For most fashion brands, getting apparel sizing right is a constant challenge.

Even when brands collect measurements across product lines, the data is often inconsistent, outdated, or scattered across spreadsheets. Translating all that sizing data into a smooth, accurate experience for online shoppers can feel impossible.

That’s where TrueToForm steps in.

We’re not just a sizing software provider - we’re your full-service apparel sizing partner, helping you audit, organize, and transform your Shopify size charts (or those on any eCommerce platform) into interactive, visual guidance your customers will trust.

Why Apparel Sizing Is So Hard to Get Right

Most fashion brands rely on legacy systems or manual processes to manage sizing. Over time, this leads to confusion and inconsistency between collections, and even within a single product line.

Common pain points include:

• Disorganized spreadsheets and measurement files
• Duplicate or outdated size charts in Shopify
• Lack of visibility into which size chart applies to which product
• Disconnects between product data and customer-facing guidance

The result? Higher return rates and lower customer confidence.

When shoppers aren’t sure what size to buy, they hesitate - or buy multiple sizes and return half.

How TrueToForm Brings Clarity to Your Sizing Data

At TrueToForm, we make it simple to take control of your apparel sizing - from messy data to a clear, conversion-driving strategy.

Step 1: Audit Your Sizing Data

We start by auditing your current sizing data: everything from your garment specs to size chart variations. Our team identifies inconsistencies and helps you establish a clean, standardized foundation for your sizing system.

Step 2: Organize It in Shopify (or Your Platform of Choice)

Once your sizing data is clean, we help you organize and connect it directly to your product listings.

For Shopify brands, that means building a Shopify size chart system that’s easy to manage, scalable across collections, and consistent across every product page.

Step 3: Translate It into Visual Size Guidance

Finally, we bring your data to life.

Our visual sizing experience uses AI to turn your Shopify size chart into an intuitive fit prediction interface, helping customers instantly find their best size without taking manual measurements.

The result: fewer returns, higher conversion rates, and a more confident shopping experience.

Real Results: How Clean Sizing Data Improves Performance

When one DTC brand partnered with TrueToForm, they were juggling multiple conflicting size charts.

After auditing and organizing their sizing data, we implemented our visual size prediction tool and saw a 4.5x lift in conversion for widget users, all without changing their products or fit.

Better apparel sizing doesn’t just improve operations; it creates measurable business impact.
