SCMS cutting capacity and space requirements

I use my CMS for most cross cuts under 6” due to the ease of use and quick setup. However, I’ve often felt the need for additional cutting capacity.

How wide of a board can you cut with a 10” and 12” sliding compound miter saws? I think I’m now in the market for one and leaning towards a 10” because my shop is smaller but could be convinced to go for a 12’er if the increased space required is small and the additional cutting capacity is worth it.

As for brands, I’m leaning towards the Bosch, Makita, or Hitachi 10” but if I bump up to a 12” I might add Dewalt and Ridgid.

Thanks!
