The main difference between a sprung and an unsprung doorknob is that a sprung doorknob has a spring mechanism to return the doorknob to its original position after use.
As a national distributor, we receive a lot of questions regarding the difference between the two. In this article, we aim to clarify the differences to allow you to make an informed decision.
Sprung Doorknobs
By purchasing a sprung doorknob, you will find it comes equipped with a spring cassette. This cassette will be fixed to the backplate, the back of the doorknob, allowing it to return to its original position after use.
You will find that a sprung doorknob will have a deeper backplate than that of an unsprung doorknob. This is to accommodate for the spring cassette and it is worth noting the depth of the backplate to ensure it meets your requirements.

Unsprung Doorknobs
An unsprung doorknob will be reliant on the mechanism of the door's latch to return to its original position.
Over time, the latch may begin to wear out, and the doorknob will loosen slightly. This is because the handle does not return to its original position after use due to wear. As the wear continues, more force will need to be put on the handle and it may give out in time, potentially leaving you stuck on the other side of the door.
If you purchase an unsprung doorknob, it may be worth investing in a heavy sprung latch for your door to counteract the force placed on the latch.
It would also be worth noting that unsprung doorknobs can be replaced with a sprung doorknob. For more information on how to do change your doorknobs and handles, you can follow our easy guide on how to change door handles.

Which one do you need?
Having some more information from the experts, you can decide with confidence. Ultimately, the choice is up to you, but it may come down to the finer details of your door and your home.
- If you find you have a lower-quality door mechanism, it would be wise to choose a sprung doorknob to prevent the latch from loosening further. By selecting a sprung doorknob, your doors will enjoy longer-lasting latches. As they rely on their own internal, spring mechanism to operate the handle, less force is placed on the door's latch.
- If you own a higher quality mechanism, that does not need a spring to return the handle to its original position, you could opt for an unsprung doorknob.
Accessibility is also a factor you may want to consider. A sprung doorknob requires less effort to use as it returns to its position easily and without force. This is worth noting should you live in a home with dependents who may struggle to grip and turn the doorknob.
