Hi Mark. And welcome!! 
I have Dread sized guitars and they are big… i am not a small person nor in height or width 
And i find that the size is big and i could have done better with a smaller size. But i have somewhat got used to the size.
I can imagine that anyone smaller than me the size could be a bit of a challenge. On the other side. You can get used to about everything. I would suggest that you try out a few different sizes in a shop and go from there.
Upside on the dread though is that it has this cool boomy and powerful sound to it.
