Does headspace when bottling vary with different bottle sizes?

When bottling, does the amount of headspace differ depending on either the bottle size or the bottle neck width?

I have bottled with 33cl and 50cl bottles and just fill it to the top and when I pull bottling cane out, the headspace goes down to about 1.5 to 2 inches which I have found to be fine.

But I have a 5 liter swingtop that I’m thinking about using which has a wider neck.  Would I still just do the 1.5 to 2 inch headspace, or do I need to adjust because the bottle is different sized (in volume and/or in neck width).

Thanks.

I have never bottled in a 5 litre bottle so I am not sure it helps but my experience has been the same as yours, the headspace left when bottling wand is removed is sufficient. I guess it has less to do with overall volume of the bottle than with shape and diameter of the neck, If you still get 1.5 to 2 inches when wand is removed I would say you are golden.
