Frequently Asked Questions
Where is the official Warhammer 40K base-size update?
The official Warhammer Event Companion checked for this guide includes a Base Size Guide marked June 2026. The guide starts on the document’s printed page 54 and groups entries by faction. For later revisions, begin at Warhammer Community downloads. Our check on October 9, 2026 does not establish a separate October base-size change list. Keep the document date beside your notes so another player can reproduce your lookup. A newly circulating screenshot is not, by itself, evidence that every base in an army has changed.
Do all Space Marines use the same base size?
Must I rebase every older model before playing?
How can I explain a rebasing change in a video?
