How to use this tool

Prefer the Lineup Builder for real vehicles. This slider remains for quick mental math.

Quick mental math for lineup BR spread and the ±1.0 matchmaking window. For real vehicles and share links, prefer the Lineup Builder.

  • Your top BR vehicle usually sets who you fight.
  • A 0.3–0.7 spread is easier to play consistently than a full 1.0 gap.

Limitations

  • • Does not simulate full matchmaker rules, uptiers, or downtiers case-by-case.
  • • Arcade and custom events may use different spreads.

BR spread in Realistic Battles

Enter your highest and lowest vehicle BR. The chart shows spread and a simple matchmaking window around the top rating. A tidy 0.3–0.7 spread is usually easier to play than a full 1.0 clown-car lineup.

Arcade and event queues can use different rules. Keep air and ground checks separate. When you are ready to pick real tanks, switch to the Lineup Builder so repair and soft spawns appear too.

Frequently asked questions

Is Lineup Builder better?
For anything beyond a quick check, yes — it uses real vehicles from the cache and shareable URLs.
Does ±1.0 always apply?
It is the common RB mental model, not a guarantee for every mode or event.
