bladlengde

Bladlengde is a compound word from Scandinavian languages (blad meaning "leaf" or "blade" and lengde meaning "length") used to describe the linear measurement of a blade- or leaf-shaped object. The term is applied in several fields, most commonly botany and material craft, where it denotes the size of an individual leaf or cutting edge and is an important descriptive or regulatory parameter.

In botany, bladlengde refers to the distance from the base of a leaf (where it attaches to the stem) to the tip, typically measured along the midrib. Botanists record bladlengde to characterize species and varieties, to compare growth under different conditions, and to support identification keys. Measurements are usually reported in millimetres or centimetres and may distinguish between straight-line length and length following curvature.

In cutlery, edged tools and weapons, bladlengde denotes the length of a blade from the tip to the point where it meets the handle or hilt. It is used in manufacturing specifications, trade descriptions and legal definitions; the latter can influence possession and transport rules, which vary by jurisdiction.

Other uses include aeronautical and nautical contexts (propeller or rudder blade length) and horticulture (leaf-size descriptions in cultivars). Measurement conventions and significance depend on discipline and local standards. The term highlights the practical role of simple linear dimensions in taxonomy, design, regulation and comparative description.
