Hey Bricklink,

I would love to add dimensions to my parts that don't have them, but unfortunately
they don't sell rulers that measure by studs and bricks at the hardware store.
Also, I didn't take the brick-ometry class in high school. Can you please
change the dimensions of parts to an international standard? Metric, Imperial,
I don't care, as long as more than just the users of this site know what
they mean and I can buy a ruler at the dollar store that measures them.

It would be a great help for shipping, especially when parts over a certain dimension
can't be shipped via a certain package size. I know, I can't believe
Canada Post doesn't convert bricks to centimetres, what snobs.

I hate to say this but brick owl is good for one thing, they list their measurements
in cm. Guess where I go most of the time for part dimensions? I won't spoil
it.

So in conclusion, please, please, please change the way parts are measured in
Bricklink from studs and bricks to centimetres, millimetres, or even inches (counting
by twelves - shudder).

Thanks for your consideration!

Wait a second… You can display packaging dimensions in bricks and studs?!

Seriously, though. All of my packaging dimensions are displayed in millimeters
and weight is displayed in grams. I don't know what happened on your end
that made them show up in bricks and studs or if there is even a setting for
that. Perhaps it's a Canadian thing?

Or are you referring to the names of the parts? That is unlikely to change any
time soon as it is much easier to refer to parts by their dimensions in bricks
and studs than my their dimensions in inches or millimeters, however convenient
that may be for packing and shipping purposes.

Good suggestion. Measuring dimensions in bricks and studs makes sense for basic
parts such as bricks and plates, but not for small parts such as minifigure accessories
and non-system elements such as technic.

However, it's just a simple matter of unit conversion. I always remember
that one stud equals 5/16 of an inch and a plate is 1/8 of an inch. For the rest
of the world, that's approximately 7.9 and 3.2 mm.

You make my point exactly. First, we already have universal systems of measurement,
why convert to a system of measurement that only exists on this site? Second,
converting creates a barrier for people like me who just want to update a part
size, not learn a new language. Lastly, I'm a perfectionist and this "approximately"
business is for the birds. That's why hardware stores sell rulers, so we
can know exactly how long something is.

When it comes to brick names, I prefer 2x2 brick to cuboid 16.0 mm x 16.0 mm
x 9.6 mm, and that is before you start adding terms for modifications. And based
on that, one measuring system makes sense, so not mixing studs with inches and
mm. Where necessary other units can be used when clarification is needed, for
example capes and strings, elastics, wheels. For torsos, hair, minifig accessories
and so on, I don't think dimensions are needed, just shipping dimensions.

Let's hope so! Although I think you are reading a lot between-the-lines in
those two posts as my specific request is not mentioned. Hopefully if it's
not on the to do list it might be in the future (if enough people vote this suggestion
up).

You can stop spinning.
First you have to understand that you are mixing up two sets of dimensions.
There are stud dimensions, which are shown on the catalog page, and that won't
change, shipping also has nothing to do with that (although I think somewhere
along they were used to set initial shipping dimensions).

The dimensions you want to see in a 'normal' manner are the actual shipping
dimensions that are used to calculate shipping options. And they are already
in 'normal' standards, namely, as Wildchicken pointed out, in mm and
grams.
You can change those dimensions in your own inventory, that way they count only
for you. You could also make a post in the Packaging Dimension topic to let an
admin set the dimensions for the whole of Bricklink.

You can't however set them through the change item form (yet?).

This is exactly what I'm asking for. I'm aware that I can change them
for my own store, but I'm thinking of the greater good. I want to change
them for everyone using the change item tool, but it's too much hassle right
now because it's not in metric or imperial.

I don't know if that tool actually submits a request to change an item's
packing dimensions - I think it is just to change the dimensions in studs/brick
height

The change item page sets the dimensions of the part in studs. People use studs
for measurements when building, not mm or inches. If I've got a 2x16 plate
and I put a 2x2 tile on one end, a 2x2 tile on the other and I want to work out
which part(s) I need to tile the rest, I can quickly determine that I need 2x12
worth of tiles. I don't want to have to get a ruler out to measure the gap
in mm, then work out what parts have the correct size to fit. I can look at the
part, and the studs act as a measuring device.

