It will be an inch from the last full row to the wall, and also to the transition piece. Hopefully this picture shows it better (hard to explain) - arrow is where I'll need about 1+ inch section of LVP to reach the current transition as well as the wall (latter is less of a concern)
I could make a larger width wood transition but it would protrude into the entry area where this new flooring is. Still, might be an option for stability.
