Defining "6 6" in Post Dimensions
The term “6 6 post” generally indicates a post that is 6 inches by 6 inches in cross-sectional dimensions. This notation is common in woodworking and metalworking industries to describe the width and depth of a post. Therefore, a “6 6 post” is a square post measuring 6 inches in width and 6 inches in depth.
Common Contexts Where "6 6 Post" Is Used
- Wooden fencing: Posts are often categorized by their dimensions, with 6x6 posts being a common choice for sturdy fencing.
- Deck construction: 6x6 posts are frequently used as support posts for decks and porches.

Standard Dimensions of a 6 6 Post
Measurements in Inches and Millimeters
- In inches: A 6x6 post measures exactly 6 inches in width and 6 inches in depth.
- In millimeters: Since 1 inch equals 25.4 millimeters, a 6x6 post is approximately 152.4 mm by 152.4 mm.
Actual vs. Nominal Size
It’s important to note that the nominal size of a post (e.g., 6x6) often differs slightly from its actual size due to manufacturing processes and finishing. For example:
- Nominal size: 6 inches by 6 inches
- Actual size: Usually around 5.5 inches by 5.5 inches (for lumber) or slightly less for metal posts after finishing.
In the case of lumber, a 6x6 post is typically a 2-inch thick board planed down from a larger rough-cut piece, resulting in an actual dimension of approximately 5.5 inches.
