Id get 15meters if your doing it yourself, a bit spare for when you fvck up.
I have guessed you are fairly novice at this or you wouldn't have asked, that why id include some extra.
What finish do you plan on using?
Satin/matt finish you have to be careful not to overstretch / overheat or you end up with glossy patches.
Carbon goes on easier I find due to the thickness, but again you have to be very cautious of not stretching the weave.
Buy a decent brand wrap (3M, Avery etc) and it will make the job much easier.
I have had experience with some of the cheap stuff on ebay and can go on great, but you have to watch out for the adhesive used, some of the cheap stuff from china uses a more permanent glue making it very difficult to get any residue off.
Although some of the cheap stuff is very good (if you go cheap, get samples first to compare)
Also make sure you get 1.52 width and not 1m or you will have many overlapping parts.
