Gerry Weber Sizing: Does It Come Up True to Size?

By Ella Blake – Fashion Stylist | Tellar Fashion Hub – Always honest, unbiased, & unsponsored

Gerry Weber runs slightly generous — expect to size down one size from your usual UK size for the best fit. It's one of those things I wish someone had told me before I ordered three pairs of wide-leg trousers in my usual 12, all of which could've comfortably housed both me and a medium-sized houseplant. A quick size swap to a 10 and suddenly everything clicked into place. So — let's get into the detail, because there's a bit of nuance here depending on which Gerry Weber line you're shopping.

A Quick Word on the Brand

Founded in Germany in 1973, Gerry Weber is a classic European brand that has built a strong following among women who want quality fabric, thoughtful cuts, and clothing that actually works for real life. It's not trying to be trend-led — and that's precisely the point. The brand sits in a brilliant middle ground between the high street and designer: genuinely well-made, fabric-led pieces that wash well and last. It's enormously popular in the UK, particularly among women who've outgrown the disposable fashion cycle and want something with a bit more integrity.

There are a few different lines to be aware of: the main GERRY WEBER collection, TAIFUN (their slightly sleeker, more contemporary diffusion line), and SAMOON (their plus-size range running from a UK 18 upwards). Each has slightly different sizing behaviour, which I'll get into below.

So, How Does Gerry Weber Sizing Actually Work?

As a general rule: Gerry Weber runs one size larger than standard UK sizing. If you're a UK 12, start with a Gerry Weber 10. If you're typically a 14, try the 12 first. This is particularly true for their trousers, skirts, and structured jackets — the categories where I've seen the most confusion among clients who've bought online.

The brand uses European sizing in most of their labelling (so a 38 equates to a UK 10, a 40 to a UK 12, and so on), which adds another layer of potential confusion if you're not used to converting. Here's a quick reference:

EU 36 = UK 8
EU 38 = UK 10
EU 40 = UK 12
EU 42 = UK 14
EU 44 = UK 16
EU 46 = UK 18
EU 48 = UK 20

So far so standard — but here's where Gerry Weber diverges. Their actual cut within each size tends to be on the generous side of that EU standard. The waist and hip measurements in their EU 40 often match what you'd find in a UK 14 from the high street. This isn't a flaw — it's a deliberate design choice for comfort. But it does mean a little planning before you order.

TAIFUN vs Main Line: Is There a Difference?

Yes — and it matters. The TAIFUN line tends to come up slightly more consistently with standard EU sizing, which I think reflects its slightly younger, more streamlined design aesthetic. If you're between the two collections and unsure which size to go for, TAIFUN is often the one where your standard UK-to-EU conversion holds up more reliably.

The main GERRY WEBER collection, particularly in knitwear and unstructured tops, is where I notice the most variation. Some of the more relaxed-fit styles are intentionally oversized, so it's worth checking the specific product measurements rather than relying on your converted size alone.

What About SAMOON?

SAMOON is the brand's extended size range and runs from EU 44 (UK 16) upwards. The good news is that the sizing here is generally more consistent — it's been specifically developed for that size range so the proportions tend to be better thought through. I've had clients rave about the trouser fit in particular; longer inseams and proper waist-to-hip ratios that so many mainstream brands get wrong. If this is your range, it's absolutely worth trying — the fit is genuinely excellent.

My Tips for Shopping Gerry Weber Online

Always check the brand's own measurements — they list bust, waist, and hip for each size and it's more reliable than the size label alone.
For trousers specifically, size down. Their trouser waistbands run notably generous.
Knitwear and jersey pieces can vary wildly — measure your bust against the product guide rather than assuming.
Jackets and blazers tend to have a more relaxed back and shoulder — brilliant for comfort, but consider sizing down if you want a neater, more tailored look.
If you're buying in-store, always try two sizes. The difference in how their 10 and 12 sits can be significant.

What to Buy If Gerry Weber Doesn't Quite Work for You

Gerry Weber has a very specific aesthetic — classic, European, quality-focused. If you love that sensibility but find the fit tricky, or if you just want a few comparable alternatives at different price points, here's where I'd send you:

High Street & Mid-Market

Hobbs – Arguably the closest high-street equivalent in terms of aesthetic. Well-cut classics, excellent fabric quality for the price, and consistent sizing. Their tailoring in particular gives Gerry Weber a real run for its money.
Phase Eight – Brilliant for occasion and smart-casual dressing, with a flattering fit across sizes. Their dresses and blouses especially have that same slightly elevated, grown-up feel.
Jigsaw – More contemporary, but the same commitment to fabric and wearability. Sizing tends to be pretty true to UK standard, which makes it a comfortable transition if Gerry Weber's generous cut doesn't suit your shape.
Boden – Great for the more relaxed end of the Gerry Weber customer — lovely quality, playful prints, and excellent for knitwear and casual weekend dressing.
White Stuff – Particularly good for layering pieces, linen, and relaxed-fit trousers. Shares a lot of Gerry Weber's fabric-first philosophy at a lower price point.
M&S – Worth a serious look for basics. Their Per Una and Autograph lines in particular have improved enormously and offer real value for classic, wearable pieces.
Whistles – For those who want the quality-fabric approach but with a sharper, more contemporary edge. Their tailoring is exceptional for the price point.

Premium Picks

Me&Em – A brand I recommend constantly. Beautifully made, intelligent sizing, and a genuine focus on clothes that flatter real bodies. Their trousers and knitwear are standout.
Massimo Dutti – Spanish quality at accessible luxury pricing. The fabric on their coats and trousers is genuinely excellent, and their European sizing tends to be accurate and generous in the right ways.

Two Independent Picks Worth Knowing

Chalk (chalk.fashion) – A small Sussex-based brand making beautifully simple, relaxed clothing in quality fabrics. Think linen shirts, wide-leg trousers, and easy jersey dresses — all with excellent sizing consistency. If you love Gerry Weber's no-fuss wearability, Chalk will feel like a natural fit.
Adini (adini.co.uk) – A wonderful independent British label known for its artisan prints, natural fabrics, and generous, comfortable cuts. Very much in the spirit of Gerry Weber's European fabric sensibility, but with a more bohemian, individual flair.
