For the short answer, Duplo studs are indeed taller than twice the height of a Lego stud. And don't rely too heavily on measurements you get from ldraw (and not just for Duplo).
For a really long-winded history on this...
First, note that when I authored the original Duplo parts I never actually measured them with a ruler or calipers, as there was no need....
LEGO Juniors sets use normal LEGO System bricks. In other words, they are exactly the same size as the "normal" LEGO bricks.
However, the Junior sets are specifically designed for younger children. They often have large single-use pieces (for example, for walls or frames), and are generally very easy to construct. They also limit the use of small or ...
I found CAD files for LEGO technic axles here: https://grabcad.com/library/lego-technic-axles-1
and some gears which have holes for technic axles here: https://grabcad.com/library/lego-technic-gears-1
Using their online viewer I found the following dimensions (Which are a little inaccurate due to the limits of their online viewers tools. For more accurate ...
Bricklink lists it as
Technic, Axle 5.5 with stop
The blue number is the length of the axle. It is mentioned in the part list to distinguish axles of different lengths in a set.
In this case, the length is 5.5, so yes, it is written as 5,5 because of the locale.
While there are multiple sizes of instructions and lack of database with dimensions my answer is based on personal observation.
Looking at the stash of my instructions from multiple sets (including several largest Technic models) I can state that the largest dimension I have is of A4 paper size, which is 210 x 297 mm. I'd like to note that this is for ...
Robert Cailliau has summarized how dimensions of LEGO bricks derive from:
The base measure 0.8mm (that's where the 1.6mm already mentioned derives from)
The play measures 0.1mm (for additional space between pieces)
The height of studs 1.8mm
It looks like the number as the same as given in other sources, but there is disagreement about the height of a stud. ...
There is another piece with an odd LDU dimension: the 1x1 bracket is 3 LDU thick. Paired with an Erling brick, which has a 4 LDU offset built in, it's a very compact way to create a 1-LDU offset, like psiaki has done here:
Then it's just a matter of translating the offset into a gap between bricks using standard bracket pieces like I have done here:
One Single Stud Lego brick is 9.6mm H by 8mm W (technically 7.8mm). So at the scale you are looking for we're searching for single stud bricks that are 28.8mm H by 24mm W.
After an extensive search among multiple Lego-style building block manufacturers, I can't find any that use the dimensions we're looking for. Here is a list of companies I searched:
About 3g (2.98g)
Based on a small sample of Minifigure part data provided by Bricklink, a minifigure in it's most basic form (Head, Torso Assembly and Legs Assembley) weighs about 3g.
A small hairpiece or cap will add about 0.3g - 0.4g
Large hairpieces/headgear can add about 0.9g - 1.0g.
Just measured them myself. Some of the dimensions might be just a little bit off, but I hope this suffices:
Length: 111 mm
Width: ~71.7 mm
Height: 40 mm (extra 8 mm if you have a rechargeable battery installed)
Length: ~105 mm
Width: 40 mm
Height: ~45 mm
Length: 44 mm
Width: 44 mm
Height: 30 mm
You can derive detailed part geometry using the LDraw parts library. LDraw provides freely accessibly models for nearly every part that Lego has produced. I'd recommend parsing these parts rather than rolling you own models if you're going to be using many parts.
Here is the relevant content of the file representing a 1 x 1 round plate:

I assume you mean L when you say units?
Well anyhow, unless im misunderstanding, I would try these: https://www.bricklink.com/v2/catalog/catalogitem.page?P=6575
You can stack 3 of them up to get 1 and a half L
If you mean 3L long instead of wide however this should still work because it has an axle hole which is 1.5 apart, it also has axle holes that are ...
If you mean specifically Lego bricks, I'm pretty sure the 1x16 was/is the longest one made. Outside of the 1x? sized bricks, the longest plain shaped brick that I know of is part #30072 or #47122 at 24 studs long. I don't know about other brands though.
Interesting related post:
What is the largest single LEGO piece?
I have a micrometer for measuring with 0.1 mm precision. Using that I measured following lengths:
diameter of top cylinder (stud): 4.9 mm
diameter of lower cylinder: 6.4 mm
diameter of middle ring: 7.9 mm
height of middle ring: 1.0 mm
total height of the plate: 5.1 mm
inside diameter of lower cylinder: 4.9 mm (no surprise)
Can anyone confirm or question ...
Bricklink has this information for most sets. If you search for the set number, you get several entries. The top one is the entire set, and has the weight for the full sealed box with parts and instructions. Then there are two more entries, one for the Instructions and one for the Box. See here for an example using set 41314 Stephanie’s House.
If you go ...
The math you're suggesting may work for going straight forward or backward where slipping is limited. For a turn, it will not come close. Even getting the center of rotation of the turning robot will be difficult. The tracks will have to slip. A tracked robot can not turn without those tracks slipping. Differences in friction will alter the turn. More ...
I don't know where you got that image, but you could always try and print the brick using the dimensions shown.
Using the brick (#32316) shown in your example it might be possible to produce a 3D model using the 32316.dat file that's available in the LDraw library. The next problem would be placing the brick in a model and exporting it as a file type that ...
This is not a full answer, but the Free Art and Technology Lab seems to have carefully measured a DUPLO brick as part of the Free Universal Construction Kit. The parts are made available as STL file, for instance
http://www.thingiverse.com/thing:15945 - includes DUPLO upper side
http://www.thingiverse.com/thing:15924 - includes DUPLO bottom side
So the box says 49 inches long, the official description says "under 50 inches long".
I just measured the width (about 13.25 inches) and height (about 9.5 inches) on my assembled set.
So a rough minimum inner size box would be 50"L x 13.5"W x 10"H.
I've always thought those flat, round 1x1 pieces were the smallest sphere-esque shape. Most of the other pieces here are longer in at least one dimension than these guys.
This is probably the smallest LEGO brick that is compatible with a stud/tube connection.
There's a version with a hole in the stud that is 'smaller' in that it weighs less, although the ...
Since no answers were given for two days, I'll convert my comment to a full answer:
If you haven't found anything yet but have access to a photocopier, you could try making a copy of the back side that contains the eyelets. The resulting print will be a 1:1 paper version of the back side, which you can tape on the wall intended for hanging the cases and ...
The largest LEGO ship that officially floats in water is the Cargo Ship that comes in 7994-1 LEGO City Harbor:
It is the only set which contains the 74 x 18 x 7 Boat Hull, which is the largest boat hull LEGO has made.
