Leggings are one of the few things you buy almost entirely on feel, and "they feel fine" in the fitting room doesn't always survive a squat, a long day or the first wash. A pair that fits properly stays put, stays opaque and stays comfortable from the first rep to the walk home.
Here's how leggings should fit, the signs a pair is too tight or too big, and how to pick the right size the first time.
The quick version
- Snug everywhere, tight nowhere. They should feel like a second skin, with no spot that pinches, digs or leaves deep marks.
- The waistband lies flat at your natural waist and stays there when you bend.
- No sagging at the knees, seat or crotch, and no wrinkles bunching behind the knee.
- Opaque when you squat. If the fabric goes see-through when stretched, they're too small or too thin.
How tight should leggings be?
Tighter than trousers, but never uncomfortable. A good test: you should be able to squat, lunge and sit cross-legged without the fabric pulling, and you shouldn't feel relief when you take them off. If you're counting down the minutes until you can peel them off, they're too small.
How firm "snug" feels depends on the type of legging:
- Everyday leggings should feel soft and held, with easy movement. Think comfortable enough to wear all day. Our Everyday High-Waist Leggings are cut this way, in a four-way-stretch nylon-spandex knit.
- Compression leggings are meant to feel firmer, like a gentle, even hug through the leg and midsection. Firm is fine; numb, tingling or red marks are not. Our Compression High-Waist Leggings use a denser 80% nylon, 20% elastane knit.
- Tummy-control leggings add a smoothing front panel. It should flatten without digging in or rolling at the top. More on that in our tummy-control leggings guide.

Signs your leggings are too small
- The waistband digs in or creates a "muffin top" ridge. A band that's too small also tends to get pushed down, which is one of the main reasons leggings roll down.
- They go see-through when you bend. Over-stretched fabric thins out and shows skin or underwear. Try the squat-proof test before you wear a new pair to the gym.
- The fabric looks shiny or strained across the thighs and seat, and the colour looks lighter there than on the calf.
- A visible line forms at the crotch. Tension pulls the fabric into the seam. Here are tips to avoid camel toe, most of which come back to fit.
- Deep marks at the waist or behind the knee when you take them off, or seams twisting around your leg.
Signs your leggings are too big
- Bagging at the knees and ankles, or fabric that wrinkles when you stand still.
- The crotch sits low and you keep hitching them up.
- The waistband gapes at the back when you sit or bend.
- They slide down when you walk, even though the band isn't tight.
A pair that's a little too big is more comfortable than one that's too small, but it won't hold its shape through a workout, and loose fabric bunches and rubs.
Where should high-waisted leggings sit?
At your natural waist, the narrowest part of your torso, usually just above the navel. That's where a waistband has something to grip. A wide band, around four to five inches, spreads the pressure so nothing digs in. If a "high-rise" pair lands on your hip, the rise is too short for your torso; if it folds over at the ribs, it's too long.
How long should leggings be?
Full-length leggings should end at the ankle bone without bunching. A 7/8 length, like our Shine Liquid Leggings 7/8, is meant to sit just above the ankle. A little stacking at the ankle is fine on tall-sock days; lots of wrinkles usually means the pair is too long or too big overall.
How to choose the right size
- Measure your hips, around the fullest part of your hips and seat, with your feet together. For leggings, hips matter more than waist, because the waistband stretches more than the leg does.
- Check the size chart. Ours runs S (US 2–4), M (US 4–6), L (US 6–8) and XL (US 8–10). The full size chart shows how to measure.
- Between sizes? Size up for a softer, relaxed feel; stay in the smaller size if you want a more compressive one.
- Do the at-home test. Squat in front of a mirror, lunge, sit down and climb a few stairs. Check the waistband, the knees and the seat in good light.

Quick answers
Will tight leggings stretch out? A little, in the first few wears, but quality nylon-spandex is made to spring back. Don't buy a size down expecting it to loosen; it usually just goes see-through.
Should leggings be tight around the ankles? Snug, not gripping. If the hem leaves a mark or pulls up when you bend your knee, the pair is too short or too small.
Is it normal for compression leggings to feel hard to pull on? Yes, a bit of effort is normal. Once they're on, they should feel firm but comfortable, never painful.
What if my size is between S and M on the chart? Go by your hips, then decide by feel: M for a relaxed fit, S for a more held-in one. You can also email us your measurements and we'll tell you which to order.
