Hanging pictures is a simple job, but it does require some exact measurements to get the job done right. There is no single formula for hanging pictures as it depends on the picture’s size, weight and the kind of walls you have. However, there are some basic guidelines that can help you hang your picture correctly.
• Measure the size of the picture and the area where you would like to hang it.
• Estimate the weight of the picture, so that you know what kind of wall hook is suitable for the picture.
• Use a hook that is rated to hold five times the weight of the picture.
• Determine the height at which you would like to hang the picture. The general rule of thumb is to hang pictures so that their center is at eye level (about 5 feet from the ground). You can also make a horizontal line as a guideline.
• Using a level, make sure the line or marked spot is straight.
• Secure the hook on the wall and make sure that it is properly attached.
• Hang the picture and make sure that the hook is securely behind the wire.
• After making sure that the hook is safely attached, use a nail to hold the wire in place.
