Size Guide

OVERVIEW

What is this field?

The Size Guide field provides structured sizing information that helps customers select the correct size. This goes beyond simply listing available sizes — it includes measurement data, size system references, and fit guidance.

A size guide should not be stored as a single image. Structured size data enables filtering, comparison, AI-driven size recommendations, and accessibility.

Effective size guides reduce returns, increase conversion, and build customer confidence.

BUSINESS VALUE

• Sizing issues account for the largest share of fashion returns in e-commerce

• International customers need size equivalents across different systems (US, UK, EU)

• Accessible size data supports screen readers and assistive technology

• Product comparison and filtering tools rely on structured sizing information

• Accurate size data reduces customer service inquiries about fit and sizing

STRUCTURING GUIDANCE

How to structure the values

Store size data in a structured format (JSON or a dedicated size chart metafield), not as freeform text or an image-only reference.

Include body measurements (chest, waist, hip, inseam) in centimeters and/or inches, mapped to each size label.

Provide size equivalents across relevant systems: US, UK, EU.

Include garment-specific measurements when available: sleeve length, shoulder width, total length, and rise.

Note any size anomalies: “This style runs one size small; consider sizing up.”

USAGE CONTEXT

When to use this field

• Every apparel product should have size guide data

• Footwear with international size conversions

• Accessories where sizing applies (rings, hats, belts, gloves)

RECOMMENDATIONS

Best practices

• Store size data in a structured, machine-readable format — not only as an image

• Include both body measurements and garment measurements where available

• Map sizes across multiple international systems relevant to your customer base

• Add a fit note field for items that run notably large or small

• Keep size guides updated when patterns or suppliers change

• Link size guide data at the product level, not just at the category level

AVOID THESE

Common mistakes

• Uploading a size chart as an image without any underlying structured data

• Using generic category-level size charts instead of product-specific measurements

• Providing sizes in only one regional system

• Not including body measurements alongside size labels

• Storing size data as freeform text that cannot be parsed or filtered

• Ignoring that different garment types need different measurement points
