In May, Amazon removing Amazon’s generic size charts from product detail pages on Amazon.com and replacing them with brand-specific size charts.
If the seller has a Brand Registery, Amazon recommends the seller to contact Seller Support to create a brand-specific size chart for each Product Type. Brand-specific size charts provide detailed measurement information for customers to ensure a product will fit. This will improve the customer experience and help reduce size-related returns.
Note: Brand-specific size charts are only available to Brand Registered Sellers at this time and are specific to a Department (Women, Men, Boys, Girls, Baby) and Product Type (Dress, Pants, etc.).
