Clan War Weight & Matchmaking Explained
What actually goes into matchmaking beyond Town Hall level, and why two similar-looking clans can still get mismatched.
It's not just Town Hall level
Clan War matchmaking looks at each clan's overall "weight" — a combination of Town Hall levels, hero levels, troop and spell levels, and wall levels across the roster — not Town Hall alone. Two clans with identical average Town Hall can still be meaningfully mismatched if one has significantly higher hero or lab levels than the other.
Supercell has never published the exact formula, and it's changed over the game's history, so treat "weight" as a real concept with a real effect on matchmaking, not a number you can calculate precisely yourself.
Why a 'fair' matchup can still feel lopsided
Matchmaking pairs clans by overall roster strength, not by which specific members show up to attack. If your clan's top 15 members are strong but the rest of your roster is comparatively weak, you can still get matched against a clan that's more evenly strong throughout — same average weight, different distribution, different war experience.
This is also why scouting the actual opponent roster matters more than trusting the matchmaking to guarantee an even fight member-for-member.
Scouting instead of guessing
Once a war starts, both rosters are visible — Town Hall levels, and (during the actual battle day) attack results as they happen. Comparing your roster's Town Hall distribution against the opponent's, member by member, tells you more about the real matchup than anything matchmaking weight can predict in advance.
This site's War Room does exactly that comparison for a real clan tag: your roster against a real opponent's, side by side, so war planning starts from actual data instead of a gut feeling about who's stronger.
