To keep a parasol steady on the ground, the base must be weighted down enough to keep it there. The weight of a parasol base depends on the size of the parasol. As a rule, though, parasols with canopies of 3.5 – 4 metres will need a base of at least 50 kg. For parasols with 3 metre canopies, you’ll need a base of at least 40 kg, and 2.8 metre canopies need at least 30 kg in the base. Parasols smaller than these will need a base of at least 20 kg. However, if you need extra weight in your parasol base, you can add sandbags to weigh it down.
