H&M Sizing: Does It Run Big or Small? A Stylist's Complete Guide

H&M sizing generally runs smaller than expected, particularly for bottoms where you'll typically need to size up by 1-2 sizes, whilst tops tend to be more true to size or even slightly larger depending on the style. As someone who's spent years navigating the quirks of high street sizing, I can tell you that H&M's inconsistency has frustrated many of us - but once you crack the code, there are some absolute gems to be found.

The Swedish retailer has undergone several sizing overhauls in recent years, but the reality remains that their fits vary dramatically depending on what you're buying. After years of styling clients and countless fitting room sessions, I've developed a foolproof approach to H&M shopping that'll save you time, money, and the inevitable sizing disappointment.

The H&M Sizing Reality Check

Let's be honest - H&M sizing is all over the shop. Whilst they've improved from the notoriously tiny sizing of a decade ago, there's still significant inconsistency across their ranges. Here's what I've learned works:

Bottoms consistently run small. Their jeans, trousers, skirts, and shorts typically fit 1-2 sizes smaller than your usual size. If you're normally a size 12, expect to need a 14 or even 16 in H&M bottoms. This isn't vanity sizing gone wrong - it's simply how their European cuts translate.

Tops are more forgiving. T-shirts, blouses, and knitwear tend to be closer to true to size, though anything marked as "oversized" or "relaxed" will genuinely be larger. Their basic tees are particularly reliable once you know your size.

Dresses vary wildly. Fitted styles run small, whilst anything flowy or described as "resort wear" tends to be generously sized. Always check the fabric composition - anything without stretch requires careful consideration.

My Professional Styling Strategy

After years of working with H&M pieces for clients, here's my foolproof approach: Always order two sizes when shopping online - your usual size and one up. This might seem excessive, but H&M's generous return policy makes it worthwhile, and you'll save multiple trips to the shop.

For in-store shopping, head straight to the fitting rooms. H&M's lighting isn't the most flattering, but it's the only way to truly gauge fit. Pay particular attention to how pieces feel when you sit down - H&M's cuts can be unforgiving around the waist and hips.

The Divided Dilemma

H&M's Divided range, aimed at younger shoppers, runs even smaller than their main line. I regularly see clients who need to go up two full sizes in Divided pieces. The styles are bang on-trend, but the sizing requires serious adjustment expectations.

Best H&M Pieces Worth the Sizing Hassle

Despite the sizing inconsistencies, certain H&M pieces consistently deliver excellent value. Their blazers, particularly in the premium line, often rival pieces costing three times the price. The trick is knowing which size to buy.

Their basic white shirts are wardrobe workhorses - once you've cracked your size, you can confidently reorder in different colours. Similarly, their knitwear, particularly merino pieces, offer exceptional quality for the price point.

The Smart Shopping Approach

My final advice? Don't let H&M's sizing inconsistencies put you off entirely. Some of my clients' most complimented pieces come from H&M - you just need to be strategic about shopping there. Focus on their strengths: trend-led pieces, basic tees, and statement accessories where sizing matters less.

For anything fitted or structured, always size up and consider the return journey part of the shopping experience. The savings on trend pieces often justify the extra effort, particularly for younger clients building their professional wardrobes on a budget.
