After all, an incorrectly measured handle can lead to unsatisfactory performance and wastage of time as well as  money. To ensure this does not happen, it's important for us to know how to correctly measure a uPVC door handle before we purchase one.

With this guide, you will be able to measure areas such as length and width, backplate size, screw holes, and more! Read on to find out how to measure uPVC door handles like an expert!

Types of uPVC Door Handles

uPVC door handles come in a variety of shapes and styles to suit any individual décor. Some of the most popular uPVC door handles include Lever/Lever designs, Lever/Pad designs, Handles with Snib, and many more. Let us check them out.

  • Lever/Lever

Lever/Lever uPVC door handles are an ideal solution for any home as they offer a modern and stylish aesthetic while also ensuring convenience and security. They consist of two movable inline handles. Two handles design means that each individual handle features its own spindle, allowing them to function independently from one another, which opens up the possibility of having different functions on either side of the door.

  • Lever/Pad

Lever/Pad handles are made up of a lever handle and a pad handle. The pad handle can be either fixed or movable. These handles help to provide enhanced security with robust anti-snap protection. The handles have been designed to operate with modern Euro cylinders, making them incredibly easy to use as well as aesthetically pleasing. They also feature an adjustable backplate in order to fit any door thickness which is an excellent choice for most uPVC doors.

  • Handles with Snib

Handles with Snib features a thumb-turn attached to a snib which when set (either in upward or downward position), locks the door from being opened. With the snib feature, these handles allow for foolproof locking and unlocking without needing a key. The snib is a locking mechanism that is internal to the handle; when engaged the door can only be locked from the inside. 

Steps on How to Measure uPVC Door Handles

Before purchasing a new uPVC door handle, you will need to take two measurements to ensure that the measurements are accurate. Check out the below mentioned steps to measure uPVC door handles.

  • Top Screw Below uPVC Door Handles

Start by measuring the distance between the latch plate and the centre point of the spindle, as this is where you will need to place your screw on the top section. Measure directly up from the centre point of where you plan to install your handle, then move your tape measure 11 inches down. The lower point is where the centre of the top screw should be placed.

  • Top Screw Above uPVC Door Handles

To measure the top screw above uPVC door handles, you will require only two measurements - the PZ measurement and the Backplate Fixing centres.

  • Measuring the PZ Centres

To measure the centre positions, also known as PZ centres, start by measuring from one edge of the door faceplate to the centre of the key hole and note down this measurement as "A". Then measure from the other edge of the door faceplate across to the PZ centre point and record as "B". The PZ centres can then be calculated using a formula: (A+B)/2 = PZ Centres.

  • Measuring the Backplate Fixing Centres

To measure the backplate fixing centres of your uPVC door handles start by measuring the distance between the two fixing holes on the backplate of your handle, typically centre-to-centre for both top and bottom holes. Note down the total width of the handle at this point and use these measurements to compare products with similar dimensions when shopping for a replacement handle.
Take these measurements and ensure they match what new handles you plan to purchase in order to get a perfect fit. Following these steps will help you choose replacement uPVC door handles that perfectly suit your needs and provide strain free functionality for years to come!


Measuring a uPVC door handle is an important step in ensuring you buy the correct size and shape handle, as well as giving you confidence that it will fit into the standard frame. With proper measurements and reasonable care when fitting, you can replace your old handle with ease, while also solving any potential problems that may arise. If you wish to purchase quality door handles online, Emerald Doors have a wide variety of options for you to select from. Additionally, we provide good-quality internal doors and external doors that you can get at a reasonable price!

FAQs on Measuring uPVC Door Handles

  • How do I know what size door handle I need?

To figure out what size door handle you need, you have to take into consideration the type of latch that will be used with the door handle. If a mortise lock is being used, then you'll need a back set measuring that ranges between 2.75” and 5”. If a cylindrical lock is being used, then add 3/4" to 1-1/2" to your measurement when purchasing a door handle.

  • What size is a standard uPVC door handle?

uPVC door handles come in a range of sizes designed to suit different door designs. The standard size for an uPVC door handle when measured from the centre of the first spindle hole is 92mm or 66p; or 8mm backplate when measured from one screw hole to another across the diagonal of the backplate.

  • Can you replace the handle on a uPVC door?

Replacing the handle on a uPVC door can be a simple task or a more complex one, depending on the existing lockset. If there is an existing euro profile cylinder lock, you will need to unscrew the handle and remove it from the profiles of the door leaf before installing the new one in its place. However, if there's no cylinder lock in place, you'll need to install one first and then go ahead with replacing the handles.

  • How do you measure a new uPVC door lock?

First of all, you'll need to measure the length of the backset – this is the distance between the edge of the door and the centre line of your current lock. After that, you must measure the distance from the latch front faceplate to the centre spot as well as the height and width of the handle.

  • How do you adjust a uPVC door handle?

To adjust the handle, start by removing the two screws that hold it in place on the door frame, using either a screwdriver or hex wrench. Once unscrewed, you should be able to adjust the handle away from or closer to the centre of the handle frame to ensure that it is properly aligned - this will allow the mechanism to work optimally and lock securely.
