Does Zara Run True to Size? Here’s the Definitive Sizing Guide

Zara’s fashion-forward appeal comes with a well-known drawback: sizing inconsistency. To avoid guesswork, here’s our technical breakdown of Zara’s fit—illuminated by data, fit principles, and Tellar recommendations.

1. Why Zara Sizing Varies so Much

Zara, part of the Inditex group, creates clothes globally—from Spain, Turkey, and Asia—using multiple pattern standards. Their styles range from slim tailoring to oversized streetwear, which contributes to unpredictable sizing. A single season may include tight crop tops alongside loose kaftans—each cut uniquely

2. Zara’s Fit Profile: Small in All the Subtle Ways

According to Tellar:

Tops & Dresses: Typically run slightly small, particularly around the bust and shoulders. Many Zara styles are cut with a slim contour, which makes fit tight for curvier shapes

3. Zara EU-UK Conversions: A Quick Reality Check

Zara uses EU sizing by default, which translates like this:

EU	UK	US
34	6	2
36	8	4
38	10	6
40	12	8

But fabric choices, cuts, and inconsistent grading mean a UK-size-10 Zara dress might feel more like an 8. That’s why conversions alone aren’t enough—fit precision is key

4. How Zara Compares to Other High-Street Brands

Customer data shows:

Zara sizes are typically ½ to 1 size smaller than ASOS in similar items

Compared to Mango, Zara tops and dresses can be roomier in bust and hips, but ultimately cuts may vary widely across categories

Bottom line: Zara sizing isn’t universally small or large—it depends on category and style.

5. Do These Categories Run Small or True to Size?

Slim-fit T-shirts: Slightly snug—size up if bust-full.
Structured blazers/jackets: Tight across shoulders—size up if you plan layering.
Sleeve length & coat shoulders: Often narrow—use clothing measurements to match your dimensions.
Stretch basics: More forgiving—may fit true to size or even run large
