Choose The Right Function
Knowing the type of handle you need for specific rooms requires a basic understanding of door handle functions.

STEP 1:
KEYED ENTRY
Features: A keyed Entry handle features a turn button lock on the inside, and a keyhole on the outside.

STEP 2:
PRIVACY
Features: A Privacy handle features a push button lock on the inside, and an emergency key on the outside.

step 3:
PASSAGE
Features: A passage handle does not have a locking function, but it does turn freely.

STEP4:
DUMMY
Features: A dummy handle features just a single knob or lever without a latch, so it does not turn.
IN SUMMARY
Make sure there is a consistent theme throughout your lighting fixtures, sink faucets, cabinet pulls, and interior and exterior door knobs. Although you don't have to choose the same shapes and colors for all your hardware, you should make sure they complement each other nicely so that your home should have a consistent, uniform appearance.
