Measure the inside dimension of the wood beam. Using a measuring stick, measure the width of the wood beam. Lay the wood beam on a table, if necessary. For example, a 2-by-4 inch wood beam would measure 2 inches in width.
Measure the length of the wood beam. Using a measuring stick, measure from the top far edge (lengthwise) of the wood beam to the bottom far edge. For example, a 2-by-14 inch wood beam would measure 14 inches in length.
Determine the exact size. A wood beam that measure 2 inches in width and 12 inches in length has a measurement of 2-by-12.
Tip
- Custom wood beams can be purchased in sizes up to 30 inches wide by 30 inches tall at online retailers like Faux Wood Beams.com.
