No. Sweaty Betty’s leggings are known to offer a precise fit based on their standard width and length. They don’t run small or tend to overstretch. From personal experience, I can tell you their leggings are true to size.

Does Sweaty Betty have a size guide?

Yes, Sweaty Betty does have a detailed size guide that also explains how to measure yourself for the perfect fit.

Sweaty Betty’s leggings usually range between XXS (UK 6) to XXL (UK 18-20). But what I like about Sweaty Betty’s leggings is that they come in three leg lengths: ⅞ length, cropped, and full length. So if you’re 5’4 and under, you should pick the ⅞ length as they are full size on you. Their cropped leg length runs 17″ or 50 cm, while the full length is 27″ or 68 cm. You can also take their leggings quiz to find the type of leggings that suit you best.

Their trousers have different leg lengths, too. Most of their styles come in full leg lengths, but some, like their Explorer Trousers, come in 25″ and 27″ inseam.

Sweaty Betty’s sports bras offer a snug and supportive feel, so your best bet is to stick with your usual cup size. They offer a wide range of sizes between cups A to F. Plus, they offer three support levels – light, medium, and high – that suit every physical activity you go for. You can check out their bra quiz to see which Sweaty Betty bra suits you best. 

Tips on getting the right measure for Sweaty Betty

Getting your Sweaty Betty size spot-on is all about the details. Before you start, grab your trusty tape measure and maybe a friend to help ensure everything’s precise.

1. Starting with the Basics: First things first, to get the most true-to-you measurements, it’s best to be in your underwear. This way, you’re getting the real deal without any extra fabric adding inches.
2. Chest: For your chest, loop the tape around the fullest part, but keep it snug, not tight. You want it firm around your armpits and shoulder blades but still comfy.
3. Waist: When it comes to your waist, find that sweet spot just below your natural waistline (that’s where you naturally bend side to side). Let the tape hug your waist, but slip a finger in between – this isn’t a squeeze test!
4. Hip: Hips can be tricky, but here’s the secret – wrap the tape around the widest part and again, let a finger slide in between. It’s all about that ‘fits just right’ feeling.
5. Inseam: Got a pair of pants that fit like a dream? Use them as your guide. Measure from the crotch seam straight down to the bottom of the hem.
