The other side of the L, painted in a lighter color in the image. As you can see, you should not measure to the end of the wall since the piece or square. Where the two sides coincide will already covered by the measure.

Remember to measure from behind. In this case, it is crucial since if we did it from the front. We would let ourselves measure that same square that we talked about before belonging to side A

Write down the total meters of B.

Add A + B, and you will have a total of linear meters.

To measure a U-shaped countertop:

Make and record the measurements of A and B as we have explained in the L-shaped countertop.

The new side C, also indicated in the image in another color for clarity as possible, maybe the same length as A or be different, more or less long.

Wood is a natural material. Therefore, it has different defects and characteristics that need to know and consider for any application that you want to give it.

The grade of wood purchased by the manufacturer determines the cost and residual factor achieved.

Because grades based on the percentage of clean wood in the chart. Many of the hardwoods’ natural aesthetic characteristics not considered when calculating net yield.

Higher grades, including FAS, One-Sided FAS (FAS / 1F), and select best suited for long moldings. The joinery products such as door frames and architectural interiors. And furniture applications, which require a high percentage broad cuts.



It derived from the original “First And Seconds” grade. The FAS grade provides the buyer with long, clean cuts best suited for high-quality furniture, interior joinery, and solid wood trim. The minimum size of the boards is 6″ comprehensive and eight ‘long.

FOOT TABLE: What is a linear foot?

A board foot is a unit in which wood is measured.

One board foot equals one foot long x one foot wide x one inch thick (one foot = 0.305m, one inch = 25.4mm).

The formula to determine a board foot on a board or plank is:

(Width in inches x lake in feet x thickness in inches) divided by 12.

The percentages of clean wood required for each grade are based on this 12′ measurement.


The table above is 2 “thick, 6¼” wide, and 8 ‘long, so 6¼ “÷ 12 x 2” x 8’.

When preparing a package, the width and length of the boards are recorded. Widths greater or less than a half-inch are rounded to the nearest whole inch, while widths that equal precisely one-half inch are rounded either up or down randomly. Lengths between full foot unit increments are rounded to the next lower integer. For example, the values ​​for a 5 ¼” wide and 8 ½” long table are set to 5″ and 8 ‘.
