Actual vs Nominal

*Be sure to measure - not all posts measure the same!*

Nominal generally refers to pressure treated wood.

4x4 Nominal fits 3.5" x 3.5" Post Size

5x5 Nominal fits a 4.5" x 4.5" Post Size

6x6 Nominal fits 5.5" x 5.5"

8x8 Nominal fits 7.25" x 7.25"

Actual general refers to rough lumber (not surfaced on 4 sides) or vinyl or composite posts.

Some of these post may still measure between 'Nominal' and 'Actual' sizes, particularly in Cedar material.
