For a celebration of about 200 people, the size of the tent depends on the material, content and specific scale of the event. For example, a tent of 300-500 square meters is enough for a round table of 200 people 10, that is, 20 tables of 200 square meters!
If there are tables and chairs or only a stage runway, it can be calculated as per person 1-5 square meters, and a tent of 200- 1000 square meters is needed!
