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 measurements.

(“) 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″
