Actually, the rule of thumb is to align your eyes (straight ahead) to about 3/4 up the height of viewable area of the screen. That is, about 1/4 of the screen is above eye-level, the rest is below and this should apply to any reasonable screen size.
The other way to tell is to press F3 to bring up a messy screen of debug information, including your x,y and z coordinates. y is your height; the game reports both the level of your feet and your eye level, so if you are standing on top of layer 4 your feet will be at level 5 and your eye level will be 6.6.
