Zara size guide
Zara uses EU sizing and generally runs small — especially in fitted trousers, blazers and dresses. Which collection an item belongs to changes how much it runs small by.
The three collection lines
| Line | Symbol on label | Fit |
|---|---|---|
| TRF (junior line) | Triangle | Runs smallest and narrowest |
| Basic | Square | Closest to true to size |
| Woman | Circle | Fits true to size or slightly generous |
Where sizing runs smallest
The tightest fit is consistently reported in structured, fitted pieces: trousers and jeans (especially high-rise or rigid denim), blazers and coats through the shoulder and chest, and fitted tops and dresses. Knitwear, stretch basics and oversized styles tend to run closer to true size or even generous.
