- Board Lengths: Common lengths are 8', 10', 12', 14', and 16'
Decking Material Options
- Pressure-Treated: Most affordable, requires maintenance

Frequently Asked Questions
What size deck boards should I use?
Common sizes are 5/4" × 6" (actual 1" × 5.5") and 2" × 6" (actual 1.5" × 5.5"). The 5/4" boards are most popular for residential decks.
How far apart should deck boards be spaced?
Leave 1/8" to 1/4" gap between boards for water drainage and wood expansion. Use spacers during installation for consistency.
Do I need to account for board width variations?
Yes, actual board widths are smaller than nominal sizes. A "6-inch" board is typically 5.5 inches wide. Our calculator accounts for this.
