# Lens Magnification Calculator

Below is the online magnification equation calculator based on the image distance (d_{i}) and object distance (d_{o}). The magnification of an object is the ratio of the height of the image (h_{i}) where you can see the height of the actual object is being magnified (h_{o}). The magnification equation is given as M = -(d_{i} / d_{o}). In the below Lens Magnification Calculator, enter the values for the image distance and the object distance to know the magnification of lens(M).

### Example:

Calculate magnification of lens for the image distance and object distance as 29 mm and 25 mm.

#### Magnification Equation Calculation:

M = -(d_{i} / d_{o})

Lens Magnification (M) = -29 / 25

= -1.16 mm
