In Tennis, how are draws characterized?

Question

For example. When an event says the draw is 56M/32Q/28D, what exactly does that mean?! What do those letters and numbers mean. Thanks.

Answer 1

The numbers stand for the size of the draw and the letters stand for the event:  (56) player-(M)ain draw (32)-player (Q)ualifying draw and (28) team (D)oubles draw.

Answer 2

the person's answer above is correct.... one more thing that i can add... the bigger the draw the bigger points you will get! :)
