Linijka

Linijka is a straight-edged measuring instrument used to measure length and to draw straight lines. In Polish, the term most commonly refers to a rigid strip, usually made of plastic or metal, with metric graduations in centimeters and millimeters; many models also bear a dual scale with inches on the reverse. Typical lengths are 15 cm, 20 cm, and 30 cm. A folding ruler (linijka składana) exists as a variant, consisting of linked segments that can extend to longer ranges.

Description and variants: Standard linijki are flat and straight, with a precise edge for alignment. Steel linijki are favored in drafting and workshop settings for durability and accuracy, while plastic and wooden versions are common in schools and light tasks. Some models include non-slip backing, a raised guiding edge, or a magnified or laser-engraved scale.

Usage: Linijki are widely used in education, drafting, carpentry, and crafts to transfer measurements, verify dimensions, or draw straight lines. They function best for short-range measurements and quick checks. In professional contexts, precision, material stability, and the quality of the markings influence accuracy.

Etymology and context: The word linijka derives from linia, meaning line, with a diminutive suffix -jka, indicating a small line or strip. In informatics and publishing, linijka can also denote a software ruler used to set margins or tabs, depending on the program.
