📘 What “Post-to-Post Measurement” Means
Post-to-Post measurement refers to the distance between the structural posts that support your pergola frame.
It determines the clear opening, baseplate spacing, and footer placement required for accurate installation.
Measurements are provided in millimeters (mm), with inch (in) and foot (ft) conversions for clarity.
For wall-mounted pergolas, the same principle applies, but one side is anchored to the wall instead of supported by posts.
📐 Measurement Categories
Each Pro+ Pergola measurement guide includes:
Post-to-Post Dimensions
Distance between post edges (outer, inner, and clear opening).
Baseplate-to-Baseplate Dimensions
Exact anchor-to-anchor spacing for footers or surface mounts.
Wall-to-Post Dimensions (Wall-Mounted Models)
Distances from wall surface to front posts and baseplates.
Post Height
Total height from ground to beam, and to the top of open louvers.
⚙️ How to Use These Measurements
Use Case | How It Helps |
Planning Footers | Determine where to pour or drill concrete anchors. |
Wall-Mount Preparation | Identify correct wall-to-post projection before mounting brackets. |
Permit or HOA Documentation | Provide structural footprint and clearance details. |
Accessory Fitting | Ensure proper alignment for shades, screens, and side walls. |
💡 Tip: Always verify that your installation surface is level before marking anchor locations.

💡 Tip: For field planning, use a laser level or tape measure with both metric and imperial markings.
🧩 Installation & Planning Best Practices
Mark outer post corners first using outer-to-outer post dimensions.
Check diagonals — both should match for a perfect square or rectangle.
Allow 30 mm (≈1.2 in) tolerance for alignment adjustments.
Recommended footing size: 400 × 400 × 400 mm (16 × 16 × 16 in).
Ensure clearance above the pergola for motorized louver operation.
Use weather-resistant sealant when installing wall-mounted brackets.
Verify power outlet placement if your pergola is motorized.
