Four-by-two

Four-by-two

Traditional timber dimensions were generally exact multiples of inches. With metrification and a desire to maximise timber production, dimensions are typically smaller than they were. In the 2000s a piece of framing which used to be a ‘four-by-two’ – four inches by two inches (roughly 100 by 50 millimetres) – has become a 90 by 45 millimetres.
