eBay To Begin Hiding Non-Standard Size Apparel and Footwear Listings Starting in July. Be Sure To Update Your Listings Before Then!
eBay will begin hiding Apparel & Footwear listings beginning in July unless they conform to its size requirements. eBay informed developers of the change, calling it a Size Standardization.
Update: "Apparel & Footwear listings with non-standard, missing, or incomplete size information may be blocked or hidden starting July 2026. Normalization begins in June."
eBay said the size standardization for Apparel & Footwear listings on eBay was a step toward improving listing quality, buyer trust, and overall marketplace performance, and said the update would apply to listings created via APIs, File Exchange, and third-party tools. Presumably, eBay will require sellers who create their listings manually to also conform to the new standards.
"Starting from June 2026, eBay will begin automatically normalizing existing listings with high-confidence size values (e.g., "Small" → "S") and flagging low-confidence or invalid entries (e.g., "See description" or "N/A").
"Starting from July 2026, all new and existing listings with non-standard, missing size values, and/or condition values will be blocked from the site or placed on hold."
eBay said it would handle normalization of high-confidence values automatically, and flag low-confidence or invalid entries. "Starting from July 2026, all new and existing listings with non-standard, missing size values, and/or condition values will be blocked from the site or placed on hold."
