Build Your Own Summer Pergola: A Homeowner’s Guide to Choosing Cedar Lumber

A pergola can transform your backyard into a shaded retreat perfect for summer entertaining. Cedar is the go-to lumber for these projects thanks to its natural resistance to decay, attractive grain, and pleasant aroma. Here’s how to select the right cedar and get started:

  1. Pick the Right Cedar Grade

    • Select or #1 Clear: Minimal knots, smooth finish—ideal for visible beams and rafters.

    • #2 Common: Fewer clear boards but more affordable—great for posts or hidden framing.

  2. Calculate Your Board Sizes

    • Typical pergola rafters are 2×8 or 2×10 for strong overhead support.

    • Posts are often 4×4 or 6×6—choose larger posts for a more substantial look and greater wind resistance.

  3. Pre-Treatment and Finishing

    • Cedar weathers beautifully to a silvery gray, but sealing with a clear or lightly tinted exterior stain preserves color and extends lifespan.

    • Apply finish within two weeks of installation for best penetration.

  4. Installation Tips

    • Anchor Securely: Use post anchors or concrete footings below frost line.

    • Spacing Matters: Rafters spaced 16–24 inches apart create a balanced mix of sun and shade.

    • Level and Square: A perfectly level ledger board and square posts are key for a pro-looking result.
