Triumph Motorcycles Size Guide
Triumph Motorcycles apparel is designed for riders who demand authentic, heritage-inspired gear built for performance and style. The brand's sizing reflects European cut standards, which typically run slimmer and longer through the torso and sleeves than North American equivalents. Triumph offers distinct fit styles—Straight Fit, Leather Fit, Textile Fit, and Comfort Fit—each engineered for different riding positions and layering needs. Whether you're selecting a textile jacket for daily commuting, a leather race jacket for spirited rides, or protective riding jeans, accurate chest, shoulder, and inseam measurements are essential to achieving the ideal fit.
How to Measure
- Chest: Wearing a fitted t-shirt, measure horizontally around the fullest part of your chest, keeping the tape parallel to the ground. Do not pull tight; allow one finger's width of ease.
- Shoulder width: Measure from the top of one shoulder bone to the top of the other, across the back. This ensures sleeves will land at your wrist.
- Sleeve length: With your arm relaxed at your side, measure from the centre back of your neck, across your shoulder, and down to your wrist bone. Divide by two for the back shoulder-to-cuff measurement.
- Waist: Measure around your natural waistline (where your trousers normally sit) with the tape snug but not constricting.
- Inseam: Wearing motorcycle boots or the footwear you'll ride in, measure from your inner thigh to the top of your ankle or boot shaft. This is critical for riding jeans and trousers.
- Hips (women's): Measure horizontally around the fullest part of your hip and thigh, approximately 20 cm below your natural waist.

Product-Specific Guidance
Riding Jackets (Textile, Leather & Hybrid)
Triumph riding jackets are engineered with protective armour pockets and ergonomic seaming for a forward riding posture. Measure your chest, shoulder width, and sleeve length carefully. Leather jackets typically have a Leather Fit (slimmer) or Comfort Fit (roomier) option; textile jackets may run slightly looser to accommodate thermal liners. Allow approximately 2–3 cm of ease over a base layer; jackets should never be tight across the shoulders or restrict arm movement at full throttle. If between sizes, choose the larger size and rely on adjustable waist tabs for a refined fit.
Riding Trousers & Jeans
Triumph riding trousers and reinforced riding jeans are cut for the mounted position—knees slightly bent. Inseam is critical and varies by trouser type: standard riding trousers feature an 81 cm inseam for most waist sizes; denim variants are available in Short (76 cm), Regular (81 cm), and Long (91 cm) options. Measure your true inseam in your riding boots. Waist should sit comfortably at your natural waistline without riding up or twisting when you're seated on the bike. European sizing may feel tighter in the thigh and seat than North American brands; if you favour layering or a relaxed fit, consider sizing up one waist size.
Base Layers & Riding Essentials
Triumph base layers, thermal liners, and high-visibility layers typically come in combined sizes (XS–S, M–L, XL–2XL) designed to layer under jackets and over core riding gear. Choose your size based on chest measurement to ensure proper thermal contact and moisture-wicking performance. These items are engineered for year-round comfort; size snugly over your torso, as loose base layers can bunch under armour or create hot spots on long rides.
Boots
Motorcycle boots run true to UK and EU size standards. Always try boots on with the socks you intend to wear when riding. Feet swell during long rides, so a small amount of extra room (approximately one finger's width) is acceptable. The ankle should be supported without pressure points, and the heel should not slip when you pull up on the boot shaft. Triumph boots are designed for ground-to-peg feel and protection; prioritise security and comfort over a snug fit.
Gloves
Triumph motorcycle gloves are sized by UK hand circumference or international designations (XS–3XL). Measure around the widest part of your hand (excluding the thumb) with a soft tape, keeping it snug but not constricting. Gloves should fit closely enough to provide tactile feedback on throttle and brake controls, yet allow room for thermal liners in winter styles. If you have narrow wrists or wear glove liners frequently, you may prefer to size down by half a size.
Sizing Tips
- European Cut Heritage: Triumph apparel reflects British–European tailoring, which is typically slimmer through the chest and shoulders than North American mainstream brands. If you usually wear a Large in US brands, start with Triumph's Large but be prepared to size up if you have a rounder chest or prefer layering room.
- Always Measure in Riding Position: When measuring sleeve length and inseam, sit upright as you would on the motorcycle. This ensures sleeves reach your wrist without pulling, and trousers don't ride up or bunch at the knee when you're in the saddle.
- Account for Layering: If you plan to wear thermal base layers or a waistcoat under your jacket, add 1–2 cm to your true chest measurement when selecting a size. Jackets should never be so tight that layering restricts arm movement or breathing.
- Inseam Variation: Triumph riding trousers come in fixed inseam lengths; standard riding trousers are 81 cm on all waist sizes. Jeans and casual trousers offer Short, Regular, and Long options. Measure accurately to your riding boot heel to avoid excess fabric bunching at the ankle.
- Leather vs. Textile Break-In: Leather jackets require a brief break-in period and may feel snug initially; size to your true measurements and expect 1–1.5 cm of natural stretch over the first few wearing hours. Textile jackets run truer to size from day one and do not stretch significantly.
- Try Before You Buy When Possible: European sizing conventions and style-specific cuts mean that online returns and exchanges are common. If purchasing remotely, verify the merchant's return policy and consider ordering two sizes if you are between sizes.
- Women's Fit Runs Smaller: Women's Triumph sizes use UK dress sizing; a UK 12 is equivalent to a US 8. Women's jackets and trousers are cut with contoured seams and darts for a feminine silhouette while maintaining full protection and mobility for riding.
- Belt Sizing: Triumph lifestyle belts come in S–M and L–XL; match your trouser waist size. S–M suits 30–34" waists, and L–XL suits 34–38" waists. Belts should be worn at your natural waistline, not slung low.
