Why would one choose, say, a 2.25" drum over a 4.5"?
Fork stand rollers are more stable for obvious reasons.
I have standard rollers and fell off once when I first tried - bashed my knee pretty good. After that I used a wall to get started and put some sofa cushions on the floor just in case. Using a doorway is good advice.
Not really sure about drum size in and of itself.
Sportcrafter rollers "Resistance" drum is smaller and has magnets inside. Resistance is very realistic and it is difficult to push them past 26 or 27 MPH, just like on the road. Sportcrafter also makes a larger, free spinning "High inertia" drum which has no resistance and is heavy, like a flywheel. Some say they can actually coast on this drum.
Fixed gear is a perfect use case for rollers IMO. This is my setup.
