Quick Navigation: Numbers A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Miscellaneous


This page defines all categories in the BrickLink reference catalog. Categories are sorted in alphabetical order and definitions take up no more than a single line on the page. To request changes to category definitions, post a catalog request in the discussion forum.

Items are categorized by placing them into the categories where they most naturally fit, usually meaning where they are deemed most likely to be found. Similar items should be grouped together in the same category whenever possible.

The following categorization criteria should be used for items in the Parts item type in descending order:

  1. Building System/Theme - If the part is specific to one building system and is primarily or only compatible with other parts from that system (Bionicle, Duplo, Galidor, Modulex, Znap, etc.), the part is placed into the appropriate themed category. If the part is used in multiple systems this criteria may be skipped.

  2. Composition - If the material of the part is cloth, foam, paper, a thin sheet of plastic, or is in some other way a non-standard part, the part is placed into the appropriate category. This includes parts with electronics or magnetic features.

  3. Use/Function - If the part is primarily used as figure headgear, a wheel, a sheet of stickers, a hinge, a fence, to display an effect of energy, to launch a projectile, or some other defined use or function, the part is placed into the appropriate category.

  4. Shape - If the part is shaped like a cone, a slope, a wedge, a brick, or some other defined shape, the part is placed into the appropriate category.

  5. Other Criteria - If the part has not been categorized using the above criteria and does not fit into another existing category (Special Assembly, for example), then it may be necessary to modify the definition of an existing category or create a new category.

Hierarchal categorization systems for LEGO items are imperfect and inconsistencies are the result. The goal of this page and the guidelines it contains are to reduce inconsistencies, not completely eliminate them.
