Whether you're shopping for t-shirts, hoodies, joggers, or other performance wear, Gym King delivers consistent sizing across its range.
How to Measure
To ensure you select the correct Gym King size, follow these simple measurement steps. You'll need a soft measuring tape and should wear fitted clothing or minimal layers.
- Chest Measurement: Stand upright and measure around the fullest part of your chest, keeping the tape parallel to the ground. The tape should be snug but not tight. This measurement determines your size in most tops, t-shirts, and jackets.
- Waist Measurement: Measure around your natural waist (the narrowest part of your torso) at your navel level. Keep the tape loose enough that you can fit a finger underneath. This is essential for selecting the correct trousers, joggers, and shorts sizes.
- Hip Measurement: Measure around the fullest part of your hips and glutes whilst standing with feet together. This measurement is particularly important for leggings, fitted trousers, and skirts.
- Length Measurements: For tops, measure from the shoulder seam down to your desired hem length. For bottoms, measure from your waist to your ankle. These measurements help ensure proper proportions and prevent items that are too long or too short.
- Measure Both Sides: Your left and right sides may differ slightly. If there's a discrepancy, use the larger measurement to ensure a comfortable fit.
- Measure in the Afternoon: Feet and body measurements can swell throughout the day due to activity and food intake. Take measurements in the late afternoon or evening for the most accurate sizing, particularly if you plan to wear the clothing during or after training sessions.
- Record and Compare: Write down all your measurements and compare them to the size charts below. When your measurements fall between two sizes, consult the specific product description and customer reviews to determine whether you should size up or down.

Product-Specific Sizing Guidance
T-Shirts & Tops
Gym King t-shirts and tops are cut with a contemporary fit that emphasises the shoulders and chest whilst tapering at the sides. If you prefer a looser, more relaxed fit, consider sizing up. The brand's signature designs work best when fitted close to the body, so if you fall between sizes, choose the smaller option for optimal proportion.
Joggers & Tracksuit Bottoms
Joggers feature a tapered ankle and mid-rise waistband. Gym King joggers are designed to sit comfortably at the natural waist without binding, with the inseam proportioned for standard heights. If you're particularly tall or short, check the product length specifications, as this is where individual jogger styles may vary most significantly.
Hoodies & Outerwear
Hoodies and jackets offer slightly roomier cuts to allow for layering. The drawstring hoodies are designed to cinch at the waist for a flattering silhouette. If you plan to wear these items over fitted clothing, your normal size is recommended. For an oversized aesthetic, size up.
Leggings & Fitted Bottoms
Women's leggings from Gym King are high-waisted with substantial support. Sizing runs true, though customers with petite or curvy builds often note that the M–L size range accommodates a range of body types. Always check product reviews for fit feedback on individual legging styles, as some feature additional compression whilst others offer a softer, more relaxed feel.
Trainers & Footwear
Gym King trainers typically follow standard UK shoe sizing with moderate widths suitable for average to athletic feet. If you have particularly wide or narrow feet, check customer reviews for width feedback. When ordering online, allow for a fitting period—trainers may require a brief break-in time, particularly in the heel area.
Sizing Tips
- Always consult the specific product size chart: Gym King offers various fits across its range. T-shirts may fit differently from hoodies, and oversized designs have their own proportions. Before purchasing, check the individual product page for detailed measurements including length, sleeve length, and any specific fit notes provided by the brand.
- Read customer reviews for fit feedback: Real customer experiences provide invaluable insights into whether items run large, small, true to size, or require consideration of your specific body type. Look for reviews from customers with similar builds to you for the most accurate guidance.
- Account for your training intensity: If you'll be wearing Gym King apparel for intensive workouts, consider that you may want slightly less fitted styles to allow for freedom of movement and breathability. Performance-specific items may fit differently than casual wear.
- Check product composition and fabric: Gym King uses various fabrics from cotton-rich blends to technical performance materials. Different fabrics have different stretch and recovery properties. Polyester blends may have more give than 100% cotton, potentially affecting how the fit feels across sizes.
- Consider the seasonality of your purchase: Items designed for layering (hoodies, jackets) should accommodate your typical layers. Conversely, lightweight performance wear may fit more closely to your body. Ensure you account for what you'll wear beneath each piece.
- Measure your current well-fitting garments: Compare measurements from items in your wardrobe that fit you perfectly with the Gym King size chart. This eliminates guesswork and provides a direct comparison point—lay a well-fitting t-shirt flat and measure its chest width across the front, then double it for total chest measurement.
- Factor in shrinkage for cotton-rich garments: Most Gym King items should be machine washed in cool water and tumble dried on low or air dried to minimise shrinkage. If an item is primarily cotton, it may shrink slightly in the wash, so this is worth considering when sizing.
- Use the brand's international shipping and returns: Gym King ships to numerous countries and typically offers free returns within a specified period. If you're uncertain between sizes, order both and return the incorrect size—this often proves more efficient than guesswork, particularly for fitted items.
- Contact customer service for personalised advice: Gym King's customer service team are familiar with the brand's sizing quirks and can provide guidance based on your specific measurements and preferred fit. They can also advise on the appropriateness of sizing up or down for particular styles.
- Monitor sizing consistency across seasons: Like most fashion brands, Gym King may occasionally revise fits or work with different manufacturers for certain items. If you've purchased from the brand before, don't assume new season items fit identically to previous purchases—always check updated size charts and reviews.
