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)
- Products with extended or non-standard sizing
- Any product where incorrect sizing commonly leads to returns

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
