Kiwi Sizing tools are based on the location of your target audience, which means they’ll display the shoppers’ preferred measurement terms. As a result, you can fast-track their decision process and automatically assist them in selecting products with confidence.

4. Kiwi Sizing is more than just a simple size converter.

At Kiwi Sizing, we’re constantly optimizing and diversifying our sizing tools to serve you better. Of course, we offer convenient features like a fundamental size conversion chart—centimeters to inches, for example. But we also have more advanced tools for you to take advantage of, such as our Apparel Size Recommender. This unique widget asks users questions about their age, height, and weight, and then applies machine learning intelligence to recommend the best product sizes for them. It helps eCommerce store owners like you provide a more personalized shopping experience to increase customers satisfaction and reduce order return rates.

5. Kiwi Sizing integrates with all major eCommerce platforms.

If you’re selling on any of the most well-known eCommerce platforms, you can integrate Kiwi Sizing tools easily. Although it started as a Shopify-only app, our solution now integrates with all other primary eCommerce platforms including WooCommerce, BigCommerce, 3dcart, Magento, Volusion, Wix and more.

Creating an eCommerce website from scratch can be expensive, which is why most online sellers choose to use one of these easy-to-use options. Once you’ve set up your store with one of these, you’ll have no trouble adding Kiwi Sizing to your site so you can start providing clear sizing information to your customers.

6. Kiwi Sizing also works with other mobile and page-builder apps.

Mobile commerce is growing, and Kiwi Sizing is here to help you adapt. According to recent projections, sales from mobile commerce are expected to hit $3.56 trillion by the end of 2021. Since the majority of purchases are happening from mobile devices, it’s critical to have a mobile-optimized website and mobile-optimized tools and integrations as well.

To make it easy for you, Kiwi Sizing has integrated with various mobile and page-builder apps like Shopney and Pagefly. That means you can now quickly add your mobile-friendly sizing chart or fit recommender to your eCommerce website without the need for additional coding. Plus, as a bonus, Kiwi Sizing also collaborates with several popular Shopify apps for different types of marketing campaigns, like online forums.
