What this data covers

This page answers which base size and shape ship with the current, verifiable product. Games Workshop does not publish a single permanent base-size chart, so each record here cites the official Warhammer Event Companion base size guide or two independent hobby references. Whether an event accepts older, alternative, or custom bases is decided by the event organizer's rules — this page makes no tournament-legality claims.

How records are verified

Every record lists its own sources. Verified means an official Games Workshop document states the size. Verified (two references) means the official table does not cover the unit, and two independent hobby references agree. Incomplete means we could not confirm the size from acceptable sources. Conflict means sources disagree about the same model version — no single answer is shown.
