The line as a small English unit of length, variously reckoned as 1/10, 1/12, 1/16, or 1/40 of an inch. It was not included among the units authorized as the British Imperial system in 1824.

The line was not recognized by any statute of the English Parliament but was usually understood as 1/4 of a barleycorn, which itself was recognized by statute as 1/3 of an inch but often reckoned as 1/4 of an inch instead. The line was eventually decimalized as 1/10 of an inch, without recourse to barleycorns. The button trade used the term, redefined as 1/40 of an inch.
