Types of Door Latches
Door latches come in various shapes and sizes, and they perform the critical role of keeping doors closed and locked. Before choosing a door latch for your home or office, it is essential to understand the different types available in the market.
- Mortise Latches: These types of latches are housed in a rectangular pocket called a mortise that is cut into the door’s edge. Mortise latches work together with a mortise lock and handle set, and they are typically installed on exterior doors.
- Tubular Latches: These latches have a cylindrical shape and are installed on the door’s edge. Tubular latches work with a doorknob, lever handle, or thumb turn knob and are commonly used on internal doors.
- Rim Latches: These latches are mounted on the door’s surface and are visible on the face of the door. They work with a rim lock and handle set and can be used on both internal and external doors.
Another crucial aspect to consider when selecting a door latch is the latch’s size. Door latches come in standard sizes, and it is crucial to use the appropriate latch size for your door. The standard size for a tubular latch is usually 63mm or 75mm, while the standard size for a mortise latch is usually 63mm or 76mm.
To determine the correct size for your door latch, measure the backset, which is the distance from the door’s edge to the center of the hole where the doorknob or lever handle will be fitted. The backset should match the size of the latch, so it fits perfectly into the door and works correctly.
| Type of Latch | Common Uses | Standard Sizes |
|---|---|---|
| Mortise Latches | Exterior doors, heavy-duty doors | 63mm, 76mm |
| Tubular Latches | Internal doors, light-duty doors | 63mm, 75mm |
| Rim Latches | Internal and external doors, wood and metal doors | 76mm |
Choosing the right door latch for your needs is vital. With different types and sizes available in the market, it is essential to understand the function of each latch and ensure you select the appropriate one for your door.
Standard Door Latch Sizes
Door latches are an essential part of any door, as they keep the door securely closed and prevent it from opening by itself. The size of the door latch is an important factor when it comes to selecting the right latch for your door. In this article, we will discuss the standard door latch sizes.
- The most common door latch size is 2-3/8 inches, which is also known as the backset size. The backset size is the distance from the edge of the door to the center of the latch hole. This size is suitable for most residential and commercial doors.
- Another standard door latch size is 2-3/4 inches. This size is typically used on commercial doors that are thicker than standard residential doors.
- There are also adjustable door latches that can accommodate both 2-3/8 inch and 2-3/4 inch backset sizes.
If you are unsure about the size of your door latch, there are a few ways to measure it. You can measure the backset size by measuring the distance from the edge of the door to the center of the borehole. You can also measure the width of the door latch faceplate, which is usually either 1 inch or 2-1/4 inches.
It is important to ensure that your door latch is the correct size for your door. A door latch that is too small or too big can compromise the security of your door, as it may not fit properly and can be easily forced open.
| Door Latch Size | Backset Size | Faceplate Width |
|---|---|---|
| 2-3/8 inches | 2-3/8 inches | 1 inch or 2-1/4 inches |
| 2-3/4 inches | 2-3/4 inches | 1 inch or 2-1/4 inches |
Overall, choosing the correct size of door latch is an important factor in ensuring the safety and security of your home or business. By understanding the standard door latch sizes, you can make an informed decision when purchasing a door latch.
Factors Affecting Door Latch Sizes
Doors are an essential feature of any building and play a crucial role in securing the premises. The door latch is an integral part of the door assembly as it ensures that the door stays shut and can be locked securely. The size of the door latch is crucial in ensuring its effectiveness, and several factors can affect it.
- Door Material: The material used in the construction of the door can significantly impact the size of the door latch. For instance, solid wood doors are thicker and require longer latches to engage the strike plate, while lightweight doors made of metal or fiberglass need shorter latches.
- Door Thickness: The thickness of the door is another critical aspect that affects the size of the door latch. The standard door thickness is generally 1 3/8 inches to 1 3/4 inches. However, some doors may be thicker or thinner than the standard dimensions, requiring customized door latches.
- Lock Type: The type of lock used on the door also determines the size of the door latch. Deadbolts, for instance, require longer latches, while latchbolts need shorter latches. Electronic locks also require specialized latch sizes to provide optimal security.
Customizing Door Latches
In some cases, standard door latches may not be suitable for specific types of doors or locks. Customized door latches can be the solution in such instances. Manufacturers can customize door latches based on the door’s thickness, lock type, and material to provide the perfect fit.
When ordering customized latches, it is vital to provide the manufacturer with accurate measurements and specifications to ensure the latch fits precisely and functions effectively.
The Standard Size for Door Latches
Although door latch sizes can vary depending on the factors discussed earlier, some standard sizes are widely used in the industry. The table below provides a summary of the standard sizes for door latches.
| Door Thickness (inches) | Latch Length (inches) |
|---|---|
| 1 3/8 | 2 3/8 |
| 1 3/8 | 2 3/4 |
| 1 3/4 | 2 3/8 |
| 1 3/4 | 2 3/4 |
It’s essential to note that the dimensions in the table are the standard sizes, but custom sizes may be required in some instances. Always consult with a door hardware expert to determine the best door latch size for your specific needs.
Door Latch Assembly Process
When it comes to door latches, the assembly process is an important aspect that affects their durability and functionality. Depending on the type and model of the latch, the assembly process may vary. However, here are some of the standard steps involved in the assembly process of door latches:
- Installation of the latch handle: This involves attaching the handle to the latch body using screws or other fasteners. The handle is usually made of metal or plastic and is designed to provide a firm grip for opening and closing the door.
- Insertion of the latch bolt: The latch bolt is a small metal piece that is inserted into the latch body. The bolt is usually spring-loaded and extends or retracts depending on the movement of the latch handle.
- Mounting the strike plate: The strike plate is attached to the door jamb using screws or other fasteners. The latch bolt extends into the strike plate when the door is closed, thereby securing the door in place.
Door latches can be further classified based on the materials used in their assembly. Some door latches feature metal or brass components that are known for their durability and strength. Others may use plastic or composite materials that are more affordable and lightweight.
Here’s a table that summarizes the different types of door latches and their assembly materials:
| Type of Door Latch | Assembly Materials |
|---|---|
| Mortise Latch | Metal, Brass |
| Cylindrical Latch | Metal, Plastic |

Regardless of the assembly materials or process, quality door latches should be able to withstand frequent use and provide secure closure for the doors. As such, it’s advisable to purchase door latches from reputable manufacturers and suppliers who offer durable and reliable products.

In the United States, the most common door size is 36 inches wide by 80 inches tall, and most door latches are designed to fit this size.
