Size-Based Patterns

Size is one of the most visually striking attributes of shapes in AR boxes, yet it is often used as a distractor rather than the actual rule. Learning to recognise when size is genuinely part of the pattern — and when it is irrelevant noise — is a crucial AR skill.

How Size Appears in UCAT AR

In the UCAT, shapes typically appear in two or three distinct sizes:

Size category	Description
Small	Noticeably smaller than other shapes in the box
Medium	Between small and large (not always present)
Large	Noticeably larger than other shapes in the box

Size is always relative — there is no absolute measurement. A "large" shape is large compared to the other shapes in the same box or across boxes in the set.

Category 1: Uniform Size Rules

The simplest size-based rule: all shapes in a set are the same size or different sizes.
