Are leggings sizes the same as regular pants sizes?

Often, but not always. Athletic leggings (Lululemon, Alo, Athleta) typically run 1 size smaller than regular pants — a regular size 8 wears Lululemon size 6. Lifestyle leggings (Aerie, Old Navy) run true to regular sizing. Always check the brand's specific chart.

What inseam length should I get for leggings?

Match to your typical jean inseam. 25" inseam (cropped, ankle): 5'4" and under. 28" inseam (regular): 5'4"–5'7". 31" inseam (long, full-length): 5'7"–5'10". 33"+ inseam (extra long): 5'10"+.

Should leggings be high-rise or mid-rise?

High-rise (10"+ rise) sits at the natural waist, holds in the stomach, and prevents waistband roll. Mid-rise (8–9" rise) sits below the navel — comfortable for some, but more prone to sliding down during activity. Most workout leggings are high-rise; lifestyle leggings vary.

Do leggings stretch out over time?

Yes. After 3–6 months of regular wear, most leggings lose 5–10% of their compression. The waist gets slightly looser; the seat may sag. High-quality leggings (Lululemon Align, Alo Airbrush) hold shape longer. Replace when the waistband no longer holds without rolling.

Leggings Size Chart (XS to 4XL) — Waist, Hip, Inseam

Q: What size leggings should I buy?

Match waist, hip, and inseam to the brand's chart. Most leggings size by waist + hip; inseam is built into the design (often listed as 25", 28", 31" — short, regular, long). XS typically fits 0–2; S fits 4–6; M fits 8–10; L fits 12–14; XL fits 16–18.

Q: How tight should leggings be?

Snug everywhere, never compressing. The waistband should not roll down; the seat should be smooth (no sagging); the leg should not bunch at the ankle. If you can pinch more than 1" of fabric, size down. If you can't take a deep breath comfortably, size up.

Three measurements — waist, hip, inseam — match leggings sizing across athletic, lifestyle, and shapewear. Here's the full chart from XS to 4XL with brand-specific notes for Lululemon, Alo, Athleta, Aritzia, and more.

Master Leggings Size Chart

Letter	US numerical	Waist	Hip	EU
XXS	00	23–24"	33–34"	30
XS	0–2	24–26"	34–36"	32
S	4–6	26–28"	36–38"	34–36
M	8–10	28–30"	38–40"	38–40
L	12–14	30–33"	40–43"	42–44
XL	16–18	33–36"	43–46"	46–48
2XL	20–22	36–40"	46–50"	50–52
3XL	24–26	40–44"	50–54"	54–56
4XL	28–30	44–48"	54–58"	58–60

Stretch fabric (4–6% spandex typical) means leggings can fit a 1\" range without issue. Always pick the size whose waist and hip both match your body — don't size up just because hip is at the top of the range.

Inseam Reference for Leggings

Inseam	Style	Best for
21"	Crop / ankle crop	5'2" and under, or any height as cropped style
23–25"	Cropped 7/8	5'2"–5'5"
25–27"	7/8 length / ankle	5'4"–5'7"
28–30"	Regular full length	5'5"–5'9"
31–33"	Long / tall	5'9"–6'0"
34"+	Extra-long	6'0"+

Some athletic leggings come in inseam options (Lululemon Align is 21\", 23\", 25\", 28\", 31\"; Alo Airbrush is 23\", 25\", 28\"). Lifestyle leggings often only stock one inseam — check before ordering.

Brand-Specific Calibration

Lululemon

Runs about 1 size smaller than US regular. A Lululemon size 6 ≈ regular size 8. Sizing 0–14 (XS to L); plus sizes 16, 18, 20 in select styles. Align is the buttery-soft staple; Wunder Train is firmer compression.

Alo Yoga

Runs slightly small. A regular size 8 wears Alo M. Airbrush (their staple) is high-rise, full coverage. Sizing XS to L commonly; 2XL in select styles.

Athleta

Runs true to regular sizing. Includes "petite" and "tall" inseam options for many styles. Wide size range (XXS to 3X). Salutation Stash is the workhorse.

Aritzia (Tna, Wilfred)

Runs true to size with slim cuts. Equator is the high-compression athletic line; Atmosphere is buttery soft. Sizing XXS–XL.

Beyond Yoga

Runs true to size or slightly large. Buttery soft, excellent for plus sizes. Spacedye is the best-known fabric. Sizing XS to 4X.

Spanx

Compression-heavy. Faux Leather, Booty Boost, and Look At Me Now lines size by waist + hip. Run true to size with high compression — don't size down expecting tighter fit.

Aerie / OFFLINE

Runs true to regular sizing. Lifestyle (Aerie) tends to be lower compression; OFFLINE (their athletic line) is firmer. Sizing XXS to XXL.

Old Navy / Gap PowerSoft

Runs slightly large compared to athletic-specialty brands. Old Navy size 8 ≈ Lululemon 8 or 10. Wide size range (XS to 4X).

Style Decoder

High-rise leggings

10\"+ rise. Sits at natural waist. Holds in stomach; prevents roll-down. Best for high-impact activity, postpartum, and anyone who finds mid-rise slides.

Mid-rise leggings

8–9\" rise. Sits below navel. More casual feel; some find it more comfortable for low-impact wear or layering under longer tops.

Compression leggings

Tight, firm fabric (often 20%+ spandex). Used for running, intense workouts, recovery. Spanx Look At Me Now, 2XU, CW-X.

Buttery-soft / lifestyle leggings

Lighter compression, smoother feel. Lululemon Align, Alo Airbrush, Beyond Yoga Spacedye. Best for yoga, casual wear, low-impact.

Pocket leggings

Side or back pockets for phones, keys, cards. Athleta Salutation Stash, Lululemon Speed Up.

Crossover-waistband leggings

V-shaped or crossed waistband. Lounge style. Aerie Crossover, Free People Movement Surf's Up.

What to Check on the Size Chart

Waist measurement — should match your natural waist within 1\".

Hip measurement — should match your fullest hip within 1\".

Inseam — match your preferred length.

Rise — high (10"+), mid (8–9"), low (under 8").

Fabric content — 4–6% spandex is standard. Less = looser fit. More = tighter compression.

Cuff opening — for tapered cuffs, ankle circumference matters. See our ankle measurement guide.

Common Mistakes

Buying down a size for tighter fit

Stretch leggings size up will fit close-but-comfortable. Sizing down compresses too much, restricts movement, and accelerates seam wear.

Ignoring brand calibration

A "size 8" varies by 1–2 sizes across leggings brands. Always check the specific brand's chart in inches.

Not checking inseam for tall or petite

Standard 28\" inseam doesn't fit a 5'10" person well. Many brands offer inseam variations — use them.

Wearing too-old leggings

After 3–6 months of regular wear, leggings lose compression and the waist rolls. Replace at the first signs of waistband sag.

Three Numbers, Right Leggings

Waist, hip, inseam. Add brand calibration and rise as decisions, and leggings sizing solves itself. The hardest part is keeping up with how often the elastic gives out.
