Post Caps for Every Size: 4x4, 6x6, 8x8, and Custom
Looking to protect your deck or fence posts while adding style? Deck Accent offers a full range of 4x4 post caps, 6x6 post caps, and 8x8 post caps in designs for every taste. Choose from solar, wood, Azek, glass, copper, aluminum, and low-voltage lighted post caps.
While 4x4 and 6x6 are the most popular, we can also make custom post caps for sizes like 3x3, 8x8, 10x10, and more — often at no extra charge. That way, even non-standard posts can be topped with a perfect fit.
Why Our Wood Post Caps Last Longer
Each wood post cap starts from a solid block of wood, which is precision-cut and shaped. We then add decorative molding — four mitered pieces, glued and stapled — to ensure it holds for the lifetime of the cap. Depending on the style, molding extends 1-1/8" or 1-5/8" down for a clean finish.
How to Measure for a Post Cap
Outside measurement: About 1-1/4" larger than your post size.
Example: A 5-1/2" post needs a cap around 7-1/4" square.
For flat designs (like the Island Post Cap), the top flat area matches the exact post size.
