The Apex Pergola is available in multiple sizes, but the size name is not always the exact installed footprint.
For example, a pergola listed as 10' x 13' is the product size category. The actual outside dimensions, post placement, roof overhang, base plate position, and required clearance may vary depending on the model, configuration, and installation site.
Apex was formerly known as Master+. Some older manuals, packaging labels, or support materials may still use the Master+ name.
Before measuring your space
Before choosing your Apex size, you should measure the full area where the pergola will be installed.
Please check:
Total available width
Total available projection or depth
Ceiling, roofline, or overhead clearance
Wall height, if choosing wall-mounted
Surface type, such as concrete, deck, pavers, or other areas
Space for posts and base plates
Space around the pergola for access and installation
Nearby obstructions such as gutters, windows, vents, pipes, stairs, railings, lights, or trees
Do not measure only the furniture or seating area. Measure the full installation area.
Nominal size vs actual dimensions
Apex sizes are commonly listed using general size names such as:
10' x 10'
10' x 13'
13' x 13'
10' x 19'
13' x 19'
10' x 26'
13' x 23'
13' x 26'
These names help identify the product size, but customers should always review the official measurement guide or product diagram before installation.
The actual installed dimensions may depend on:
Freestanding or wall-mounted configuration
Single-bay or double-bay design
Post and base plate placement
Roof frame dimensions
Installation surface
Required anchoring method
Clearance around the structure
Single-bay and double-bay measurements
Apex comes in both single-bay and double-bay sizes.
A single-bay Apex Pergola has one main roof section. These are typically smaller to mid-size pergolas.
A double-bay Apex Pergola has two connected roof sections. These are larger structures and may require additional support posts.
Bay Type | What it Means | Typical Post Count - Freestanding |
Single bay | One main roof section | 4 posts |
Double bay | Two connected roof sections | 6 posts |
Double-bay sizes require extra attention during measurement because they cover a larger area and usually have center support posts.
Post placement matters
When measuring for Apex, it is important to consider the post locations, not just the roof size.
For freestanding Apex Pergolas:
Single-bay sizes typically have 4 posts
Double-bay sizes typically have 6 posts
Posts must be placed on a suitable surface
Each post must be properly anchored
Base plates need enough space around them
For wall-mounted Apex Pergolas:
Single-bay sizes typically have 2 front posts
Double-bay sizes typically have 3 front posts
The back side attaches to a suitable wall structure
The wall must be reviewed for proper support
Base plates and anchoring space
Each Apex post uses a base plate area that must be considered during measurement.
Before installation, confirm:
The post locations will not conflict with steps, drains, railings, or furniture
The surface can be drilled or anchored properly
There is enough edge distance from the slab, deck, or installation surface
The surface is level enough for installation
Footers or additional support may be needed depending on the site
Apex cannot simply be placed on top of the ground without being secured. Proper anchoring is required for safety and performance.
Wall-mounted measurement considerations
For a wall-mounted Apex Pergola, you also need to check the wall area.
Please confirm:
The wall is structurally suitable
There is enough wall height
The mounting area is clear of windows, vents, trim, gutters, lights, and pipes
The pergola will not block doors, windows, or drainage paths
A qualified contractor can confirm whether the wall can support the attachment
Wall-mounted installation should not be assumed just because the pergola fits the patio space. The wall itself must be suitable.
Clearance around the pergola
When measuring, allow extra working space around the pergola.
Clearance may be needed for:
Assembly
Anchoring
Louver movement
Motor and electrical access
Accessory installation
Future service or maintenance
Tight spaces may make installation more difficult or may not be suitable for certain configurations.
