How long to visit the Colosseum
The honest answer depends on whether you are seeing the Colosseum alone or all three sites in the bundle.
Colosseum alone
Budget 45 to 75 minutes for a walk through the Colosseum itself. Seeing every level at an unrushed pace takes 2 to 2.5 hours.
All three sites
The Colosseum, Roman Forum and Palatine Hill together, unrushed, take 4.5 to 5 hours in total. A guided version of all three runs about 3 hours, against roughly 1 hour for an express guided tour of the Colosseum alone.

Queue time
Without a timed ticket, the peak-season queue itself can run 1 to 2 hours, before you have seen anything. Every ticket type on this site includes a booked entry slot, which skips that wait. Check opening hours to plan which slot to book.
