By the Nest & Yard editorial teamUpdated 2026-08-095 min read

Our pick: the UPVC Door Handles Set - Black - Lever/Lever - 92mm PZ (Centres) - 122mm Screw to Screw - Backplate 212mm X 34mm - UPVC Door Handle - Black Replacement UPVC Door Handles - PVC Door Handle — the best Door Handles & Knobs we tested, from £12.99.

Choosing door handles and knobs for the first time can feel a little overwhelming, with a surprising number of terms and measurements to consider. When you’re starting out, it's really useful to focus on the basic dimensions – particularly the centres (the distance between the spindle holes) and the screw-to-screw measurement – as these are key to ensuring a proper fit. While finishes like polished chrome or brass might be tempting, don’t get bogged down in specific detailing until you have a better understanding of your door's requirements and options such as lever/lever sets or replacement handles are available.

FAQ

What's the difference between a knob and a lever?

Knobs are round handles you turn with your palm, typically used on internal doors. Levers have a shaped head – usually a T-shape – that you push up or down to open the door; they’re often preferred for external doors.

What does 'backplate' mean?

The backplate is the metal piece that attaches to the wall behind the door, providing support and fixing points for the handle. It’s crucial to ensure it fits snugly against the wall and is securely attached using appropriate screws.

Why are different hole spacings important?

Door handles have a specific hole pattern (usually 3 or 4 holes) which must align with the mortise – the recess cut into your door. Incorrect spacing will prevent you from installing the handle correctly.

What material should I choose for my door handles?

Brass is a popular choice for its durability and resistance to tarnishing, but stainless steel is great for exterior doors due to its weather resistance. Consider the environment where the handle will be used when selecting your material.

How do I measure for a new door handle?

Measure the distance between the centre of each hole on your door – this is the ‘hole spacing’. Ensure you get an accurate measurement before ordering, as it's critical for fit.

What does 'mortise cut' refer to?

A mortise cut is the shape and size of the recess in your door where the handle will be fitted. It’s usually a rectangular or square opening depending on the handle design.

Do I need special tools to install a new door handle?

You'll typically need a screwdriver (Phillips head is most common), possibly a small Allen key, and potentially a drill for pilot holes in the wall backplate. Check the manufacturer’s instructions for specific tool requirements.

What if the backplate doesn't fit flush against the wall?

If the backplate isn’t flush, it could compromise the handle’s operation and security. Ensure you are using the correct size screws and that the wall is prepared appropriately (e.g., plasterboard needs fixing to a stud).

Can I install a door handle myself?

Yes, with careful measurement and following instructions, most people can install a basic door handle. However, if you’re unsure or dealing with complex installations, consider seeking professional assistance.

What should I do if the handle feels loose after installation?

Check that all screws are tightened securely. If the issue persists, ensure the backplate is correctly fitted and providing sufficient support; consult the manufacturer's instructions for further troubleshooting.

In depth

Let’s talk about the handles and knobs on your doors – they might seem like small things, but choosing the right ones can make a real difference to how your home feels and looks. If you're new to this, it's perfectly normal to feel a little confused by all the different terms used. Don’t worry; we’ll break it down simply. We're focusing on what really matters when you’re making your first purchase, so you don’t get bogged down in unnecessary details.

Essentially, there are two main types of door handles you’ll encounter: levers and knobs. Levers are the ones with a curved, often rectangular shape that you push up or down to open the door. They're incredibly common on internal doors, like bedrooms or bathrooms, and they’re generally easier for people with limited dexterity to operate – particularly those who might have arthritis or other conditions affecting their hands. Knobs, conversely, are round and turn, typically clockwise to open. You’ll find them most often on external doors, such as front doors and back doors, where a more robust mechanism is needed to withstand the forces of weather and potential misuse. The key difference lies in the action: levers require a pushing motion whereas knobs need a turning one.

Now, let's look at some of the terms you might hear. "Backplate" refers to the metal piece that sits against the wall behind the door – it’s what holds the handle itself in place. It’s important to make sure the backplate is securely fitted; a loose backplate will mean a wobbly, uncomfortable handle. The size of the backplate is important too - some doors have larger spaces and need a bigger backplate. Next, you'll often see “rose” mentioned. This is the decorative centre piece that sits behind the backplate – it adds a touch of style to your door hardware. You can change this out easily if you want to update the look without replacing the entire handle mechanism. Finally, "spindle" refers to the central rod that connects the lever or knob to the backplate and often extends through the door itself. It’s a critical component for how smoothly the handle operates.

When it comes to materials, you'll find handles made from brass, steel, and sometimes even wood or other composites. Brass is a popular choice as it has a classic look and resists tarnishing relatively well. Steel is generally more durable and often used for external doors where they’re exposed to the elements. Consider where your door is located – if it's constantly wet or cold, you might want something particularly robust like steel. For internal doors, appearance is frequently a higher priority, so brass or even painted finishes can be good choices. Don’t worry too much about the specific alloy of metal at this stage; focusing on durability and finish will serve you better.

The ‘action’ of the handle – how smoothly it moves – is another important factor. A well-made lever or knob should feel smooth and responsive, without any sticking or resistance. Give each handle a few tries to check for this before you commit to buying it. You'll notice some are more 'tight' than others; this isn’t necessarily a bad thing, but it does mean they're built to withstand more force. For external doors, a slightly tighter action is preferable – it indicates a stronger mechanism that won’t easily strip or fail under pressure. It’s also worth considering the weight of the handle; heavier handles tend to feel more substantial and reassuring.

Don’t get caught up in complicated finishes like ‘polished chrome’ or ‘brushed nickel’ at this early stage. These are largely aesthetic choices, and while they can look nice, they don't significantly impact the functionality of the handle. A simple brushed brass finish is a safe bet that will complement most interiors. Similarly, the dimensions – things like the width of the backplate or the diameter of the knob – aren’t as critical as you might think. As long as the handle fits reasonably well on your door, it should function correctly. You can always adjust slightly if needed, but it's much easier to start with a standard size.

Finally, remember that you don't need to buy a complete set of handles and knobs for every single door in your home right away. Start with the most important doors – usually the front and back doors – and then add more as needed. It’s far better to get a few good quality handles than a lot of cheap ones. And, crucially, don't feel pressured to spend a fortune. There are plenty of excellent handles available at reasonable prices. Focus on getting something that feels comfortable and works well, and you'll be delighted with your choice. Don’t worry about matching everything perfectly; a slightly different style can add character to your home.
