How Big is a Prison Cell – Life In Prison Cells

Prison cell size is an important consideration in corrections. The amount of space afforded to inmates can impact their mental health, behavior, and overall quality of life behind bars. However, cell sizes can vary greatly between different facilities and jurisdictions. This article will provide an overview of typical prison cell sizes, factors that influence cell size, and the debate around proper cell space in correctional settings.

Typical Prison Cell Sizes

Prison cell sizes can range from as small as 45-80 square feet to as large as 120-160 square feet. The American Correctional Association (ACA) recommends that cells be at least 70 square feet. However, not all jurisdictions follow these guidelines. Here are some examples of typical cell sizes:

  • Minimum security – 70-120 square feet. Minimum security prisons house inmates deemed lowest risk, so cells may be on the larger side.
  • Medium security – 70-100 square feet. This is the most common cell size in state and federal prisons. Cells are small, with just enough room for bunks and a toilet/sink.
  • Maximum security – 45-80 square feet. Also known as “administrative segregation,” these isolated cells are extremely small to limit movement and privilege.
  • Supermax – 80-120 square feet. Supermax facilities house dangerous inmates in solitary confinement with very limited mobility and amenity.

Federal prisons tend to have slightly larger cells than state facilities. The Federal Bureau of Prisons reports an average cell size of 88 square feet in their penitentiaries.

Factors That Influence Cell Size

Several key factors determine just how big or small an inmate’s cell will be:

  • Facility age – Older prisons tend to have smaller cells, sometimes as small as 40-50 square feet. Newly constructed prisons are built to modern standards with larger cell sizes.
  • Level of security – As mentioned above, maximum security cells are smaller than minimum security ones to limit inmate mobility. Higher security levels warrant tighter quarters.
  • Facility population – Overcrowded prisons can lead to cramped conditions with less space per person. Maintaining smaller populations allows for more generously sized cells.
  • Location – Cell size regulations and standards vary between states. Rural prisons may have different cell sizes than urban ones.
  • Prison design – Some facilities are designed with small, narrow cells while others provide larger open dormitory housing among inmate populations with fewer barriers.

While cells continue to shrink in many facilities, inmate living space remains a critical human rights issue.

Controversy Over Cell Space Standards

The amount of minimum space afforded to inmates in cells has been a topic of recurring debate and legal action. Correctional authorities argue smaller cells are necessary for safety and control in the nation’s crowded prisons. However, inmate advocates and civil rights groups contend current cell sizes constitute cruel and unusual punishment. Some key elements of this debate include:

  • Mental health – Confined to a 6×8 foot cell for 23 hours per day can cause psychological damage, according to mental health experts. Lack of mobility is tied to depression, anxiety, and higher rates of suicide among inmates.
  • Privacy – Small cells housing two to three inmates provide no privacy or quiet time. Constant noise and exposure to cellmates in tight quarters creates stressful conditions.
  • Health risks -crowded cells increase the spread of infectious diseases. Poor ventilation raises safety issues. Cells are not properly cleaned and maintained.
  • Violence – Close quarters lead to increased friction and violence between cellmates. Corrections officers point to smaller cells as an important disciplinary and management measure.
  • Rehabilitation – Maximum security cells allow little opportunity for rehabilitative programming, exercise, education, or social contact–deemed vital for successful re-entry.

While corrections officials emphasize safety and security priorities, advocates argue current standards violate the constitutional ban on cruel and unusual punishment. The debate continues with mounting legal action seeking minimum space requirements.

A Typical Cell Layout

To understand how small prison cells can be, it helps to visualize a typical cell layout. While cells vary between different security levels, here is an example layout of a standard correctional cell:

  • 5-6 feet wide
  • 8-10 feet long
  • 70-80 total square feet
  • 6-7 foot high ceilings
  • One bunk bed with thin mattress, pillow, and standard issue linens
  • Combination toilet and sink connected to wall
  • Desk and seat molded from concrete
  • Storage shelf for personal belongings
  • Small window with security mesh
  • Heavy steel door with small window and food slot
  • Concrete walls and flooring

With two inmates sharing this confined space, there is very limited room to move about. The bunks, desk, toilet area occupy most of the floorplan. Cells are sparse by design with minimal furnishings or amenities. Open floor space is extremely limited. Most movement is restricted to changing position on the bed, using the toilet, or pacing the short length of the cell. Temporary reprieve comes from exiting the cell for meals, showers, exercise, or programs.

Daily Life in a Small Prison Cell

Spending nearly 24 hours a day in a 6×8 foot cell can be an intense experience. The reality of living in such a confined space involves strict routines and deprivation. Here is a look at typical daily life inside a small maximum security prison cell:


  • 5:00 am – Wake up to alarms sounding down the cell block. Guards begin shouting to inmates.
  • 5:05 am – Take turns using the toilet with cellmate before line up for breakfast. Sinks turn on to wash hands and face.
  • 5:20 am – Doors unlock simultaneously down the row. Line up at cell door for pat down search before proceeding to breakfast.
  • 6:00 am – Return from breakfast line to locked cell.


