A plane mirror does not change the size of the (virtual) image reflected from it. Therefore, the magnification is 1.
To determine the magnification of a mirror, divide the height of the image by the height of the object. The result will be the magnification factor.
D(power)=1\f ;f=infinity D=0 for plane mirror
To test mirror magnification, you can place a ruler at a known distance from the mirror and measure the size of the reflected image. By comparing the size of the image to the actual size on the ruler, you can determine the magnification factor of the mirror.
The magnification equation for a convex mirror is given by: M = -1 / (1 - d/f), where M is the magnification, d is the object distance, and f is the focal length of the mirror. The negative sign indicates that the image formed is virtual and upright.
The magnification equation for a concave mirror is given by the formula: M = - (image distance) / (object distance), where M is the magnification, image distance is the distance from the mirror to the image, and object distance is the distance from the mirror to the object. Negative magnification indicates an inverted image.

Plane mirrors have a flat, smooth surface, which produces virtual upright images that are the same size as the object. They obey the law of reflection, where the angle of incidence is equal to the angle of reflection. They do not produce any magnification or distortion of the reflected image.
A plane mirror.
The nature of the image that a spherical mirror produces positive magnification is usually enlarged when compared to the real object.
A plane mirror is a mirror which is completely flat, easier for your image to be reflected.

Sears has an 8" replacement 5x magnification mirror on their web site
3x magnification is a good start, but you really must have a lighted mirror, otherwise it could be a tedious exercise.
