Frame out garage door. Frame the rough opening to 3 inches wider than the garage door size you have selected. The pale yellowish look of pine also gives it an extra edge and something to consider. Woodworkers prefer it because they are lightweight effortless to cut stain and hit a nail into. If the door is 7 tall frame the opening 7 1 5.
If you are installing a 9 wide door the opening will be 9 3 wide. They are also rot resistant which means it will take decades to breakdown.
