My jumbos were 16 (or 16 1/2) inches wide by 20 inches long by 11 1/2
inches deep. They took 10 frames.

Our standards are 16 (or 16 1/2 in Canada) inches by 20 inches by 9 1/2
inches deep and take ten frames or 9 if spacers are used.  The same boxes
have the frames spaced to take 8 per box for honey supers.

Shallows over here are 4 1/2 inches deep with the other dimensions being
the same, as I recall.  Mediums are 6 5/8 inches deep.

I've cut down on how much I scrape ladder comb.  If the bees build it,
they want it.  We just remove enough to allow manipulation.

That's the truth.
