What’s My Clothes Size at Next? Does Next Run Big or Small?

If you’ve ever been unsure about your sizing at Next, you’re not alone. Known for its broad size ranges and popular across all age groups in the UK, Next clothing is often praised for consistency—yet some shoppers still find variations depending on the garment type, fit, or even collection. So, does Next run big or small? And how can you find your exact size in real time, without returning half your order?

This post answers those questions and introduces a free solution from Tellar.co.uk, the UK’s leading sizing tool.

Does Next Run Big or Small?

Generally speaking, Next runs true to size, particularly compared to UK high street norms. However, there are exceptions by category and fit:

Key Fit Insights:

Tops, dresses and knitwear tend to fit true to size or very slightly large
Trousers and jeans can be snug around the waist and hips depending on cut
Petite and Tall ranges follow a different block fit entirely
Menswear is consistent in sizing but may vary by cut (e.g. slim fit vs. regular)

Unlike brands like Zara or H&M, Next designs primarily for the UK market, using UK-specific fit models. This gives it a small edge in predictability—but variation still exists based on fabric type, cut, and collection.

Why Sizing Still Varies at Next

Even within a consistent brand like Next, several technical factors influence how clothing fits:

1. Collection-Based Fit Changes

Next has seasonal designer collaborations, maternity, petite, tall, and curve ranges. Each uses a slightly different grading scale and fit block.

2. Fabric Composition

Garments with elastane or stretch cotton tend to run more forgiving, while rigid denim or structured tailoring can feel tighter.

3. Global Sizing Pressure

As Next expands its international sales footprint, some product lines aim for a more universal fit—which can conflict with UK expectations.

4. Evolving Grading Systems

With fast-changing fashion cycles, even legacy retailers like Next adjust grading curves periodically. A size 12 from 2019 may not be identical to the same label today.

Common Fit Feedback by Category

Clothing Type	Fit Observation	Sizing Advice
Knitwear	True to size	Stick with your usual size
Tailored dresses	Slightly fitted	May need to size up if curvy
Jeans & trousers	Varies by cut	Check hip vs. waist fit
Maternity wear	True to size	Based on pre-pregnancy size
Petite / Tall lines	Adjusted proportions	Fit block tailored to height
Men’s slim fit	Runs tighter	Size up if broad-shouldered

The Limitations of Standard Size Charts

Next provides standardised size guides online, but these assume symmetrical body proportions and don’t reflect real-world shape variation. The same size 12 can fit completely differently depending on your:

Hip-to-waist ratio
Bust fullness
Height and torso length
Shoulder width

Many shoppers end up guessing, ordering two or three sizes “just in case”—especially when buying online.

That’s where Tellar.co.uk steps in.

✅ Covers Over 1,500 Brands

✅ Based on Actual Data

Tellar’s engine doesn’t guess—it reads actual size charts, block shapes and measurement logic to recommend the best size for your individual body.

Example: A UK Size 12 Shopper

Let’s say your actual body measurements are:

Bust: 94cm
Waist: 76cm
Hips: 102cm

Tellar might suggest:

Next knit jumper: Size 12
Next fitted dress: Size 14
Next high-rise jeans: Size 14, depending on stretch

Every size recommendation is calculated using your largest relevant body area for the garment type—so dresses favour hip measurements, while tops focus more on bust or shoulder width.

Why Guessing Your Size Doesn’t Work

Traditional online shopping methods involve:

Comparing yourself to a generalised chart
Ordering multiple sizes
Returning what doesn’t fit

This wastes time, increases emissions from returns, and leads to frustration. Even Next’s generous return policy doesn’t solve the core issue: sizing guesswork.

Tellar removes all of that. Once you’ve set up your profile, every brand—including Next—is matched against your measurements instantly.

Tellar Is Not Just for Next

Although Tellar is incredibly useful for Next shoppers, its database includes nearly every major UK high street and designer label, including:

Zara
ASOS
Mango
Reiss
White Stuff
Massimo Dutti
H&M
COS
…and over 1,500 more.

Whether you’re buying jeans, swimwear, maternity pieces or shirts, Tellar calculates the exact size you need—and explains why.

Final Thoughts

Next generally runs true to size, but that doesn’t mean you should rely on the label alone. With small variations across fits and fabrics, the safest and smartest way to shop is to match your exact body measurements to the garments you want to buy.

Tellar.co.uk makes that process simple, free and instant.
