gleichgroßen

Gleichgroßen is the inflected form of the German adjective gleichgroß, meaning “equal-sized” or “the same size.” It is used to describe plural nouns and appears in accusative and dative cases when a determiner is present (for example, after die, dem, mit, den, etc.).

Grammatically, gleichgroß follows standard German adjective declension rules. With definite determiners or other signals of the plural, the attributive form takes the weak ending -en: die gleichgroßen Teile, die gleichgroßen Würfel. In the dative plural after prepositions like mit, den gleichgroßen Teilen; die gleichgroßen Würfel passen in den Karton. Without a determiner, the strong ending for nominative or accusative plural is -e: gleichgroße Teile, gleichgroße Würfel.

Usage and meaning: gleichgroß expresses that two or more objects have identical dimensions such as length, width, or overall size. It is common in everyday language, in mathematics and geometry discussions, and in manufacturing or quality-control contexts where precision about dimensions matters. The term is often applied to objects regardless of their shapes; two objects can be gleichgroß and still be geometrically non-congruent if their shapes differ.

Related terminology: the noun Gleichgröße denotes a quantity or magnitude, and Gleichgrößen is its plural in technical contexts. The adjective form gleichgroß can also be written in compound or hyphenated forms in less formal usage, but the standard written form is typically gleichgroß.
