Hi Chris, welcome to the forums
They recommend that you go for a couple of centimetres smaller than a road size frame...hence if you ride a 56cm, then go for a 54cm.
But if you find the 56cm road frame too small, it would be worthwhile considering a 56cm framed cross bike. As with all things, try several sizes if possible to see which fits you, and go for that.
I used to ride a 58cm cross frame and I'm 6ft...fitted like a glove
