Size Guide Examples in eCommerce

Processing and handling returns hurt profits. One way to reduce this is to create size guides to better detail your product’s dimensions and display it on your product pages.

Size guides are a great way to keep customers informed when making purchases on your online store. You can expect to see a reduction in return orders as a result of people ordering sizes that fit them. This can help your business save costs and offer a better online shopping experience.

In this article, we’ll go over some outstanding eCommerce size guide examples and see how you can include them in your own store.

Why are size guides useful?

Size guides are essential for reducing return orders. They provide accurate sizing information to customers when they’re browsing a product on your eCommerce store.

For instance, if you sell apparel products such as t-shirts or hoodies, you can create a size guide that lists the sizes of the chest, arms, and shoulders area for the product. This way, customers can select the size that fits them best before adding the apparel product to their shopping cart.

On the other hand, without a size guide, you’ll leave it in the hands of your customers to essentially “guess” their size. In fact, more than 80% of apparel stores online don’t provide enough sizing information to their customers. This not only makes it more likely for customers to return the order due to a wrong size selection but also reduces the chances of those customers ordering again from your online store.

It’s also important to understand that size guides often vary between different stores, vendors, and countries. For example, if your online store operates out of the US, you will need to create a size guide with the imperial system. Similarly, if you sell to EU customers, your size guide will need to use the metric system. A person shopping for shoes might buy pairs in sizes 7.5, 38, and 9 all indicative of the same shoe size!

Depending on the type of products you sell, you might also want to include tips in the size guide that explains how to measure. Measurement instructions are particularly important for wearables such as apparel and jewelry. The idea is to explain how customers should take their measurements to determine their correct size. It’s also helpful to provide a model or diagram to visually explain how to take measurements.

It’s a good idea to use a size guide on your online store to provide sufficient sizing information for your products. Let’s quickly take a look at some of the benefits of creating size guides for your online store:

  • Encourage customers to make purchases. Showcasing a size guide directly on product pages can help your customers make informed purchase decisions. This also means if your product pages provide enough sizing information, customers will feel more comfortable adding the products to their cart. As a result, you boost sales and encourage more purchases on your online store.
  • Customers don’t bounce off your site. Another big reason why you want to show a size guide on your product pages is to prevent prospective customers from bouncing off your site without making a purchase. This is because if a user is looking to spend money to purchase a t-shirt or a pair of sneakers, they will want to make sure it fits them perfectly.
  • Reduce return orders. If all customers are ordering the exact sizes they need, it reduces return orders on your online store due to a wrong sizing issue. As a result, you don’t have to spend as much on processing and handling returns.

Size guides are essential for most eCommerce sites such as apparel stores or clothing brands that want to let their customers view and purchase products directly from their websites.

However, this doesn’t mean it’s not useful for other types of online stores. For example, an online furniture store can use a size guide to specify the dimensions of a sofa or a table. Similarly, an online PC accessories store can use a size guide to specify the sizes of mousepads and vinyl stickers.

Put simply, a size guide is a universal way of showcasing additional sizing information for the product customers want to add to their cart. Without it, customers aren’t comfortable spending money on your site. And, even if they do, there’s a pretty good chance it’ll end up costing your business more in processing and handling the returns.

Great examples of size guides

Here, we’ll take a look at some different examples of size guides and see what they did right. This can help you get inspiration for the perfect size guide for your online store.

#1. Posse

Posse is a popular online apparel website that offers a neat size guide that helps its customers choose the right product size when placing their orders.

This also means they have created a size guide for users who want to order online so they can easily choose the correct size for their wrist from the comfort of their home. This includes additional information on the dial sizes and band sizes of watches to make it easier for customers to choose the one that they want while ensuring it fits them well.

The standout feature of TAG Heuer’s size guide is that they let their customers download the size guide and print it to measure their band size accurately.

#3. Lenskart

Lenskart is another great example of how size guides are useful regardless of the type of products you sell on your online store. It’s an online store that lets its customers order their glasses by simply selecting their lens number and choosing the right size of the glass frame.

This is important since customers don’t really have a way of knowing whether the glasses will fit their faces or not when buying glasses online. A size guide similar to this informs customers how to measure and select their correct glass frame size in two different ways.

#4. Bloomscape

Bloomscape’s approach to a sizing guide is very simple yet is an effective way of informing customers about how much space a plant will take in their home or office.

While they have included accurate sizing dimensions for customers to measure themselves, there are also images of humans holding the plant for comparison. This gives their customers a better understanding of what size they’re looking for.

#5: TOMS

TOMS uses a “Size Chart” or their version of a size guide to let customers convert their shoe measurements into a shoe size.

The best part is that it includes a separate column for each region so users from all over the globe can use their size guide. This not only helps customers make informed purchase decisions but is a great way to cater to all types of customers despite their geographical location.

Size guides in WooCommerce

While size guides are a handy thing to have for your online store, the core WooCommerce plugin doesn’t let you create one. This is why you need to use an additional plugin to include this functionality.

CommerceKit is one of the best solutions for creating better-looking product pages on your WooCommerce site. CommerceKit is available exclusively as part of the Shoptimizer WooCommerce theme.

You can create and design your size guide as you please. This means you can showcase additional information as a way to inform customers how to measure their own size when ordering from your online store. Adding images is also a great way to visually explain how customers are supposed to measure their size.

You can then create a size chart or a sizing information table using the Table block.

Fill out the size chart entries.

It lets you add header sections and specify the dimensions that customers need to measure when purchasing apparel products from your online store. This helps them decide on the accurate size that will fit them perfectly so they don’t have to return their order later. Click on the Publish button to continue.

Step #3: Select categories to display the size guide

Once you’re done designing your unique size guide for your WooCommerce products, it’s time to decide where the size guide will be displayed on the front-end. To do this click on the Size Guide tab from the More settings page of your screen.

Select product categories.

Click on the Product Categories dropdown and specify which WooCommerce categories the size guide will be displayed on. Similarly, you can also specify specific products and create size guides to be displayed for unique products on your online store. Once you’re ready, make sure to click on the Update button.

Link to the size guide on the product page.

Specifying a category earlier makes the size guide visible on all products in that category. Customers can click on the Size Guide button on product pages and it will automatically open the size guide on the same page.

While creating a size guide is essential for online apparel stores, it’s also useful for many other types of online stores. As a result, it helps prevent returns due to incorrect sizing or fitting and helps your business save costs.
