What is Anthropometrics & Ergonomics?
ANTHROPOMETRICS
• Anthropometrics is the comparative
study of the measurements and
capabilities of the human body.
• Anthropometry has a considerable
importance in optimising the design
of buildings.
• The underlying principle of
anthropometrics is that building
designs should adapt to suit the
human body, rather than people
having to adapt to suit the buildings.
• Ergonomics is the process of
designing or arranging workplaces,
products and systems so that they fit
the people who use them.
• Ergonomics aims to create safe,
comfortable and productive workspaces
by bringing human abilities and limitations
into the design of a workspace, including
the individual’s body size, strength, skill,
speed, sensory abilities (vision, hearing),
and even attitudes.

ANTHROPOMETRY IN
KINDERGARTEN
CLASSROOM AREAS
Ergonomics researchers stressed that children ergonomics is different from adults. Thus, appropriate
furniture design and facilities should be adapted to avoid hazard or injuries to children such as
muscular disorder.
PLAY AREA
Children's playground represents a significant space of activity for pre-school children. Therefore,
it is necessary to apply ergonomic principles which contribute to the adjustment of the
playground elements to children's anatomic features.
WASHROOMS
WC for toddlers/kids – Approx. Width: 315mm & Height: 305mm
Sink top should be 29 inches maximum
DIMENSIONS OF ELEMENTS
THAT ARE CRITICAL IN ANY
EDUCATIONAL SPACES
Dimensions of vital furniture used in schools
CLASSROOMS
Dimensions of Desk & Chair
Dimensions of Bench/Desk & Whiteboard
Middle & High School Classrooms
Children spend more than five hours per day sitting down while doing their school
work. Considering this as well as the potential inadequate use of school furniture, it
is likely that some anatomical functional changes and problems in the learning
process may occur.

AUDITORIUM
• Seating Capacity-
In general the maximum capacity of an auditorium
depends on the format selected. Other factors include
levels, sightlines, circulation & seating density as well
as size & shape of platform/stage.
• Size-
An area of at least 0.5 sq. m per spectator is to be
used for sitting spectators.
• Length of Rows-
A max. of 16 seats per aisles.
• Exit/escape routes-
1m wide per 150 people (min. width 0.8m).
WASHROOMS
• The number of toilets, urinals and
wash-basins required is based on total
number of pupils and separated
according to sex, should be as set out
in the local school buildings
guidelines.
• Sanitary installations with direct
daylight and ventilation are preferable.
• Horizontal and vertical circulations
usually doubles as an emergency
escape routes. Escape routes must
have clear with of minimum width
1M/150 people.
CORRIDORS AND STAIRCASES
A minimum width of 1,200 mm, and 1,000 mm between handrails and rise of steps is 150 – 180mm.
SPORTS
• Children are at risk for sports injuries because their
bodies are still growing and their coordination is still
developing. Many children ages 14 and under are
treated for sports-related injuries each year. Half of all
of those injuries can be prevented with proper use of
safety gear, changes to the playing environment, and
by following sports rules that help prevent injuries.
• There is a wide range of ideal body shapes and
compositions, depending on the sports, the playing
position and the fitness level.
Anthropometry, Ramp size, Toilets of Specially Abled
• Maximum slope for hand-propelled wheelchair
ramps should be 1" of rise to every 12" of length
(4.8 degree angle; 8.3% grade).
• Minimum width should be 36" (inside rails)
- (48" is ideal).
The importance of
ergonomics in schools
School furniture and school children’s sitting posture
• Being the workplace of future workers,
classrooms must be equipped with
furniture that safeguards the physical
wellbeing of pupils through appropriate
ergonomics and the ability to adjust to
their individual physical needs.
• Considering the amount of time school
children spend in school, primarily sitting,
classroom furniture has a crucial role in the
maintenance of good sitting posture and
should be designed to promote it.
• It can be noticed; the importance and benefits
of ergonomics application to improve the
process of education and training.
• Correctly designed classroom furniture is, among
others, one of the most important key factors in
regular development of all abilities of school
children.

