Rectangular Cantilever Umbrellas

Most cantilever umbrellas have a square canopy. That works well when the furniture underneath is roughly symmetrical — a round dining table, a square lounge grouping, a cluster of chairs. But a lot of Australian outdoor living doesn't follow that geometry. Long rectangular dining tables. Narrow alfresco decks running alongside a house wall. A sun lounger arrangement that goes three deep in one direction. For those spaces, a square canopy creates an awkward mismatch: either the short sides overhang excessively while the long ends leave seats exposed, or the umbrella sits off-centre to compensate.

A rectangular cantilever umbrella solves that mismatch directly. The 3×4m canopy extends four metres in one direction and three in the other — twelve square metres of shade in a footprint that naturally mirrors the geometry of most Australian outdoor dining tables and narrow deck configurations.

The 3×4m format earns its place in a specific set of outdoor situations where a square canopy falls short:

• Long rectangular outdoor dining tables seating 8 to 10 people, where a square canopy leaves the end chairs partially unshaded from mid-morning onward
• Narrow alfresco decks that run along a building or fence line — the 4m length follows the deck geometry while the 3m width stays within the footprint
• Pool surrounds with sun loungers arranged end-to-end rather than side by side
• Outdoor kitchen setups where the cooking zone and the eating area are arranged in a line rather than a cluster

If your outdoor space is more symmetrical — a square lounge grouping, a round dining table, a pool surround where loungers sit side by side — a square canopy tends to be a better geometric match. Our 3m Cantilever Umbrellas covers that format, or browse the full Outdoor Umbrellas range for the complete picture across all canopy shapes and sizes.

The rectangular cantilever umbrellas in this collection use the same structural approach as the square-format models: powder-coated aluminium frame, UPF 50+ rated canopy, dual-vent construction at the apex, and 360° rotation to track the sun across the full arc of the Australian day without moving the furniture underneath.

One practical implication of the rectangular format worth understanding: the orientation of the canopy relative to the mast matters more than on a square model. Because the canopy is longer in one direction, positioning the long axis parallel to your table — rather than perpendicular to it — is what gives you full coverage at the ends. The 360° rotation mechanism makes this straightforward to dial in once the umbrella is positioned, and to readjust across the day as the sun moves.

All frames are powder-coated aluminium: rust-proof, salt-air resistant, and low-maintenance across coastal and inland Australian conditions.

At 12m² of canopy, a rectangular cantilever umbrella catches significantly more wind surface than a standard 9m² square model. Combined with the offset arm geometry, that translates to higher lever forces at the base — and higher ballast requirements than you might be used to if you've previously run a smaller cantilever or a centre-pole umbrella.

For a 3×4m rectangular cantilever in a sheltered suburban position: 100 kg minimum. In coastal, elevated, or consistently exposed positions — afternoon sea breezes, southerly exposure, rooftop or elevated decks — 120 kg is the appropriate starting point. These aren't conservative estimates; they're the weight figures at which the base actually holds position under the load conditions an Australian summer regularly produces at this canopy size.

Our Outdoor Umbrella Bases & Weights collection includes modular ballast systems rated for the large-format cantilever, with plate options that let you build up to the required weight incrementally and reconfigure if the umbrella moves positions.
