Hampden is an all-seated bowl stadium, although the ground is split into four geographic sections, officially known as the North, East, South and West Stands. Due to the dominance of the Old Firm within Scottish football and their regular qualification for cup matches played at Hampden, the East and West stands are commonly known as the Celtic and Rangers ends. The East Stand has 12,800 seats on a single tier of 53 rows. The two end stands are up to 140 metres away from the pitch, due to Hampden retaining its bowl shape after it was redeveloped. This distance is almost as great as if Hampden included an athletics track, although the distance between the pitch and the two side stands is more comparable to a normal football stadium. The South Stand is the main stand of the stadium, as it holds the technical areas, dressing rooms, indoor warm-up area, executive boxes, lounges and media facilities. It has been sponsored by BT Scotland since 1998. The South Stand is also the only part of the stadium split into two tiers, although there is also a small gallery above the North Stand that has 290 seats and access to lounges. The North Stand accommodates 9,100 spectators in 46 rows. The total capacity of the stadium is 51,866. The capacity was temporarily reduced to 44,000 for the 2014 Commonwealth Games, as the running track raised the field level by 1.9 metres.
