Getting the right Under Armour shin guard size ensures maximum protection and comfort. Measure from the top of your foot to just below your kneecap; most Under Armour adult sizing falls between 15″-17″, while youth sizes are typically 12″-14″. Always consult the specific product’s sizing chart for the most accurate fit.
Finding the perfect fit for your Under Armour shin guards can feel a bit tricky, especially when you’re just starting out with catcher’s gear. You want protection, but not so much that it feels bulky or restrictive. Too tight, and it’s uncomfortable; too loose, and it won’t protect you when you need it most. It’s a common hurdle for many young players and even seasoned veterans looking for an upgrade.
Don’t worry, though! Getting the right size is simpler than you think. We’ll break down exactly how to measure and choose the best fit so you can focus on the game, not your gear. Stick around, and we’ll guide you through every step to finding your ideal Under Armour shin guards.
Why Shin Guard Fit Matters So Much

As a catcher, your legs are on the front lines. They take foul tips, errant pitches, and the occasional collision. Properly sized Under Armour shin guards are your first line of defense. When they fit correctly, they stay put, offering consistent protection without digging in or sliding around. This means you can move freely, block pitches with confidence, and focus on making plays, all while feeling secure. An ill-fitting pair, however, can lead to discomfort, distraction, and worst of all, compromised safety. Imagine a foul ball hitting where your shin guard should be but isn’t because it shifted during a play – not a good scenario!
The technology behind modern shin guards, like those from Under Armour, aims to provide a balance of protection and mobility. This is achieved through specialized padding, sturdy outer shells, and adjustable straps. But all that innovation is for naught if the guard isn’t the right size for your leg. Let’s dive into how to make sure yours are just right.
Understanding Under Armour Shin Guard Sizing

Under Armour offers a range of shin guards designed for different levels of play, from youth leagues to the pros. While specific models might have slight variations, the core principle of sizing remains consistent: it’s all about measuring your leg to ensure the guard covers the critical areas effectively.
The Key Measurement: From Foot to Knee
The most crucial measurement for catcher’s shin guards is the length from the top of your foot to just below your kneecap. This ensures the guard covers your entire shin bone, which is essential for protection against foul balls and other impacts. Here’s how to get it right:
- Get a flexible measuring tape: A standard cloth tape measure works best.
- Wear your athletic shoes: The top of your shoe can influence where the guard rests.
- Stand up straight: Ensure your leg is straight and relaxed.
- Measure from the top of the shoe: Start the measurement at the very highest point where your shoe meets your leg.
- Measure to just below the kneecap: Your kneecap is the bony protrusion at the front of your knee. You want the measurement to end a little bit below the center of this kneecap. Think about where a direct impact would be most vulnerable.
- Have someone help if possible: It’s easier to get an accurate measurement with a second person.
Once you have this measurement in inches, you can compare it to Under Armour’s sizing charts. For context, most adult catcher’s shin guards are designed to fit legs measuring between 15 and 17 inches. Youth sizes often range from 12 to 14 inches. Remember, this is a general guideline; always check the specific chart for the model you’re interested in.
General Sizing Chart for Under Armour Catcher’s Shin Guards
Below is a typical sizing guide. Please note that specific product pages on the Under Armour website or retailer sites will have the most up-to-date and accurate charts for each model.
| Measurement (Inches from top of shoe to below knee) | Suggested Size | Typical Sizing Category |
|---|---|---|
| 12″ – 13″ | Youth Small/Medium | Youth |
| 13″ – 14″ | Youth Large | Youth |
| 15″ – 16″ | Adult Small/Medium | Adult |
| 16″ – 17″ | Adult Large/X-Large | Adult |
| 17″+ | Adult X-Large/XX-Large | Senior/Pro |
What About Calf and Thigh Width?
While leg length is the primary sizing factor, calf and thigh width do play a role in comfort and security. Most shin guards are designed with flexibility in mind, using adjustable straps to accommodate different leg shapes. However, if you have particularly muscular or slender legs, you might find some models fit more snugly or loosely than others.
- Adjustable Straps: Look for shin guards with multiple adjustable straps, often Velcro-based. This allows you to fine-tune the fit around your calf and shin.
