Armor has long been a symbol of strength, protection, and warrior pride throughout history. From the lightweight chainmail worn by early medieval soldiers to the imposing plate armor of jousting knights, the weight of a suit of armor has always been a topic of fascination. The idea of a warrior clad head to toe in heavy, clanking metal seems like something out of an epic saga.
But the reality of armor weight is far more nuanced. How much does a suit of armor really weigh? The answer depends on many factors, including the type of armor, the materials used, and the era in which it was made.
In this article, we will delve deep into the different types of armor, their weight, and the factors that influence it. We will also explore the evolution of armor, its practical applications, and its cost.
What Is A Suit of Armor?
A suit of armor is an ensemble of protective clothing worn by warriors, soldiers, or knights in battle. Its primary function was to provide defense against various weapons, from swords and arrows to maces and axes. Armor came in many forms, with each part designed for specific protection. These parts included the helmet, breastplate, gauntlets, greaves, and the chausses (armor for the legs). Early forms of armor were crafted from natural materials like animal hides, but as technology evolved, so did the materials used in the construction of armor. Over time, metal became the primary material for armor, with iron and steel being the most common choices.
The Craft of Armor Making
The creation of armor was no easy feat. It involved complex craftsmanship, requiring the skills of blacksmiths, armorers, and artisans. Making a full suit of armor often took weeks, if not months, to complete, depending on the complexity and customization. The process began with the selection of materials. Blacksmiths would heat the metal to high temperatures, hammering it into shape and then cooling it to harden the metal. For more advanced designs, artisans would use techniques such as engraving or etching to add decorative elements to the armor. Armorers also had to ensure that the pieces were not only functional but also comfortable and flexible enough to allow the wearer to move.
The Purpose of Armor
Armor served many purposes beyond protection. It was also a symbol of the wearer’s social standing and wealth. Knights and nobility often had armor specially crafted to display their heraldic symbols or to set them apart from lower-ranking soldiers. In battle, armor was an essential tool that could mean the difference between life and death, while in ceremonial contexts, it was a symbol of honor, tradition, and power.
Types of Suits of Armor
Over the centuries, different types of armor were developed to suit the changing needs of warriors and their evolving combat strategies. The key types of armor that have shaped the history of warfare include chainmail, plate armor, lamellar armor, and jousting armor.
1. Chainmail Armor
Chainmail, one of the earliest forms of armor, was composed of interlinked metal rings. These rings were woven together in a way that created a flexible yet strong material capable of absorbing the force of slashing attacks. Chainmail armor was used by foot soldiers, knights, and even Viking warriors. Its primary advantage was its flexibility, allowing the wearer a great degree of mobility.
- Weight: Chainmail armor typically weighs between 20 to 30 pounds (9-14 kg) for a standard shirt. This made it much lighter than later forms of armor.
- Structure: The armor consists of thousands of small metal rings woven into a mesh. While flexible, it provided less protection against blunt-force trauma.
- Protection: Chainmail offered excellent protection against cutting weapons such as swords and axes but was less effective against stabbing or thrusting attacks, such as those from a spear or a pointed sword.
2. Plate Armor
Plate armor represents one of the most iconic forms of medieval combat protection. It emerged in the 15th century and consisted of large, solid metal plates that covered most of the body. These plates were often riveted together and shaped to fit the contours of the human body, providing comprehensive protection from both cutting and stabbing weapons.
- Weight: Full-body plate armor typically weighed between 45 to 55 pounds (20-25 kg), though heavier versions, especially those designed for jousting, could exceed 100 pounds (45 kg).
- Structure: Plate armor was constructed from large, interlocking metal plates that provided near-complete coverage of the body. The most vulnerable areas, such as the chest and limbs, were heavily protected by thicker plates.
- Protection: Plate armor offered excellent protection from cutting, thrusting, and even blunt-force trauma. Its rigid structure made it effective at absorbing the impact of weapons like swords and axes. However, its rigidity could restrict movement, especially in battle scenarios that required agility.
3. Lamellar Armor
Lamellar armor, consisting of small rectangular plates, was a popular choice in East Asia, particularly among the Samurai and Mongol warriors. This type of armor was often crafted by sewing the small plates together into overlapping rows, which provided a balance of flexibility and protection. Unlike the rigid plate armor, lamellar armor allowed the wearer more freedom of movement.
- Weight: Lamellar armor generally weighs between 30 to 45 pounds (14-20 kg), depending on its design and the materials used.
- Structure: The overlapping plates were usually made from metal or hardened leather and sewn together. This structure allowed the armor to flex with the wearer’s movements, which was essential for archers and cavalry.
- Protection: Lamellar armor provided solid protection against slashing attacks, but it was not as effective at defending against stabbing or thrusting strikes. The flexibility of the armor made it well-suited for mounted warriors and archers.
4. Jousting Armor
Jousting armor was designed specifically for tournament combat, where knights would engage in one-on-one jousts. This type of armor was reinforced to withstand the immense forces generated during a jousting match, especially the impact of a lance striking the wearer. Unlike battlefield armor, jousting armor was not intended for extended wear or mobility in a combat situation.
- Weight: Jousting armor could weigh anywhere from 70 to 100 pounds (32-45 kg), depending on the level of reinforcement.
- Structure: Jousting armor was thicker and more rigid than standard plate armor, with additional padding and reinforcements in key areas. It included large helmets, full breastplates, and reinforced gauntlets and greaves.
- Protection: Jousting armor was designed to absorb the immense impact from lances during tournaments. Its primary function was to protect the knight from blunt-force trauma, but it was less suited for actual battle where more mobility was required.

