I was wondering how could one approach these market sizing questions regarding the number of tennis courts in a certain country or estimating the market size for tennis balls per year?
I tried calculating the market size for tennis balls by first estimating the hours played (based on % of ppl who play tennis and then by segmenting these to 3 segments based on frequency, finally making an assumption that x% of games are single games and 1-x% doubles).
Now that I have number of hours played per year, I divide this sum by the average playtime of each ball. Does this sound reasonable?
All the tips how I can improve my thought process would he helpful!
