Why is the default size of the stage 64*14?

where is your standard? There are two kinds of standard of stage bedplate. One is built by professional dancers, and the stage specification is 122*244. Because the plate is this size, in order to facilitate the construction, the bedplate size is the same, which is too small to be installed with low efficiency, and too big for two to be installed will also affect the rate. The other is small indoor activities such as weddings and press conferences in hotels. There are many sizes of countertops, but they are generally full size, generally 1*1,12*12,6*6.