  • 11:30 am – Doors open for lunch line. Receive tray of food through slot to eat inside cell.
  • 12:00 pm – Locked in cell again until dinner. Pass time reading, writing letters, sleeping, or talking quietly with cellmate.
  • 12:30 pm – Once a week, released to outdoor recreation area for 1 hour. Other days remain confined.
  • 2:00 pm – Access to TV or radio programs passed through cell bars if permitted.


  • 4:00 pm – Dinner line rotation. Return to cell until next morning.
  • 5:00 pm – Locked in for the night. No movement allowed until breakfast.
  • 9:00 pm – Lights shut off. Try to sleep despite noise and discomfort.

Daily life inside some maximum security cells amounts to extreme isolation and inactivity. Sensory deprivation and loss of environmental stimulation can occur. The monotonous routine and tight living quarters often lead to tension between cellmates. Maintaining mental health under these conditions proves challenging.

Historical Changes in Prison Cell Size

Prison cell size and design has evolved considerably over the decades. Cells built more than a century ago were extremely cramped, dark, and lacking sanitation. Progressive reforms led to more spacious and humane cell standards:

EraCell SizeNotes
1790s20-30 sq ftNo natural light or ventilation. Shackled inmates.
1850s30-50 sq ftTiny, dark cells. No sanitation.
1890s50-70 sq ftWindow added for light and air circulation.
1930s70-80 sq ftElectric lighting installed. Bunk beds added.
1970s80-120 sq ftRegulations on minimum sizes.
2000s70-160 sq ftLarger capacities in new prisons.

Modern US prison cells remain small but improved with lighting, ventilation, hygiene, and basic living amenities. Continued pressure from advocacy groups pushes for further increasing of cell sizes in many correctional systems.

Recommended Cell Size Guidelines

So what exactly constitutes an adequately sized prison cell? Here are some general guidelines from correctional standards organizations:

  • American Correctional Association – minimum of 70 square feet of floor space for single cells. Approx. 35 sq ft of floor space per inmate in shared cells.
  • Federal Bureau of Prisons – cells must have at least 25 feet of clear wall length, and approximately 75 square feet of floor space.
  • United Nations – minimum of 76 square feet individual cells, and 35 square feet per inmate for shared cells.
  • European Committee for the Prevention of Torture – minimum cell area of approximately 63 square feet with at least 43 square feet of free moving space excluding fixtures.

Based on these recommendations, many current US prison cells fall below advised standards, especially in maximum security facilities. Continued legal advocacy cites these guidelines in pursuing larger cell capacities.

Measuring a Prison Cell

Figuring out the area of a prison cell requires measuring length and width to calculate total square footage. This involves some simple math:

  1. Use a measuring tape to measure the cell’s length from one end to the other. For example, 104 inches.
  2. Next, measure the width from one side to the other. For example, 75 inches.
  3. Convert the length and width measurements to feet by dividing by 12 inches. In this example:
    • Length: 104 inches ÷ 12 inches = 8.7 feet
    • Width: 75 inches ÷ 12 inches = 6.3 feet
  4. To determine total square feet, multiply the length times the width. So in this example:
    • 8.7 feet x 6.3 feet = 54.9 square feet

This sample cell has a total floor area of about 55 square feet. That’s well below ACA recommended standards for minimum security single occupancy cells. By taking these measurements, you can get an accurate sense of the confined space within a prison cell.

Impact of Cell Size on Inmates

It’s clear US prison cells are often extremely small, but how does limited square footage actually impact inmates locked inside these cramped quarters nearly 24/7? Here are some of the physical and psychological effects:

Physical Effects

  • Muscular atrophy – Lack of movement can cause muscle deterioration and weakness.
  • Poor eyesight – Cells have limited natural light needed for healthy vision.
  • Sleep deprivation – Discomfort and noise make resting difficult despite confinement fatigue.
  • Skin rashes/infections – Tight quarters and lack of ventilation increase skin irritation and infectious outbreaks.
  • Cardiovascular effects – Heart conditions may develop from constant sitting, laying, or standing with little exercise.

Psychological Effects

  • Anxiety/frustration – Extreme boredom and isolation in a small space cause psychological strain.
  • Depression – The monotonous routine and sensory deprivation of small cells can lead to mental health issues.
  • Aggression/violence – Close quarters breed tension between cellmates that sometimes escalates to assaults.
  • Suicidal tendencies – The stress of confinement in a small cell pushes some inmates to self-harm or suicide.
  • Mental deterioration – Schizophrenia, dementia, and other disorders may develop or worsen in isolated confinement.

While expanding cell capacity poses financial and logistical hurdles, many advocate that additional space is vital to protect inmates from these demonstrated physical and psychological effects.

