Start by measuring your door closers hole spacing. Then mind a model that matches the door spacing that you currently have. If you can’t find the exact sizing, call a professional as they can make customized door stoppers.
However, the most common door stoppers sizes are:
- 3/4″ by 10-1/4″
- 1″ by 4-5/16”
- 9/16″ by 11-1/8″
- 2-1/8″ by 5”
If you can’t measure your door hole size, call and ask a professional for help. Sometimes specific door hole sizes are more complex to measure than others. Or you may have an obstruction.
