What is door hardware?

Door hardware is the collective name for all parts you need to operate a door and finish it neatly. Think of door handles, door pulls, rosettes, backplates and matching accessories. Good door hardware balances ease of use with design and is available for different applications, such as interior doors, exterior doors and sliding doors.

Step 1: Choose the right door hardware

Pick the right type of door hardware

• Door handles: The most common option for interior doors, typically mounted on a rosette or a backplate.
• Door pulls: A smart choice for heavier doors, high-traffic spaces or a more contemporary look.
• Door hardware set: Convenient if you want a consistent style throughout your home or project.

Match your choice to your interior

Modern door hardware is popular in clean, minimal interiors and is often finished in black or stainless steel. In warmer or more classic interiors, brass or brushed steel tends to work particularly well. If you want a calm, cohesive look, it’s usually best to stick to the same design across multiple doors—this makes your interior feel more intentional and visually consistent.

Step 2: Check sizing before you buy

Correct sizing prevents frustration during installation. Always verify the key measurements before ordering door hardware:

1. Centre distance (PC size): The centre-to-centre distance between the handle spindle opening and the keyhole/cylinder opening.
2. Door thickness: This determines whether the bolts/screws are long enough without protruding.
3. Lock type: A passage/latch lock (room doors), a bathroom privacy lock, or a cylinder lock (security/exterior use).
4. Door handing: Not all hardware is universal—check the product specifications for compatibility.

Tip: Want a consistent look across your space? Combine matching door hardware with compatible door handles or additional door hardware accessories to keep the style unified.

Step 3: Pre-assemble the door hardware

Many products arrive as a set. Pre-assembling the parts first helps avoid misalignment or incorrectly positioned rosettes/backplates.

1. Lay out all components of the door hardware set (handles/pulls, spindle, rosettes or backplates, fixings).
2. Slide the handle(s) onto the square spindle (if applicable) and check the fit—everything should move smoothly.
3. Position the rosettes or backplates in the correct place without tightening fully yet.
4. Check alignment: are both sides level, and do the rosettes sit neatly against the door surface?

Step 4: Install the door hardware

Now it’s time to mount the hardware onto the door. Work carefully and re-measure if needed so the final result looks clean, straight and symmetrical.

1. Remove the old door hardware completely (handles, rosettes/backplates and any remaining screws).
2. Check that the lock is correctly fitted in the door and securely fastened.
3. Place the assembled hardware on both sides and insert the spindle through the lock.
4. Secure the rosettes or backplates using the correct screws and tighten evenly (avoid over-tightening).
5. Test the operation: does the door open and close smoothly, without wobble or stiffness?

For exterior doors, you may also want to choose suitable hardware from our exterior door hardware range for extra strength and a refined finish.

Step 5: Use door hardware correctly

Using your door hardware properly helps it stay in good condition and reduces unnecessary wear.

1. Operate the handle with normal pressure and avoid putting weight on it (no “hanging” on the handle).
2. Try not to slam doors—this puts extra strain on the lock and can loosen fixings over time.
3. In high-traffic areas, check occasionally whether rosettes/backplates are still tight and aligned.

Step 6: Maintain your door hardware

With simple maintenance, door hardware stays attractive and functional for longer—especially coated black finishes and hardware used in humid rooms.

1. Clean weekly or every two weeks with a soft, dry cloth.
2. For marks, use a slightly damp cloth with a mild cleaning product.
3. Avoid abrasive pads and aggressive cleaners (they can damage coatings and finishes).
4. Every six to twelve months, check whether fixings are still secure and tighten if necessary.

Frequently asked questions about door hardware

How do I know which centre distance (PC size) I need?

Measure the distance in millimetres between the centre of the handle spindle and the centre of the keyhole or cylinder opening. This PC size must match your existing lock for a correct installation.

How do I choose the right door hardware for my interior?

Match the style and finish to your interior and the type of door. Modern interiors pair well with black or stainless steel, while more classic spaces often suit brass or brushed steel.

What should I check before buying door hardware?

Always check the centre distance (PC size), door thickness and lock type—such as a latch lock, cylinder lock or bathroom privacy lock. These technical specifications determine whether the hardware fits correctly and operates smoothly. Checking this in advance helps you avoid installation issues and unnecessary returns.

Can I install door hardware myself?

Yes. Most door hardware sets are designed for straightforward DIY installation using standard tools. Thanks to complete kits and clear instructions, installation is usually quick and hassle-free. Even without technical experience, it’s typically easy to do yourself.

Which door hardware is suitable for bathrooms or humid rooms?

Stainless steel door hardware is the best choice for humid rooms because it is rust-resistant. It is low-maintenance and performs well in environments with condensation and water vapour, helping it stay attractive and reliable long term.
