Short answer: height is really about clearance. Keep 240–270 cm between the ground and the underside of the canopy — tall enough that a 190 cm guest walks under it without performing a limbo, low enough that afternoon sun actually lands under the fabric instead of sideways under the rim. For a standard table parasol that means a 230–250 cm pole; for a cantilever model, set the canopy 240–260 cm off the deck.

Get the height wrong in either direction and the umbrella fails at its one job: too low and everyone ducks, too high and the 2 p.m. sun streams under the edge and toasts exactly the person who came to sit in the shade.
The height ladder by setup
| Setup | Pole / canopy height | Notes |
|---|---|---|
| Through a dining table | Pole 230–250 cm, canopy at ~240 | Table height adds 70–75 cm; check the pole clears the frame by 10 cm |
| Freestanding beside loungers | Canopy 240–260 cm | Tilt function matters more than height here |
| Cantilever (offset) | Canopy 240–270 cm | Needs the heavy base — see below |
| Balcony half-umbrella | Canopy 220–240 cm | Half-circles sit flush to a wall; mind the railing gap |
Base weight: the number everyone under-buys
A canopy is a sail. The base is the only thing between your lunch and a footage-worthy launch:
| Umbrella | Minimum base | Reality |
|---|---|---|
| Table parasol, 200–270 cm | 15–20 kg | The table helps; the base still does most of the work |
| Freestanding centre-pole, 250–300 cm | 25–30 kg | Under 25 kg it walks across the patio in gusts |
| Cantilever, 300 cm | 50–90 kg | The arm is a lever; check the maker's figure and believe it |
Water-filled bases are convenient and about 20% lighter in effect than they claim — plastic flexes, water sloshes. Sand or gravel filling, or a granite slab base, behaves like the weight it says on the sticker.
The shadow shift and the 30 cm rule
At noon the sun is overhead and the shadow sits politely under the canopy. By mid-afternoon the sun sits 30–40° lower and the shadow slides 30 cm or more out from under the edge — which is why a parasol perfectly positioned at 12:30 has abandoned the table by 15:00. Either buy a tilt function, reposition the base once, or accept that the 4 p.m. slot belongs to the west side of the umbrella. A 270–300 cm canopy instead of 240 cm buys you roughly an extra hour of useful shade per day.
The wind force 5 rule
Close the umbrella at wind force 5 — fresh breeze, small trees sway, flags extend, about 29–38 km/h. An open canopy at force 6 acts like a spinnaker, and the failure mode is usually the pole bending or the base skidding, not the fabric tearing. If the forecast says gusts, two minutes spent closing it saves a 60 € canopy and possibly the patio door. For cantilever models, strap the canopy closed even when base weight is generous: a closed umbrella catches a fraction of the load of an open one.
One last height nobody measures
Check the underside clearance over the chairs, not just over the table. A canopy at 240 cm clears the table, but a recliner at 45° puts a guest's head 15 cm behind the seat back — easy headroom, but the crank handle and pole base are now trip hazards inside the shadow zone. Keep the base plate 30 cm clear of the walking line and the crank out of the gap between two chairs.
