Overview

Amazon has introduced a self‑service size‑chart builder that is now available only to sellers who are part of the Brand Registry. The feature lets brands create, edit and attach sizing tables to their listings without opening support tickets, a change that directly affects anyone selling apparel, shoes or accessories on the marketplace.

Key Points

• Self‑service creation — Brands can design a full size chart inside Seller Central, eliminating the need to submit a case to Amazon support.
• Bulk deployment — One chart can be assigned to as many as 1,000 ASINs that share the same product type, so a single effort updates an entire clothing line.
• Template library — After a chart is saved, it appears in a reusable template list, allowing new products to inherit the same layout with a single click.
• AI‑driven validation — Real‑time suggestions highlight mismatched measurement units, missing size entries or formatting errors before the chart is published.
• Relevance checks — The system automatically verifies that the chart matches the selected category (e.g., shoes versus shirts) and blocks mismatched assignments.
• Brand‑only access — Only sellers enrolled in Amazon Brand Registry see the “Size Charts” option; no extra opt‑in process is required.

How the Size Chart Tool Works

1. Navigate to Size Charts — From the “Catalog” dropdown in Seller Central, click the new “Size Charts” link to open the builder interface.
2. Define chart structure — Choose measurement units (inches or centimeters), add size rows (XS, S, M, etc.), and map each row to specific product attributes such as chest width or sole length; for example, a shoe chart might list “7 US = 25 cm”.
3. AI refinement prompts — As you fill in values, the tool flags issues like a missing “Waist” column for pants or mixed unit usage, prompting you to correct them before saving.
4. Save as template — Once the chart passes validation, you can store it as a template named “Men’s Casual Shirts – Spring 2024” for future reuse.
