I want my object to look correct when mounted.  What method of 'leveling' should I use?

As the Keyhole Companion exactly marks the object mounting position with essentially no subsequent adjustment available, it is very important to get the object in exactly the right position prior to marking the fastener locations.

Visual Method of Getting an Object Correctly Positioned

The visual method is preferred by many people as it results in the best visual “look”; it allows for consideration of non-square aspects of walls, ceilings, door frames, moldings, etc., the visual effect of nearby objects, and appropriate height, etc. For example, a perfectly level picture may not look correct if mounted near a door frame that is not perfectly vertical or a ceiling that is not perfectly horizontal. And the look not being correct for that level object becomes greater as the object becomes larger.

Use of Mini-bubble Level

A mini-bubble level is very useful for approximate leveling of objects to me mounted, but typically is not accurate enough for precision leveling. Since the mini-level is small, any slight error in the level itself or how it is attached on the object can result in the object having an incorrect look when mounted. And the look not being correct increases significantly as the object becomes larger. For example, consider a mini-level mounted on a 1-foot wide frame in a way that results in a 1/8” side-to-side slant of the object, which is probably not very perceptible. Now assume the frame is 4-feet wide; the side-to-side slant will now be a very perceptible ½”.

Use of Full-size (large) Level

A full-size level is the preferred leveling device for precision leveling of objects, particularly so if the objects are large. The best leveling accuracy is obtained when the level approaches the same size (width) as the object being mounted.
