Understanding Deck and Patio Planning
Planning a deck or patio requires careful consideration of dimensions and materials. Here are some key factors to consider:
Material Requirements
- Decking boards: Typically need 10% extra for waste and cuts
- Concrete (for patios): Calculate cubic yards needed (depth × square footage)
- Support beams: Usually spaced 16" on center
Common Dimensions
- Small deck/patio: 12' × 12' (144 sq ft)
- Medium deck/patio: 16' × 20' (320 sq ft)
- Large deck/patio: 20' × 20' (400 sq ft)
