When something is relevant to everything or everyone, we say it is
…across the board = Durch die Bank
For example: Our company had an excellent year, so the management decided to increase salaries across the board. This means everyone enjoyed an increase in their pay.
A more direct translation into German is über die Tafel. The origin of the phrase comes from horse-racing. An across-the-board bet is one where the bettor places three separate bets on one horse to win, place (come in the first three places) or show (finish) in a race, filling all the spaces on the betting board.
