Velikosti

Velikosti (from the Czech word velikost, meaning size or magnitude) denotes the various measurable extents by which objects, quantities, or phenomena are described. The term is used across many domains, where size is defined by specific units, scales, and reference points. Because size is context dependent, it can be expressed qualitatively (small, medium, large) or quantitatively (meters, liters, bytes).

In clothing and footwear, velikosti indicate fit. European sizes are often numeric, while US and UK systems differ. Measurements such as chest or waist circumference, or foot length, determine size. Consumers may encounter conversion tables, with varying accuracy between brands and regions.

In geometry, physics, and biology, size refers to linear dimensions (length, width, height), area, or volume, as well as body size and allometry. In statistics, size can refer to sample size or to the magnitude of a variable, and size distributions describe how common different magnitudes are within a population.

In information technology, data size is measured in bytes, with prefixes such as kilobyte, megabyte, gigabyte, and beyond. File sizes, memory capacity, and bandwidth are all described by size.

Standards bodies such as ISO, IEC, and ASTM establish guidelines for sizing in manufacturing, apparel, packaging, and engineering to improve comparability and consumer understanding.

Overall, velikosti are contextual constructs that require defined measurement units and reference points to be comparable across contexts.
