Why a Size Table Section Is Essential for Clothing Stores on Shopify

Selling clothing online comes with one major challenge: customers can’t try the product on.

One of the main reasons shoppers hesitate—or return items—is uncertainty about sizing. A clear and well-designed size table section removes that uncertainty, builds confidence, and significantly improves conversions on your Shopify store. Key features of a size table section include clear measurements, conversion charts, and fit guidance to help customers make informed decisions.

Let’s explore why adding a size table section is a must for any apparel brand.

• Organize size tables by product categories (e.g., shirts, pants, dresses) to help customers quickly find relevant sizing information.

A size table section gives customers a better sense of how items will fit before they buy, reducing hesitation and returns.

What Is a Size Table Section?

A size table section is a structured chart that helps customers choose the correct size by displaying:

• Measurements (chest, waist, hips, length, etc.)

• Size conversions (S, M, L, XL, EU, US, UK)

• Fit guidance (slim, regular, oversized)

• Optional model reference information

• Images to visually demonstrate sizing or fit

Size tables can include different variables, such as fabric stretch or model height, to provide more detailed sizing information.

With Easify Sections, size tables can be added as a block in the Shopify theme editor for easy customization—fully customizable inside the Shopify theme editor.

1. Reduce Returns and Refunds

Incorrect sizing is the #1 cause of returns in fashion ecommerce.

A clear, complete size table with all relevant measurements:

• Helps customers choose the right size the first time

• Sets accurate expectations

• Reduces costly returns and exchanges

Providing a complete size table further reduces the likelihood of returns by ensuring customers have all the information they need.

Fewer returns mean higher profit margins and happier customers.

2. Increase Conversion Rates

Many customers hesitate at the “Add to Cart” stage because they’re unsure about size. A well-placed size table section helps focus the customer's attention on choosing the correct size, reducing hesitation.

A visible size table:

• Removes doubt

• Speeds up decision-making

• Encourages confident purchases

Clear sizing guidance directly increases add-to-cart and checkout completion rates.

3. Build Trust and Professionalism

A detailed size table signals that your brand is:

• Transparent

• Customer-focused

• Professional and reliable

Including trust badges alongside your size table section can further reassure customers of your store's reliability.

This reassurance is especially important for first-time buyers who don’t yet know how your products fit.

4. Improve the Mobile Shopping Experience

Most fashion purchases now happen on mobile.

A mobile-optimized size table:

• Is easy to open and read

• Uses clear typography and spacing

• Avoids overwhelming the product page

• Can use a slide or carousel format on mobile, allowing customers to swipe through sizing information efficiently

Easify Sections size tables are mobile-first, ensuring smooth usability on all devices.

5. Reduce Customer Support Questions

Many customer inquiries are sizing-related:

• “Does this run small?”

• “What size should I choose?”

• “Is this oversized?”

A well-designed size table answers these questions upfront, reducing support tickets and saving time for your team.

Including a sizing FAQ section alongside your size table can further reduce customer inquiries by addressing common questions directly on the page.

6. Support International Customers

If you sell internationally, size confusion increases.

Size tables with:

• EU / US / UK conversions

• Measurements in cm and inches, with default units set based on the customer's location

…make your store accessible to a global audience and reduce friction for international shoppers.

7. Increase Customer Satisfaction and Loyalty

When customers receive clothing that fits as expected, they are:

• More satisfied

• More likely to keep the item

• More likely to buy again

Providing a size table section is a one-time investment for your store—customers can access sizing information without any recurring payments or ongoing charges.

Clear sizing builds long-term trust and repeat purchases.

8. A Lightweight Alternative to Sizing Apps

Many sizing apps:

• Slow down your store

• Add unnecessary scripts

• Require monthly subscriptions

• Reduce page speed, especially when you have many apps installed on your store

With Easify Sections, size tables are:

• Native Shopify sections

• Fast-loading

• One-time setup

• Fully editable in the theme editor

• Not dependent on installed apps, so using native sections instead of installed apps can significantly improve page speed

Best Placement for a Size Table

For maximum impact, size tables should be:

• Near the size selector

• Linked clearly (“View Size Guide”)

• Easy to access without scrolling

Additionally, consider placing the size table in a floating section or as a pop-up to ensure it remains visible and accessible at all times.

Easify Sections lets you control placement and display style effortlessly. You can easily find sections like the size table in the Shopify theme editor or section store for quick customization.
