Prison cells are usually about 6 to 8
feet in size with steel or brick walls and one solid or barred door that locks
from the outside. Many modern prison cells are pre-cast. Solid doors may have a
window that allows the prisoner to be observed from the outside.
Living space per prisoner in prison
establishments: CPT standards (Strasbourg 2015)
The CPT developed in the 1990s a basic
“rule of thumb” standard for the minimum amount of living space that a prisoner
should be afforded in a cell; 6m² of living space for a single-occupancy
cell,4m² of living space per prisoner in a multiple-occupancy cell. As the CPT
has made clear in recent years, the minimum standard of living space should
exclude the sanitary facilities within a cell. Consequently, a single-occupancy
cell should measure 6m² plus the space required for a sanitary annex (usually
1m² to 2m²). Equally, the space taken up by the sanitary annexes should be
excluded from the calculation of 4m² per person in multiple occupancy cells.
Furthermore, in any cell accommodating more than one prisoner, the sanitary annexes
should be fully partitioned. Additionally, the CPT considers that any cell used
for prisoner accommodation should measure at least 2m between the walls of the
cell and 2.5m between the floor and the ceiling. This data is according to
European Committee for the Prevention of Torture and Inhuman or Degrading
Treatment or Punishment (CPT).
