2XU Size Guide
2XU (Two Times You) is a global leader in high-performance compression wear and activewear, trusted by elite athletes, triathletes, and fitness enthusiasts worldwide. Engineered with advanced compression technology, 2XU garments are designed to support blood flow, enhance muscle recovery, and optimise athletic performance. Unlike standard sportswear, 2XU's compression fit is intentionally snug across specific zones—this tightness is by design and essential for the product's performance benefits. Whether you're purchasing compression tights for recovery, technical race wear for triathlon, or training shorts for the gym, understanding 2XU's sizing philosophy is crucial for finding your perfect fit. This guide covers all major product categories including women's and men's compression tights, shorts, socks, and lifestyle pieces, with detailed measurement instructions and comprehensive size charts to help you select the right size first time.
How to Measure Yourself for 2XU
Accurate body measurements are essential for finding the correct 2XU size, particularly for compression garments where fit directly impacts performance. Follow these steps carefully, ideally wearing minimal clothing:
- Waist Measurement: Locate the narrowest point of your waist, typically just above your belly button. Wrap a measuring tape around this area horizontally, keeping it snug but not tight. Record the measurement in both centimetres and inches. This is the primary measurement for determining 2XU compression tights sizing.
- Hip Measurement: Measure around the widest part of your lower body, across your hip bones and buttocks. Keep the tape measure level and parallel to the ground. This measurement is critical for tights and shorts, as it must fall within the specified range for your chosen size.
- Chest Measurement: For tops, sports bras, tri suits, and sleeves, measure around the fullest part of your chest, typically at nipple level. Keep the tape measure horizontal and snug without compression. Record this measurement for sizing tops and race wear.
- Height: Stand barefoot against a wall and measure your height from the floor to the top of your head. 2XU uses height in combination with weight for elite compression ranges and to determine inseam length for tights (regular vs. tall versions).
- Weight: Weigh yourself on a reliable scale, preferably in the morning. Some 2XU compression ranges are weight-based, particularly for elite performance products. Record your weight in both kilograms and pounds.
- Calf Circumference (for socks and sleeves): Measure around the fullest part of your calf muscle. Sit with your leg extended or stand with your foot elevated on a step. This measurement is essential for determining correct compression sock and sleeve sizing, as these products are sized by calf circumference rather than shoe size alone.
- Cross-Check Your Measurements: Measure yourself twice to ensure accuracy, ideally on different days. If measurements vary slightly, use the average. Record all measurements in both metric (cm, kg) and imperial (inches, lbs) systems for flexibility when consulting size charts.

2XU Product Categories & Fit Guidance
Core Compression Tights
2XU's signature Core Compression Tights utilise graduated compression technology to support blood flow and enhance muscle recovery. These tights are designed to feel noticeably snug when first worn—this tight fit is intentional and provides the performance benefits. The compression is strongest at the ankles and gradually decreases towards the waist. Always base sizing on waist and hip measurements, not dress size. Many UK shoppers mistakenly size up, which compromises the compression technology. If you're between sizes, choose the smaller size for true compression performance. Women's versions feature a high rise and shorter inseam compared to men's, so always select the appropriate gender-specific product.
Aero Shorts & Tank Tops
2XU's lifestyle and training range, including Aero shorts and tank tops, runs true to size and uses standard sportswear fit (not compression). These pieces feature breathable mesh panels and lightweight fabrics designed for comfort during training. Unlike compression garments, you can expect a more relaxed fit in this category. If you're between sizes and prefer a fitted gym aesthetic, sizing down is acceptable for these products. Check individual product descriptions, as some items may vary slightly in fit.
Recovery Compression Socks & Sleeves
Recovery compression socks and sleeves are sized exclusively by calf circumference, not shoe size. Your shoe size is merely a reference point. Measure your calf at its widest point whilst standing or with your foot elevated. These products are available in multiple width options within each size category to ensure optimal fit across different calf shapes. Compression sleeves are particularly important for precise sizing, as an incorrectly sized sleeve will either slip down or restrict circulation.
Triathlon & Race Wear
2XU triathlon suits, wetsuits, and race-specific apparel combine compression technology with highly specialised fabric and design. These products are gender-specific with tailored cuts for men and women. Fit is critical for both performance and comfort during endurance events. For tri suits, base sizing on chest measurement for the top portion and waist/hip for the shorts section. Wetsuits require particularly precise sizing; consult the specific product fit guide as sizing can vary by thickness and material.
