The standard door lock size varies with the style and design of the door. Since doors are not equal, you expect their lock holes to be different. Therefore, when you make your choice, you would want to know the details of the door including the size of the hole.

Standard Door Lock Hole Size - Types of Features
When it comes to door handles and locks, there are many different types to choose from. Now that you are here, this post will be exploring the hole size for standard doors. It will categorize the doors in clusters and breakdown their features.

Standard Door Latches
Working on drive-in door latches is an easy task. When following locksmith tricks and tips, installation will not take you a long time. All you need is a cross bore whose diameter is 1 inch on one edge of the door. Once the latch is in place, you slide it into the cross bore and drive it in place using a hammer or mallet. Once in place, the ridges will keep it intact and secure.

Standard Door Lever/knob and Deadbolt Lever
When changing locks, this kind of door uses a combination of a deadbolt and a knob. It, therefore, uses two pairs of cross bores and bore holes placed in the same vertical line and 5.5 inches from one center to the other. The cross bore diameter is 1 inch while the bore hole diameter is 2 1/8 inches. Typically, these doors do not use a drive-in latch, but they have square and circular corners for faceplate latches. Using uniform latches on the exterior gives your door an appealing look. Such does not, however, take away its functionality.

Standard Door Lever and Knob Handle
The doors in this category come with one bore hole. The hole has a larger diameter because it is the one that houses the doorknob. Generally, the largest diameter for the bore hole is 2 1/8 inches. There is also a cross bore with 1 inch in diameter and stretches from the edge of the door and runs over the bore hole. It is in the bore hole where the latch fits in. You should also know that these doors can be prepared for 3 different types of latches and leave it to your preference.

Square-corner Faceplate Latches
At times, you will get a door inclined to drive-in latches. What if you want some faceplate latches on your door? That is where square-corner faceplate latches come in. Use a one-inch chisel to scoop out 1/8 of the door material in an area with a diameter of 1 inch and a height of 2 ¼ inches.

Round-corner Faceplate Latches
Look around, and you will notice that round-corner faceplate latches are very common. There is a good reason for that. The latch is held securely in its place, and the faceplate adds an aesthetic value to your door. The dimensions of faceplate latches are 2 ¼ inches for height, 1 inch for width, and ¼ inch diameter at the corners. If this door is for a shop, a router jig is used to prepare it for the faceplate latches.

Bottom Line
There are various door locking mechanisms you can work with. Before you make a decision, ensure you understand the standard door lock hole size. The rest will be chosen according to your preferences. You can also seek the help of a locksmith if you are unsure of your lock hole size.
