Deck Support Calculator

Understanding Deck Support

Proper deck support is crucial for safety and longevity.

  • Post Spacing Distance between support posts for optimal load distribution.
  • Post Size Minimum post dimensions based on height and load.
  • Beam Size Required beam dimensions to support deck loads.
  • Footing Size Foundation requirements based on soil and loads.

Design Considerations

Load Distribution

Consider both live and dead loads in calculations.

Soil Conditions

Verify soil bearing capacity for footing design.

Weather Exposure

Use weather-resistant materials and proper drainage.

Building Codes

Meet local requirements for deck construction.

Material Selection Guide

  • Posts Pressure-treated lumber or metal posts for durability.
  • Beams Built-up lumber or engineered beams for strength.
  • Footings Concrete with proper depth for frost protection.
  • Hardware Galvanized or stainless steel for corrosion resistance.
