While the main rulebook makes it clear which base sizes are allowed for each troop type, a lot of people have still been asking which base size to use for each unit. As such, I have with the help of the community put together this document that lists all the "official" base size for every single character and unit in Warhammer 9th Edition. These base sizes have been written to take into account all official models from 6th ed to 8th ed, with some minor adjustments for playability.
Base sizes are either square (like 20x20) or round/oval (like 25). In case the square bases is a rectangle (such as 25x50), use the first number for the model's front, and the second number for the model's flanks. In case you use oval bases, the number indicates the length of the base at its longest point. All base sizes are in mm.
Note that these base sizes are the considered the correct bases for the game. Larger or smaller base sizes should preferably be agreed upon with your opponent, but using larger base sizes than those listed should for the most part be considered fair game. In case you find any of these base sizes to be incorrect, feel free to feedback it at our Discord group, and it will be looked over for possible revision.