- Padding: The padding should contour comfortably to your leg. If it feels like it’s pressing too hard on one area or leaving gaps, it might not be the right width.
- Inner Liner: Some shin guards have comfort liners. Make sure these don’t bunch up or feel too tight.
When trying on shin guards, if possible, mimic catcher’s stance. Bend your knees, adjust your position, and see how the guards move with you. They should feel secure and protective without restricting your ability to squat and move.
Beyond the Measurement: Features to Consider

Once you’ve got the sizing down, other features of Under Armour shin guards can impact your comfort and performance. It’s worth noting that Under Armour often integrates their patented technologies into their gear for better performance. For instance, their HeatGear® technology helps wick away moisture, keeping you cooler and drier during intense games, which is a huge plus for any catcher. Similarly, their focus on strategic padding and durable materials contributes to both protection and longevity.
Padding and Protection Levels
Under Armour offers different levels of padding. For younger players or those in rec leagues, standard padding might be sufficient. However, if you’re playing at a higher-impact level or are especially concerned about foul tips, consider models with enhanced padding in key areas, such as over the shin bone and around the ankle. Remember, more padding can sometimes mean a bulkier guard, so the right size becomes even more critical to avoid feeling weighed down.
Ventilation and Comfort
Catching involves a lot of movement and can get hot! Shin guards designed with ventilation can make a big difference. Look for features like strategic vents or breathable materials. Under Armour often incorporates airflow channels into their designs. A comfortable inner lining is also key to prevent chafing and keep you focused during long innings.
Durability and Materials
Shin guards need to be tough. Under Armour generally uses high-quality plastics and robust padding. Check reviews for insights into how well different models hold up over time. The shell should be strong enough to deflect balls, and the straps should maintain their grip through repeated use. The integrated technologies often play a role here too, ensuring materials perform as expected under game conditions.
How to Properly Fit Your Under Armour Shin Guards
You’ve got your measurements, you’ve picked out some potential models, and now it’s time to try them on. This is where you confirm your research and make sure the fit is perfect. We’re going to go through the steps.
Step-by-Step Fitting Process
- Put on your catcher’s leg guards: Start with one leg. Slide the shin guard over your foot and up your leg.
- Secure the straps: Fasten the straps, usually starting from the bottom and working your way up (or as indicated by the manufacturer). Make sure they are snug but not painfully tight. You should be able to slip a finger or two between the strap and your leg.
- Stand and squat: Stand up tall, then assume a catcher’s squat. How do the shin guards feel? Do they stay in place? Do they dig into your knees or shins?
- Check for coverage: Look in a mirror or have someone else check. Does the guard cover your entire shin bone, extending from just above your shoe to below your kneecap? Is there any exposed area that looks vulnerable?
- Assess mobility: Can you move freely? Can you comfortably bend your knees to squat and get up? Shin guards should protect without hindering your natural movement.
- Test for slippage: Wiggle your leg. Jump up and down a couple of times. Do the shin guards slide down your leg? A little bit of movement is sometimes expected, but significant slippage indicates a poor fit or that the straps aren’t tight enough.
- Repeat for the other leg: Ensure the fit is consistent on both sides.
It’s also a good idea to wear your catcher’s pants over the shin guards if you have them handy. This gives you a realistic sense of how the gear will feel during a game.
Common Shin Guard Sizing Mistakes to Avoid
Even with careful measurement, some common pitfalls can lead to choosing the wrong size. Here are a few to watch out for:
- Over-reliance on general charts: As mentioned, always check the specific chart for the model you are buying. Even within Under Armour, different lines might have slightly different sizing.
- Not accounting for snugness: While you want them secure, over-tightening straps can cut off circulation and be incredibly uncomfortable. Aim for snug, not strangling!
- Ignoring mobility: A perfectly sized guard that restricts your ability to squat properly is not the right guard.
- Not considering thickness of socks/pants: If you wear very thick socks or plan to wear bulky pants over your guards, this can slightly affect the perceived fit.
- Buying too big “to grow into”: While kids grow fast, shin guards that are too large are a safety hazard now. It’s better to get a comfortable, protective fit for their current size and adjust later.
