Sensor Size, Crop Factor & Pixel Pitch
Calculate the crop factor, diagonal, area and pixel pitch of a camera sensor from its width, height and megapixels, free online.
About this calculator
Crop factor = 43.27 mm (full-frame diagonal) ÷ sensor diagonal. Pixel pitch ≈ √(sensor area ÷ number of pixels). Larger pixels collect more light and generally give lower noise; diffraction starts to limit sharpness when the Airy disk exceeds about 2 pixels.
