Overview
- Vinted switched women’s and kids’ size categories to letter labels mapped to UK numeric ranges (for example, XS = UK 4–6, S = 8–10, M = 12–14) and applied the change to existing listings.
- Users report widespread mismatches where items now appear several sizes larger than before, prompting confusion for buyers and complaints across TikTok, Reddit and parenting forums.
- Some sellers say they are manually correcting large inventories or have placed their shops on holiday mode to avoid incorrect orders.
- Vinted has published a full size chart up to 9XL (listed as UK 52) and directed members to in‑app messages and Help Centre guidance on how to edit listing sizes.
- The company has not indicated any reversal of the rollout, and is urging members to review listings to ensure sizes are accurate under the new system.
