How to Write Lumber Sizes

Do you actually want a piece that is 2′ x 3′?

As in any industry, there are specific rules and procedures for writing down lumber sizes. Listed below are some general rules that apply when working with lumber

  • (“) after the number represents inches
    • Example – 14″ is 14 inches
  • (‘) after the number represents feet
    • Example – 2′ is 2 feet
  • When writing the dimensions for a piece of wood, the smaller size always goes first.
    • Example – write 10″ x 14″, NOT 14″ x 10″
  • Always convert feet into inches when writing down dimensions
    • Example #1- 7.5′ should be written down as 90″
    • Example #2- 3′ 7 1/2″ should be written down as 43 1/2″
