    Possibly 30' plus from a sawmill. Depending on your requirements, is it a structural timber, because of its size , it may need intermediate supports. Whats it for.

    If your 6.3m from wall plate to wall plate and your pitch is around 25 degrees the lenght of your rafter will be around 3.8 meters thats allowing for a small overhang......any builders providers will sell 7x2 in 4.2m or 4.8m lenghts.

    Here's a handy rafter size calculator ....

    Also the home bond book is great for info on roof construction...
