What is CoC War Weight?
In Clash of Clans (CoC), war weight is a hidden metric that the game uses to balance matchmaking for Clan Wars. Essentially, it represents the overall offensive and defensive strength of your base. A higher war weight means your base is considered stronger, influencing the matchmaking algorithm to pair your clan against an opponent clan with a similar total war weight. Understanding your CoC war weight is crucial for strategic planning, allowing you to make informed decisions about when to upgrade defenses, which troops to prioritize, and how to manage your base's development to achieve favorable matchups. Many players focus on offensive upgrades to keep their war weight lower relative to their offensive power, leading to easier wars.
Who Should Use a CoC War Weight Calculator?
Any Clash of Clans player involved in Clan Wars can benefit from using a CoC war weight calculator. This includes:
War-focused players: To optimize their base progression for competitive warring.
Clan Leaders and Co-Leaders: To guide their clan members on upgrade priorities and ensure balanced base development across the clan.
Newer players: To understand the long-term implications of their upgrade choices and avoid developing a "rushed" base that has high defense weight but low offensive power.
Players looking to improve war performance: By understanding how their base contributes to the clan's overall war weight, they can make strategic decisions to balance offense and defense.
Common Misconceptions about CoC War Weight
Several myths surround CoC war weight. One common misconception is that upgrading defenses always significantly increases war weight. While defenses do add weight, the game's algorithm often places a higher emphasis on offensive upgrades and town hall level. Another myth is that war weight is the *only* factor in matchmaking; other elements like clan experience and win streaks also play a role, though war weight is the primary driver. Finally, some believe that "turtling" (maxing defenses before offense) is the best strategy; however, for war performance, a strong offense is generally more valuable, making the concept of war weight management critical.
CoC War Weight Formula and Mathematical Explanation
The exact CoC war weight formula is proprietary and subject to change by Supercell. However, community research and analysis have provided a strong understanding of the contributing factors. This CoC war weight calculator uses a widely accepted model that approximates the calculation.
Step-by-Step Derivation (Simplified Model)
The total war weight is a sum of offensive and defensive components, with additional modifiers. Our calculator breaks it down as follows:
Base Defense Weight: This is influenced by the value of all defensive structures (Cannons, Archer Towers, etc.), traps, walls, and the Town Hall itself. Higher level defenses contribute more weight.
Offensive Strength: This is primarily driven by the total capacity of your Army Camps, the level of your Laboratory (which dictates troop and spell upgrade potential), and the combined levels of your Heroes.
Siege Machines & Pets: The presence and level of Siege Barracks and the Pet House add significant weight, reflecting their tactical importance and resource investment.
Loot Cart Approximation: The estimated value of the loot cart when you lose a raid is used as a proxy for your base's defensive deterrent value. A higher potential loot cart suggests a more valuable target, thus contributing to defensive weight.
The CoC war weight calculator combines these elements. For instance, a higher Town Hall level inherently increases base weight. Offensive upgrades (like troops researched in the Laboratory or heroes) increase offensive power and thus offensive weight, often perceived as more beneficial for war performance than solely defensive upgrades.

Practical Examples (Real-World Use Cases)
Let's examine how different base progressions affect CoC war weight using our calculator.
Example 1: Maxed Town Hall 10 Attacker
Consider a player at Town Hall 10 who focuses heavily on offense:
Inputs:
Estimated Loot Cart Value: 200,000
Army Camp Capacity: 220
Laboratory Level: 8
Combined Hero Levels: 60 (AQ 30, BK 30)
Siege Barracks Level: 1
Pet House Level: N/A (unlocks at TH12)
Calculator Output (Estimated):
Main Result (Total War Weight): ~75,000
Offensive Weight: ~35,000
Defensive Weight: ~30,000
Base Weight Approximation: ~10,000
Interpretation: This player has a relatively high offensive weight compared to their defensive weight. This is generally favorable for war matchmaking, as the algorithm might pair them against an opponent with a similarly strong offense, potentially allowing for more successful attacks within the clan war.
Example 2: Town Hall 11 Focused on Defense
Now, consider a player at Town Hall 11 who has upgraded defenses significantly but neglected offensive power:
Inputs:
Estimated Loot Cart Value: 400,000
Army Camp Capacity: 240
Laboratory Level: 7
Combined Hero Levels: 40 (AQ 20, BK 20)
Siege Barracks Level: 2
Pet House Level: N/A
Calculator Output (Estimated):
Main Result (Total War Weight): ~90,000
Offensive Weight: ~25,000
Defensive Weight: ~50,000
Base Weight Approximation: ~15,000
Interpretation: This player has a much higher total war weight, largely driven by their strong defenses and higher Town Hall level. However, their offensive weight is disproportionately low. This could lead to difficult war matchups where opponents have stronger offensive capabilities, making it harder to secure 3-star victories. This illustrates why prioritizing offensive upgrades is often recommended for competitive CoC war weight management.

