Choosing a patio umbrella comes down to canopy size against the table, market or cantilever to suit where the pole can stand, fabric that holds its color, ribs that survive wind, and a base heavy enough for all of it. Here is each decision in order.
The short answer
Choose a patio umbrella in this order. First the canopy size, set by the table or the seating it has to shade. Then the type: a market umbrella with a center pole if it stands through a table hole, a cantilever if the shade has to float over a sofa, loungers or a table with no hole. Then the comfort features, a crank to open it and a tilt to follow a low sun. Then the fabric, which decides whether the color lasts one summer or ten. Then the frame, which decides whether a gust bends it. Then, and this is the step most people skip, a base heavy enough for the size and type. An umbrella that is right in every other way but sits on a light base is the one that ends up in the pool or the neighbor’s yard.
Size: start from the table
A canopy should extend about 2 feet past the table edge on every side, so the canopy diameter wants to be 4 to 5 feet more than the table width. In practice that gives four common sizes. A 7.5 foot canopy suits a bistro set or a round table up to about 36 inches, shading two to four chairs. A 9 foot canopy, by far the most common size, covers a 42 to 54 inch round table or a 60 to 72 inch rectangle with four to six chairs. A 10 foot canopy handles a 60 inch round with six chairs. An 11 foot canopy covers a 72 to 84 inch rectangle or a conversation set with six to eight seats. Long rectangular tables are better served by a rectangular canopy, usually 6.5 by 10 feet or 8 by 10 feet, than by an oversized round one. Measure the table hole too: most are 1.5 to 2.5 inches, and most 9 foot poles are 1.5 inches, so a thin pole in a wide hole wobbles unless the table came with a reducer ring. Check overhead clearance, since a 9 foot market umbrella stands about 8 feet tall and a cantilever arm can swing higher.
Market or cantilever
A market umbrella has a straight center pole, and it either drops through the hole in a dining table into a base underneath or stands in a freestanding base beside the chairs. It is lighter, cheaper, simpler to open and far easier to store, and the base can be modest because the table helps hold it. The cost is the pole in the middle of the table and shade that you move by moving the whole umbrella. A cantilever, also called an offset umbrella, hangs the canopy from an arm on a pole set to one side. It shades a sectional, a pair of loungers, a hot tub or a table without a hole, and most models rotate through 360 degrees and tilt from the arm so the shade follows the sun without the base moving. The trade-offs are real: it costs more, it weighs more, it needs a wide base that is far heavier because the canopy hangs off center and gives the wind leverage, and it takes more space to store. For a dining table with a hole, buy a market umbrella. For a lounge area, buy a cantilever and budget for the base.
Tilt and crank
A crank lift is standard on 9 foot canopies and up, and worth having on anything bigger than 7.5 feet, since a pulley or a push-up pin on a big canopy is awkward at head height. Tilt matters more than it sounds. At noon a flat canopy shades the table; at 9 in the morning and after 4 in the afternoon the sun comes in low from the side and a flat canopy shades the ground behind the chairs. Push-button tilt kinks the pole at a joint below the hub, collar tilt turns the crank past full open to tilt without reaching up, and auto tilt is the same idea with a crank handle. Cantilevers tilt with a handle on the arm. One caution: a tilted canopy catches wind like a sail, so tilt it only in calm weather and close it when a breeze picks up.
Canopy fabric
The fabric decides how the umbrella looks in its third summer. Solution-dyed acrylic, of which Sunbrella is the familiar name, has the color mixed into the fiber before it is spun, so the sun cannot bleach it out from the surface; makers back it with fade warranties of 5 to 10 years, it sheds water and resists mildew, and it is the most expensive option. Polyester is piece-dyed after weaving, costs a fraction as much, and in strong sun fades noticeably in one to two seasons, often starting at the top panels; it is a sensible choice for an umbrella that goes up for parties and lives in a garage the rest of the time. Olefin sits between the two in both price and fade resistance. Whatever the fiber, look for a UPF 50+ rating, a fabric weight stated in grams per square meter (heavier is sturdier, with 180 to 250 common on polyester), double-stitched seams, and a canopy that can be bought as a replacement on its own, which turns a faded umbrella back into a new one for a fraction of the cost.
Ribs, pole and vents
Aluminum is the standard frame: light, powder-coated and rust-free, with the weakness that an aluminum rib bent by a gust stays bent. Fiberglass ribs flex in wind and spring back, which is why they appear on umbrellas sold for beaches and open yards, and they cost more. Wood poles and ribs look right on a traditional patio, weigh more, usually skip tilt, and need oiling to avoid cracking. Steel is strong and cheap and will rust at the joints after a few seasons unless the coating is perfect. Count the ribs: six is fine on a 7.5 foot canopy, eight is standard on 9 feet and up. Pole diameter should grow with the canopy, from about 1.5 inches on a 9 foot to about 1.9 to 2 inches on 10 and 11 foot models. A vent at the crown, a second small canopy over an opening at the top, lets gusts pass through instead of lifting the whole umbrella, and lets hot air escape; a double vent is better where wind is routine.
Base weight rules
Base weight depends on size and on whether the table shares the load. A market umbrella standing through a table needs about 30 to 50 pounds under it, since the table steadies the pole. A freestanding market umbrella needs about 50 pounds at 7.5 feet, 50 to 75 pounds at 9 feet, and 75 to 100 pounds or more at 10 and 11 feet. A cantilever needs at least 150 pounds, with 200 to 300 pounds safer in an open yard, or a mounting plate bolted to a deck or a concrete slab. Cast iron and concrete bases are compact and heavy; resin bases are hollow and filled on site, and sand fills heavier than water (a base rated 50 pounds with water is about 65 to 70 pounds with sand). Check that the base tube fits the pole diameter and has a tightening knob, and look for wheels on anything over 75 pounds.
Wind and storage
No patio umbrella is rated to stay open in a storm. Close it when gusts pass about 20 mph, close it whenever you leave the yard, and strap the closed canopy with its tie. Buy a storage cover, a zippered sleeve with a rod that slides it over the closed canopy; it keeps bird droppings and pollen off and stops mildew. Dry the canopy fully before covering it, and over winter bring the canopy indoors or into a dry garage while the base stays outside. Kept that way a good acrylic canopy outlasts two or three polyester ones.

FAQs
A 9 foot canopy. The rule is a canopy diameter about 4 to 5 feet larger than the table, so a 48 inch round takes 9 feet, a 60 inch table takes 10 or 11 feet, and a bistro table takes 7.5 feet.
About 50 pounds for a 7.5 or 9 foot market umbrella standing through a table, 75 to 100 pounds for a 9 to 11 foot market umbrella standing on its own, and 150 pounds or more for a cantilever, with 200 plus better in open sites.
If the umbrella stays up all season in full sun, yes. The color runs through the fiber, so makers warrant it against fading for 5 to 10 years, while polyester fades noticeably in one to two summers.
Market through a dining table with a hole. Cantilever over a sectional, lounge chairs or a table without a hole, as long as there is room for the base and a budget for a much heavier one.
