An aln is an old Scandinavian unit of length traditionally used in Norway, Sweden, and Denmark, mainly for measuring cloth and textiles. It is roughly equivalent to 59.4 centimeters (about 23.4 inches), though the exact length varied by region and time period.


The aln was based on the length of the forearm, similar to the cubit in other cultures, and was commonly used by tailors and merchants.


Though obsolete today, the aln reflects historical measurement practices tied to the human body and remains of interest in historical and cultural studies of Scandinavia.
