thats normal - you want to have some space in there to move the frames around a bit
it it was tight it would be a mess -
as the bees start work the frame wood will swell a bit from moisture and after a season that 3/4 will be about 1/2'' -
to make sure its right measure the outside it should be 16 1/4 X 19 7/8
if the lumber is 3/4 then then everything is right
