Sensor size comparison
Sensor size is generally a good indicator of the quality of the camera.
Sensors can vary greatly in size. As a general rule, the bigger the
sensor, the better the image quality.
Bigger sensors are more effective, because they have more surface area to capture light. An important factor when comparing digital cameras is also camera generation. Generally, newer sensors will outperform the older. Learn more about sensor sizes » 
Actual sensor sizes:
Surface area:
Fujifilm XS1 has approx. 104% more surface area than Panasonic Lumix DMCFZ200.


Pixel pitch

2.2 µm  1.54 µm  
Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next.
It tells you how close the pixels are to each other.
The bigger the pixel pitch, the further apart they are and the bigger each pixel is. Bigger pixels tend to have better signal to noise ratio and greater dynamic range. 
Pixel pitch
Pixel pitch of Fujifilm XS1 is approx. 43% higher than pixel pitch of Panasonic Lumix DMCFZ200.


Pixel area

4.84 µm²  2.37 µm²  
Pixel or photosite area affects how much light per pixel can be gathered.
The larger it is the more light can be collected by a single pixel.
Larger pixels have the potential to collect more photons, resulting in greater dynamic range, while smaller pixels provide higher resolutions (more detail) for a given sensor size. 
Relative pixel sizes:
A pixel on Fujifilm XS1 sensor is approx. 104% bigger than a pixel on Panasonic Lumix DMCFZ200.


Pixel density

20.61 MP/cm²  42.4 MP/cm²  
Pixel density tells you how many million pixels fit or would fit in one
square cm of the sensor.
Higher pixel density means smaller pixels and lower pixel density means larger pixels. 
Pixel density
Panasonic Lumix DMCFZ200 has approx. 106% higher pixel density than Fujifilm XS1.

Diagonal
Diagonal is calculated by the use of Pythagorean theorem:
where w = sensor width and h = sensor height
Diagonal = √  w² + h² 
Fujifilm XS1 diagonal
The diagonal of Fujifilm XS1 image
sensor is not 2/3 inch as you might expect, but approximately two thirds of
that value. If you want to know why, see
sensor sizes.
w = 8.80 mm
h = 6.60 mm
w = 8.80 mm
h = 6.60 mm
Diagonal = √  8.80² + 6.60²  = 11.00 mm 
Panasonic Lumix DMCFZ200 diagonal

h = 4.62 mm
w = 6.16 mm
h = 4.62 mm
Diagonal = √  6.16² + 4.62²  = 7.70 mm 
Surface area
Surface area is calculated by multiplying the width and the height of a sensor.
Fujifilm XS1 surface area
Width = 8.80 mm
Height = 6.60 mm
Surface area = 8.80 × 6.60 = 58.08 mm²
Height = 6.60 mm
Surface area = 8.80 × 6.60 = 58.08 mm²
Panasonic Lumix DMCFZ200 surface area
Width = 6.16 mm
Height = 4.62 mm
Surface area = 6.16 × 4.62 = 28.46 mm²
Height = 4.62 mm
Surface area = 6.16 × 4.62 = 28.46 mm²
Pixel pitch
Pixel pitch is the distance from the center of one pixel to the center of the
next measured in micrometers (µm). It can be calculated with the following formula:
Pixel pitch =  sensor width in mm  × 1000 
sensor resolution width in pixels 
Fujifilm XS1 pixel pitch
Sensor width = 8.80 mm
Sensor resolution width = 3995 pixels
Sensor resolution width = 3995 pixels
Pixel pitch =  8.80  × 1000  = 2.2 µm

Sensor resolution width = 4011 pixels
Pixel pitch =  6.16  × 1000  = 1.54 µm

Pixel area
The area of one pixel can be calculated by simply squaring the pixel pitch:
You could also divide sensor surface area with effective megapixels:
Pixel area = pixel pitch²
You could also divide sensor surface area with effective megapixels:
Pixel area =  sensor surface area in mm²

Pixel pitch = 1.54 µm
Pixel area = 1.54² = 2.37 µm²
Pixel area = 1.54² = 2.37 µm²
Pixel density
Pixel density can be calculated with the following formula:
You could also use this formula:
Pixel density = (  sensor resolution width in pixels  )² / 1000000 
sensor width in cm 
You could also use this formula:
Pixel density =  effective megapixels × 1000000  / 10000 
sensor surface area in mm² 
Fujifilm XS1 pixel density
Sensor resolution width = 3995 pixels
Sensor width = 0.88 cm
Pixel density = (3995 / 0.88)² / 1000000 = 20.61 MP/cm²
Sensor width = 0.88 cm
Pixel density = (3995 / 0.88)² / 1000000 = 20.61 MP/cm²

Sensor width = 0.616 cm
Pixel density = (4011 / 0.616)² / 1000000 = 42.4 MP/cm²
Sensor resolution
Sensor resolution is calculated from sensor size and effective megapixels. It's slightly higher
than maximum (not interpolated) image resolution which is usually stated on camera specifications.
Sensor resolution is used in pixel pitch, pixel area, and pixel density formula.
For sake of simplicity, we're going to calculate it in 3 stages.
1. First we need to find the ratio between horizontal and vertical length by dividing the former with the latter (aspect ratio). It's usually 1.33 (4:3) or 1.5 (3:2), but not always. 22.8 × 15.5 sensor for example has a ratio of 1.47.
2. With the ratio (r) known we can calculate the X from the formula below, where X is a vertical number of pixels:
3. To get sensor resolution we then multiply X with the corresponding ratio:
Resolution horizontal: X × r
Resolution vertical: X

35 mm equivalent aperture
Equivalent aperture (in 135 film terms) is calculated by multiplying lens aperture
with crop factor (a.k.a. focal length multiplier).
Fujifilm XS1 equivalent aperture
Crop factor = 3.93
Aperture = f2.8  f5.6
35mm equivalent aperture = (f2.8  f5.6) × 3.93 = f11  f22
Aperture = f2.8  f5.6
35mm equivalent aperture = (f2.8  f5.6) × 3.93 = f11  f22
