D&D 5e Armor Types Explained

Introduction to Armor in D&D 5e

In Dungeons & Dragons 5th Edition, armor represents a character’s active defenses and readiness for danger. It shapes survivability, mobility, and role identity by defining who can wear what and how well they withstand blows. Understanding armor types in D&D 5e is essential for building characters that remain effective from low-level skirmishes to high-tier campaigns. This guide explains armor categories, AC calculations, special rules, and practical tradeoffs, using only rules from the Player’s Handbook and core supplements.

Armor Categories and AC Calculation

D&D 5e organizes armor into light, medium, and heavy categories, each with distinct base AC values, proficiency requirements, and restrictions. A character’s AC is determined by armor, shield, and ability modifiers as specified by their equipped gear. Class proficiencies govern which armors a character can use without penalty; wearing non-proficient armor can impose disadvantage on certain checks and movement features. These categories also interact with class design and playstyle, influencing survivability, mobility, and flexibility in and out of combat.

Light Armor

Light armor emphasizes mobility and flexibility, making it ideal for rogues, monks, and some spellcasters. It typically allows stealth and ranged-dexterity-based actions with minimal restriction. Common examples include the following:

• Padded (AC 11 + Dex mod)
• Leather (AC 11 + Dex mod)
• Studded leather (AC 12 + Dex mod)

Light armor generally imposes no disadvantage on stealth checks and supports high Dexterity builds focused on evasion and positioning.

Medium Armor

Medium armor balances protection and mobility, suitable for fighters, rangers, and swashbuckling rogues. It provides solid AC without heavy encumbrance. Common examples include the following:

• Scale Mail (AC 14 + Dex mod, max Dex 2)
• Breastplate (AC 14 + Dex mod, max Dex 2)
• Half Plate (AC 15 + Dex mod, max Dex 2)

Medium armor often requires Strength checks for heavier variants and may restrict certain class features that rely on unimpeded movement.

Heavy Armor

Heavy armor delivers high protection at the cost of speed and flexibility. It is typically worn by frontline fighters and paladins who can leverage durability in extended engagements. Common examples include the following:

• Ring Mail (AC 14)
• Chain Mail (AC 16)
• Splint (AC 17)
• Plate (AC 18)

Heavy armor usually imposes disadvantage on Stealth and may require checks to maintain speed or mount/dismount from vehicles.

Shield Mechanics and Alternatives

Shields provide a universal AC bonus and can be combined with many armor types, significantly increasing survivability. However, using a shield requires a free hand and may limit access to two-weapon fighting or certain interactions. In cases where shields are unavailable or impractical, alternative options include the following:

• Shield spell (magical defense without a physical shield)
• Barkskin (natural armor enhancement)
• Mage Armor (fixed light armor AC)
• Unarmored defense features (e.g., Monk, Barbarian)

These alternatives allow characters to maintain defensive capabilities when traditional armor or shields are unsuitable.

Special Rules and Interactions

Several game features interact with armor, creating strategic tradeoffs between defense, mobility, and role requirements. Disadvantage on Stealth checks is common with heavier armor, while some class features, like a Monk’s Unarmored Movement, impose automatic restrictions on armor types. Carrying excessive bulk can also affect athletic checks, initiative, and social perception. Understanding these nuances helps players optimize builds for specific encounters and long-term campaigns.

Armor Properties, Costs, and Availability

Armor in D&D 5e has defined costs, weights, and availability, which influence campaign planning and resource management. While basic armor is widely available in settlements, specialized gear may require travel, downtime, or quests to obtain. Enchanted variants can provide additional defenses or resistances, often reflecting rarity tier and technological/magical sophistication. These properties should align with campaign tone and balance expectations.

Core Armor Reference

The following table summarizes standard armor attributes from the Player’s Handbook. It includes base AC, weight, cost, proficiency requirement, and typical use cases for quick reference at the table.

Tactical Tradeoffs by Playstyle

Choosing an armor type should reflect your character’s intended role and campaign context. A Monk pursuing mobility will avoid heavy restrictions, while a Fighter anchoring the frontline can leverage plate’s durability. Spellcasters balancing physical defense with spellcasting flexibility may prefer light or magical solutions. Consider the following when selecting armor:

• Dexterity synergy: Light and some medium armors cap Dexterity bonuses, affecting AC scaling.
• Stealth compatibility: Heavy armor often imposes disadvantage on Stealth; lighter options do not.
• Encumbrance and endurance: Heavier armor reduces movement and can impose exhaustion thresholds.
• Resource availability: Rare armor may require downtime, quests, or significant wealth to acquire.

By aligning armor choice with class strengths and narrative goals, players can maintain effectiveness and immersion across varied challenges.
