A micro circuit

I’ve often asked this question: what size constitutes a micro layout in ‘OO’?

Should 6ft by 6ft be considered, in terms of volume, the same as 3ft by 1ft and, therefore, a micro? Is the smallest circuit of rigid geometry track, at around 2ft 8in square, including a couple of inches on the outer edges, not the micro of ovals?

I suppose the best way is not to get too hung up on the name and just accept that small is a relative term.

Here’s my favourite of small circuit designs, it captures the essence of part of Weymouth’s quayside branch in a scenic space of approximately 4ft by 3ft, with a non-scenic section beyond. The 3D diagram will show that it has a micro feel about it.
