The introduction of [[lancet window]]s into Western European [[church architecture]] from the 12th century CE built on a tradition of arched windows <ref>{{cite CE1913|wstitle=Windows in Church Architecture |volume= 15 |last= Kleinschmidt |first= Beda Julius |short=1 |quote= In general two or three windows united in a group, as was later the rule in Roman architecture, were even then of frequent occurrence in the early Christian architecture of Asia Minor. The form of the window is nearly everywhere the same; a rectangle that usually has a rounded top, but seldom a straight lintel.}}</ref> inserted between columns,<ref>{{cite CE1913|wstitle=Windows in Church Architecture |volume= 15 |last= Kleinschmidt |first= Beda Julius |short=1 | quote = The place of the window was determined by the architectural membering of the basilica, the distance between two columns generally indicating the position of a window.}}</ref> and led not only to [[tracery]] and elaborate [[Medieval stained glass|stained-glass]] windows but also to a long-standing motif of pointed or rounded window-shapes in ecclesiastical buildings, still seen in many churches today.

Peter Smith discusses overall trends in early-modern rural Welsh window architecture:
<blockquote>
Up to about 1680 windows tended to be horizontal in proportion, a shape suitable for lighting the low-ceilinged rooms that had resulted from the insertion of the upper floor into the hall-house. After that date vertically proportioned windows came into fashion, partly at least as a response to the Renaissance taste for the high ceiling. Since 1914 the wheel has come full circle and a horizontally proportioned window is again favoured.<ref>

Many [[Modernity|modern day]] windows may have a [[window screen]] or mesh, often made of [[Aluminium|aluminum]] or [[Fiberglass|fibreglass]], to keep [[Bug (insect)|bugs]] out when the window is opened. Windows are primarily designed to facilitate a vital connection with the outdoors, offering those within the confines of the building visual access to the everchanging events occurring outside. The provision of this connection serves as an integral safeguard for the health and well-being of those inhabiting buildings, lest they experience the detrimental effects of enclosed buildings devoid of windows. Among the myriad criteria for the design of windows, several pivotal criteria have emerged in daylight standards: location, time, weather, nature, and people. Of these criteria, windows that are designed to provide views of [[nature]] are considered to be the most important by people.<ref>{{cite journal |last1=Kent |first1=Michael |last2=Schiavon |first2=Stefano |date=2022 |title=Predicting Window View Preferences Using the Environmental Information Criteria |url=https://escholarship.org/content/qt7rv6936v/qt7rv6936v.pdf?t=rgtbft |journal=LEUKOS |volume=19 |issue=2 |pages=190–209 |doi=10.1080/15502724.2022.2077753 |s2cid=251121476 |access-date=2022-11-09}}</ref>
