A '''pictogram''' (also '''pictogramme''', '''pictograph''', or simply '''picto'''<ref>Gove, Philip Babcock. (1993). ''Webster's Third New International Dictionary of the English Language Unabridged''. Merriam-Webster Inc. {{ISBN|0-87779-201-1}}.</ref>) is a graphical [[Symbol|symbol]] that conveys meaning through its visual resemblance to a physical object. Pictograms are used in systems of writing and visual communication. A pictography is a [[Social:Writing system|writing system]]<ref>{{Cite book|last=Goody|first=Jack|title=The interface between the written and the oral|date=1987|isbn=0-521-33268-0|location=Cambridge|page=4|oclc=14242868}}</ref> which uses pictograms. Some pictograms, such as [[GHS hazard pictograms|hazard pictograms]], may be elements of formal languages.

In the field of prehistoric art, the term "pictograph" has a different definition, and specifically refers to art painted on rock surfaces. Pictographs are contrasted with petroglyphs, which are carved or incised.

Small pictograms displayed on a computer screen in order to help the user navigate are called ''[[Icon (computing)|icons]]''.

==Historical==
Early written symbols were based on pictograms (pictures which resemble what they signify) and ideograms (symbols which represent ideas). Ancient Sumerian, Egyptian, and Chinese civilizations began to adapt such symbols to represent concepts, developing them into logographic writing systems. Pictograms are still in use as the main medium of written communication in some non-literate cultures in Africa, the Americas, and Oceania. Pictograms are often used as simple, pictorial, representational symbols by most contemporary cultures.

In 2011, UNESCO's World Heritage List added "Petroglyph Complexes of the Mongolian Altai, Mongolia"<ref>{{cite web|url=https://whc.unesco.org/en/list/1382|title=Petroglyphic Complexes of the Mongolian Altai|publisher=UNESCO World Heritage Centre|website=WHC.UNESCO.org|date=2011}}</ref> to celebrate the importance of the pictograms engraved in rocks.

Some scientists in the field of neuropsychiatry and neuropsychology, such as [[Biography:Mario Christian Meyer|Mario Christian Meyer]], are studying the symbolic meaning of indigenous pictographs and petroglyphs,<ref>{{cite book|url=http://unesdoc.UNESCO.org/images/0006/000678/067843F.pdf|id=ED-85/WS/65|title=Apprentissage de la langue maternelle écrite: étude sur des populations "les moins favorisées" dans une approche interdisciplinaire|first=Mario Christian|last=Meyer|date=December 1985}}</ref> aiming to create new ways of communication between native people and modern scientists to safeguard and valorize their cultural diversity.<ref>{{cite book|title=Amazon Up Close|editor-first=Pamela|editor-last=Bloom|chapter-url=http://www.pisad.bio.br/artigos/amazonupclose_outoftheforest.pdf|archive-url=https://web.archive.org/web/20120317084754/http://www.pisad.bio.br/artigos/amazonupclose_outoftheforest.pdf|archive-date=2012-03-17|chapter=Out Of The Forest & Into The Lab: Amerindian Initiation Into Sacred Science|first=Mario Christian|last=Meyer}}</ref>

== Modern uses ==
An early modern example of the extensive use of pictograms may be seen in the map in the London suburban timetables of the London and North Eastern Railway, 1936–1947, designed by George Dow, in which a variety of pictograms was used to indicate facilities available at or near each station.  Pictograms remain in common use today, serving as pictorial, representational signs, instructions, or statistical diagrams. Because of their graphical nature and fairly realistic style, they are widely used to indicate public toilets, or places such as airports and train stations.  Because they are a concise way to communicate a concept to people who speak many different languages, pictograms have also been used extensively at the Olympics since the 1964 summer games in Tokyo featured designs by {{Interlanguage link|Masaru Katsumi|fr}}. Later Olympic pictograms have been redesigned for each set of games.<ref>{{cite web|url=https://pages.uncc.edu/visualrhetoric/projects/illustration-video/olympic-pictograms/|work=Visual Rhetoric|title=Olympic Pictograms|first1=C.

Pictographic writing as a modernist poetic technique is credited to [[Biography:Ezra Pound|Ezra Pound]], though [[French language|French]] surrealists credit the [[Place:Pacific Northwest|Pacific Northwest]] American Indians of [[Earth:Alaska|Alaska]] who introduced writing, via totem poles, to [[Earth:North America|North America]].<ref>Reed 2003, p. xix</ref>

Contemporary artist Xu Bing created Book from the Ground, a universal language made up of pictograms collected from around the world. A Book from the Ground chat program has been exhibited in museums and galleries internationally.

Emojis are a type of pictogram.

In statistics, pictograms are charts in which icons represent numbers to make it more interesting and easier to understand. A key is often included to indicate what each icon represents. All icons must be of the same size, but a fraction of an icon can be used to show the respective fraction of that amount.<ref>{{cite web|url=http://www.bbc.co.uk/skillswise/factsheet/ma37grap-e3-f-pictograms|title=Understanding pictograms|website=BBC — Skillswise|access-date=2014-05-11|archive-url=https://web.archive.org/web/20131229012040/http://www.bbc.co.uk/skillswise/factsheet/ma37grap-e3-f-pictograms|archive-date=2013-12-29}}</ref>

==In medicine and agriculture==
Miscommunication, for example due to language barriers or cognitive impairment, is a relevant factor for misdiagnosis in medicine. Pictograms and other forms of visual aids have therefore been used to ease communication and improve patient care, for example by ensuring medication adherence.<ref name="DOI10.2146/ajhp060162">Marra G. Katz, Sunil Kripalani, Barry D. Weiss: ''Use of pictorial aids in medication instructions: A review of the literature.'' In: ''American Journal of Health-System Pharmacy.'' 2006, Band 63, Nummer 23, S.&nbsp;2391–2397 {{DOI|10.2146/ajhp060162}}.</ref> Reviews found especially pronounced effects in low-literacy patients.<ref name="DOI10.1016/j.pec.2020.11.034">Njabulo Mbanda, Shakila Dada, Kirsty Bastable, Ingalill Gimbler-Berglund, Schlosser Ralf W.: ''A scoping review of the use of visual aids in health education materials for persons with low-literacy levels.''

There is regular use of pictograms for products used in agriculture to aid hazard recognition, and also to advise on the correct usage of [[Chemistry:Agrochemical|agrochemical]]s for agricultural workers with limited reading skills. This is often a national legal requirement, and many pictograms are standard throughout the industry.<ref>{{cite web|title=FAO: Guidelines on Good Labelling Practice for Pesticides|url=https://www.fao.org/fileadmin/templates/agphome/documents/Pests_Pesticides/Code/Old_guidelines/label.pdf|access-date=4 August 2025}}</ref>

==Standardization==
Pictograms can often transcend languages in that they can communicate to speakers of a number of tongues and language families equally effectively, even if the languages and cultures are completely different. This is why road signs and similar pictographic material are often applied as global standards expected to be understood by nearly all.

A standard set of pictograms was defined in the [[International standard|international standard]] ''[[ISO 7001]]: Public Information Symbols''. Other common sets of pictographs are the laundry symbols used on clothing tags and the [[GHS hazard pictograms|chemical hazard symbols]] as standardized by the GHS system.

Pictograms have been popularized in use on the Internet and in [[Software|software]], better known as "icons" displayed on a computer screen in order to help user navigate a computer system or mobile device.
