Guide to 40k bases


When it comes to scratch-building, kit-bashing and deep conversions it is often necessary to know a size of a base the finished model is supposed to be put on. While it wasn't a big problem up to a while ago, many recent GW models use unusual (and often unique) bases. Thus I've had a feeling that some king of basing guide could be useful. Maybe some fellow hobbyists might find this helpful as well. So let's see what each base is used for.

This is a living article: I update it as new releases hit the shelves.

Latest update - 18.03.2024

INCONSISTENCIES


It should be noted that GW doesn't take the matter of basing their models as seriously as some competition-oriented hobbyists do, especially when alternate versions of GW models are released by Forgeworld. The contradictions also arise when some type of model is in the process of being moved to another base. Here are some current examples:



  • Plastic Seekers of Slaanesh box is supplied with biker bases, but the limited edition re-release of old metal miniatures was sold on 60x35 mm ones. At the same time the plastic miniature can be seen on the 75x42 mm base on the Sector Imperialis 60mm Round, 75mm Oval & 90mm Oval Bases page on GW website.
  • The same goes for Carnifex — old version is still sold on 65 mm round base, while it was supplied with a 105x70 mm oval base in Deathstorm set and Old One Eye's Carnifex Brood bundle
  • New plastic Greater Deamons from Games Workshop use different bases from the re-released Forgeworld versions — both options are included in the list above

Some models are ocassionally shown with unusual bases. In addition to the Hierodule and Forgeworld Warboss on warbike shown above, there are other examples:


  • Some of FW field artillery pieces like Krieg Quad Launcher were initially shown on a large round base that predated the introduction of the 80/100/130/160 mm bases. This was likely just for show.
  • Many Titans, especially Eldar ones, are commonly shown on some kind of custom base, mostly for stability purposes.
  • The same goes for many super-heavy flyers: standard flyer bases can't really support the weight of those monstrosities and modelers are left to create their own basing solutions. The list includes Marauder Bomber/Marauder Destroyer, Kharybdis Assault Claw, Thunderhawk gunship, Sokar pattern Stormbird, Tau Manta, Orca Dropship (OOP) and Tyranid Harridan.


In the light of the above, the desire of some people to enforce very strict basing standards for 40k models seems even more ridiculous. In many cases in is left to the miniature owner to decide what base he wants to use. I, for one, put my Ork Nobs on 32mm bases and my Warboss in mega-armour is on 50mm one which seems perfectly fitting, given the Ork attitudes towards size and power. At the same time, I think that Assassins and Electro-Priests belong on smaller 25 mm bases, but at your workbench only your opinion matters - it's your models, after all. Hope this guile helps - I will add to it as new models get released or repackaged. And good hobbying to you all!

  3. Hi, 2 minor corrections: Kataphron Battle Servitors are on 60mm bases, and Carnifex has a new base: 105x70mm

    I was doing the same work, thanks for rescuing me! It's unbelievable that no one else has made a detailed list like yours.

  5. Broodlord is stated to be on a 75X42 base on the preorder entry.

    Replies
    1. Supposedly it's the same as a 75x46 one. The dimensions aren't as precise as they could be, given that GW bases widen towards the foundation. It' the same with other bases really - if you measure your standard 60mm base you'll find out it's not really 60mm in diameter, but that's how it's called.

  7. Was just trying to figure out the use for the 90mm bases included in Sector Imperialis, and now I know the answer is: Almost nothing. Leave it to GeeDubs to insert so many useless bases

  9. Hi! Really useful reference! I'd like to point out there is an error in the XV8 Crisis Suit entry. Old Crisis uses 40mm, and new Crisis kits use 50mm. Not 50/60.

    ReplyDelete
    Replies
    1. Sure, new plastic ones are on 50mm, but resin XV81, XV84 and XV89 from Forgeworld are sold with 60mm, thus the inconsistency. I don't consider different base sizes between different iterations of a model to be a problem really, that happens all the time.

      Delete
  10. I have to ask. What do you think about 60mm bases that are actually 65mm? I got my Start Collecting Tyranid Hive Tyrant on the one like this and it got me a bit confused

    ReplyDelete

    1. 60mm bases have alway been 65mm in reality
      The only real 60mm base is the clear flying large base

    Broodlord has never been on a 50mm, you're likely thinking of The Patriarch. The Patriarch is a HQ unit for Genestealer Cult and has slightly different stats and psychic powers.

    This is a great source of information.

  17. I love what you're doing here! I just want to mention that the Custodes super Heavy flyer; the Orion Assault Dropship, is on a 160 mm base when in hover mode. It will likely be the same for the upcoming Ares Gunship :)

    ReplyDelete
  18. This is incredibly useful, thank you. One thing that might be worth adding, for people that do clay base decoration, is that the top of the bases are, I believe uniformly, 3mm smaller than the bottom, so that's the size to cut to glue onto the base.

    ReplyDelete
  19. Hi, awesome work!

  20. I believe that there is a new size of round bases being rolled out by GW, 28mm. From what I have read the new Aspect Warriors, both Howling Banshees and Incubi, from the new Blood of the Phoenix box, comes with 28mm bases.

    Is there anyone who got the box and can confirm?

    I also heard about someone who clamed that he got his Tau models from a Kill Team box on 28mm bases, but have no idea if there is any truth to that.

    ReplyDelete
    Replies
    1. Well, is says as much in the assembly guide you can see in any unboxing video. That's enough confirmation for me.

      I have the new Kill Team starter set right here and T'au warriors come with 25s, so that one's a false alarm.

      Delete
    2. Thank you for keeping this guide updated! It really is so incredible helpful!

