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

Joules is a quintessentially British brand known for its countryside charm, vibrant prints, and feel-good casualwear. From raincoats and gilets to jersey dresses, rugby tops and wellies, Joules blends practicality with playful style. But for shoppers browsing online, one question still lingers:

Does Joules run big or small?

And how can you make sure you order the right size, first time?

This guide breaks down how Joules sizing really works—and introduces Tellar.co.uk, the UK’s most accurate free sizing tool that calculates your correct Joules size in real time, based on your body shape and the garment structure.

Does Joules Run Big or Small?

Joules generally runs true to size, but certain categories can feel generous or snug, depending on the fabric and cut.

Fit observations:

Jersey tunics, sweatshirts and tops are usually relaxed and may feel roomy
Tailored dresses, shirts and slim trousers can feel snug at the bust or hips
Outerwear and waterproof coats are designed to be worn over layers and run slightly large
Padded gilets and fleeces often come with extra room for comfort

If you’re between sizes or prefer a neater fit, size down in knitwear and relaxed tops, and size up for tailored or woven items with no stretch.

What Affects Joules Sizing?

1. Practicality-First Design

Joules pieces are built for layering, comfort, and movement—which often leads to:

Slightly relaxed shoulders
Boxy fits in sweatshirts and outerwear
Generous cuts in tees and tunics

2. Fabric Behaviour

Joules uses a wide range of materials:

Stretch cotton jersey – soft and forgiving
Poplin and denim – more structured and may feel snug
Soft fleece, wool blend, or sherpa – bulky and oversized
Waterproof outerwear – designed for movement and layering

3. Style Versatility

Some Joules styles (like their Harbour tops) are cut roomy for comfort, while fitted dresses or blazers are more precise. That’s why cut and fabric matter as much as the number on the tag.

This is helpful—but it doesn’t explain:

Which styles are cut oversized vs. fitted
Which area (bust, waist, hip) determines fit
How your unique proportions affect the size outcome

That’s where Tellar.co.uk comes in.

Final Thoughts

Joules runs true to size overall, but leans generous in tops, coats and knitwear—and slightly snug in woven dresses and fitted trousers. The right fit depends heavily on fabric and design, so relying solely on a chart often leads to guesswork or returns.

Tellar.co.uk eliminates that uncertainty by giving you real-time, shape-based sizing that reflects the exact garment you’re buying. It’s fast, accurate—and completely free.
