I would think it would be fine, most I've seen (and needed myself) is 3-4" on all sides. BUT check with your LA as it will depend on what kind of leaders and side clamps she/he is using.
I just brought one to an LA that required 4" (it's too big for my frame). I was able to find 115" fabric which meant I would only have 3.5" on the sides and she was OK with that.
