Some professional DSLRs, [[Sony SLT camera|SLTs]] and [[mirrorless camera]]s use ''[[full-frame DSLR|full-frame]]'' sensors, equivalent to the size of a frame of 35 mm film.

Most consumer-level DSLRs, SLTs and mirrorless cameras use relatively large sensors, either somewhat under the size of a frame of [[Advanced Photo System|APS]]-C film, with a [[crop factor]] of 1.5–1.6; or 30% smaller than that, with a crop factor of 2.0 (this is the [[Four Thirds System]], adopted by [[OlympusOM System]] (company)formerly [[Olympus Corporation|Olympus]]) and [[Panasonic Corporation|Panasonic]]).

{{As of|2013|11}}, there was only one mirrorless model equipped with a very small sensor, more typical of compact cameras: the [[Pentax Q#Pentax Q7|Pentax Q7]], with a 1/1.7" sensor (4.55 crop factor). See section [[#SensorsImage equippingsensor compactformat#Smaller digital cameras and camera-phonessensors|Sensors equipping Compact digital cameras§ andSmaller camera-phonessensors]] section below.

Many different terms are used in marketing to describe DSLR/SLT/mirrorless sensor formats, including the following:

* {{val|860|u=mm2}} area [[Full-frame digital SLR]] format, with sensor dimensions nearly equal to those of [[135 film|35 mm film]] (36×24 mm) from [[Pentax_K-1|Pentax]], [[Panasonic Corporation|Panasonic]], [[Leica Camera|Leica]], [[Nikon]], [[Canon (company)|Canon]], [[Sony]] and [[Sigma Corporation|Sigma]].

* {{val|370|u=mm2}} area [[APS-C]] standard format from [[Nikon]], [[Pentax]], [[Sony]], [[Fujifilm]], Sigma (crop factor 1.5) (Actualactual APS-C film is bigger, however.)

* {{val|330|u=mm2}} area [[APS-C]] smaller format from [[Canon Inc.|Canon]] (crop factor 1.6)

* {{val|225|u=mm2}} area [[Micro Four Thirds System]] format from Panasonic, OlympusOM System, BlackBlackmagic MagicDesign, and Polaroid (crop factor 2.0)

Obsolescent and out-of-production sensor sizes include:

Line 165:

Most sensors are made for camera phones, compact digital cameras, and bridge cameras. Most image sensors equipping compact cameras have an [[aspect ratio (image)|aspect ratio]] of 4:3. This matches the aspect ratio of the popular [[SVGA]], [[XGA]], and [[SXGA]] display resolutions at the time of the first digital cameras, allowing images to be displayed on usual [[computer monitor|monitor]]s without cropping.

{{As of|2010|12}} most compact digital cameras used small 1/2.3" sensors. Such cameras include Canon PowershotPowerShot SX230 IS, FujiFujifilm Finepix Z90 and Nikon Coolpix S9100. Some older [[digital camera]]s (mostly from 2005–2010) used even smaller 1/2.5" sensors: these include Panasonic Lumix DMC-FS62, Canon PowershotPowerShot SX120 IS, [[Sony Cyber-shot DSC-S700]], and Casio Exilim EX-Z80.

As of 2018 high-end compact cameras using one inch sensors that have nearly four times the area of those equipping common compacts include Canon PowerShot G-series (G3 X to G9 X), Sony DSC -RX100 series, Panasonic Lumix TZ100DC-TZ200 and Panasonic DMC-LX15. Canon has an APS-C sensor on its top model PowerShot G1 X Mark III.

[[File:Sensor sizes area.svg|thumb|400px|right|For many years until Sep. 2011 a gap existed between compact digital and DSLR camera sensor sizes. The x axis is a discrete set of sensor format sizes used in digital cameras, not a linear measurement axis.]] Finally, Sony has the DSC-RX1 and DSC-RX1R cameras in their lineup, which have a full-frame sensor usually only used in professional DSLRs, SLTs and MILCs.
