What Size Am I in Next? The Ultimate Guide to Next Clothing Sizing

Know your fit before you shop – match your size to Next and 1,500+ brands with Tellar.co.uk


Next is a staple of UK fashion — reliable, accessible, and known for offering everything from casualwear to workwear. But when it comes to sizing, even loyal shoppers often ask:

👉 Do Next clothes run big or small?

👉 What’s my exact size in Next trousers, tops, or dresses?

At Tellar.co.uk, we help you find your true size in Next based on your real body measurements, not guesswork.


Is Next True to Size?

Generally, Next clothing runs slightly generous compared to trend-led brands like Zara or Mango. Here’s how it typically fits:

  • Womenswear: Often true to size or roomy, especially in blouses and tops

  • Menswear: Consistent fit across shirts and trousers — though formal cuts may run snug

  • Children’s clothing: Runs close to standard UK sizing

  • Shoes: Accurate fit but limited half sizes in some styles

However, some product lines (e.g. linen, fitted tailoring, or petite) can differ — which is why Tellar.co.uk doesn’t rely on general rules. It calculates your best size per garment category.

Skip the size chart confusion. Use the free tool at Tellar.co.uk/store-size-lookup by entering:

  • Your chest, waist, and hip measurements

  • Your preferred units (cm or inches)

🎯 We’ll instantly tell you your best-fitting Next size, and how it compares to brands like Zara, H&M, Mango, ASOS and more.

Real Example: What Size Would You Be in Next?

If your measurements are:

  • Chest: 90cm

  • Waist: 72cm

  • Hips: 98cm

You might typically wear a UK 10 — but in Next, you could be comfortably suited to a UK 8 or 10, depending on the cut. Our tool ensures you get the best fit without needing to size up or down manually.

Never second-guess your size again — Tellar.co.uk helps you find your perfect M&S fit in seconds.


Marks & Spencer (M&S) has long been trusted for quality, comfort, and consistency — but even loyal M&S shoppers can find themselves confused when it comes to sizing. Whether you’re buying jeans, bras, or blazers, the question is the same:

👉 Do M&S clothes run big or small?

👉 What size should I buy at M&S if I wear a 12 in Zara?

At Tellar.co.uk, we take the guesswork out of clothing sizes by matching your exact body measurements to 1,500+ brands, including M&S. Best of all? It’s completely free.


How Does M&S Sizing Compare to Other Brands?

Generally, M&S sizing is generous, especially compared to high street brands like Zara or Mango. Here’s how it typically runs:

  • Womenswear: Comfortable, true-to-size fits — occasionally roomy in casualwear and loungewear

  • Menswear: Classic UK sizing, often more relaxed in trousers and shirts

  • Lingerie: One of the most accurate and comprehensive size ranges available on the UK high street

  • Shoes: Reliable sizing, with a good range of widths

But even within M&S, fit can vary by collection. That’s why Tellar.co.uk doesn’t just show you a number — it shows you the right size for the specific cut, fit, and garment type.
