What Is the 3/4/5 Rule for Decks?
The 3/4/5 rule is a simple geometric principle that helps deck contractors Madison, WI ensure decks are square, stable, and properly sloped for drainage. In practice:
- 3 units – vertical rise (height from ground to deck)
- 4 units – horizontal run (distance along the ground)
- 5 units – hypotenuse (distance along the diagonal)
By applying this rule, deck builders Madison, WI can verify right angles and consistent slopes, preventing water pooling, uneven boards, and potential rot. It’s a small step with big impact, especially in Madison where heavy rains and snowmelt can wreak havoc on poorly designed decks. Railing contractors Madison, WI use this same principle to ensure posts are plumb and spacing is uniform for both safety and visual appeal.
