Getting the right Sting headgear size is crucial. This guide provides exact measurement steps, how to use the exact model's current size chart, model-specific fit notes, and adjustment techniques so your headgear protects as designed.
Why Correct Sizing Matters
Ill-fitting headgear fails at its job. A guard that rides too high exposes your temples, while one that drops too low blocks your vision and delays reactions. An oversized guard shifts on impact, and an undersized one restricts jaw movement and creates distracting pressure points.
For amateur competition, check whether your event and category require a headguard and which exact models are approved. A poor fit can still cause a problem at the pre-bout equipment check.
Whether you train casually or compete nationally, the right size is the foundation of your boxing headgear choice.
Measuring Your Head
Accurate measurement is essential. Skip it, and you gamble with your protection.
How to Measure
Use a flexible fabric tape measure (or string and a ruler). Position it around your head in the position shown by the exact model's measuring guide, above the eyebrows. Keep the tape level.
Measure with your hair as you typically wear it for training. Take the measurement twice, keeping the tape snug without tightening it into your skin. Record in centimetres.

Between Two Sizes?
If your measurement is on the boundary between sizes:
- Check the exact model's boundary advice first. Do not assume that choosing the larger size will always leave enough adjustment.
- Compare the two sizes where possible; head shape as well as circumference affects the fit.
- Choose a secure fit without painful pressure for every session. A heavier round is not a reason to accept a tighter or looser headguard.
Fit Checklist
Run through this checklist before your first session:
- Forehead: Padding sits ~one finger-width above eyebrows.
- Temples: Side panels fully cover both temples without gaps.
- Cheeks: Guards rest firmly against cheekbones without pinching.
- Chin Strap: Snug under the jaw (one finger space), not pressing the throat.
- Vision: Peripheral vision is clear when looking left and right.
- Shake Test: Headgear moves with your skull when shaking or nodding.
Signs of a Bad Fit
Too Big: Rotates on impact, chin strap gaps, requires constant readjustment, blocks peripheral vision, or lifts at the back when tucking your chin.
Too Small: Pressure points on forehead/temples, restricted jaw movement, red marks after use, chin strap pulls against throat, or causes headaches.
Model Comparisons
STING Competition Approved Head Guard 2.0
The STING Competition Approved Head Guard 2.0 has an open-face design and a hook-and-loop fit system. STING lists sizes S through XL. Use the current chart for this exact model and check its adjustment on your head.
STING Orion Gel Headguard
The STING Orion Gel Headguard uses Neo Gel padding and an open-face profile. Compare its shape and coverage with the Competition model, using the Orion's own current sizing guidance rather than assuming it runs larger.

Adjustment Tips
- Rear Lacing (where fitted): Loosen fully, put on, and pull evenly from bottom to top until flush against the back of your head. Tie securely.
- Chin Strap: Fasten last. It should sit under your jawbone, snug enough for one finger space.
- Top Strap: Adjust to eliminate vertical play.
- Re-Check: Re-evaluate fit after warming up, and readjust if it moves or feels uncomfortable.
Recommendations by Skill Level
Beginner
Prioritize a secure fit and visibility. The STING Orion Gel Headguard is ideal, offering forgiving gel padding and confidence-boosting cheek coverage.
Amateur Competitor
STING lists the Competition Approved Head Guard 2.0 as World Boxing and England Boxing approved. Confirm this exact model is accepted for your event and category. Browse our amateur boxing equipment for more. For a full breakdown of the wider setup, read our complete boxing protective gear guide.
Advanced Fighter
Fit under sustained pressure is key. A well-adjusted headguard should feel like it disappears. The Hit N Move Air Armor Precision Headgear is a strong performance-focused alternative.
Break-In & Lifespan
The fit may settle with use, but there is no fixed break-in timetable that makes a painful or loose headguard suitable. Follow the model's instructions and have the fit checked before contact training.
Replace your headgear when adjustments no longer secure the fit, Velcro fails, foam flattens, or the shell cracks. Replace by condition rather than a fixed number of months.
Which Should You Order?
- Order the Competition Approved Head Guard 2.0 if: you need that exact approved model for your event, or its open-face profile suits your training and fits securely.
- Order the Orion Gel Headguard if: you want its gel-padded open-face design and its shape and sizing suit your head.
Between sizes? Follow the current model-specific guidance and ask for fitting help; there is no single up-or-down rule for every head shape.
