How to Measure a Door Latch
Do you have a creaky door latch that needs to be measured and replaced? An ill-fitted latch may cause the door to malfunction and not open or close properly. But before buying a new latch, you’ll need to know the right size and measurements of your existing latch.
In this article, we'll provide you information on how to measure a door latch correctly in order to find the best replacement for your needs.
Follow the below mentioned steps to measure a door latch using a tape measure.
-
Measure the Case Size
Usually, there is already a hole cut in the backplate and door jamb where the casing slides into, so make sure to measure the case depth of that hole for even more precision. Finally, jot down any other dimensions such as screw holes and corner radius.
-
Measure the Bracket Size
A backset is what holds the latch in place and thus influences the measurement of the entire latch. The bracket is usually located at the top or side of the lever handle of the door, so start by carefully looking around until you locate it.
How to Select Correct Door Latches
When selecting door latches, it’s important to consider both the desired aesthetic as well as their practicality. The level of security is an important factor, and there are lever handles, door handles, and deadbolts available in various materials that provide different levels of theft deterrence. Make sure that the latch you select is strong enough to protect against whatever level of intrusions you are expecting.
For bathrooms and bedrooms, deadbolts may be the ideal option. Consider additional features such as easy access for an elderly person who might have difficulty lining up a key in a lock. Also, certain materials may be heavier or longer than others, so make sure that you know the latch size and measurements of your doors beforehand.
