Choosing the correct weight of the umbrella base is crucial! If the base is too light, you run the risk of your umbrella falling over or even flying away if there are strong winds. If the base is too heavy, it'll make maneuvering the umbrella incredibly difficult.
The ideal base weight for table umbrellas is between 20 lbs and 40 lbs.
They only need lightweight bases as they have the additional support of the table.
Free-standing patio umbrellas need a minimum of 50 lbs in base weight.
The weight should be proportional to the umbrella's diameter.
A 6 foot umbrella should have a 60 lbs weight, a 7 foot umbrella should have a 70 lbs weight, and so on.
