samankokoisuus

Samankokoisuus is a Finnish term that denotes the property of having the same size. In everyday language it is used to describe objects or figures that share identical overall dimensions according to a chosen size measure. The precise meaning depends on context and may refer to equal length, equal area, equal volume, or equal bounding dimensions.

In mathematics, samankokoisuus is often discussed with respect to a specific size metric. For linear objects, such as line segments or sides of polygons, samankokoisuus means equal length. For two shapes, it can refer to equality of a chosen measure such as perimeter or area. The concept is distinct from samankaltaisuus (similarity), which concerns proportional scaling of dimensions and shape rather than exact equality.

In design, printing, and cartography, maintaining samankokoisuus across elements supports visual consistency and scale. For example, symbols on a map or icons in a user interface may be designed to be samankokoiset to convey equal importance or legibility. In manufacturing or biology, samankokoisuus may describe parts, specimens, or products that have equal physical dimensions.

Etymology and usage notes: samankokoisuus is formed from sama (the same) + koko (size) + -isuus (a noun-forming suffix). The term is common in Finnish mathematics and technical language, though in everyday speech speakers often specify the particular size measure used (length, area, volume, etc.).
