A leggings size chart maps your actual body measurements — waist, hips, inseam — to a labeled size so you stop guessing between a Medium and a Large. Here's everything you need to measure right and size right, the first time.
Why Leggings Sizing Is Never Just a Number
She orders a Medium based on her usual size, pulls them on, and immediately knows something's off — the waistband rolls, the fabric pulls across the hips, or the inseam hits at exactly the wrong length. Sound familiar? Legging sizing is one of the most consistently frustrating parts of shopping activewear, especially online.
A leggings size chart is a standardized measurement guide that maps specific body dimensions — waist circumference, hip circumference, and sometimes inseam length — to a labeled size like XS, S, M, L, or XL. The challenge is that no two brands use identical sizing. According to SELF Magazine, sizing inconsistency across activewear brands is the leading reason women return workout clothes online, with fit issues accounting for nearly one in three returns. Knowing your measurements removes that uncertainty entirely.
That's why your "usual size" matters less than your actual numbers. A tape measure and two minutes is all it takes. Once you know your waist and hip measurements, sizing into running leggings — or any style in the Glossy lineup — becomes an exact decision instead of a guess.
How to Measure Yourself for Leggings
Two measurements cover 95% of legging sizing decisions. A third — inseam — matters when you're deciding between full-length, cropped, or tall options. Here's how to take each one correctly.
- Waist circumference — Measure at the narrowest point of your natural waist, typically 1–2 inches above your belly button. Keep the tape parallel to the floor and relaxed — not pulled tight, not loose enough to slide. This measurement determines where a high-waist legging will sit and whether the waistband compresses comfortably or digs in at the sides.
- Hip circumference — Stand with feet together and wrap the tape around the fullest part of your hips and seat, usually 7–9 inches below the natural waist. This is the measurement that drives fit through the thigh. Get it wrong and nothing else matters — a legging that's too small at the hip will feel restrictive regardless of how well the waist fits.
- Inseam — Measure from the crotch seam down to the ankle bone while standing. Full-length leggings typically have a 27–30 inch inseam depending on the brand. This measurement is most important when choosing between regular, tall, or 7/8 cropped lengths — a difference of just one inch changes where the hem falls and whether it looks intentional or just short.
According to Women's Health, taking measurements in fitted clothing — not over bulky layers — and using a flexible tailor's tape rather than a rigid ruler gives the most accurate result. Write your numbers down before you shop. And when two measurements point to different sizes, always size up: leggings stretch and conform to your body, but they cannot create space where there isn't any.
With your measurements in hand, the chart below will tell you exactly where you fall.
Leggings Size Chart: Standard US Women's Sizing
The table below reflects standard US women's activewear sizing. Use your waist and hip measurements together — if they land in different size columns, go with the hip measurement. That's where leggings are most likely to feel restrictive, and where the fit matters most for movement.
| Size | Waist (inches) | Hips (inches) | Inseam (inches) |
|---|---|---|---|
| XS | 23.6–27.6 | 31.5–35.4 | 27 |
| S | 25.6–29.5 | 35.4–39.4 | 28 |
| M | 27.6–31.5 | 39.4–43.3 | 28 |
| L | 29.5–33.5 | 43.3–47.2 | 28.5 |
| XL | 38.6–42.5 | 46.1–49.2 | 28.5 |
This chart matches the size guide on every Glossy legging product page — the numbers you measure here are the exact numbers you'll shop by.
High-waist styles — These sit 2–3 inches above the natural waist. If you prefer very firm compression through the core, you can size down within the same waist range. If you want smooth, supportive hold without cinching, stay true to size. When in doubt: true to size is the right call for high-waist silhouettes.
Seamless or ribbed styles — Seamless fabric offers more four-way stretch than structured compression fabric. It's forgiving at the waist but can feel loose through the seat if you size up. True to size gives you the intended silhouette and compression level.
Performance and running styles — Cut closer through the leg for reduced drag and chafe during movement. If you're at the top end of a size range — especially in the hip measurement — size up one. A secure waistband matters more than a snug thigh when you're running or training at speed.
