Buy about 805 bricks for this wall.

  • The wall needs about 732 bricks; the waste allowance adds roughly 73 spare for cuts and breakages.
  • Brick count is the wall area divided by one brick face area, including its mortar joint, so the gaps between bricks are already accounted for.
  • Plan for about 18 bags of mortar mix; buy from one batch so colour stays consistent.

Next stepRound up to whole packs and keep a few spares from the same batch for future repairs and colour matching.
