The recipe should state the volume going into fermenter. It might not state how much you'll get into bottles, since there are a few factors that can change that. As a general rule, I plan to lose about 1/2 gallon to trub/yeast cake in my batches. Which is why I put 6.5-7 gallons into primary so that I get a solid 6 gallons out. You'll want to figure out what your boil-off rate is for your hardware, or get it so that you're boil-off rate is as the recipe has listed. It's usually easier to figure out how much you boil off in an hour than try to tweak it to boil off less (in your case).
This is another case where software can really help you out. You can enter in the parameters for your hardware set and have it adjust your pre-boil volume so that you hit the volume going into fermenter. With a few tweaks, you should be able to reach the desired amount.
It's also easier to do this when you're brewing all grain, IMO... I can add more volume to the recipe, then simply add more base malt to get my volume into fermenter, ABV level, etc. without issue.
