Managing a Shopify store can be a tough nut to crack, especially if you have experienced the headache of managing the refunds and returns due to size issues. Small, medium, large: these standard sizes can vary widely depending on the buyers, and the problem is that none metric is entirely standardized.

One way to deal with such an issue is by using size charts, which specify the metric you’re using to make it easier both for you and your customer. In effect, this helps you boost customer satisfaction, increase sales, and reduce returns. More than that, size charts can be used not only for clothing but also for many other types of products, like furniture, outdoor gear, accessories, etc.

With that in mind, here is a guide on how to add a Size Chart to your Shopify product pages. We will take a look at the definition, the benefits, and all the best ways to use a size chart, as well as apps to help you save time setting it up. Let’s get started!

What is a size chart

A size chart is a document that showcases the measurements for your products’ size range within your brand. Depending on the type of item you are selling or developing, you may have different measurements that are important to buyers. There is no specific size standard, so the way you want to present your sizing is up to you.

This actually leads to confusion and uncertainty among buyers when they place an order. For example, you may be able to notice that the size chart of Reebok and Nike are different because each follows a different sizing convention:

  • Reebok’s size 6 is 15cm, 7 is 17 cm, 8 is 21cm
  • Nike’s size 6 is 16cm, 7 is 18cm, 8 is 22cm

You can already imagine how helpful it would be to have a size chart for consumers when they shop online. So, let’s see all the benefits of a size chart for your Shopify store.

The benefits of a size chart for your Shopify store

  • Well-made size charts improve user experience, which in turn increases brand trust and the chance of repeat purchases;
  • They help buyers of all body shapes find a desired fit, allowing for a wider appeal of your store;
  • The charts can also become a good way to protect your business, particularly if you sell custom-made products. 

Pretty simple, huh? Just add a size chart and you can reduce the product return rate, increase sales and improve customer satisfaction.

How to add a size chart to Shopify product pages

The right size chart will need to fit your particular products and customer persona. There is no one-size-fits-all solution. So whether you are building a size chart from scratch or evaluating the possibilities for an existing guide, here are the best options to display it on the product pages:

1. Product description

product description

A visitor checking out an item should instantly bump into the size chart on your product page. If your size chart is confusing or not easily accessible, he/she is going to reconsider purchasing quickly. In the product description, place the size chart with an easy-to-understand format so buyers can quickly decide the correct size.

Try adding sizing information and suggestions in the description copy, since it is the first thing customers read. You should help them take parameters like fit, style, and elasticity into consideration. Also, you should talk about the shapes because people can’t know all about their size and body types. What looks good on an hourglass body makes it look bad on a pear-shaped boy, so touching upon shapes can be really helpful.

2. Popup


If your brand’s size chart is quite large, you can choose to hide it and appear as a clickable popup. That way, buyers can click on the popup to see the full chart whenever they feel like and close it as they wish. It is also a convenient option if buyers are using mobile to shop.

For this, however, you need to make sure that your size chart popup is mobile-responsive. If it is hard to navigate and close on mobile, customers would easily get frustrated. So the first thing you should do is to test your size chart on different screens and ensure its accessibility.

3. Homepage and Product collection

To make the chart more accessible to your visitors, consider adding it on the homepage as well. This will allow for a quick and easy customer navigation, improving your UX as a result.

You can also add it to your product collection page. That way, the chart will show buyers which items suit them straight from the beginning, helping them to save their time and efforts.

4. App


Last but not least, you can always use an app for adding a size chart to your store. The plus of such an option lies in its convenience since it often comes with already-built templates, as well as the tech support that can help you to customize the chart and ensure its correct integration with your store.

The con of using an app has to do with the fact that some of the templates need purchasing for actual use. In that case, however, you can always try free and available options, e.g. Avada Size Chart.


As you can see, adding a size chart to your Shopify store can be pretty simple and effective. It helps to improve your customer experience, reduces the rate of return and refund, and overall, leaves you with happier, more loyal customers.
