This guide will help you find your perfect Nerf size across our range of youth and adult categories.
How to Measure
- Chest: Wrap a soft measuring tape around the fullest part of your chest, keeping it parallel to the ground. Do not pull tight; allow one finger's width of ease.
- Waist: Measure around your natural waist at the narrowest point, just above your hip bones. Keep the tape relaxed but not loose.
- Hips: Measure around the fullest part of your hips and bottom, keeping the tape parallel to the ground.
- Foot Length: Stand on a flat surface with your heel against a wall. Place a ruler or measuring tape on the floor and measure to the tip of your longest toe. Measure both feet in the evening, as feet swell throughout the day.
- Shoe Width: For the most accurate fit, have your foot width measured by a professional fitter. If unavailable, compare your foot width to brand-specific width guides (typically offered in standard, narrow, or wide options).
- Sleeve Length: For jackets and long-sleeved apparel, measure from the centre back of your neck, across the shoulder, and down to your wrist bone with your arm relaxed at your side.

Product-Specific Guidance
Action Vests & Tactical Gear
Nerf action vests and tactical harnesses are designed to fit snugly over regular clothing without restricting arm movement. Measure your chest and refer to our chart above. If you fall between sizes, choose the larger option to ensure comfort during intense play sessions. Youth vests are tailored for children aged 6–14 and feature adjustable straps to accommodate growth over a season. Adult vests offer a more structured fit; if you have a larger chest measurement, prioritise comfort and opt for the size above your baseline measurement rather than sizing down for a snug appearance.
Performance Trainers
Nerf trainers emphasise grip, stability, and lateral support for dynamic outdoor play. Our trainers run true to size, though we recommend measuring your foot in the evening when it is slightly swollen. Youth trainers (sizes UK 1–5) feature reinforced toeboxes and flexible soles designed for playground impact. If you are between sizes, size up to allow room for growth or thicker play socks. Adult trainers (UK 6 and above) offer responsive cushioning in the heel and forefoot. Women's trainers typically run narrower than men's in the same UK size; consult the width guidance below if you have particularly wide feet.
Hoodies & Jackets
Nerf hoodies and jackets are cut with a relaxed fit to accommodate layering and allow full freedom of movement. Measure your chest and select your size based on the chart provided. Our hoodies feature extended sleeves to cover the wrists during active play; if you have particularly long arms, check the sleeve length column and consider sizing up. Youth hoodies often come with drawstring hoods and kangaroo pockets for storing small gear. Adult jackets typically feature zip closures and reinforced seams at high-stress points (shoulders, underarms).
Shorts & Bottoms
Nerf shorts and tactical bottoms are engineered for mobility and comfort during running and climbing. Measure your waist and hips; use the larger measurement if you fall between sizes. Youth shorts feature elastic waistbands and drawstrings for a secure, adjustable fit. Adult shorts offer a mid-rise cut with gusseted inseams for enhanced range of motion. If you have a larger hip measurement relative to your waist, consider sizing up in length to ensure the leg opening is not too tight.
Caps & Headwear
Nerf caps are sized as one-size-fits-most with adjustable velcro or snapback closures. Measure around the crown of your head (slightly above the ears) if you prefer a more snug fit. Youth caps feature smaller crown depths and shorter bill projections. If you have a head circumference above 23 inches or prefer a looser fit, check for our extended-size options or choose a cap with a full-adjustment back closure.
Sizing Tips
- Always measure in the evening. Feet and body measurements swell naturally throughout the day, especially after physical activity. Measuring in the evening gives you a true-to-life size for active wear.
- When in doubt between two sizes, size up. Action gear performs best with a little room to breathe. Oversized apparel is more forgiving during high-impact play than tight-fitting gear, which can restrict movement and cause discomfort.
- Check the product description for material stretch. Nerf gear is often made from technical fabrics with 4-way stretch. If a product offers elastane or spandex content above 5%, you may comfortably wear your true-to-size measurement. Non-stretch woven materials may warrant sizing up.
- Account for growth in youth sizes. Children typically grow 2–3 inches per year between ages 6 and 12. Select youth sizes based on current measurements, but consider a size up if the item will be worn throughout a full school year or sports season.
- Width matters for trainers. Nerf trainers are available in standard widths. If you have wide feet, try the shoe on in-store if possible, or look for models with a wider toe box (check product reviews). Consider sizing up half a size in length, which typically increases width as well.
- Wash care affects fit. Check care labels before purchase. Most Nerf apparel is machine-washable in cold water, but some performance fabrics may shrink slightly if dried on high heat. Air-dry your gear when possible to maintain the original fit.
- Layering affects your base size. If you plan to wear Nerf gear over heavy thermal layers or body armour, measure while wearing those layers and size up accordingly. This is especially important for youth tactical vests and adult action jackets.
