Finding the Right Size in Any Pair of Jeans

Finding the Right Size in Any Pair of Jeans – Without Guesswork

Get the perfect fit in every denim style, across 1,500+ brands, with Tellar.co.uk

So, you’ve found your dream jeans—maybe it’s a pair of wide-leg high-waisted trousers, or a sleek return-to-skinny silhouette. But then comes the hard part: which size should you actually buy?

Jeans are one of the hardest clothing items to get right when shopping online. Sizing varies wildly between retailers, styles, and even fabric blends. Whether they run small, stretch out after a few wears, or are tailored for specific body shapes, getting it wrong means frustration, returns, and wasted money.

That’s where Tellar.co.uk steps in.

Why Jeans Are the Most Difficult Item to Size Online

Jeans are built from structured fabrics, often with minimal stretch. They must accommodate curves, waistlines, leg lengths, and body proportions that vary from person to person. Common issues include:

A perfect waist fit, but too tight on hips
Great in the thighs, but gaping at the waist
Accurate fit when first worn, but stretch out quickly
Variation in fit based on the rise (low, mid, high)
Inconsistencies across stores—even within the same brand

No wonder it's so common to feel like one size never fits quite right.

Tellar.co.uk: Real-Time Size Matching for Every Body

Tellar.co.uk is the UK’s leading free sizing tool, helping you find the right size across 1,500+ clothing brands—including denim specialists like Levi’s, Mango, ASOS, Massimo Dutti, Zara, M&S, and more.

Instead of guessing or relying on generic charts, Tellar matches your body measurements to each brand’s official size data, in real time.

Here’s how it works:

Enter your body measurements once (chest, waist, hips)
Or, enter a size you already wear from a brand that fits you well
Select the store you want to shop from
Tellar shows your best-fitting size, adjusted for how that brand cuts its jeans
You can toggle between cm and inches, and even see if the brand runs large or small

Why Standard Size Charts Don’t Work for Jeans

Most brands publish vague, flat size charts that don’t account for:

Your body shape (e.g. curvy hips, straight figure, fuller thighs)
How the cut of the jeans affects fit (e.g. wide-leg vs skinny vs bootcut)
Vanity sizing or brand-specific adjustments
How much the fabric stretches with wear
Whether the brand uses in-between sizes or double-number sizing

Tellar goes beyond basic conversions. It uses data-driven sizing to give you the most accurate match possible, every time.

How to Measure Yourself for the Best Jeans Fit

You only need to measure three points:

Waist – At the smallest part of your natural waistline
Hips – Around the fullest part of your hips and bottom
Chest – Still useful for shirt-style denim pieces or full-body sizing

No measuring tape? You can download our free printable tape and set up your profile in minutes:

Once done, you’ll never need to repeat it. Your profile is saved securely so you can check your size in seconds across hundreds of stores.

What If You Already Know Your Size in One Shop?

Choose “I know my size in a store”
Enter M&S and Size 16
Tellar instantly estimates your measurements
Then tells you what size to buy in Zara, Reiss, ASOS, or any other brand

It’s perfect for shopping outside your usual go-to store—no tape measure needed.

Real Examples: What Tellar Reveals

Let’s say your hip measurement is 114cm and waist is 92cm:

Mango: Tends to run small in fitted jeans—Tellar recommends UK 18
M&S: More generous in the hips—UK 16 may fit better
River Island: Runs slim on the waist—UK 18 recommended
Zara: Often tighter through the thigh—UK 20 for comfort

You’d never know this just from browsing or using standard size charts.
