Screen size recommendations for 10ft wide space?

My sim room is exactly 10ft wide. Trying to figure out the optimal screen size.

Options I'm considering:

• 10ft wide (goes wall to wall, no margin for error)
• 9ft wide (6 inches on each side)
• 8ft wide (1 foot on each side, more forgiving)

I'm a pretty straight hitter (single digit handicap) but I do miss occasionally. Don't want to be hitting the walls.

What size screens are you all running in 10ft wide spaces?
