Hamburg Hauptbahnhof is 206 m (676 ft) long, 135 m (443 ft) wide, and 37 m (121 ft) high.
It has 8,200-square-metre (88,000 sq ft) rentable area and 27,810 m² (299,300 sq ft) in total.
The clock towers are 45 m (148 ft), and the clocks have a diameter of 2.2 m (7 ft 3 in).
The track shed is constructed of iron and glass and spans the main line platforms and two S-Bahn tracks.
The platforms are reached from two bridges at street level, one at each end of the track shed; from the northern bridge by stairs and by lifts, and from the southern bridge by escalators.
Two other S-Bahn tracks and the subway tracks are in a connected tunnel system.

The Wandelhalle (Promenade Hall) is a small shopping centre with extended opening hours.
It was built in 1991 during the renewal of the beam construction.
It is located on the northern bridge and includes restaurants, flower shops, kiosks, a pharmacy, service centres and more.
The upper floor also has a gallery surrounding the hall.

Since 2008, in an effort to disperse drug dealers and users from the area, Deutsche Bahn has been playing classical music (e.g. Vivaldi's Four Seasons).
According to the German newspaper Hamburger Abendblatt this is a success.

Since 2009 the station has switched all its toilets to water-saving 3.5-litre toilets.
In 2012 they started producing Terra Preta in the basement by filtering the excrement and mixing it with charcoal and microbes.
The fluids are cleaned and nutrients are extracted.
Even pharmaceuticals can be filtered out.
