4.9 mm cell size means that on a 33.7 x 19.5 cm foundation according to this table there are 3160 cells on one side. So 6320 cells per frame.

With a cell size of 5.3 mm this is 2700 x 2 = 5400 cells. At 5.4 mm this is 2602 x 2 = 5204 cells.

920 extra cells per frame, therefore, at 4.9 mm cell size versus 5.3 mm. At 5.4 mm this differs 1116 cells.

Since we usually use 2 closing frames, we have as many frames as in a standard 'Spaarkast' hive. So also 10. But 10 x 920 or 10 x 1116 extra cells. It is clear that this also contributes to a more compact breeding nest.

We have to deduct 6% per frame. The corner that we cut from each sheet for the development of drone cells. So many drones should contain a hive in the season.
