Sizes

KSP2 brought more life to the sizes presets in KSP1, giving them labels as well as colors for each diameter. Here is some information about them.

This list does not contain all possible sizes as defined by the game, and it also contains modded part sizes. For a list of all the stock game part sizes available to be used in the Core Part Data module and part JSON definitions files, see Size Category.

Here's how to understand labels and how to find the right parts. I recommend excluding the reentry mesh when searching for a part or include the category of the part you want to find. Sadly you cant filter two things at the same time so you'll have to look through the whole list. One very good tip is to look for a short name that doesn't have _reentry or _lod1, lod2 in it. That's usually the actual part. Also you can sort the categories so they are together for each medium like texture, sprite, text, animation or mesh etc.

Part Size

(x)V	=	Size of part	Label
0v	=	Extra Small	(XS)
1v	=	Small	(SM)
2v	=	Medium	(MD)
3v	=	Large	(LG)
4v	=	Extra Large	(XL)
5v	=	Extra Extra Large	(XXL)

Part Scale

S(x)	=	Scale of part	Reference	Stack
s1	=	One Stack	none	1x1
s2	=	One Stack that contains two of S1	Short	1x2
s3	=	One stack that contains two of S2	none	1x4
s4	=	One stack that contains two of S3	Long	1x8

Stock KSP2 Part Sizes and Modded Sizes

Here are the Charts for the Sizes you'll have to follow when modeling.

Formula behind the design language of parts: Height + (Fake) Margin = Bevel [Amount to Bevel]

Stock Parts

Size	Width	Height	Margin	Bevel	Faces
XS	0.625m	23.4375cm	+ 5cm	[0.025]	24
SM	1.25m	46.875cm	+ 5cm	[0.025]	24
MD	2.5m	0.9375m	+ 0.05m	[0.025]	36
LG	3.75m	1.875m	+ 0.1m	[0.03]	48
XL	5m	1.875m	+ 0.1m	[0.05]	48
XXL	10m	10m Ball			60

So what does Fake Margin mean? Well it's basically the point where the two objects connect and clip into each others geometry making a seal. Those parts don't have collisions. It can also be referred to as wiggle room or a light bleeding seal. The real height is what’s visible and also what is measured.

Example of Fake and Real Height:

Example of Visible Height:

As you can see. The blue line is where the actual object connects to its Gizmo/Origin and the “fake” height/Margin is inside the other object. So when modelling your object, please work in the volume of the parts real/actual size and when you are done you can increase the volume to the (Margin) amount for the respective size.

Modded/Custom Parts

Size	Width	Height	Faces
XS-	0.3125m
XS+	0.9375m
SM+	1.875m
MD+	3.125m
LG+	4.375m

Special Sizes

Other than the ones shown above, there's also some extra sizes added by KSP1 (and ported to KSP2) and by mods. Here's some of them:
