Hi kelly from looking at the picture of your rose - I would say that your rose is a climber rather than a floribunda or hybrid tea - which as it is a climber will need a slightly different approach to pruning compared to that of other rose varieties.
Although there are several types of climbing roses the majority these days are what are known as modern climbers which generally grow to around 10 - 12 ft - but saying that there are some varieties that can grow way bigger than that.
As for pruning your climbing rose - I wouldn't do anything too drastic as you could spoil the look of your rose - particularly as most modern climbing roses don't generally need to be pruned much at all - and even then only light pruning is needed mainly for height, shape and to keep them looking tidy - which is done yearly in late winter to early spring - by removing all the dead wood, suckers and cross over stems - however this is only done once the rose is established - as climbers are best not pruned or at least as little as possible during their first 2 - 3 years of growth - as cutting back the main stems too early - will totally alter the look of the rose - as it will start to grow into a rather ugly unsightly shape.
So as your rose is currently around 6 - 7 feet tall - I would hazard a guess that it is still not fully established - which means that if you cut the main stems too drastically now - you could totally spoil the look of your rose - which would be a great shame particularly as its currently looking very healthy and attractive as it is - which is why I think rather than trying to reduce the size of your rose - it would be much better to leave it be and train it or fan it out where it is that you want it to grow on the wall.
