Finding the perfect pair of leggings can be tricky, especially when shopping online. Uniqlo is known for its minimalist style and high-performance fabrics like AIRism and HEATTECH, but understanding their sizing is key to getting the most comfortable and flattering fit. Whether you’re shopping for casual wear, workouts, or layering pieces, this guide breaks down everything you need to know about Uniqlo leggings sizing.
1. Understanding Uniqlo’s Sizing System
Uniqlo typically uses a combination of standard letter sizing (XS–XXL) and numerical sizing in some regions. Their sizing is based on Japanese measurements, which may run slightly smaller than US or European brands.
- Women’s Sizes: XS to XXL (some items available in 3XL online)
- Men’s Sizes: S to XXL
- Plus Sizes: Select styles are available in extended sizes, mostly online
- Tall & Petite Options: Limited, but some leggings offer adjustable hems or stretch to accommodate different heights
2. Check the Uniqlo Size Chart
Always refer to the official Uniqlo size chart before purchasing. Measurements are listed in inches and centimeters for waist, hips, and inseam.
Sample Women’s Size Chart:
| Size | Waist (inches) | Hip (inches) | Inseam (inches) |
|---|---|---|---|
| XS | 22–24 | 31.5–33.5 | 27.5–28.5 |
| S | 24.5–26.5 | 34–36 | 28–29 |
| M | 27–29 | 36.5–38.5 | 28.5–29.5 |
| L | 29.5–31.5 | 39–41 | 29–30 |
| XL | 32–34 | 41.5–43.5 | 29–30 |
| XXL | 34.5–36.5 | 44–46 | 29.5–30.5 |
Note: Measurements may slightly vary depending on fabric stretch and product line.
3. Know the Different Fabric Fits
Uniqlo offers several fabric technologies, each with its own stretch and compression level, which can affect how the leggings fit.
- AIRism: Lightweight, cooling, and ultra-stretchy – fits close to the body, ideal for warmer climates or workouts.
- HEATTECH: Thermal leggings with a snug fit – excellent for layering in cold weather.
- Ultra Stretch: Offers the most flexibility – great for all-day comfort and active movement.
Tip: If you’re between sizes and prefer a snug fit, size down in Ultra Stretch. For HEATTECH, stick to your regular size to ensure warmth and layering comfort.
4. Length Options and Fit Tips
While most Uniqlo leggings are designed to hit at the ankle, lengths can vary by design and your height.
- Ankle Length: Standard for most styles
- 7/8 Length: Slightly cropped; great for petites
- Full Length: Available in selected styles for taller shoppers
Fit Tip: Try leggings in-store if possible or order two sizes to compare, especially if you’re unsure about length or fit preference.
5. How to Measure Yourself Correctly
To find your perfect size, use a flexible tape measure and stand in front of a mirror.
- Waist: Measure around your natural waistline, just above the belly button
- Hips: Measure around the fullest part of your hips and buttocks
- Inseam: Measure from the top of your inner thigh down to the ankle
6. Try Before You Commit
Uniqlo’s return policy allows for returns and exchanges within a specific time window, so don’t be afraid to try a couple of sizes.
- Online Orders: Read reviews for fit feedback
- In-Store Shopping: Use fitting rooms and size guides displayed in-store
