• Live load (weight of people and objects on the deck)
• Spacing between joists
• Species and grade of lumber
• Type of fasteners used
• Moisture content of the wood

Each of these factors must be taken into account when determining the appropriate span for your deck floor joists.

How to Read and Use Deck Floor Joist Span Tables

Deck floor joist span tables are relatively easy to read and use, although they can be a bit intimidating at first. Typically, the tables list the maximum allowable span for different types of lumber, based on the factors mentioned above. To use the table, you will need to know the size and spacing of your joists, as well as the species of wood you plan to use. Then, simply locate the appropriate chart and find the maximum allowable span for your specific situation.

Common Deck Floor Joist Spans for Different Types of Lumber

The maximum allowable span for deck floor joists will vary depending on the type of lumber used. Here are some common spans for different types of wood:

• Pressure-treated pine: 2x6 joists at 24 O.C. can span up to 11'9; 2x8 joists at 24 O.C. can span up to 13'1; 2x10 joists at 24 O.C. can span up to 15'1.
• Cedar: 2x6 joists at 24 O.C. can span up to 9'11; 2x8 joists at 24 O.C. can span up to 11'7; 2x10 joists at 24 O.C. can span up to 13'5.

How to Calculate Deck Floor Joist Spans for Your Project

If you plan to use a type of lumber that is not listed in the deck floor joist span tables, you can still determine the appropriate span by using a span calculator or consulting with a structural engineer. To calculate the maximum allowable span, you will need to know the size and spacing of your joists, as well as the species and grade of lumber you plan to use. The calculator or engineer can then provide you with a safe and accurate span based on your specific situation.

What Happens When Deck Floor Joist Spans Are Exceeded?

Exceeding the maximum allowable span for deck floor joists can lead to a range of problems, from sagging and bouncing decks to outright collapse. This can result in serious injury or even death, as well as costly repairs and legal liabilities. It is essential to follow the guidelines provided by the deck floor joist span tables to ensure a safe and structurally sound deck.

Alternatives to Traditional Deck Floor Joists

There are several alternatives to traditional deck floor joists that can offer improved performance and durability.

Composite decking materials, such as PVC or composite lumber, can also offer improved resistance to moisture, fading, and staining.

Tips for Maintaining Adequate Deck Floor Joist Spans Over Time

To maintain adequate deck floor joist spans over time, it is essential to use high-quality lumber, fasteners, and other materials. Regular maintenance, such as cleaning and sealing the deck, can also help prevent rot, decay, and other issues that can compromise the integrity of the structure. Finally, it is important to consult with local building codes and professionals to ensure compliance and safety.

Consulting with Local Building Codes and Professionals for Compliance and Safety

Before embarking on any deck construction project, it is essential to consult with local building codes and professionals to ensure compliance and safety. This includes obtaining any necessary permits, following local regulations and guidelines, and working with qualified contractors and engineers to ensure a safe and structurally sound deck.

Deck floor joist span tables are an essential tool for any DIY enthusiast or professional builder looking to construct a safe and sturdy deck.
