How many grafts will I need?

First, you’ll need the doctor to evaluate your donor area to rule out any disease that may be there. Assuming that you are over 25, the pattern looks like you are going to a Class 5A pattern. I would need to see your hair under trichoscopy to determine that, but it means that more balding is likely to occur on a limited basis in your upper crown areas. Good doctors routinely perform trichoscopy to rule out diseases of the donor area and the metrics that I am about to discuss.  It would be best to have metrics for your lifetime donor supply, including (1) donor density and (2) hair shaft thickness of the donor hairs. This will tell the surgeon what you will look like after the hair transplant, which will be shared with you. Then, a good surgeon will complete the examination by judging where your balding pattern will end up. Good planning is critical so you only expend some of your donor hair on a limited vision of where you are now. Balding is progressive, and you want to be sure that in the long term, you will always look normal and have enough hair left to follow the progressive nature of YOUR balding.
