How High Should A Deadbolt Be On A Door?

Deadbolts are a popular addition to any entrance door, providing added security due to their design and durability. If you plan to install one of these deadbolts on your door, you may be wondering how to measure where it should go. For your convenience, we have carefully studied the height of the latch on the door.

Unlike standard locks on door handles, where the latch sits on the latch plate of the door frame, Deadbolts have a stronger locking mechanism, making them ideal for exterior doors on your property.

When installing a latch on a door, it is important to consider how far it will be from any existing handles and the bottom of the door frame. The latch and the door handle should remain approximately 6 inches apart. The bolt should normally be approximately 34 to 48 inches from the bottom of the door frame. However, it is best to consult your local building code before installing a deadbolt. Local building codes will indicate the recommended door handle height, which is critical for latch installation. If the latch is installed at a higher height, the structure of the door may be compromised. Installing the latch near the doorknob will provide maximum protection against kick-in attempts. However, installing the bolt too close to the door handle can also affect its practicality.

Are All Doorknobs the Same Height?

Since the doorknob determines the height of the bolt, it is important to understand the height difference. Building codes allow you the freedom to install doorknobs within 34 to 48 inches of the house floor.

However, the most common height for building contractors is about 36 inches, which is the most convenient height for people. Doorknob height is also important for accessibility and meeting ADA codes. 

There are situations that affect the height of door handles, such as people who use wheelchairs. Lowering the door handle will greatly improve accessibility for the occupants of the home.

Step-by-step Guide

• Place the latch plate around the latch hole and trace around the edge.

• Use a chisel to cut away excess wood until the board is flush with the door.
