What is the largest single LEGO piece ever produced? This does not include LEGO affiliates like Duplo.


  • It must be a purchasable block.

  • By largest, I mean largest by Volume/Weight of Plastic

Does this include special one-off bricks? I have seen some giant things that could be considered "one brick" in the Lego Store at the Mall of America, for example, but they're not things you could ever buy. – user23 Oct 25 '11 at 20:50
Must be a baseplate. Waiting for the ?x? count to come in... – Lunatik Oct 25 '11 at 20:50
Do you mean by area or volume? – Zhaph - Ben Duguid Oct 25 '11 at 20:51
Note that DUPLO isn't really an affiliate of LEGO, DUPLO is LEGO. – BoltClock Oct 25 '11 at 20:53
By "no affiliate", I think he wanted to exclude things such as playtables or other furniture pieces, which would easily win. – Joubarc Oct 26 '11 at 7:46

The "Extra Large" grey baseplate is 15"/38cm square, with 48 studs to a side.

Alternatively, the moulded castle baseplate had a greater volume (with hight), and a base size of 32x48 studs and 6 bricks high (15"x10"/38x25cm) (in other colours as well):

Baseplate 32 x 48 x 6 Raised with Corner Pits and River Pattern (30271px1)

Tim offered up the following, also with a base size of 32x48 studs, 6 bricks high (15"x10"/38x25cm) (it came in a few other colours too):

Baseplate 32 x 48 x 6 Raised with Steps and MdBlue/Green Garden Pattern (44510px2)

Peeron also lists a 48x48 Raised with Staircases and Pits:

Baseplate 48 x 48 Raised with Staircases and Pits with Yellow Cobblestone and Ivy Pattern (33214px2)

As well as a very old "Giant Base Plate" and a "Road 3-way Curve with Gray Pattern", both at 50x50 studs.

Joubarc suggested the "Boat Hull Floating 74 x 18 x 7":

Boat Hull Floating 74 x 18 x 7 (57789)

Stretching the definition of "Single Piece" somewhat, the "Electric Technic Control Centre with Yellow and Red Buttons" from the Technic Control Center was a beast of a part:

Electric Technic Control Centre with Yellow and Red Buttons (2840c01)

Made this CW to allow others to add their contenders

It's still pressed from a single sheet, so the volume of plastic is probably less. – fredley Oct 25 '11 at 21:03
@fredley Techincally I believe they're injection moulded rather than pressed, and the thickness is usually consistent across the part... – Zhaph - Ben Duguid Oct 26 '11 at 14:16
This is getting silly - I need someone to get all these pieces and weigh them, or measure their volume via displacement ;) – Zhaph - Ben Duguid Oct 26 '11 at 15:35
A LARGE bounty will be awarded to anyone who does that! – fredley Oct 26 '11 at 15:38
@Zhaph it's my understanding that baseplates are vacuum-formed. There is a mold involved but the sheet of plastic goes in whole. – Erik Olson Nov 4 '11 at 6:49

if you're just counting the basal area, it seems to be the gray 48x48 baseplate:

man, this was a beast of a baseplate. Also game in green as half of the lego football field. – tombull89 Oct 25 '11 at 21:07
Before that, the extra-large gray baseplate was 50x50, but nowadays only the 48x48 can be bought. – Joubarc Oct 26 '11 at 7:45
Also in Blue, plus some rare ones that were never in sets: – gev Feb 13 '14 at 3:00

If you go by Volume/Weight. This is heaviest single-element I've ever seen. It's not just plastic but it's one element made and sold by LEGO.

Good call, I didn't think about "multipart" single bricks, although I think I can still trump that one with a different Technic controller hang on... – Zhaph - Ben Duguid Oct 26 '11 at 15:12
I think there's two categories: Single plastic-only piece and Single Lego element. – pcantin Oct 26 '11 at 15:22
There you go, Electric Technic Control Centre with Yellow and Red Buttons ;) – Zhaph - Ben Duguid Oct 26 '11 at 15:29
Wow! That baby is a monster! Thanks – pcantin Oct 26 '11 at 15:31
I found this video ( with the Electric Technic Control Centre in use – pcantin Oct 28 '11 at 10:24

@Zhaph : (from my sister's LEGO collection) lego fairy castle base

share|improve this answer
What set was this from? Possibly a Belville one? – tombull89 Oct 26 '11 at 9:10
@tombull89 Yeah, my sister's: Bellville 5862 – Tim Oct 26 '11 at 10:32
Your sister's, yeah, right :-) – Joubarc Oct 26 '11 at 18:53
@Joubarc And we all know how many 'sisters' you have. – Mateen Ulhaq Nov 19 '11 at 23:56
