Hey there! If you're in the market for a UPVC multipoint door lock, one of the most common questions you'll have is, "What size UPVC multipoint door lock do I need?" Well, you've come to the right place. As a supplier of UPVC multipoint door locks, I've helped countless customers figure out the perfect size for their doors. In this blog, I'll break down everything you need to know to make an informed decision.
Understanding UPVC Multipoint Door Locks
Before we dive into the sizing, let's quickly go over what UPVC multipoint door locks are. These locks are a popular choice for UPVC doors because they offer enhanced security. Unlike traditional single-point locks, multipoint locks secure the door at multiple points along the edge. This makes it much more difficult for intruders to force the door open.

Factors Affecting the Size of the Lock
Door Thickness
The thickness of your UPVC door is one of the most important factors in determining the size of the multipoint lock you need. Most UPVC doors have a standard thickness, but it can vary. Common door thicknesses range from 40mm to 58mm. You'll need to measure the thickness of your door accurately. You can do this by using a tape measure. Just measure from the inside edge of the door to the outside edge at the point where the lock will be installed.
If your door is on the thinner side (around 40 - 44mm), you'll need a lock that is designed to fit these thinner doors. Thicker doors (50 - 58mm) will require a lock with a longer backset or a different mechanism to ensure a proper fit.
Door Height and Width
The height and width of your door can also play a role in the size of the lock. Larger doors may require a more robust locking system with longer deadbolts or more locking points to provide adequate security. For example, a tall and wide French door may need a multipoint lock with additional deadbolts at the top and bottom to prevent the door from being forced open.
Locking Points
The number of locking points you need depends on your security requirements. Multipoint locks can have anywhere from 2 to 7 or more locking points. The more locking points, the more secure the door. However, more locking points also mean a larger and more complex lock mechanism.
If you live in a high-crime area or want maximum security, you might opt for a lock with 5 or more locking points. For a standard residential door, 3 or 4 locking points may be sufficient.
Measuring for the Right Size
Step 1: Measure the Door Thickness
As mentioned earlier, use a tape measure to measure the thickness of your door. Make sure to measure at the point where the lock will be installed, as the thickness can vary slightly across the door.
Step 2: Check the Existing Lock (if applicable)
If you're replacing an existing lock, check the dimensions of the old lock. This can give you a good starting point for finding the right size replacement. Look at the length of the deadbolts, the backset (the distance from the edge of the door to the center of the keyhole), and the overall size of the lock mechanism.
Step 3: Consider the Door Profile
UPVC doors come in different profiles, which can affect the size and type of lock that will fit. Some doors have a recessed area for the lock, while others have a more flat surface. Make sure to choose a lock that is compatible with your door's profile.
Common Sizes and Compatibility
Standard Sizes
There are some standard sizes for UPVC multipoint door locks that are commonly used. For example, a 26mm backset is a common size for many locks. This means that the center of the keyhole is 26mm from the edge of the door.
However, it's important to note that not all doors will fit these standard sizes. That's why accurate measurement is crucial.
Compatibility with Door Handles
The lock you choose also needs to be compatible with your door handles. Some multipoint locks are designed to work with specific types of handles, such as lever handles or knob handles. Make sure to check the compatibility before making a purchase.
