Before assuming a room needs a bespoke whiteboard, it is worth measuring the wall carefully and checking it against a couple of standard sizes on paper first, since the mismatch is not always as severe as it first appears. A wall that looks unusually shaped from across the room can sometimes still accommodate a standard rectangle with only a modest, acceptable gap on one side. The clearest signal that a custom whiteboard is genuinely needed is when a standard size would either not physically fit, would leave a gap wide enough to look unintentional, or would need to be positioned awkwardly off-centre to work around an obstruction. If none of those apply, a standard size may still be the simpler and more cost-effective choice, even in a room that initially seems like an obvious custom candidate.