Comparative Cell Sizes Around the World

Prison cell size standards vary greatly across different countries. Population dynamics, resources, cultural views on incarceration, and other factors lead to national differences. Here are some examples:

  • United States – Average cell sizes range from 55-100 square feet in many facilities. Cells tend to be smaller in high security conditions.
  • Canada – Cells average 60-100 square feet across federal prisons. Provincial jails have smaller cells around 40-60 square feet.
  • United Kingdom – The government mandates a minimum cell size of approximately 76 square feet.
  • Australia – Cell area is approximately 88 square feet. Private rooms are provided in many facilities.
  • Scandinavia – Known for more spacious and comfortable cells. Norway provides cells averaging 105 square feet with amenities like televisions and mini-fridges.
  • Russia – Overcrowding is common with instances of only 20 square feet per person in some remote prisons.
  • China – Highly crowded conditions with reports of less than 30 square feet per inmate in some areas.

South America – Many nations like Brazil and Venezuela have huge overcrowding with cell space under 40 square feet per person.

While international standards vary, US cell sizes tend to be on the smaller end, especially for maximum security inmates. Calls persist for increasing minimum cell sizes.

Designing a Humane Prison Cell

If given the chance to design a model prison cell, how could it be shaped to provide humane confinement for inmates? Here are some key features to consider:

  • Minimum size – 80-100 square feet to allow free movement and amenities
  • Natural lighting – Large exterior windows and air circulation
  • Comforts – Bed, desk, stool, shelving, and toilet/sink
  • Privacy – Partition walls or barriers between cellmates
  • Accessibility – Open sight lines and easy mobility
  • Amenities – Television, radio, books, hygiene products
  • Creative outlets – Writing surfaces, art supplies
  • Safety – Direct supervision by officers
  • Door design – Wide access without feeling overly confined

With thoughtful design, even small cells could be optimized for living conditions that protect inmate health and quality of life behind bars.

Understanding the reality of life inside a 6×8 foot prison cell provides perspective on the inmate experience. While expanding cell capacity poses challenges, the debate continues over finding balance between security and humane treatment.


The size of prison cells remains at the center of debates over inmate rights and living standards behind bars. US prisons tend to have smaller cells than in other developed nations, especially in high security facilities. Though cells have improved from their earlier iterations, many still fail minimum space standards advised by corrections experts. Living long-term in such confined spaces has demonstrable impacts on physical and mental health. As overcrowded conditions persist, momentum builds for legal reform and designing cells focused more on rehabilitation. Achieving adequate living space continues to be a struggle amid polarized views on containing or uplifting inmate populations. But re-examining cell sizes remains vital for balancing safety with humanity in the corrections system. Only through evolving our notions of just confinement can we build prisons representing the best of our social values.

Questions Regarding Prison Cell Sizes

What are the typical dimensions of a prison cell?

Typical US prison cells range from 5-7 feet wide by 8-10 feet long, with total square footage of 45-120 square feet depending on the security level. Maximum security cells tend to be the smallest at around 6×8 feet (48 sq ft). Medium security cells average 6×10 feet (60 sq ft). Minimum security cells may be as large as 8×12 feet (96 sq ft). Cell height is usually 6 to 7 feet.

How much space does an inmate have to move around in a prison cell?

The amount of free space for moving around inside a prison cell is very limited. Once beds, desk, toilet and other fixtures are accounted for, maximum security cells may only have 10-15 square feet of open floor space. Inmates are extremely restricted, mostly able to take a few steps pacing across the cell length or get up to use the toilet. Out-of-cell time is crucial for mobility.

What amenities are included in a standard prison cell?

A basic prison cell typically includes a bunk bed, combined toilet/sink, concrete desk and stool, shelves for storage, and sometimes a small window. Cells do not have additional furnishings or amenities beyond these sparse necessities. Some inmates are allowed a small TV or radio if they can afford to purchase one. Personal items like books or hygiene products may also be permitted.

How do small prison cells impact inmate mental health?

Mental health experts warn that confinement in tiny, isolated prison cells can cause psychological damage. Inmates locked in 6×8 or 6×10 foot cells for 23+ hours per day often suffer from anxiety, paranoia, depression, thoughts of self-harm, and psychotic breaks. Lack of environmental stimulation and social interaction contribute to poor mental health behind bars.

What is the minimum cell size recommended for inmates by correctional standards organizations?

The American Correctional Association recommends a minimum size of 70 square feet of floor space for single occupancy cells. Other groups offer similar advice, generally recommending cells in the range of 70-80 square feet at minimum. Critics argue many US prison cells fall well below these standards, especially in maximum security facilities.

How could prison cells be designed to provide more humane conditions?

To design a more humane prison cell, considerations include maximizing natural light, allowing free movement, providing basic comforts like a real bed, ensuring privacy barriers between cellmates, and installing amenities like a television or desk. Maintaining sight lines for safety while limiting claustrophobia is also important. Small details can make long-term confinement less harsh.
