The West Midlands is a landlocked county that borders the counties of Warwickshire to the east, Worcestershire to the south, and Staffordshire to the north and west.

The West Midlands County is one of the most heavily urbanised counties in the UK. Birmingham, Wolverhampton, the Black Country and Solihull together form the third most populous conurbation in the United Kingdom with a combined population of around 2.44 million. However, the West Midlands is not entirely urban; Coventry is separated from the West Midlands conurbation by a stretch of green belt land roughly 15 miles (24 km) across, known as the "Meriden Gap", which retains a strongly rural character. A smaller piece of green belt between Birmingham, Walsall and West Bromwich includes Barr Beacon and the Sandwell Valley.

The highest point in the West Midlands is Turners Hill, with a height of 271 m (889 ft). The hill is a Site of Special Scientific Interest. Barr Beacon is another hill in the West Midlands, located on the border of Birmingham and Walsall, with a height of 227 m (745 ft).

There are 23 Sites of Special Scientific Interest in the county. One of these SSSIs is Sutton Park in Sutton Coldfield, which has an area of 970 hectares (2,400 acres). As a result, it is one of the largest urban parks in Europe, and the largest outside of a capital city in Europe. The park also has National Nature Reserve status.

There are numerous rivers that pass through the county, including the River Tame. The river basin is the most urbanised basin in the United Kingdom, with approximately 42% of the basin being urbanised. The River Tame is fed by the River Rea, River Anker, and the River Blythe, which in turn is fed by the River Cole. The River Sowe and River Sherbourne both flow through Coventry. The River Stour flows through the west of the West Midlands county.
