Calculate the square footage of your yard. Determine which type of seed you will be using. There are some variations in amount of seed needed depending on the type of seed used. Some common types are Kentucky Bluegrass and Tall Fescue. Kentucky Bluegrass requires two to three pounds for each 1,000 square feet. Tall Fescue requires six to eight pounds for each 1,000 square feet. Calculate the total pounds of seed needed. Divide the total square feet of your lawn by 1,000. Then multiply that number by the pounds of seed needed per 1,000 square feet.
You have to check with the vendor that sells the type of seed for your area based on what you want to use it for and the predicated growing conditions. They will let you know how many pounds it may take to over-seed based on how many square feet you are trying to cover. For example, in the past to over-seed a green for winter time play with a blend of 80/20, I have used as little as 4 pounds per 1000 square feet and as much as 12 pounds per 1000 square feet. A home owner would normally use 6-8 pounds of Rye grass in my area to over-seed their lawn. A Golf ccourse would also use a special seed that would only grow in the winter and die in early spring to not return.

That will vary tremendously depending upon what kind of grass you plant. Your best bet is to make a decision first on what kind of grass you want, then follow the directions on the package.
Go to the store, determine what kind of grass you want, read the information on the package and it will tell you how many square feet the bag will cover.
