Door thresholds between two floor finishesThis section view supports door thresholds between two floor finishes by showing the relationship between the door bottom, finished floor, clearance and threshold.

Internal transitions can often be visually quiet. External thresholds have additional weather and drainage considerations. Measure both sides of the opening rather than treating the threshold as an isolated strip.
What to look at
Start with the opening, the condition of the existing door and frame, the way the space is used, and the finish you want to achieve. These details usually narrow the practical options quickly.
