What Size Cantilever Umbrella Do You Need

Short answer: Match the canopy to the table, not the other way round. A 2.5m canopy suits a four-seat setting, 3.0m suits six, and 3.5m to 4.0m covers eight to ten. Published size charts disagree with each other by a wide margin. Most ignore canopy shape and the type of mount, and almost none connect the size decision to the base weight that same size then demands.

Buying the bigger canopy for more shade is the instinct that causes the most trouble. Every extra half-metre of fabric is also extra sail area; the base has to grow to match it, in the cantilever umbrella range we stock.

Why every size chart online disagrees with the next one

Checked against the same “four to six people” bracket, one competitor guide asks for a 10 to 12 foot canopy. Another asks for only 8 to 9 feet. A third puts a 3.5 metre square at six seats, where a fourth calls that same size a two-person umbrella. None of them account for canopy shape consistently. A square canopy and an octagon of the same width cover different actual areas. A centre-pole umbrella loses table space to the pole itself, in a way a cantilever does not; its canopy floats clear on an offset arm.

That gap is worth resolving with real numbers rather than another rough chart.

Size by seating, on the range My Acre actually stocks

Two umbrellas at the same nominal 3.0 metres do not always seat the same number. A rotating cantilever holds its canopy clear of the table on an offset arm, so the seating underneath uses the full footprint; a centre-pole umbrella loses the space its own pole occupies. That difference, not marketing, is why a 3.0m figure varies between mount types more than any chart online explains.

The base problem nobody’s chart mentions

Real owner reports describe the same failure again and again. A base that sounds generous on paper, sometimes over 100 kg, still proves too light once a cantilever’s offset leverage is factored in; a cantilever fights a lever rather than resisting weight straight down. Sizing up the canopy for more shade multiplies that leverage further. A published wind rating is a wind-tunnel figure, not a promise about a particular gusty afternoon. Owners describe making a live call to close the umbrella regardless of what the rating says.

Ring Hayden on 1300 515 620 before ordering a size that is close to the edge of what a table or a space can actually take. He will check the canopy size against the base your setup needs, not just the seats it covers. Our guide on how much weight a cantilever umbrella base actually needs works through the numbers by tier.

The Shadowspec range, size by size

No floor space to spare changes the answer entirely. The Retreat mounts to a solid wall and needs no base at all, which the sizing table above assumes there is room for.

The honest verdict

Size to the table first. Then check the base the resulting canopy actually needs before ordering it; the two decisions are really one decision. A generously sized umbrella on an undersized base is worse than a smaller one properly anchored.