According to the American Council on Exercise, activewear that restricts circulation or creates friction during exercise can increase fatigue and reduce performance output. When a size feels borderline, go larger — freedom of movement is always the priority.
How to Know Your Leggings Actually Fit
A size chart gets you close. These real-world checks confirm the fit is right — or tell you to go a size in either direction before you commit to a workout in them.
The waistband test — Pull the waistband up to where it will sit during your workout, then do a slow forward fold and a bodyweight squat. A correctly fitted high-waist legging stays exactly where you placed it. If it rolls down more than half an inch during either movement, the waistband is too loose or the rise isn't suited to your torso proportions. A roll is always a fit signal, never a fabric flaw.
The hip crease test — Sit down fully in the leggings. You should feel held, not squeezed. Deep pulling across the hip or thigh fabric means the legging is working harder than it should in that zone — consider sizing up. Some light fabric gathering at the inner knee when seated is completely normal. Tension that doesn't release when you stand is not.
The standing mirror check — Look at the fabric across the seat and thighs in natural light. It should appear smooth and evenly distributed at every angle. If you can see sheerness across the seat when you stretch forward, the fabric has exceeded its design tension — that's a size issue, not a quality issue. Sizing up restores the intended coverage and compression.
At Glossy Boston, our fit philosophy is built around the idea that compression should feel like support — not restriction. The Soft Sculpt fabric holds its density under stretch, which means the finish you see in the mirror is the finish you get mid-workout.

The Glossy Edit: Built for Your Body, Not a Generic Chart
Knowing your measurements is step one. Step two is choosing a legging designed to actually honor them. At Glossy, sizing is calibrated across four fit zones — waistband, seat, thigh, and ankle — so that a Medium isn't just a "middle" option, but a precise fit for a precise set of body measurements.
The Satin High Waist Sculpt in Cirré Black is one of our most consistently accurate-fitting styles across the full size range. The Cirré fabric — a high-density compression material with a smooth satin finish — has a tighter weave than our matte styles. That means firmer, more consistent compression at every size without sacrificing the stretch you need for movement. It doesn't thin across the hips, it doesn't roll at the waist, and the inseam sits at a clean ankle length for most heights in the S–L range.
If you're between sizes in the waist-to-hip conversion, the high-waist silhouette works in your favor: the structure at the torso holds even when you're at the top of your waist range. The fabric does the work so the size doesn't have to be mathematically perfect.
Activewear that fits is activewear you actually wear — not the pair you keep meaning to return, not the one you save for "good days." The pair you reach for first, every single time. That's what a size chart is really for.

FAQ
What if I'm between sizes on a leggings size chart?
When your waist and hip measurements fall in different size columns, always follow the hip measurement. Leggings can accommodate a slightly looser waist — especially high-waist styles, which create structure at the torso — but they cannot create horizontal space across the hip and thigh. Sizing up based on your hip measurement ensures freedom of movement and prevents the pulling, constriction, or sheerness that comes from undersizing in that zone.
Should I size up or down in high-waist leggings?
For most high-waist legging styles, size true to your hip measurement. High-waist cuts are engineered to compress and hold at the torso regardless — that compression is built into the design. Sizing down to get a tighter waist fit typically creates restriction through the hip and seat, reducing range of motion and causing the fabric to thin under stretch. True to size gives you the intended silhouette and compression without sacrificing comfort.
How do legging sizes compare to regular pants sizes?
Legging sizes (XS through XL) don't map directly to numerical pants sizes, but as a general reference: XS corresponds roughly to US pants size 0–2, S to 4–6, M to 8–10, L to 12–14, and XL to 16–18. These are loose equivalents only. Activewear brands size to body measurements — waist and hip circumference in inches — not to the arbitrary numerical scale used in denim and tailored trousers, which varies widely between brands. Always use a brand's measurement-based size chart for activewear rather than converting from a pants size.
