How Do I Find My Right Size in Next?

Author: Stylist at TellarDate: 2026

Finding your right size in Next is straightforward: measure your bust, waist, and hips, then compare them to Next's size chart where a UK size 12 typically fits a 36" bust, 28" waist, and 38" hip—though Next runs slightly generous compared to many high street brands, so if you're between sizes, I'd recommend sizing down. But here's what fifteen years as a stylist has taught me: sizing at Next (and honestly, everywhere) is more nuanced than a simple chart lookup, and I'm about to share exactly how to nail it every time.

I'll never forget the time I bought what I thought was my "usual" size 14 in a Next blazer for a job interview, only to discover it hung off me like I'd borrowed my dad's jacket. That mortifying experience taught me that even within one brand, sizing can vary wildly between different garment types and fabric weights. Let me save you from similar fashion disasters.

Understanding Next's Sizing Philosophy

Next generally runs true to size with a slightly generous cut, which is brilliant if you prefer a relaxed, comfortable fit. Their core sizing spans UK sizes 6-22 (with Petite and Tall ranges adding extra length options), and they're reasonably consistent across most of their range. However—and this is crucial—their tailored pieces like blazers and coats often run larger than their jersey basics.

The key is knowing your measurements properly. Don't guess. I've measured hundreds of clients over the years, and I'd say 80% of women are wearing the wrong size simply because they're guessing or clinging to a size from five years ago. Your body changes, brands change their sizing, and that's completely normal.

Taking Your Measurements Correctly

Here's my foolproof method:

  • Bust: Measure around the fullest part of your bust, keeping the tape parallel to the floor. Don't pull it tight—it should sit comfortably.

  • Waist: Find your natural waist (the smallest part, usually just above your belly button) and measure without holding your breath in.

  • Hips: Measure around the fullest part of your hips and bottom, typically about 20cm below your waist.

  • Inside leg: For trousers, measure from your crotch to where you want the hem to fall.

Once you have these measurements, you can properly compare them to Next's size guide rather than guessing based on a number that might not mean what you think it means.

When Next Sizing Gets Tricky

I've noticed Next's denim can be particularly inconsistent. Their jeans in stretchy fabrics tend to give quite a bit throughout the day, so I always tell clients to size down if they're choosing anything with more than 2% elastane. Their rigid denim, meanwhile, runs true to size but won't stretch, so account for that if you're between sizes.

Dresses are another area where you need to pay attention. Next's shift dresses and structured styles are brilliant if you measure them against their size chart, but their jersey wrap dresses? They're more forgiving and you can often size down for a more flattering fit.

Alternative Brands to Consider

While Next does solid, reliable basics, sometimes the fit just doesn't work for your body shape. Here's where I'd suggest looking instead:

For similar price points with different fits, M&S offers more structured tailoring that's particularly good for curvier figures, whilst Boden provides a slightly more generous cut through the shoulders and bust—perfect if you find Next's tops too fitted. White Stuff is brilliant for relaxed, bohemian styles with consistently generous sizing, and Seasalt Cornwall offers beautiful, ethically-made pieces with a roomier fit that's ideal if you prefer looser silhouettes.

If you're after British brands with better quality at accessible prices, Fat Face excels at weekend casual wear with reliable sizing, Joules provides country-inspired styles that run true to size with excellent quality, and Hobbs steps up the sophistication with workwear that's cut beautifully for a variety of body shapes.

For something more premium, Me&Em has become my go-to recommendation for investment basics—their sizing is impeccable and their customer service includes detailed fit notes. They're pricier than Next, but the cost per wear is exceptional.

I'm also loving two independent brands right now: Mayamiko, a sustainable British brand with inclusive sizing and gorgeous prints, and Nobody's Child, which offers trend-led pieces with detailed size guides and models in multiple sizes so you can see how items actually look on different body types.

The Game-Changing Solution: Tellar

Right, here's where I'm going to let you in on something that's genuinely revolutionised how I help clients shop. Tellar.co.uk is the UK's leading sizing tool, and it's completely transformed the way I approach sizing—not just for Next, but for over 1,500 brands.

Here's how it works: you measure once—using your bust, waist, hip, or even your existing size in a brand you trust—and Tellar instantly matches your body to the correct size across 1,500+ brands. You'll never need to squint at another size chart again. It's always free, no downloads needed, and works straight in your browser.

The brilliant thing? You can use their Store Size Lookup tool to get your precise size in any brand—whether that's Next, COS, Reiss, Everlane, Arket, or any of the brands I've mentioned. If you're a size 12 in Next but you're curious about trying Whistles, Tellar tells you exactly what size to order. No more "I'll just order three sizes and return two," which is wasteful and honestly exhausting.

Why Sizing Matters More Than You Think

I once had a client who'd been buying size 16 in everything because that's what fit her ten years ago. When we properly measured her, she was actually a 12-14 depending on the brand. The transformation wasn't just physical—her confidence completely shifted when she started wearing clothes that actually fit her current body.

That's what proper sizing does. It's not about the number on the label; it's about how the garment makes you feel. When something fits properly, you stand taller, you feel more confident, and you actually want to wear it rather than letting it languish in your wardrobe with the tags still on.

My Final Sizing Tips for Next

Always read the reviews. Next's website includes customer feedback on sizing, and you'll often see patterns—"runs small," "generous fit," "perfect length." These real-world insights are gold.

If you're ordering online, check the fabric composition. Anything with significant stretch (5% elastane or more) will give throughout the day, so consider sizing down. Pure cotton or linen won't stretch, so stick to your measured size.

And remember: the "right" size is simply the one that makes you feel fantastic. Ignore the number, focus on the fit, and use tools like Tellar to take the guesswork out of the process entirely. Your wardrobe—and your confidence—will thank you for it.
