Oakley Size Guide
Oakley is a performance-focused brand known for designing technically advanced apparel, footwear, and accessories across sport, cycling, and lifestyle categories. Oakley sizing emphasises a tailored, athletic fit with attention to freedom of movement and comfort during intense activity. The brand offers consistent sizing across menswear, womenswear, and footwear, with detailed measurement guidance to ensure the best possible fit.
How to Measure
- Body Height: Measure from the top of your head to the ground. It is best to measure standing against a wall for accuracy.
- Arm Length: Measure from the shoulder joint to the wrist, keeping the elbow slightly bent.
- Chest: Measure around the widest part of the chest, generally above or at the nipple line, without pinching.
- Waist: Measure just above the navel without pinching or pulling the tape tight.
- Hips: Measure the widest part around the bottom and hip area.
- Inside Leg Length: Measure the distance from the top of the inside leg to below the ankle. This is essential for trousers and footwear fit.
- Outside Leg Length: Measure from the hip joint to the ankle along the outside of the leg.
- Neck: Measure the thickest part of the neck, just below the Adam's apple for men.
- Thigh: Measure the widest part around the thigh.
- Calf: Measure the circumference of the largest part of the calf.
- Ankle: Measure the circumference of the smallest part of the leg just above the ankle.
Tip: Have someone else help you with measurements for the most accurate results.

Product-Specific Guidance
Outerwear & Jackets
Oakley jackets and outerwear are designed with an athletic, performance-focused silhouette. Ensure your chest measurement falls comfortably within the specified range; too-tight jackets restrict movement and reduce breathability. Check arm length carefully, as Oakley styles are tailored for active use and should not be oversized. If your measurements fall between two sizes, we recommend ordering the larger size for greater comfort during movement.
Trousers & Bottoms
Oakley trousers are cut with a modern athletic fit suitable for sport, training, and lifestyle wear. Pay close attention to both waist and inside leg length. For men, inside leg lengths are consistent across sizes (regular fit). For women, inside leg length is standardised at approximately 81–82 cm across sizes. If you are exceptionally tall or short, consider contacting customer service for tailoring options or alternative styles.
Footwear & Golf Shoes
Oakley golf and sport footwear follows standard UK shoe sizing. Ensure you measure your foot length in centimetres for the most accurate fit. Oakley shoes are engineered for performance, with reinforced support in high-impact areas. If your foot width is wider than average, consider sizing up a half size. Always try shoes with the socks or insoles you intend to wear, and allow a thumb's width of space between your longest toe and the shoe's toebox.
Socks
Oakley socks are sized using EU, US, and UK conversions, with Mondopoint measurements for precise foot length matching. Unisex sizing is available. For cycling and outdoor sports, socks should fit snugly without bunching or slipping; a half-size smaller is better than a full size larger.
Sizing Tips
- Always measure on bare skin: Wear minimal clothing when taking body measurements to ensure accuracy. Tight or layered clothing can skew results.
- Between sizes? If your measurements fall between two sizes, order the larger of the two. Oakley's athletic cut benefits from a comfortable fit that allows movement.
- Arm length matters for jackets: Oakley outerwear is designed with precise arm proportions. Sleeves that are too short will ride up during activity; too long will bunch at the wrist. Check arm length against the size chart before ordering.
- Inside leg length for trousers: This measurement is critical for comfort and appearance. Calf length and hiking trousers should have a slight break at the ankle; avoid hems that drag or expose too much leg.
- Shoe fit for sport: Performance footwear should feel snug at the heel and midfoot but allow a thumb's width of space at the toebox. Return shoes that slip or pinch within Oakley's 90-day return window.
- Socks affect shoe fit: Try on shoes with the same thickness of sock you plan to wear during activity. Oakley cycling and outdoor socks are thicker than casual dress socks and can change your shoe size perception.
- Check size charts by region: Oakley may offer slightly different sizing for EU, US, and UK markets. If shopping internationally, verify the size chart for your region before checkout.
- Layer for climate: When choosing outerwear size, consider the clothing you plan to wear underneath. Performance base layers add minimal bulk, but layering for cold weather may require sizing up.
