This is the actual sensor size of Nikon Coolpix L330.
(Note: on some systems the presentation might not be 100% accurate. If in doubt, take a ruler and measure it. It should be 6.16 x 4.62 mm)
The sensor has a surface area of 28.5 mm². There are approx. 20,200,000 photosites (pixels) on this area. Pixel pitch, which is a measure of the distance between pixels, is 1.19 µm. Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next.

Pixel or photosite area is 1.42 µm². The larger the photosite, the more light it can capture and the more information can be recorded.

Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor. Nikon Coolpix L330 has a pixel density of 70.79 MP/cm².

These numbers are important in terms of assessing the overall quality of a digital camera. Generally, the bigger the sensor, pixel pitch and photosite area, and the smaller the pixel density, the better the camera.

The diagonal of Nikon Coolpix L330 image sensor is not 1/2.3 inch as you might expect, but approximately two thirds of that value - 0.3 inch. If you want to know why, see sensor sizes.

Diagonal is calculated by the use of Pythagorean theorem:
Diagonal =  w² + h²
where w = sensor width and h = sensor height

Nikon Coolpix L330 diagonal

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.

Width = 6.16 mm
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

Nikon Coolpix L330 pixel pitch

Sensor width = 6.16 mm
Sensor resolution width = 5183 pixels
Pixel pitch =   6.16  × 1000  = 1.19 µm

Pixel area

The area of one pixel can be calculated by simply squaring the pixel pitch:
Pixel area = pixel pitch²

You could also divide sensor surface area with effective megapixels:
Pixel area =   sensor surface area in mm²
effective megapixels

Nikon Coolpix L330 pixel area

Pixel pitch = 1.19 µm

Pixel area = 1.19² = 1.42 µm²

Pixel density

Pixel density can be calculated with the following 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

Nikon Coolpix L330 pixel density

Sensor resolution width = 5183 pixels
Sensor width = 0.616 cm

Pixel density = (5183 / 0.616)² / 1000000 = 70.79 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:
(X × r) × X = effective megapixels × 1000000    →   
X =  effective megapixels × 1000000
3. To get sensor resolution we then multiply X with the corresponding ratio:

Resolution horizontal: X × r
Resolution vertical: X

Nikon Coolpix L330 sensor resolution

Sensor width = 6.16 mm
Sensor height = 4.62 mm
Effective megapixels = 20.20
r = 6.16/4.62 = 1.33
X =  20.20 × 1000000  = 3897
Resolution horizontal: X × r = 3897 × 1.33 = 5183
Resolution vertical: X = 3897

Sensor resolution = 5183 x 3897

Crop factor

Crop factor or focal length multiplier is calculated by dividing the diagonal of 35 mm film (43.27 mm) with the diagonal of the sensor.
Crop factor =   43.27 mm
sensor diagonal in mm

Nikon Coolpix L330 crop factor

Sensor diagonal in mm = 7.70 mm
Crop factor =   43.27  = 5.62

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).

Nikon Coolpix L330 equivalent aperture

Crop factor = 5.62
Aperture = f3.1 - f5.9

35-mm equivalent aperture = (f3.1 - f5.9) × 5.62 = f17.4 - f33.2
