Hi Richard,
I use full deep frames and average about 2.2 kg of extracted honey per frame that is about 90-95% capped. In other words 10 frames will put 22kg of honey in the jars. According to Wikipedia, an ideal frame is about 55% the size of a deep frame so you could expect about 1.2 kg of extracted honey per frame.
Honey has a density of 1.6 so 1.6kg of honey will require a 1 litre jar or put another way, you will need a jar of 750ml (1.2/1.6) for each frame you extract.
Hope that makes sense.
Regards
