Frequently Asked Questions (FAQs)

1. What sizes do door thresholds come in?

The height of thresholds can vary anywhere from 1/4″ tall to 1″ or more. ADA requirements may restrict the height of the threshold to 1/2″ tall and a gradual incline no greater than 1/4″ in vertical rise. Thresholds can be supplied in widths from as small as 2″ wide up to 10″ or more.

2. What size threshold do I need?

Measure the space between the outside edges of the door casing. The new threshold should have a similar profile to your old threshold and be 1- to 2-inches longer than the length of the doorway so that you can trim it for an exact fit.

3. What is the difference between a door sill and threshold?

The door sill is part of the frame structure of the door and sits under the door jamb. The threshold sits on top of the sill and performs the duty of making the door weathertight.

4. What is the maximum height of a door threshold?

Thresholds at doorways shall not exceed 3/4 inch (19.1 mm) in height above the finished floor or landing for sliding doors serving dwelling units or 1/2 inch (12.7 mm) above the finished floor or landing for other doors.
