Aircraft X was doing right closed traffic to Runway 35 and was issued at or below 5;500 feet which is our standard procedure. I reiterated the altitude as a C172 would be transitioning the airspace above him at 6;000 feet. Aircraft X took a very wide crosswind to downwind turn and briefly ended up in an area below the MVA; MSA; or minimum IFR altitude as they corrected back closer to the field.I did not anticipate Aircraft X flying their downwind that far to the east. In hindsight I could have controlled their downwind closer to the field since traffic above would not allow for a climb. After thinking about it I called the C172 traffic to Aircraft X when they were on the crosswind and that may have in turn delayed their downwind turn as they were looking for the traffic. The traffic call may have been more appropriate after they turned downwind since I already told them about the traffic once before.
SLC Tower Controller reported an aircraft took a wider than expected turn; resulting in the aircraft going into a lower MVA.