Whereas the shipping sizes are in mm, as the volume of packages in more common
units are necessary.

It's a moot point now, since this is actually being implemented, but my point
is that when adding part sizes, doing that by stud and brick height is not easy
in most cases or practical compared to standard measurements. ie. sticking a
ruler next to a part and measuring it's height. The conversion to studs and
brick heights should be on the server side, not the human input side.

It is just as easy to stick a brick next to a part and count the studs as it
is to put a ruler next to a part and measure it.

Given that only one measurement of size should be used where possible for a particular
function, and how easy it is to determine the size of the majority of bricks,
plates, and other parts by just looking at them, then the studs as the visual
dimensions should (and will be) retained. The system scale and packing scale
are two different things. Of course, there are other scales in use too. DUPLO
is also measured in studs but this time DUPLO studs. So a DUPLO 2x2 brick is
still 2x2x1 in studs, the same as a system 2x2 brick. The difference is that
the user is expected to know that DUPLO studs are different to system studs.

  It's a moot point now, since this is actually being implemented, but my point
is that when adding part sizes, doing that by stud and brick height is not easy
in most cases or practical compared to standard measurements. ie. sticking a
ruler next to a part and measuring it's height. The conversion to studs and
brick heights should be on the server side, not the human input side.

It is just as easy to stick a brick next to a part and count the studs as it
is to put a ruler next to a part and measure it.

Given that only one measurement of size should be used where possible for a particular
function, and how easy it is to determine the size of the majority of bricks,
plates, and other parts by just looking at them, then the studs as the visual
dimensions should (and will be) retained. The system scale and packing scale
are two different things. Of course, there are other scales in use too. DUPLO
is also measured in studs but this time DUPLO studs. So a DUPLO 2x2 brick is
still 2x2x1 in studs, the same as a system 2x2 brick. The difference is that
the user is expected to know that DUPLO studs are different to system studs.

Yes, I agree, placing a piece across studs is pretty easy, although not very
accurate. It is better to start off accurate and then round up or down to stud
length on the server side. However, brick height is not that easy, even on the
human side. Now you're getting into very inaccurate measurements and guesstimating
when dealing with partial brick height. Height is especially easier with standard
measurements.

when dealing with partial brick height. Height is especially easier with standard

I find measuring parts in brick height quite easy, use a pile of bricks with
three plates on the top. Measurements are then accurate to 1/3 a brick height
which is good enough for most parts as that is the accuracy that they are quoted
to.

For non-brick parts two measurements are sometimes quoted as needed, but the
cm dimensions don't go into the dimensions field but into the name. For example:

 
Part No: 522  Name: Minifigure Cape Cloth, Standard - Traditional Starched Fabric - 4.0cm Height
* 
522 Minifigure Cape Cloth, Standard - Traditional Starched Fabric - 4.0cm Height
Parts: Minifigure, Body Wear
 
Part No: 522c  Name: Minifigure Cape Cloth, Standard - Traditional Starched Fabric - 3.9cm Height
* 
522c Minifigure Cape Cloth, Standard - Traditional Starched Fabric - 3.9cm Height
Parts: Minifigure, Body Wear

Telling these two apart if you only have one of them is difficult, even with
a ruler.

 
Part No: x77ac75  Name: String, Cord Thin    75cm
* 
x77ac75 String, Cord Thin 75cm
Parts: String & Net
 
Part No: 5102c38  Name: Hose, Pneumatic 4mm D.  38L / 30.4cm
* 
5102c38 Hose, Pneumatic 4mm D. 38L / 30.4cm
Parts: Hose, Pneumatic 4mm D.

It makes sense to have them in the name here because the size is often very different
to the packaging dimensions, and also sometimes you need to know a length in
studs or in cm depending on what you are doing with it.

I'm sure that anything I say will not convince you otherwise. So let's
leave
it at that.

Not at all, for packaging they make sense. But for describing part sizes then
studs are better.