      While it probably does not really need to be included in a 40k guide, it could be of note that those 28mm bases seem to be used quite a lot in the warbands of GWs Warcry boxed game. So for any of you out there who are thinking about doing some conversions using those models, remember to grab some extra bases if you want to keep your army on a uniform basing size.

      Delete
  21. This is extremely useful, I refer people with base size questions here all the time. That being said the new Tiger Shark model comes with the 160mm round base.

    ReplyDelete
  22. Couldn't find Eldrad Ulthran on the list. After a quick customer service message, he needs a 32mm.

    ReplyDelete
  23. Also Scourges are apparently upgraded to the 32mm slotted bases now, or at least what comes in the box. Don't have an official word from GW, but that's what they're shipping with.

    ReplyDelete
  24. Dose anyone know where I can buy bulk round bases from? I'm looking at buying 700-800 units in either 90 or 100 mm.

  26. This List has the Yncarne on a 65mm base, but ive seen it elsewhere on an 80mm. Can anyone confirm? I just cut and dremeled an 80 and it would be a shame if it wasnt

  27. Tyranid Hierodules aren't on 120x92mm ovals like is listed here. They actually come with a sculpted circular base, approximately 5" in diameter.

    I say approximately because they are a bit misshapen, so aren't perfectly circular.

    1. Interesting case, thanks for the info.

  28. If you wanted to put a Triarch Stalker on a base it would need a 160mm base. I believe it doesn't fit in the box so GW went without base

    ReplyDelete
  29. Hey guys custom building some squiggoths and a gargantuan squiggoth, any idea what base sizes would be reasonable to work toward

  30. I have an email from Forgeworld (which I am happy to send you a copy of if you like) saying that the Harridan should be on a 120x92mm base.

    Replies
    1. Interesting. Emails and social media comments from Games Workshop and Forgeworld are infamously unreliable, but it's good to keep this in mind nonetheless. In the end it doesn't matter all that much, so they likely went with the most widely available option.

  31. Is it acceptable to use a 95mm oval for warboss on warbike, or do I need to cobble together a unique pill base from 2 pill biker bases and a 40mm round base?

    1. I can see no way even the most pedantic event organiser would ever expect you to do something like that

  32. Commander Farsight is missing from this listing. Or is he bundled together with the XV8 Crisis Suits? I believe they used to share the same official base size, but crisis suits were changed to 50mm when they got their plastic models, and farsight maintains his older 40mm base. (At least that is the size that some tournament organizers are requiring, not too terribly reliable I know.)


    Love this list though! Exceedingly useful and I plan to reference it more in the future!

    1. Wahapedia has Farsight listed as a 40mm base also.

  33. This has been such a godsend! I'm surprise printing an Exocrine proxy for a friend and this has been so helpful sizing both the base and the model

  34. Hello,
    Lokhust heavy destroyers are indicated with 60mm bases on GW website, but with 65mm base in your article (pretty useful, I used it many times until today)

    1. The bases GW interchangeably labels as "60 mm" or "65 mm" are in fact 65 millimetres (2.56 inches) in diameter. Check out for yourself!

    2. Oh thanks for the precision... Bad for me I am trying to 3D print my army and buy bases appart... and I am checking on the scale of each model with the images from GW website. If the bases are 65mm and not 60mm as indicated I might have a few models out of scale...

    3. It wouldn't be that big a difference really. Still good to keep in mind though.

  35. Fantastic list and its so nice to see you are keeping up with it! question more than anything else what are your thoughts on having a custodes shield captain on a 50mm base? 40mm is a decent size but just to make them stand out, Thanks!

    1. Thank you! Personally I'd say go for it: most modern releases have HQs one base size bigger than their troops anyway. Given that we have a Hospitaller on 50 and Helbrecht on 65, Custodes characters wouldn't look out of place on 50s at all. Your local tournament organiser may be a stickler about these things though, but that is another story.

    2. Amazing thanks for the reply! Yeah i think it just makes sense to make them stand out more custodes shield captains have very subtle differences compared to the normal guys half the time aha. Thanks again!

  36. Can I ask what you think would be a good base size for each of the following vehicles?

    - Rhino
    - Sicarian
    - Malcador/Dracosan
    - Land Raider
    - Baneblade

    Would be really helpful :)

    1. My religion prohibits placing vehicles that size on bases, so you'd have to look elsewhere 😱

  37. The new Cadian Command Squad mini's are now on 28mm round bases. Great list by the way, very helpful.

    1. Sure, thanks for the input. Human infantry is quite often put on 28 mm these days.

  38. So this is kinda weird but maybe worth including on this list (which is amazing and incredibly useful btw!!)... the Death Korps of Krieg heavy weapon teams that come from Forgeworld are still shipped with 60mm bases. Even though there's only 1 datasheet for the HWT now, because they're still shipped with 60mm bases I'm gonna take that as GW still allowing that base size to be used for the Krieg HWT ;)

    1. Interesting catch there. Forgeworld versions of GW plastics quite often end up stuck to a differently sized base

  39. Great resource, thanks. One small update I noticed. After they were repackaged for 9th, Eldar Dire Avengers are now on a 28mm base.

    1. Thanks! Makes sense as most Aeldari models have been switching to 28mm for a while now

  40. Aren't most first born dreadnoughts (such as Death Company) on 60mm?

    1. GW calls the base by different names at different times, but it has always been 65 millimeters in diameter. Measure it and see for yourself!

  41. Correction: Exalted sorcerer on disk of tzeentch is a 40mm base, not 65, according to the gw exalted sorcerer box store page. Also, are you sure the 65mm is right? I think gw calls it 60mm but I've heard that their measurements are wrong, is that why you have 65mm in your list instead?

    1. Fixed it, thanks. The bases GW dubs as '60 mm' have always been 65 mm in diameter, thus the confusion. I use the actual base sizes in this compilation.
