Champion Size Guide: What Size Am I in Champion? UK Fit Advice & Sizing Help

Champion has long been a staple of streetwear and sportswear culture — known for heavyweight sweatshirts, collegiate logos, and retro-inspired hoodies. But with multiple sub-labels (Champion Reverse Weave, Champion Authentic, Champion Europe) and US-to-UK size conversions to consider, it’s no surprise many shoppers are unsure what size to buy.

If you’re asking:

“Does Champion run big or small?”
“What size should I order in Champion UK vs US?”
“How does Champion fit compared to Nike or Adidas?”

You're not alone. At Tellar.co.uk, we’ve reviewed Champion’s size data across all major collections and compared it with over 1,500+ global brands. Our system gives you an instant, personalised recommendation — based on your actual body measurements, not just guesswork.

Does Champion Run Big or Small?

Champion sizing varies depending on the collection:

Collection	Fit Overview
Champion Reverse Weave	Runs large – designed for an oversized, boxy fit
Champion Authentic	True to size – more traditional streetwear fit
Champion Europe (EU)	Slightly slimmer than US sizing – size up for a looser fit
Heritage/Varsity Cuts	Generally roomy and unisex – expect a relaxed silhouette

Overall, Champion tends to run large, especially in unisex items and US-based collections. Many UK shoppers choose to size down one full size if they want a closer fit, particularly in sweatshirts, hoodies, and joggers.

Champion Size Conversion Chart (US/EU/UK)

Because Champion is originally an American brand, it uses US sizing, which can differ slightly from UK and EU equivalents.

How to Measure Yourself for Champion

Champion is known for volume — boxy sweatshirts, loose-fit joggers, and oversized tees. To find the right size:

Chest: Measure around the fullest part of your chest, under the arms
Waist: Measure around the natural waistline
Hips: (For joggers or leggings) Measure around the widest part of your bum

Use a soft tape measure, and keep it straight and snug without pulling too tight. Need one? We’ll send you a free one when you create your Tellar profile.

3. Champion Crop Tops & Women’s Tees

Closer-fitting than unisex cuts

Real Customer Feedback on Champion Fit

We’ve aggregated reviews across Champion’s UK site, ASOS, Urban Outfitters, and Zalando:

“Reverse Weave hoodies are super comfy, but they’re massive — definitely size down.”
“I’m a UK 10 and the Small was roomy but just right after one wash.”
“The joggers fit great in the legs but the waist was a bit snug. I'd go up one.”
“Love the quality, but I had to exchange for a smaller size twice.”

This confirms our data — Champion is consistent, but often large by UK standards. Oversized is intentional. If you prefer a fitted look, size down.