Anthropometrics and Ergonomics in Educational Spaces

  • 2. What is Anthropometrics & Ergonomics? ANTHROPOMETRICS • Anthropometrics is the comparative study of the measurements and capabilities of the human body. • Anthropometry has a considerable importance in optimising the design of buildings. • The underlying principle of anthropometrics is that building designs should adapt to suit the human body, rather than people having to adapt to suit the buildings. • Ergonomics is the process of designing or arranging workplaces, products and systems so that they fit the people who use them. • Ergonomics aims to create safe, comfortable and productive workspaces by bringing human abilities and limitations into the design of a workspace, including the individual’s body size, strength, skill, speed, sensory abilities (vision, hearing), and even attitudes. ERGONOMICS

  • 7. CLASSROOM AREAS Ergonomics researchers stressed that children ergonomics is different from adults. Thus, appropriate furniture design and facilities should be adapted to avoid hazard or injuries to children such as muscular disorder.
  • 8. PLAY AREA Children's playground represents a significant space of activity for pre-school children. Therefore, it is necessary to apply ergonomic principles which contribute to the adjustment of the playground elements to children's anatomic features.
  • 9. WASHROOMS WC for toddlers/kids – Approx. Width: 315mm & Height: 305mm Sink top should be 29 inches maximum
  • 10. DIMENSIONS OF ELEMENTS THAT ARE CRITICAL IN ANY EDUCATIONAL SPACES Dimensions of vital furniture used in schools
  • 13. Dimensions of Bench/Desk & Whiteboard
  • 14. Middle & High School Classrooms Children spend more than five hours per day sitting down while doing their school work. Considering this as well as the potential inadequate use of school furniture, it is likely that some anatomical functional changes and problems in the learning process may occur.

  • 19. AUDITORIUM • Seating Capacity- In general the maximum capacity of an auditorium depends on the format selected. Other factors include levels, sightlines, circulation & seating density as well as size & shape of platform/stage. • Size- An area of at least 0.5 sq. m per spectator is to be used for sitting spectators. • Length of Rows- A max. of 16 seats per aisles. • Exit/escape routes- 1m wide per 150 people (min. width 0.8m).
  • 20. WASHROOMS • The number of toilets, urinals and wash-basins required is based on total number of pupils and separated according to sex, should be as set out in the local school buildings guidelines. • Sanitary installations with direct daylight and ventilation are preferable. • Horizontal and vertical circulations usually doubles as an emergency escape routes. Escape routes must have clear with of minimum width 1M/150 people.
  • 21. CORRIDORS AND STAIRCASES A minimum width of 1,200 mm, and 1,000 mm between handrails and rise of steps is 150 – 180mm.
  • 22. SPORTS • Children are at risk for sports injuries because their bodies are still growing and their coordination is still developing. Many children ages 14 and under are treated for sports-related injuries each year. Half of all of those injuries can be prevented with proper use of safety gear, changes to the playing environment, and by following sports rules that help prevent injuries. • There is a wide range of ideal body shapes and compositions, depending on the sports, the playing position and the fitness level.
  • 23. Anthropometry, Ramp size, Toilets of Specially Abled • Maximum slope for hand-propelled wheelchair ramps should be 1" of rise to every 12" of length (4.8 degree angle; 8.3% grade). • Minimum width should be 36" (inside rails) - (48" is ideal).
  • 24. The importance of ergonomics in schools School furniture and school children’s sitting posture
  • 25. • Being the workplace of future workers, classrooms must be equipped with furniture that safeguards the physical wellbeing of pupils through appropriate ergonomics and the ability to adjust to their individual physical needs. • Considering the amount of time school children spend in school, primarily sitting, classroom furniture has a crucial role in the maintenance of good sitting posture and should be designed to promote it. • It can be noticed; the importance and benefits of ergonomics application to improve the process of education and training. • Correctly designed classroom furniture is, among others, one of the most important key factors in regular development of all abilities of school children.