Key Factors That Affect CoC War Weight Results
Several factors significantly influence your base's CoC war weight. Understanding these helps in strategic decision-making:
Town Hall Level:
This is arguably the single biggest contributor to base weight. Each new Town Hall level introduces new defenses, buildings, and significantly increases the inherent weight of the base itself. Upgrading your Town Hall should always be accompanied by offensive upgrades to compensate.
Defensive Structure Levels:
While not as impactful as the Town Hall level itself, upgrading defenses like Cannons, Archer Towers, Wizard Towers, Inferno Towers, and Eagle Artillery adds substantial weight. Prioritizing offense over defense *early* in a Town Hall level helps manage this.
Hero Levels:
Heroes are crucial for both offense and defense. Their levels contribute significantly to your offensive power and their hitpoints/abilities add defensive weight. High-level heroes are essential for competitive warring, and their weight contribution is generally considered 'good' weight.
Troop and Spell Levels:
The research of troops and spells in the Laboratory directly impacts your offensive capabilities. Higher-level troops mean stronger armies capable of achieving more stars. The overall 'potential' of your offensive army, dictated by lab research, is a major component of offensive war weight.
Army Camps and Resource Storages:
The total capacity of your Army Camps determines how many troops you can deploy, directly affecting offensive power. While less impactful than troop levels or heroes, they do contribute. Storages, while less directly impactful on war weight, indicate resource accumulation which often correlates with upgrade progress.
Walls:
Each wall segment has a weight, and upgrading them to higher levels (e.g., Diamond Walls at TH14) adds a considerable amount of weight, especially when many are upgraded. This is often considered 'heavy' or less efficient weight compared to offensive upgrades.
Siege Machines and Pets:
The introduction of Siege Barracks and Pet House has added new layers to war weight. These powerful additions increase both offensive and defensive strategic value, contributing meaningfully to the overall war weight calculation.
Frequently Asked Questions (FAQ)
Q1: Is war weight the only factor in Clan War matchmaking?
No, war weight is the primary factor, but Supercell also considers other elements like clan experience level, recent war performance (win streaks/losses), and potentially player activity to ensure a balanced matchmaking experience.
Q2: Should I stop upgrading my defenses to lower my war weight?
Not necessarily. While lowering weight can help, a severely under-leveled defense makes your base an easy target, hurting your clan's defensive stars. The key is balance: prioritize offensive upgrades (troops, heroes, camps) first, then upgrade defenses strategically, especially after reaching a new Town Hall level.
Q3: Does upgrading walls increase my CoC war weight significantly?
Yes, upgrading walls, especially to higher levels, contributes a substantial amount of weight. While they improve defensive capabilities, they are often considered less 'efficient' weight compared to offensive upgrades for winning wars.
Q4: What is considered "rushed" in Clash of Clans?
A "rushed" base is one where the Town Hall level is significantly higher than the levels of the offensive troops, heroes, and army camps. These bases often have high defensive weight but struggle offensively, leading to poor war performance.
Q5: How does the Laboratory level affect war weight?
The Laboratory level dictates the maximum level your troops and spells can reach. A higher Laboratory level enables more powerful armies, thus increasing your offensive potential and contributing positively to your offensive war weight.
Q6: Can I see my exact war weight in the game?
No, Clash of Clans does not display your exact war weight publicly. It's a hidden metric used by the matchmaking algorithm. Calculators like this one provide estimates based on community research.
Q7: What is the best strategy for managing war weight?
The general consensus is to prioritize offensive upgrades (troops, heroes, army camps) to match your Town Hall level. Upgrade defenses strategically, often 'in sync' with your offensive progress or after achieving key offensive milestones.
Q8: Do Clan Games and Season Challenges affect war weight?
Not directly. While rewards from these events might provide resources or books that help speed up upgrades, the activities themselves don't alter your base's war weight. The weight is determined by the actual level of your buildings, troops, and heroes.
Q9: How important are Siege Machines for war weight?
Siege Machines are very important. They offer significant strategic advantages in both offense and defense and have a noticeable impact on your overall war weight calculation. Upgrading your Siege Barracks and unlocking/leveling Siege Machines is crucial for competitive play.
