- LEADING EDGE
- An alternative term for the dexter edge of a vertically hung banner or a gonfalon 
  – see ‘dexter edge’.
  
   
 
  Please note, that this term has been introduced by the Editors 
  as a vexillological alternative to the heraldically derived ”dexter edge”. 
  - LEAFY CROWN
- A newly introduced term – and translation of the German Blattkrone – that may be 
  used to describe a crown which is apparently formed from a series of leaves (see also 
  ‘crown of arms’, 
  ‘hamburgian coronet’, 
  ‘mural crown 1)’, and 
  ‘provincial crown 2)’).

- The edge of a sail that lies opposite to its yard, and is used (in place of “at the peak” on 
  gaff-rigged vessels) to indicate the position of an ensign when flown from a halyard running from 
  the outer end of the mainsail boom to the mast of a Bermuda rigged sailing yacht  instead of from 
  an ensign staff at the stern (see also

  ‘gaff’, 
  ‘halyard’, 
  ‘peak’ and

  - LEFT-HOISTED
- A term that may be used (in place of its heraldic equivalent) when the obverse of a 
  flag is depicted (or is manufactured) with its hoist to the observer’s left in accordance 
  with Western tradition  but see 
  ‘dexter hoist’ and the note below (also 
  ‘hoist 1)’ and 
  ‘obverse’).

  - LENGTH 
- 1) That dimension of a flag which is measured horizontally from the outside 
  edge of the hoist (generally excluding the heading), to the opposite extreme edge 
  of the fly (see also ‘Appendix I’, 
  ‘width’, ‘heading’,
  ‘hoist’ and ‘fly’).
  
- 2) The longer dimension of a stripe or band within a flag – howsoever orientated 
  (see also ‘stripe’). 
- 3) The dimension of an emblem, charge, arms, shield or badge measured horizontally, 
  when it appears on a flag – but see the note below, ‘height’
   and ‘width across’  (see also ‘badge’, 
  ‘charge’, ‘emblem’ 
  'establishment of arms'
  and ‘shield’).
  
   
 Please note that definition 3) is given with regard to the consistent 
  use of proportions when describing a flag and its charges, however, it is suggested that when 
  giving the actual dimensions of any such charge the phrase ‘width across’ should be used for its 
  horizontal measurement and the word ‘height’ for its vertical size (see also 
  ‘dimensions’ and 
  ‘proportions’).
