Pedestal Spacing Chart for Pavers | Height Guide for Deck Pedestal Systems

The number of pedestals required depends on the size, thickness, and load requirements of the pavers being installed. In most applications, pedestals are positioned at each corner of the paver. Larger format pavers or heavier load conditions may require additional support at midpoints or center locations. Always follow manufacturer guidelines for proper spacing and support.

Pedestal Spacing & Height Chart for Pavers and Rooftop Deck Systems

Pedestal spacing and quantity may vary depending on paver size, thickness, and load requirements. Always follow the paver manufacturer’s guidelines and recommended spacing for proper support and long-term performance.

Typical Pedestal Layouts for Common Paver Sizes (Spacing Guide)

Common paver sizes include 24" × 24", 24" × 48", 30" × 30", 36" × 36", and 48" × 48".

Pedestal layout and spacing will vary depending on paver dimensions, thickness, and load requirements.

How to Calculate Pedestals for a Paver Deck (Simple Formula & Example)

For 24" × 24" pavers, pedestal quantities can be estimated using a simple formula:

Pedestals Needed = Paver Count + (Perimeter ÷ 2) + 10% Extra

This method provides a practical estimate for most rooftop deck and terrace applications.

Deck Joist Spacing for Pedestal Deck Systems (16"–24" On Center)

Deck joists are typically spaced 16" to 24" on center, depending on the joist manufacturer’s specifications and the type of decking system used. Proper joist spacing is critical to ensure structural support, stability, and long-term performance. Always follow manufacturer guidelines when installing pedestal-supported deck systems.
