PE Nation Size Guide: What Size Am I in PE Nation? Fit Advice, UK Sizing & Performancewear Tips

PE Nation blends performance wear and streetwear like few other brands—technical activewear, fashion-forward outerwear, and bold branded essentials that take you from gym to street with ease. But if you’ve ever struggled to figure out your size in PE Nation, you’re not alone.

With Australian sizing, body-sculpting fabrics, and mixed-fit designs, it’s easy to get it wrong.

This guide explains how PE Nation sizing really works and how you can avoid costly guesswork by using Tellar.co.uk—the UK’s leading free sizing tool, trusted by thousands of shoppers for accurate, personalised recommendations across 1,500+ brands.

Does PE Nation Run Small or True to Size?

PE Nation is an Australian-based brand, but it ships internationally and uses a mix of AUS and US sizing on different platforms. Sizing inconsistencies often lead to confusion, especially for UK shoppers.

Here’s the general rule of thumb:

Leggings and shorts: Run true to size, with high-compression fit.
Sports bras and tanks: Slightly snug—consider sizing up for comfort or larger cup sizes.
Outerwear and streetwear layers: Typically true to size, occasionally oversized by design.
Tops and sweats: Streetwear silhouettes, so they lean slightly loose—but not baggy.

Because of these fabric differences, two size 10 items from PE Nation might fit very differently depending on material and product line.

Tellar.co.uk solves this by using your body measurements to give size advice by product category—not just brand.

PE Nation UK Size Conversion Chart

PE Nation (AU/US Label)	UK Size	Bust (cm)	Waist (cm)	Hips (cm)
XS (AU 6 / US 2)	UK 6	80–84	63–66	86–90
S (AU 8 / US 4)	UK 8	85–88	67–70	91–94
M (AU 10 / US 6)	UK 10	89–92	71–74	95–99
L (AU 12 / US 8)	UK 12	93–97	75–79	100–104
XL (AU 14 / US 10)	UK 14	98–103	80–85	105–110

Many UK shoppers assume AU and UK sizes are aligned, but Australian sizes tend to run smaller. A PE Nation AU 10 is closer to a UK 8–10 depending on fabric stretch and style.

Instead of converting charts manually, just enter your measurements once at Tellar.co.uk and let the system do the work.

Sizing Tips for PE Nation by Category

1. Leggings & Shorts

These are designed for high-impact training and intense workouts. They typically:

Offer medium to firm compression
Sit high on the waist
Use durable, sculpting technical fabrics

Stick to your true size for performance.

Size up if:

You’re between sizes
You prefer a more relaxed fit
You want them for all-day comfort or casual wear

2. Sports Bras & Crop Tops

PE Nation bras are supportive and stylish, but can run snug—especially if:

You have a larger cup size
You don’t like compressive fit
You plan to wear them for extended periods

If you’re a UK 34C or above, consider going up one size from your usual activewear bra size.

Tellar.co.uk factors in your underbust and bust measurements for sports bra recommendations—so you’ll avoid tight bands and awkward fits.

3. Outerwear, Jackets & Puffers

This is where PE Nation shines in versatility. Their jackets and bombers are often:

True to size in the shoulders
Slightly oversized for layering
Structured or cropped depending on collection

If you plan to wear it with bulky layers, size up. Otherwise, stick to your UK size for a clean, street-ready fit.

Expect streetwear influence here—boxy cuts, cropped lengths, and branded details. They generally run true to size or a little roomy.

Consider sizing down if:

You want a slim silhouette
You’re styling it with tailored or fitted bottoms
You’re petite and want a cleaner fit across the shoulders