Yes! Ha,ha. I just grabbed the graphics from a project I already had open. The
first chart I made was for reals, this one was just for fun.

Gonna go for a third as soon as another either/or problem pops up...

  Hey Bricklink,

I would love to add dimensions to my parts that don't have them, but unfortunately
they don't sell rulers that measure by studs and bricks at the hardware store.
Also, I didn't take the brick-ometry class in high school. Can you please
change the dimensions of parts to an international standard? Metric, Imperial,
I don't care, as long as more than just the users of this site know what
they mean and I can buy a ruler at the dollar store that measures them.

It would be a great help for shipping, especially when parts over a certain dimension
can't be shipped via a certain package size. I know, I can't believe
Canada Post doesn't convert bricks to centimetres, what snobs.

I hate to say this but brick owl is good for one thing, they list their measurements
in cm. Guess where I go most of the time for part dimensions? I won't spoil
it.

So in conclusion, please, please, please change the way parts are measured in
Bricklink from studs and bricks to centimetres, millimetres, or even inches (counting
by twelves - shudder).

Thanks for your consideration!

As some have already mentioned, we are presently working to improve the way the
site handles dimensions. The first step in the project will allow users to submit
packaging dimensions (which henceforth will be called "packing dimensions") through
the normal catalog upload forms.

These dimensions will be displayed on the catalog detail page. For parts, we
will leave the stud dimensions where they are and the packing dimensions will
be shown underneath, in centimeters (or inches, if that is how you have your
preferences set up).

On the catalog upload forms, the dimensions will be entered in centimeters. Users
will accumulate catalog credits for uploading packing dimensions data.

This project is currently underway.

Sounds great! Will the catalog admins then be in charge of this data? Can we

The catalog admins will indeed be in charge of this data. It is up to them what
they will accept.

Fantastic, thanks!

I might add that since Jan. 1, 2020 communication on Bricklink has vastly improved
in the forum. Thanks again!

  As some have already mentioned, we are presently working to improve the way the
site handles dimensions. The first step in the project will allow users to submit
packaging dimensions (which henceforth will be called "packing dimensions") through
the normal catalog upload forms.

These dimensions will be displayed on the catalog detail page. For parts, we
will leave the stud dimensions where they are and the packing dimensions will
be shown underneath, in centimeters (or inches, if that is how you have your
preferences set up).

On the catalog upload forms, the dimensions will be entered in centimeters. Users
will accumulate catalog credits for uploading packing dimensions data.

This project is currently underway.

So we are moving from the current millimeters to centimeters? Does that
mean all current measurements will be restated simply by a factor of 10? Are
there controls in place to ensure:
1. that this conversion is handled properly?;
2. that both inventory views are updated at the same time to ensure that custom
and catalogue dimensions for all items in seller inventories are correctly converted
to centimeter?;
3. that both inventory views display correctly in future?
4. That seller shipping methods and restrictions are updated automatically?
5. That you stress test catalogue items in carts first to make sure that the
correct answers are given for such carts?
6. That all current carts and open orders are not impacted with a change which
would make it impossible to continue with the order or having to redo the cart
entirely?

If the above cannot be done, it might be better to keep the standard as millimeters

I think you should also have the catalogue admins set the standards of how the
measurements should be taken prior to giving them the responsibility of approving
member requests for changes and ensure that the community is made aware of these
standards. It serves no purpose to make it easier to make submissions and then
3 years from now, we need a catalogue project again to fix everything back to
some defined standard.

Some standards:
The level of precision (should be 2 decimals in mm and 3 if you really are going
to cm)
How foldable and parts such as strings are measured;
How parts with two possible packing methods supplied by TLG are measured (eg
string loose and string wound around the cardboard insert);
How minifigures are measured;
How items in cardboard sleeves are measured when included with minifigures or
other parts;
How boxes are measured;
Standardise the measurement of decorated parts;
Automatically add measurements for new decorated parts form the standard measurement;
Automatically apply dimensions when variants are split;
When an item is defaulted to weight and when it is defaulted to volume;
Define the standard for weight and volume default if these default settings are
to be fixed by users at the time of submission;
How to determine the x y and z sides so that dimensions are displayed correctly
(I know it does not make any difference to actual volume calculations, but it
looks a bit neater if all parts are 8 x 8 x 16 and not some at 8 x 16 x 8 or
16 x 8 x 8)
Etc.

