Size Guide
Zerano standardizes many supplier size labels so product pages and filters are easier to use. Clothing may appear as international sizes such as XS, S, M, and L; shoes usually remain in EU numeric sizes; denim may use waist/inseam labels such as W30 L32; belts may use centimeters.
Use the guide below to understand how these display labels relate to common IT, EU, FR, UK, US, waist, and belt systems. Brand sizing may still vary by style, fabric, and fit.
Zerano Size Labels at a Glance
The size shown on product pages and filters is the Zerano display label for that product family. Some categories still use numeric, waist, denim, or EU shoe sizes when those are the clearest customer-facing labels.
| Product family | What Zerano shows | Examples |
|---|---|---|
| Women clothing, dresses, tops, jumpsuits | Alpha sizes | IT 40, EU 36, FR 36, UK 8, US 4 may display as S |
| Women bottoms | Alpha sizes or denim waist labels | IT 42 may display as M; jeans may display as W28 |
| Women shoes | EU numeric sizes | 38, 38.5, 40, 40.5 |
| Belts | Centimeters or alpha sizes | 85CM displays as 85 cm; some belts may use S, M, L |

Composite and Supplier-Specific Labels
Some supplier labels contain two size references. Zerano may use those references to make a product discoverable through more than one clean filter, while cleaning the raw supplier formatting before display.
| Supplier label | Zerano display | Filter discoverability |
|---|---|---|
| 34/32 on a women dress | XS / 32 or XS | Appears under XS |
| 38/32 on a women dress | M / 32 or M | Appears under M |
| 46_30 on men trousers | 46 / 30 | Appears under Numeric 46 and Waist 30 |
| 52_36 on men trousers | 52 / 36 | Appears under Numeric 52 and Waist 36 |
| 52 (XL) | 52 / XL | Appears under 52 and/or XL where appropriate |
