The 2026 Guide to European Brand Sizing for US Shoppers
Shopping H&M, Zara, or Mango from the US? European sizing is a completely different system, and getting it wrong is extremely easy. This guide gives you the exact conversion rules for the most popular European brands.
Sizing at a glance
H&M runs small, especially in European sizing. Size up one from your usual. Basics and jersey pieces are more forgiving; structured and denim pieces run the smallest.
European tailoring, typically runs small, size up
Mango runs small, especially in structured pieces. Size up one for comfort.

Build My Fit ProfileThe European Sizing System
European clothing sizes are based on the metric system and reflect body measurements in centimeters. Unlike US sizes (which are largely arbitrary labels), European sizes have a logical foundation, but that does not make them easier to use if you are accustomed to US sizing.
The key insight: European sizes are not just "one number off." The gap between US and European sizing varies by brand, by country of origin, and by garment category. A Zara XS is not the same as an H&M XS, even though both are European brands.

| S (4–6) | 36–38 | 84–88 | 66–70 | 91–95 |
| M (8–10) | 40–42 | 90–94 | 72–76 | 97–101 |
| L (12–14) | 44–46 | 96–100 | 78–82 | 103–107 |

How to use this table: Measure your chest, waist, and hips in centimeters. Find the row that fits all three (or prioritize the measurement most relevant to the garment). Then apply the brand-specific adjustment below.
Brand-by-Brand Rules
Zara
Overall tendency: Runs 1–2 sizes small.
Zara is the strictest European brand for US shoppers. Their Spanish sizing is based on a narrow cut that does not accommodate American body proportions, particularly in the shoulders, thighs, and bust.
Zara publishes exact centimeter measurements on every product page. Use those, not the letter sizing.

Overall tendency: True to size, with exceptions.
H&M is the most consistent of the three for US shoppers. Their sizing has been adapted for a global market, and they use a wider cut for most garments than Zara.

Mango
Overall tendency: Runs small, similar to Zara but less extreme.
Mango is a Spanish brand like Zara, but their sizing has been slightly adjusted for international markets over the years. They still run small, but less dramatically than Zara.

Your 3-Step Strategy for Shopping European Brands
Step 1: Get your measurements. You need chest, waist, and hips in centimeters. Measure yourself or use measurements from a garment that fits perfectly.
Step 2: Apply the brand rule. Use the brand-specific guidance above to determine whether to add 2–4cm to your measurement before checking the brand size chart.
Step 3: Read the garment measurements, not the size label. Every reputable European brand publishes exact centimeter measurements for each item. Trust the numbers, not the letters.
The more you shop European brands, the more intuitive this becomes. Your US size stops being a useful reference, your measurements take over, which is actually a better system.
Stop guessing. Build your profile once.
Never check a size chart again. Your fit profile knows your exact size across every brand we cover.
