Under umbrella diameter

How to choose an umbrella with a suitable bottom diameter according to your needs?

Consider the number of users
Single-person use: If you mainly use the umbrella by yourself, for daily commuting, shopping and other scenes, an umbrella with a bottom diameter of about 45-60 cm (18-24 inches) is more suitable. For example, a straight-bar umbrella or folding umbrella with a bottom diameter of about 50 cm can well protect one person from rain or sun, and it will not be unable to effectively protect because the umbrella surface is too small, nor will it be bulky and inconvenient to carry because the umbrella surface is too large.
Double-person use: When you need to share an umbrella with another person, the bottom diameter of the umbrella should be between 80-100 cm (32-40 inches). Like some larger straight-bar umbrellas or golf umbrellas, the bottom diameter of the umbrella can reach this range, which can ensure that two people can be covered by the umbrella surface when walking side by side or slightly close to avoid being wet by rain or sun.
For multiple people (three or more): If it is used for family travel, small group activities, etc., you may need to choose an umbrella with a diameter of more than 120 cm (48 inches). For example, when you are outdoors, you can provide a place for your family or friends to shelter from the sun and rain. Large parasols or outdoor umbrellas for multiple people can meet this need.
Consider usage scenarios
Daily commuting: Umbrellas are usually used on city streets, bus stops, subway stations, etc. on the way to and from get off work. If you are walking, choose an umbrella with a diameter of 45-60 cm, which is convenient for moving through the crowd, easy to carry, and does not take up too much space. If you are riding a bicycle or electric bike, in order to ensure effective protection during riding, the diameter of the umbrella can be appropriately increased to 60-80 cm, which can better block rain or sunlight.
Outdoor activities: such as mountaineering, camping, fishing and other activities, choose according to the specific situation. When climbing, due to the need for light equipment, a folding umbrella with a diameter of 50-60 cm is more suitable; when camping, in order to have a larger shaded area in the camp, a large parasol with a diameter of 100-150 cm can be selected; when fishing, depending on the number of fishermen and the equipment, an umbrella with a diameter of 80-120 cm is more suitable, which can provide protection for fishermen and cover fishing gear.
Commercial activities or gatherings: In commercial activities, weddings, outdoor parties and other occasions, it may be necessary to provide umbrellas for multiple people to share. For this situation, it is more appropriate to choose a large umbrella or parasol with a diameter of 120-200 cm, which can provide a comfortable space for more people, and can also serve as a decoration to create a good atmosphere.
Consider special needs
Easy to carry: If you need to carry an umbrella frequently, such as in a handbag, backpack or storage box of a car, you should choose an umbrella with a smaller diameter under the umbrella and a smaller volume after folding. Generally speaking, a three-fold or four-fold umbrella with a diameter of 45-55 cm under the umbrella can be easily put into various bags after folding, and will not bring too much burden to travel.
Windproof performance: In areas with strong winds, the diameter of the umbrella is not the only consideration, but there is a certain correlation. A larger diameter under the umbrella may cause the umbrella to be subjected to greater resistance in the wind, so if you pay attention to windproof performance, in addition to choosing a windproof umbrella rib structure, the choice of the diameter of the umbrella should also be moderate. For example, on a windy seaside, it is more practical to choose an umbrella with a diameter of 60-80 cm and a good windproof design than to choose an umbrella that is too large.
Sun protection needs: If it is mainly used for sun protection, the larger the diameter of the umbrella, the better the sunshade effect. However, the convenience of use and the actual sun protection range needs should also be considered. For example, when sunbathing on the beach, a parasol with a diameter of 150-200 cm can provide a large shade area for lounge chairs, beach toys, etc.; while when walking on city streets, a sunshade with a diameter of 60-80 cm can meet personal sun protection needs.