Youth vs. Adult Sizing Differences
The primary difference between youth and adult Under Armour shin guards lies in their overall length and sometimes width. Youth sizes are designed for smaller individuals with shorter legs. Adult sizes cater to a broader range, and therefore, might offer a wider array of lengths and widths. It’s not just about shorter legs; youth gear is often designed with slightly less bulky padding for younger, less powerful players, though protection is still paramount.
When fitting youth shin guards, the same principles apply: measure from the top of the shoe to just below the kneecap. However, remember that children are still growing. While getting a good fit is crucial for safety, parents might look for models with ample adjustment room. For example, the Little League official equipment guidelines emphasize proper fit for safety, a principle that extends to all age groups.
Ensuring a Secure Fit Through Adjustable Straps
Under Armour shin guards typically feature multiple adjustable straps. These are your best friends for achieving a customized fit. Most are made of durable Velcro that holds well, even when sweaty.
- Top Strap: This strap is key for preventing slippage down the leg. It should be snug enough to hold the guard up without digging into your knee.
- Middle Strap(s): These help secure the guard around your calf. Adjust them to a comfortable tightness that doesn’t restrict blood flow.
- Bottom Strap: This strap helps keep the lower part of the guard in place and ensures it doesn’t shift outward.
When adjusting, try the “finger test”: you should comfortably be able to slip one or two fingers between the strap and your leg. This ensures it’s secure without being too constricting. Always ensure all straps are securely fastened before stepping onto the field.
When to Consider Professional Fitting or Different Models
If you’re struggling to get a proper fit with standard Under Armour models, or if you have unique leg anatomy (e.g., very large calves, very thin legs, or specific knee issues), it might be worth exploring:
- Higher-End Models: Sometimes, more expensive or professionally oriented shin guards offer better adjustability or different shapes.
- Brands with Different Fits: While Under Armour is great, other brands might have a slightly different cut or fit philosophy that suits you better.
- Consulting a Coach or Pro Shop: An experienced coach or someone at a dedicated baseball equipment store can often offer personalized advice and help you try on various options. They understand the nuances of gear fit better than anyone.
- Custom Options (Rare): For very specific needs, custom gear is an option, though this is usually reserved for elite players.
Remember, the goal is comfort, protection, and unrestricted movement. If you’re not achieving all three, keep looking.
FAQ: Under Armour Shin Guard Sizing
Q1: How do I find the right size Under Armour shin guards for a youth player?
For youth players, measure from the top of their athletic shoe to just below the kneecap. youth sizes typically range from 12 to 14 inches. Always check the specific product sizing chart on the Under Armour website or retailer’s page. Ensure the guards are secure but not too tight, allowing room to grow without compromising safety.
Q2: What is the most important measurement for catcher’s shin guards?
The most critical measurement is the length from the top of your shoe to just below your kneecap. This determines how much of your shin is covered, which is vital for protection against foul balls and impacts.
Q3: Can I use my regular pant inseam measurement for shin guards?
No, your pant inseam measurement is not suitable for shin guard sizing. Shin guard sizing is specific to the length of your leg from ankle to knee, not your overall pant length.
Q4: My shin guards feel a bit loose. What should I do?
First, ensure you’ve properly adjusted all the straps and they are as snug as comfortable. If they still feel loose or slide down, you might need a smaller size. Check the manufacturer’s sizing chart again, and consider if the width of the guard is also an issue for your leg shape.
Q5: Should Under Armour shin guards be tight or loose?
Under Armour shin guards should be snug and secure, but not uncomfortably tight. They need to stay in place during play without restricting circulation or movement. You should be able to comfortably squat and move. Aim for a fit where you can slip a finger or two under the straps.
Q6: How much gap should there be between my shin guard and my cleat/shoe?
The measurement usually starts from the top of your shoe. This means the guard should sit just above your shoe, with no significant gap. The bottom edge of the shin guard should extend down to almost cover the top of your foot, integrating seamlessly with your shoe.
Q7: Are there different sizing standards for different Under Armour shin guard models?
While Under Armour shares general sizing principles, there can be slight variations between different models or lines of shin guards. It is always best practice to refer to the specific sizing chart provided for the exact model of shin guards you intend to purchase.
