There is a lot of confusion with regard to how Town Hall levels affect matchmaking. The short answer is, it doesn't. Matchmaking is based solely on Trophies. However, the loot available to gain is affected by Town Hall level. Players get increased loot for attacking Town Halls of a higher level, and reduced loot for attacking Town Halls of a lower level. The following table describes this bonus and reduction:
Town Hall Level Difference
Percentage of Loot Available
4 or less
It's important when upgrading the Town Hall to consider the above table, because it may affect one's looting considerably. It is also advisable to upgrade everything at the current level before moving to the next.
There is some speculation that the Town Hall may make a difference at sub-200 Trophy range. However, this has not been confirmed.
