Then, what is the actual size of a 2x12?

Lumber Dimensions

Nominal | Actual | Actual - Metric |
---|---|---|

2" x 8" | 1-1/2" x 7-1/4" | 38 x 184 mm |

2" x 10" | 1-1/2" x 9-1/4" | 38 x 235 mm |

2" x 12" | 1-1/2" x 11-1/4" | 38 x 286 mm |

3" x 6" | 2-1/2" x 5-1/2" | 64 x 140 mm |

Also, is a 4x4 really 4 inches? Believe it or not, there **actually** is some rhyme and reason **for** why the actual measurements of dimensional lumber don't match their names.

Actual Dimensions and Nominal Dimensions.

Nominal Measurement | Actual (inches) | Actual (mm) |
---|---|---|

2 x 12 | 1-1/2 x 11-1/4 | 38 x 286 |

4 x 4 | 3-1/2 x 3-1/2 | 89 x 89 |

4 x 6 | 3-1/2 x 5-1/2 | 89 x 140 |

Simply so, what are the standard sizes of lumber?

In Canada and the United States, the **standard** lengths of **lumber** are 6, 8, 10, 12, 14, 16, 18, 20, 22 and 24 feet (1.83, 2.44, 3.05, 3.66, 4.27, 4.88, 5.49, 6.10, 6.71 and 7.32 meters). For wall framing, "stud" or "precut" **sizes** are available, and are commonly used.

What is the actual size of a 1x4?

1x Board **Sizes** That means a 1 x 4 board is actually 3/4 inches by 3 1/2 inches.
