We’re often asked questions like 'Will this handle fit my door?', 'What latch do I need?' or 'Can I keep my existing lock?' and it’s easy to see why. Door hardware can look simple on the surface, but a few key measurements make all the difference.
This guide breaks down the most common types of door handles and latches, explains what measurements matter, and helps you choose the right setup for your home.
Whether you’re replacing old handles or fitting new doors, this should make the process far more straightforward.
Types of Door Handles
1. Lever on Rose
Lever on rose handles are one of the most popular choices for modern and traditional homes alike.
They consist of a lever mounted on a circular or square backplate (rose) and are commonly used on internal doors and paired with a tubular latch.
Best for:
- Living rooms
- Bedrooms
- Dining rooms
2. Lever on Backplate
Lever on backplate handles are mounted on a longer plate and the size of this can help cover marks from previous fittings.
Common backplate types include:
- Latch (no locking)
- Lock (for use with a mortice lock)
- Bathroom (with thumbturn and release)
- Privacy (with thumbturn and release)
Note that the handle type must match the lock type inside the door.
3. Door Knobs
Door knobs are a classic choice for traditional and period properties.
Most of our door knobs are sprung and do not require a spring-loaded latch to operate correctly. Our knobs can often be paired with a standard tubular latch or mortice lock.
Choosing the Right Latch or Lock
Tubular Latches
Tubular latches are the most common choice for internal doors.
Common sizes:
- 63 mm
- 76 mm
The size refers to the case length, not the backset. Always measure your existing latch before replacing.
Mortice Locks
Mortice locks are used where security or privacy is required.
Typical uses include:
- Bedroom doors (with key or privacy lock)
- External doors (with higher security ratings)
When choosing a mortice lock, you’ll need to match:
- Backset
- Case size
- Spindle size (usually 8 mm in the UK)
Key Measurements You Need to Check
Before ordering any door hardware, it’s important to measure:
-
Door Thickness
Most internal doors are 35–45 mm thick. -
Backset
The distance from the edge of the door to the centre of the spindle hole.
Common sizes are 44 mm and 56 mm. -
Spindle Size
Most UK handles use an 8 mm spindle, but always check your existing hardware. -
Fixing Centres (for backplate handles)
This is the distance between the screw holes.
If you’re unsure, removing the existing handle and latch is the safest way to confirm measurements.
Finishes and Matching Hardware
When choosing finishes, consistency matters.
Popular traditional finishes include:
- Polished chrome
- Satin nickel
- Polished brass
- Matt Black
- Black Nickel
Tip:
For the best match, choose handles, hinges, latches, and accessories from the same finish, as finishes can vary slightly between manufacturers and batches.
Installation Tips
- Replacing like-for-like is usually straightforward with basic tools
- Always check alignment before fully tightening screws
- If upgrading locks or working on external doors, professional fitting may be worthwhile
Common Mistakes to Avoid
- Guessing measurements instead of checking
- Mixing finishes across handles, hinges, and accessories
- Installing handles before confirming door handing (left/right where applicable)
