How to Size Armor Plates

How to Size Armor Plates

Choosing the right size armor plates is crucial for optimal protection and comfort. Armor plates come in various sizes to accommodate different body types and carrier configurations. The most common sizes are:


Size Dimensions
Small 8.75" x 11.75"
Medium 9.5" x 12.5"
Large 10.25" x 13.25"
Extra Large 11" x 14"

It's essential to measure your torso and consult the manufacturer's sizing chart to determine the best fit for your body armor setup.

Factors to Consider When Sizing Armor Plates

Several factors come into play when sizing armor plates:

  1. Body Type and Size
  2. Plate Carrier Style and Configuration
  3. Intended Use and Threat Level
  4. Mobility and Comfort Requirements

Take the time to assess your specific needs and preferences to ensure you select the optimal armor plate size for your situation.

Measuring Your Torso for Armor Plates

To determine your armor plate size, you'll need to measure your torso:

  1. Measure from the notch in your clavicle (collarbone) to the bottom of your rib cage.
  2. Add 2-4 inches to this measurement to allow for adequate coverage.
  3. Compare your measurement to the manufacturer's sizing chart to find the appropriate plate size.

Remember, a proper fit is key to maximizing protection and minimizing discomfort during extended wear.

Plate Carrier Compatibility and Sizing

Your plate carrier choice will also impact armor plate sizing. Different carriers accommodate specific plate sizes, so it's crucial to ensure compatibility. Consider these factors:

  • Carrier style (tactical, low-profile, covert)
  • Plate pocket dimensions
  • Adjustability and customization options
  • Load-bearing capacity and weight distribution

Consult the carrier manufacturer's guidelines and specifications to ensure a seamless integration with your chosen armor plates.

Balancing Protection and Mobility

Striking the right balance between protection and mobility is essential when sizing armor plates. While larger plates offer more coverage, they can also impede movement and add weight. Consider your operational needs and environment:

  • Threat level and likely engagement distances
  • Activity level and agility requirements
  • Climate and temperature considerations
  • Duration of wear and fatigue factors

Select a plate size that provides adequate protection without compromising your ability to perform effectively.

Front and Back Plate Size Variations

In some cases, you may opt for different sized front and back plates. This configuration can provide enhanced protection for vital organs while reducing overall weight and bulk. Common variations include:

  • Larger front plate for heart and lung protection
  • Smaller back plate for increased mobility
  • Angled or asymmetric plates for specific coverage needs

Assess your unique requirements and consult with industry professionals to determine if mixed plate sizes are appropriate for your setup.

Side Plate Sizing and Placement

Side plates offer additional protection for the torso's lateral aspects. When incorporating side plates, consider these factors:

  • Plate shape and curvature for a contoured fit
  • Plate thickness and weight for comfort and mobility
  • Carrier compatibility and attachment methods
  • Placement and adjustment for optimal coverage

Ensure your side plates integrate seamlessly with your carrier and main armor plates for comprehensive protection.

Armor Plate Material and Thickness Considerations

Armor plate material and thickness also influence sizing decisions. Different materials offer varying levels of protection, weight, and durability:

Material Protection Level Weight Thickness
Steel III+ to IV Heaviest 0.25" to 0.3"
Ceramic III to IV Moderate 0.7" to 1"
Polyethylene II to III+ Lightest 0.9" to 1.2"

Consider your threat environment and personal preferences when selecting armor plate material and thickness, as they directly impact sizing options.

Trying On and Adjusting Armor Plates

Once you've selected your armor plates, it's essential to try them on and make any necessary adjustments:

  1. Insert plates into carrier pockets
  2. Don carrier and secure straps and closures
  3. Check for gaps, shifting, or discomfort
  4. Make incremental adjustments to achieve a snug, stable fit
  5. Perform range of motion and mobility tests
  6. Fine-tune plate placement and carrier settings as needed

A well-fitted armor plate setup maximizes protection, comfort, and performance in the field.

Maintaining and Replacing Armor Plates

Regular maintenance and timely replacement of armor plates are crucial for ongoing safety and effectiveness:

  • Inspect plates for damage, cracks, or deformities
  • Clean and store plates according to manufacturer guidelines
  • Replace plates after significant impacts or per expiration dates
  • Rotate plate inventory to ensure consistent protection

Invest in quality armor plates from reputable manufacturers like Spartan Armor Systems and Shellback Tactical for reliable, long-lasting protection.
