How to read the chart

A camera's field of view, depth of field and lens coverage all depend on the area it records, and that changes with the recording mode. This chart lists that area for each published mode, so you can put the real numbers into a field of view, focal length match or depth of field calculation rather than a format name like "Super 35" or "full frame".

Photosites are the sensor pixels the mode reads. Some modes record a different resolution from the same area (a UHD file scaled from a larger readout, for example), so the file size is not always the photosite count.
Width × height is the recorded area as the maker publishes it. This is the number to use for angle of view and crop factor.
Diagonal is worked out from the width and height. Compare it with a lens's stated image circle to see whether the lens covers the mode.
Crop (width) is 36mm divided by the recorded width: the factor to divide a full-frame focal length by for the same horizontal view. The crop factor guide explains why width is the one to match on.

ARRI

ARRI publishes the active image area of every sensor mode on each camera's Technical Data page, and to two decimal places in its Formats and Resolutions Overview, which the figures here follow. ARRI calls the diagonal the image circle.

RED

RED's product pages give the full sensor size; the per-format sizes come from the "All Formats" tables in each camera's operation guide, which RED describes as close approximations. Each format has a family of aspect ratios; the main ones are listed here.

V-RAPTOR [X], V-RAPTOR XL [X] and V-RAPTOR XE (8K VV)

All three use an 8K VV global-shutter sensor, 40.96 × 21.60mm, and their operation guides list the same formats row for row.

FX2, FX3A and FX30

Sony gives only the whole sensor for these cameras, not the area of each movie mode, and Super 35 / APS-C crop and high-frame-rate crop sizes are not published. The FX6 spec gives no sensor size in millimeters at all.

Canon

Canon publishes the effective sensor area, with its diagonal, for the full-frame or Super 35 readout of each Cinema EOS camera, to one decimal place. Its Super 35 and Super 16 crop modes are given only as photosite counts, so they are noted under each table rather than sized.

EOS C400 and EOS C80

The same full-frame 6K sensor. The C400 also records a full-frame 3:2 open gate (6000 × 4000 RAW, from firmware 1.0.4.1), for which Canon does not publish a size.

Panasonic

Panasonic publishes only the whole sensor size. Each video mode is tagged FULL, Super 35 / APS-C or PIXEL/PIXEL (one sensor pixel per video pixel), but the area of each mode is not given in millimeters, so only the sensors are listed here.

LUMIX S1RII, S5IIX, S1H, BS1H, GH7 and BGH1

Whole sensor as published. S1II and S1IIE are left out: Panasonic UK gives 35.8mm wide, the manuals and panasonic.jp 35.6mm.

Questions

What size is a Super 35 sensor?

There is no single size. The full-width Super 35 modes in this chart run from about 22.6mm to 28mm wide: 22.6mm for the VENICE 2 5.4K 16:9 crop, 24.0mm for BURANO's S35 5.8K modes, 26.2mm for the Canon C70 and C300 Mark III in DCI 4K, and 27.99mm for the ALEXA 35 Xtreme's open gate. The 35mm film camera gate is 24.89 × 18.66mm.

How big is a full-frame cinema sensor?

Close to 36 × 24mm, but each maker's differs slightly and most modes record less height. The VENICE 2 8.6K 3:2 mode is 35.9 × 24.0mm and the Canon EOS C50's open gate 35.9 × 23.9mm, while 17:9 modes such as the Canon C400's 6K record 36.0 × 19.0mm. ARRI's large-format open gate is bigger, 36.70 × 25.54mm.

Which camera in the chart has the biggest sensor?

The ARRI ALEXA 265: its 6.5K open gate records 54.12 × 25.58mm, a 59.86mm diagonal. Next is the Blackmagic URSA Cine 17K 65 at 50.81 × 23.32mm in 17K open gate. Both are 65mm formats.

Why does the crop factor change between recording modes?

Because each mode reads a different part of the sensor. On the ALEXA Mini LF, the UHD mode records 31.68mm across instead of the open gate's 36.70mm, a 1.16× crop that makes every lens frame tighter.

Why do some cameras have no per-mode sizes here?

Because the maker does not publish them. Panasonic gives only the whole sensor size, Canon lists its Super 35 and Super 16 crop modes by photosite count only, and Sony gives no per-mode sizes for its FX cameras. The chart lists only figures the maker publishes.

Using the numbers

Put a mode's width and height into CineMath's Field of View calculator to get its angles and frame size at any distance, or its width into Focal Length Match to carry a lens choice from one camera or mode to another. The field of view guide explains the formulas, and open gate vs 16:9 vs anamorphic shows how much each kind of mode change moves the frame. Both calculators are free in your browser too: the field of view calculator and the focal length match calculator.

For depth of field, the circle of confusion scales with the recorded area too: the usual rule of thumb is the diagonal divided by 1,500, as set out in the Cinema Calculations Handbook. The circle of confusion guide lists the usual value by format.
