Zara Size Guide: What Size Am I in Zara? Fit Advice, UK Sizing Help & International Conversions

Zara is a high-street staple with global reach—but when it comes to sizing, things get confusing fast. Between frequent style drops, inconsistent fit across categories, and international sizing labels, it’s no wonder shoppers are asking: What size am I in Zara?

At Tellar.co.uk, we take the guesswork out of fashion sizing. Whether you’re shopping Zara in-store or online, we match your body measurements to the correct Zara size in seconds—for trousers, tops, dresses, jackets and more.

Why Zara Sizing Can Be So Inconsistent

Zara is part of the Inditext group and manufactures clothing across multiple regions with varying patterns and sizing templates. You might wear a Medium in one blouse and a Large in another—despite no change in your body measurements.

Common Zara sizing issues include:

Tight shoulder seams on tailored blazers
Shorter-than-average hemlines on dresses
Narrow fits through the hip in jeans and trousers
Sizing tags that differ between UK, EU, and US systems

This means the only reliable way to choose the right Zara size is to use your actual body measurements, not guess based on previous purchases.

That’s where Tellar.co.uk comes in—free, fast, and accurate every time.

Zara Size Conversion: UK, EU & US Equivalents

Zara’s internal sizing primarily follows EU standards, but labels often show multiple conversions. Here's a quick reference table for women’s clothing:

EU Size	UK Size	US Size
32	4	0
34	6	2
36	8	4
38	10	6
40	12	8
42	14	10
44	16	12

🟡 Tip: These are approximate. Fit varies significantly by cut and fabric. Always measure bust, waist, and hips to get a precise match. Better yet—use the Tellar Size Tool to skip the conversion table altogether.

What’s the Fit Like? Zara Sizing Advice by Category

1. Tops and Blouses

Zara tops often run slightly small, especially across the bust and shoulders. If you're between sizes or have a fuller chest, size up.

2. Trousers and Jeans

Zara’s trousers are designed with narrow hips and high rises. They tend to suit straight or athletic body types best. Hourglass or pear shapes should consider sizing up or opting for stretch fabrics.

3. Blazers and Coats

Zara’s outerwear sizing is inconsistent. Some oversized pieces are true to size, while tailored coats can feel restricted in the arms. If layering, choose the larger of your two potential sizes.

4. Dresses

Shorter hemlines and tighter bodices are common in Zara’s dresses. Tall shoppers may find mini dresses very short. Always check the hip measurement.

How to Measure Yourself for the Right Zara Fit

Can I Trust Zara’s “Find My Size” Feature?

Zara’s website includes a basic size estimator based on height, weight, and age—but it lacks nuance. It doesn’t consider your exact body shape or how different cuts fit differently.

Tellar.co.uk, by contrast, uses precise bust-waist-hip inputs and matches you to Zara sizing across hundreds of styles, alongside 1,500+ other brands. It’s accurate, always free, and you only need to enter your measurements once.