  As some have already mentioned, we are presently working to improve the way the
site handles dimensions. The first step in the project will allow users to submit
packaging dimensions (which henceforth will be called "packing dimensions") through
the normal catalog upload forms.

These dimensions will be displayed on the catalog detail page. For parts, we
will leave the stud dimensions where they are and the packing dimensions will
be shown underneath, in centimeters (or inches, if that is how you have your
preferences set up).

On the catalog upload forms, the dimensions will be entered in centimeters. Users
will accumulate catalog credits for uploading packing dimensions data.

This project is currently underway.

So we are moving from the current millimeters to centimeters? Does that
mean all current measurements will be restated simply by a factor of 10? Are
there controls in place to ensure:
1. that this conversion is handled properly?;
2. that both inventory views are updated at the same time to ensure that custom
and catalogue dimensions for all items in seller inventories are correctly converted
to centimeter?;
3. that both inventory views display correctly in future?
4. That seller shipping methods and restrictions are updated automatically?
5. That you stress test catalogue items in carts first to make sure that the
correct answers are given for such carts?
6. That all current carts and open orders are not impacted with a change which
would make it impossible to continue with the order or having to redo the cart
entirely?

If the above cannot be done, it might be better to keep the standard as millimeters

I think you should also have the catalogue admins set the standards of how the
measurements should be taken prior to giving them the responsibility of approving
member requests for changes and ensure that the community is made aware of these
standards. It serves no purpose to make it easier to make submissions and then
3 years from now, we need a catalogue project again to fix everything back to
some defined standard.

Some standards:
The level of precision (should be 2 decimals in mm and 3 if you really are going
to cm)
How foldable and parts such as strings are measured;
How parts with two possible packing methods supplied by TLG are measured (eg
string loose and string wound around the cardboard insert);
How minifigures are measured;
How items in cardboard sleeves are measured when included with minifigures or
other parts;
How boxes are measured;
Standardise the measurement of decorated parts;
Automatically add measurements for new decorated parts form the standard measurement;
Automatically apply dimensions when variants are split;
When an item is defaulted to weight and when it is defaulted to volume;
Define the standard for weight and volume default if these default settings are
to be fixed by users at the time of submission;
How to determine the x y and z sides so that dimensions are displayed correctly
(I know it does not make any difference to actual volume calculations, but it
looks a bit neater if all parts are 8 x 8 x 16 and not some at 8 x 16 x 8 or
16 x 8 x 8)
Etc.

This is an excellent list and very well thought out. I hope the powers that be
are listening!

I think that might put people off contributing. Given parts are rarely packed
touching without wasting space, then one decimal place for mm is fine, even the
nearest mm would be fine.

Yes. For now, the stored values will be in mm, but entering and display will
be in cm. This enables us to release the feature without having to touch the
instant checkout logic.

Ultimately, though, we will want to move everything to cm, and the seller's
inventory page will be changed to reflect that in time.

1. that this conversion is handled properly?;

All the standards were fully considered before the project was started. However,
we may elect to change / adapt if we find some things that do not fit within
the planned guidelines.

We likely will not apply any automatic calculations, as this is done nowhere
else on BrickLink.

  Some standards:
The level of precision (should be 2 decimals in mm and 3 if you really are going
to cm)
How foldable and parts such as strings are measured;
How parts with two possible packing methods supplied by TLG are measured (eg

Automatically add measurements for new decorated parts form the standard measurement;
Automatically apply dimensions when variants are split;
When an item is defaulted to weight and when it is defaulted to volume;
Define the standard for weight and volume default if these default settings are
to be fixed by users at the time of submission;
How to determine the x y and z sides so that dimensions are displayed correctly
(I know it does not make any difference to actual volume calculations, but it
looks a bit neater if all parts are 8 x 8 x 16 and not some at 8 x 16 x 8 or
