Why give interior door handles some thought?
Handles affect both the look of a door and how it feels to open. Repeating a finish can connect adjoining rooms, while different designs can be used deliberately to suit individual spaces. Replacing handles may refresh a room without replacing the door, but the work required depends on compatibility and the door's condition.
Types of handle and fitting
Curved and angular levers
Choose a lever shape that feels comfortable and suits the door. A curved lever does not necessarily come on a round rose, nor does an L-shaped lever require a square rose. Lever shape and rose shape are separate design choices. Explore Knud Holscher's L handle for an architectural design.
Sliding-door fittings
Sliding doors may need recessed pulls, edge pulls or other dedicated fittings that allow the door to move freely. Check clearance, door thickness and any locking requirements. A general door-handle category does not mean every item suits sliding or folding doors.
Locks and privacy fittings
A lever set and a lock are different components. Depending on the door, you may need a key escutcheon, cylinder fitting or bathroom thumbturn with a compatible lock case. Check what is included. Do not assume an interior handle comes with a push-button lock.
Materials and finishes
- Brass: brass door handles add warmth. Unlacquered and coated surfaces age differently; check the exact treatment and care instructions. Read our brass door-handle guide.
- Steel: steel handles offer a cooler metallic look. Suitability depends on the grade, finish and intended use.
- Wood: wooden handles introduce natural texture. Check the construction and care requirements.
- Black: black handles can contrast with pale doors. Black is a colour or finish, not a base material.
- Chrome: a reflective surface finish; check the underlying material and product specifications.
Fixing centres: 30 or 38 mm?
For the roses discussed here, c/c means the centre-to-centre spacing of the fixing holes. The 30 and 38 mm arrangements are relevant to certain products, not universal standards for every country or door.
Measure the existing fixing centres and compare them with the new handle's drawing. Also check spindle size and length, door thickness, lock-case compatibility, the fixing method and whether the new rose covers existing holes or marks. Matching hole centres alone is not enough.
Do not drill through a lock case or enlarge holes without checking the manufacturer's instructions. See our guide to 30 and 38 mm fixing centres.
Arne Jacobsen's handle
The Arne Jacobsen lever handle, designed in 1956, brings a softly curved profile to the door. Choose from the variants actually listed and verify the specifications for your installation rather than assuming every finish or fitting arrangement is available.

Planning the installation
- Read the selected product's instructions and confirm compatibility before removing the old fittings. For a fire-rated or other special door, obtain confirmation that the replacement hardware is suitable before making changes.
- Keep the door open and supported. Remove the existing handles and roses using their actual fixing method; do not force decorative covers.
- Check the spindle, door thickness, lock operation, fixing positions and screw requirements.
- Fit the new parts in the order and with the tools specified by the manufacturer. Avoid overtightening or using screws that interfere with the lock.
- With the door still open, test that the lever moves freely, returns properly and operates the latch. Test any privacy mechanism and release before closing the door.
Stop if the handle binds, the latch does not work correctly or the parts do not fit. Seek installation help rather than forcing the mechanism. Our door-handle installation guide offers further context, but does not replace the product instructions.
Create connections between rooms
You can repeat a material or colour through cabinet handles, hooks, switches and sockets and doorstops. Compare actual finishes: similar names across manufacturers do not guarantee an exact match.
Consider each room's needs
- Hallway: consider frequency of use, grip and the product's intended duty.
- Bathroom: choose a compatible privacy fitting and a finish suitable for the conditions. Check the release function and what is supplied.
- Bedroom: choose the level of privacy you need rather than assuming a lock is unnecessary.
- Children's room: consider comfortable grip, edges and safe operation; a rounded shape alone is not a safety certification.
Frequently asked questions
What is the difference between 30 and 38 mm?
Here they describe rose fixing-hole centres. Measure and compare all relevant dimensions, including spindle and door thickness.
Must every handle be identical?
No. Repeating finishes creates continuity, but a deliberate mix can also work.
Can I fit the handles myself?
That depends on the door, hardware and your experience. Follow the instructions and use professional help for uncertain or special installations.
Which material is best?
Choose for appearance, feel, maintenance and the product's specified use. No material is best for every door.
Does an L-shaped handle need a square rose?
No. Check the particular design; the lever's outline does not determine the rose's shape.