How Much Does A Suit of Armor Weigh?
The weight of a suit of armor varies significantly depending on the type, materials, and intended use. Armor designed for combat generally weighs more due to the added protection it provides. For example, plate armor, designed to protect the wearer in battle, is typically much heavier than chainmail, which was primarily intended to protect against cutting weapons.
- Chainmail Armor: A standard shirt of chainmail weighs between 20 to 30 pounds (9-14 kg). It is one of the lighter forms of armor.
- Plate Armor: Full-body plate armor generally weighs between 45 to 55 pounds (20-25 kg), though jousting armor can exceed 100 pounds (45 kg) due to added reinforcements.
- Lamellar Armor: Depending on the design and coverage, lamellar armor typically weighs between 30 to 45 pounds (14-20 kg).
- Jousting Armor: The heaviest form of armor, jousting armor, can weigh up to 100 pounds (45 kg), designed for specific use in tournaments rather than battlefield combat.
The weight of the armor can also vary based on the wearer’s size, with armor often tailored to fit individual soldiers. Custom-made armor may be lighter or heavier, depending on the materials chosen and the level of protection needed.

Basics of Armor Weight
The weight of a suit of armor is determined by several factors: the materials used, the design of the armor, and the intended use. Metal armor, especially steel and iron, is generally much heavier than armor made from lighter materials such as aluminum or composite materials. Armor designed to offer full-body protection tends to be heavier, as it must cover more surface area and protect vital organs. Furthermore, the purpose of the armor plays a key role in determining its weight. Combat armor, which needs to provide maximum protection, is generally heavier than ceremonial armor, which may prioritize appearance and style over full protection.
Factors Influencing Armor Weight
Several factors contribute to the overall weight of armor, including:
- Material Composition: Heavier metals such as steel increase the weight of armor, while materials like aluminum and modern composites are used to create lighter armor. For example, plate armor made entirely from steel will weigh significantly more than plate armor with aluminum reinforcements.
- Design and Articulation: Armor that is designed with more articulated joints or additional plates to improve mobility and protection will naturally be heavier. Conversely, armor that is simpler in design may be lighter but offer less overall protection.
- Purpose and Usage: Combat armor is usually heavier than ceremonial armor, as it is designed to withstand real-world weapons and impacts. In contrast, ceremonial armor is often designed for display and may be lighter to allow the wearer to move freely.
- Era and Region: Armor from different time periods and regions can vary in weight. Medieval armor, for instance, is generally heavier than modern tactical body armor, which benefits from advances in lightweight, high-performance materials like Kevlar.
Why Armor Weight Matters
The weight of a suit of armor is more than just a number; it has a direct impact on the wearer’s ability to function effectively. Armor that is too heavy can hinder the wearer’s movement, stamina, and speed, making it difficult to perform in battle or during physical activities such as jousting. On the other hand, armor that is too light may fail to provide adequate protection, leaving the wearer vulnerable to injury.
Choosing the right balance between weight and protection is essential. Soldiers, knights, and warriors needed to wear armor that was both effective in combat and practical for extended periods of use. This balance has evolved over time, as advancements in metallurgy, design, and materials science have allowed armor to become lighter and more protective.
What to Consider When Choosing Armor Based on Weight
When selecting a suit of armor, it is important to consider several factors based on weight:
- Purpose: Are you choosing armor for battle, a ceremonial occasion, or a reenactment? Armor for combat needs to be heavier to offer adequate protection, while ceremonial armor may be lighter for ease of movement.
- Fit: Properly fitted armor distributes weight evenly, reducing strain on the wearer. Poorly fitted armor can cause discomfort and limit mobility.
- Mobility: Consider how much freedom of movement you need. If you require agility, such as in fencing or jousting, lighter armor is preferable.
- Endurance: The weight of armor can significantly affect how long a wearer can stay active. For prolonged use, you’ll need armor that strikes a balance between protection and weight.
How Much Does Armor Cost?
Armor can be expensive, particularly when crafted by skilled artisans. The cost depends on the type of armor, the materials used, and whether the armor is customized for a specific wearer. For example, a basic chainmail shirt might cost around $500, while a full suit of plate armor could range from $2,000 to $5,000 or more. Jousting armor, being more specialized and heavily reinforced, can exceed $10,000. Modern tactical body armor is typically priced between $500 and $3,000, depending on the level of protection required.
Standard Dimensions/Height of Armor in Different Regions
Armor is often tailored to the size of the wearer, but there are general standards based on regional traditions and time periods:
- European Armor: Typically designed for individuals ranging from 5’8″ to 6’0″ (173-183 cm).
- Samurai Armor: Designed for Japanese warriors, often larger to accommodate the traditional kimono worn underneath.
- Modern Tactical Armor: Adjustable sizes to fit a range of body types, with many modern suits offering customizable options for fit.
Applications and Uses of Armor
Armor has always had practical applications beyond battle. Some of the key uses include:
- Combat: Historically, armor was primarily designed for battlefield protection, offering defense against a variety of weapons.
- Ceremonial: Armor has long been a symbol of power, wealth, and status, often worn in royal courts or during public events.
- Modern Uses: Today, body armor is used by military forces, law enforcement, and security personnel for protection against bullets and shrapnel.
Conclusion
The weight of a suit of armor has evolved significantly over time, from the lighter, more flexible chainmail of early medieval warriors to the heavily reinforced plate armor worn by knights during the height of chivalry. While weight plays a key role in armor design, it is just one of many factors that armorers consider when crafting protection for warriors. The right armor offers a delicate balance between mobility and defense, ensuring that the wearer is protected while still being able to function effectively.