Gender-Specific Fit Differences
2XU offers both unisex and gender-specific products across its range. Here are the key differences:
| Feature | Women's Fit | Men's Fit |
|---|---|---|
| Rise (Tights) | Higher rise designed for female anatomy | Standard to lower rise for male anatomy |
| Inseam Length | Shorter inseam; available in regular and tall versions | Longer inseam; tall versions for taller athletes |
| Torso Width | Tapered through shoulders and bust area | Broader across shoulders and chest |
| Unisex Products | For compression gear, base on waist/hip measurements | For compression gear, base on chest/waist measurements |
| Sports Bras | Multiple cup/band size combinations available | N/A |
Size Comparison: 2XU vs Other Brands
Understanding how 2XU sizing compares to competitors can help if you're familiar with other activewear brands:
| Brand | Fit Style | Compression Level | Sizing Notes |
|---|---|---|---|
| 2XU | Engineered tight | High (graduated) | True to measurement; don't size up |
| SKINS | Compression-focused | High | Comparable sizing to 2XU; similar graduated compression |
| Nike | Standard activewear | Low to medium | Typically runs larger than 2XU; generally runs true to size |
| Lululemon | Slim fit | Medium | Similar waist fit to 2XU but with more give; generally true to size |
| Under Armour | Sporty contour | Medium | Runs true to size; less compression than 2XU |
Sizing Tips for 2XU
- Never Size Up for Comfort: The tight fit of 2XU compression wear is engineered for performance and recovery. If a size feels snug when you first try it on, this is correct. Sizing up will completely negate the compression benefits. Allow 1–2 wears for the fabric to settle and your body to acclimate to the compression sensation.
- Prioritise Waist & Hip Measurements Over Dress Size: UK dress sizes (6, 8, 10, 12, etc.) vary significantly between manufacturers. Always measure your actual waist and hip circumference and cross-reference these against the 2XU size chart rather than guessing based on your typical clothing size. A UK 10 might be XS, S, or M depending on your specific measurements.
- Account for Height When Choosing Tall Versions: 2XU offers regular and tall versions of many tights and leggings (indicated by suffixes like "T" or "Tall"). If you're taller than 175cm (5'9"), tall versions will provide the correct inseam length and prevent excessive fabric bunching at the ankles, which compromises compression effectiveness. Conversely, if you're shorter than 155cm (5'1"), regular versions prevent excess fabric that can roll or shift.
- Calf Measurement is Critical for Socks & Sleeves: Compression socks and sleeves sized by shoe size alone will not fit correctly. Always measure your calf circumference and note whether your calf is slim, average, or muscular. 2XU offers multiple width options (e.g., Medium-1 and Medium-2) within the same size; choosing the correct width ensures the compression sleeve or sock stays in place and provides optimal compression without cutting off circulation.
- Review Product-Specific Fit Guidance: Different 2XU product lines may have slightly different sizing philosophies. Always check the specific product description or fit guide before ordering. Compression tights follow one sizing system; Aero shorts and tank tops run true to size with a more relaxed fit; triathlon suits and wetsuits have their own specialist sizing. A size M in compression tights may not be identical to a size M in an Aero tank top.
- Consider Compression Levels When Sizing: 2XU offers various compression levels within its range (e.g., light compression, mid-range compression, elite compression). Higher compression levels may feel tighter, but the sizing guidance remains the same—base it on your measurements, not comfort preference. If you're new to compression wear, starting with a mid-range compression product in the correct size is recommended before progressing to elite compression.
- Allow Time for Fabric Settlement: New 2XU compression garments may feel exceptionally snug for the first few wears. The fabric and your body both need time to adjust. Wear compression tights for short periods initially (30 minutes–1 hour) before progressing to longer sessions. The fit will feel more natural after 2–3 wears, though the compression sensation may remain pronounced depending on the product.
- Cross-Check Weight & Height If Using Elite Ranges: Some 2XU elite compression products are sized by weight and height rather than standard measurements. If your weight and height fall near the boundary between two sizes, use your waist and hip measurements to confirm the correct choice. If measurements suggest size M but weight/height suggests size L, the waist/hip measurements take precedence.
- Gender-Specific Tights Provide Better Fit: Whilst unisex compression is available, women's and men's specific tights will always provide a superior fit due to tailored cuts, rise height, and inseam proportions. Choose gender-specific products whenever possible rather than opting for unisex alternatives.
- Verify Return Policies Before Ordering: Given the critical importance of compression fit, always review the brand's return and exchange policy before purchasing. Many stockists offer extended return windows for 2XU products, allowing you to try items at home. If the compression fit doesn't feel right after 2–3 wears, exchange for a different size rather than keeping an incorrectly sized garment.
