Proposed improvements in this update

I am constantly trying to improve the short text descriptions for each part. With this update, I’m exploring the consistent use of diameter (Ø) indicators on many round parts. This is especially relevant when you have a large part with a rounded corner – knowing the diameter/radius of the corner will help you determine which parts to use above or below it. As you can see from the example image, this should also improve parts which already show a diameter (such as tires and wheels).

Using "Ø" symbol to indicate diameter of rounded parts.

Using “Ø” symbol to indicate diameter of rounded parts.


  • 1×2 Tile, Ø1 Rounded Ends (part 1126)
    When Ø is followed by a number without units, it means studs. I could have said “Ø1L” instead of “Ø1”, but I want to optimize for simple cases.
  • Hose, Ribbed Ø7mm (part 78c**)
    When Ø is followed by a measurement in mm, I will clearly say so, as in this example “Ø7mm”.
  • Ø24mm × 11mm Integrated Tire w/ Pin (part 72206)
    I will probably update wheels to use this format as well, as in this example.

This is similar to how I started indicating the angle (°) for slopes in version 3.2… I do worry that awareness of ‘Ø’ as the symbol for Diameter is low. While it is certainly something people can learn, I do not want to introduce too much confusion.

This is a potentially major change, so FEEDBACK IS WELCOME! (You can email me or leave a comment.)

P.S. This change was inspired by some official LEGO part names which also use the “Ø” symbol. That symbol happens to be a letter in Danish, but it is also used in mathematical circles (pun intended) to mean diameter.

    I like the short symbol for the diameter. But please make sure to use the symbol ⌀ (Unicode U+2300 diameter sign), and not Ø (U+00D8 latin capital letter o with stroke).

      I tried to use the correct unicode character for Diameter, but unfortunately it is a blank character in Arial font.

      In a modern app like Word, a character that doesn’t exist in the selected font (ex: Arial) will automatically wrap to a font face that does contain the character (ex: Segoe UI Symbol).

      Brother P-Touch Editor does not work correctly, so I need to use the ‘incorrect’ character to make this work, unfortunately.

    I like the change to the symbol for diameter. The less space used whilst showing useful info the better.

    I’m not sure you will get much negative feedback about it in the comment section. If somebody is only learning about the symbol from this article then they are going to be able to understand the labels from now on. It’s the people who don’t know the symbol and don’t read this post that will have issues.

    About the symbol for diameter, I think it’s a good idea as long as you have a legend somewhere that explains the symbol.
