Does H&M sizing run small or large, and how it compares to Zara sizing

Does H&M Run Small or Large?

According to Tellar’s in-depth analysis, H&M generally runs on the smaller side, especially in womenswear—even though label sizes may visually seem larger due to vanity sizing

Women’s Clothing

Jeans, trousers, fitted dresses usually run at least one full size smaller than comparable high‑street brands

Tops and blouses are often narrow in the shoulders and bust—especially in the Divided line, which skews petite

Outerwear and Oversized Cuts

Looser pieces like coats, trench jackets, and puffers tend to run more true to size or slightly generous

Men’s Clothing

Generally closer to standard UK sizing but with a slimmer European fit, especially around the chest, sleeves, and trousers

Kidswear

Size labels are height-based but pieces are often narrow—even “correct” sized items can feel tight

H&M vs Zara: A Side-by-Side Comparison

Tellar compared chest, waist, and hip measurements for size 12 across high-street retailers

tellar.co.uk

H&M size 12 measures roughly 96 cm bust / 78 cm waist / 102 cm hips
Zara size 12 skews leaner at 92 cm / 74 cm / 98 cm
→ You’re looking at a 4 cm difference, meaning H&M fits more generously than Zara

Tellar also confirms:

Zara runs small, particularly in trousers, skirts, and tailored jackets—often requiring shoppers to size up 1–2 sizes

H&M runs larger relative to Zara, though still small compared to market norms

In summary:

If you're a UK 10 in Zara, you'd likely be a UK 12 in H&M—someone needing an EU 38 at Zara may be an EU 40 at H&M

Real Data: Size Differences & Consumer Trends

H&M: 64% of consumers find their usual size fits "too baggy"—indicative of overall larger fit relative to brands like Zara

Zara: 78% of users reported needing to size up in tailored styles and trousers

🧭 Why This Matters (and How to Shop Smart)

1. Vanity sizing creates illusion

H&M may label a garment size 12—but the true garment measurement aligns more with size 14 elsewhere

2. Regional sizing variants

Both Zara and H&M mix EU, UK, and US labeling—creating confusion. H&M labels might match styles better than discrepancies in Zara's EU system

3. Collection-based fit differences

H&M’s Divided line is notably more petite than its Conscious or Basics collections

Zara maintains a slim European silhouette uniformly across collections
