You'll be fine provided the top of the screen doesn't exceed a 15 degree vertical viewing angle. It's usually not the size that is a problem, but the height - looking up for prolonged periods cases neck ache, so make sure the screen isn't too high. The width won't be a problem.
Most commercial theatres have a seating range between 2 to 4 times the screen height, and you're at 2.26. That's closer than most people sit, but that's usually because most commercial theatre screens tend to provided higher VVA at those distances which makes it uncomfortable.
For a 3.5m viewing distance, keep the top of the screen below 94cms from seated eye level and you should be ok.
