Run a tape measure along your door from the left corner to right corner, and record this number. It is important that you only measure the door. Do not include any other elements, such as weather-stripping.  Particularly with older doors, it is important to measure in more than one location, just in case the door is not perfectly rectangular. If the amounts vary, use the largest figure. Door widths of 30 inches (76 cm), 32 inches (81 cm) and 36 inches (91 cm) are considered "standard." Run your tape measure along your door from the top corner to the bottom corner, and write this number down. You may need to use a chair and/or ask a friend to help you. Once again, measure only the door itself and no other elements, such as a door sweep.  Once again, it is wise to measure in more than one spot on the door, just in case it's not a perfect rectangle. This is especially true for older doors. If the amounts vary, use the largest figure. The most common height for doors is 80 inches (200 cm). Hold a tape measure to the edge of the door and record its thickness. Measure this edge on the door frame (known as the jamb), as well. These numbers should be close to the same, but it can be helpful to know both of them. The most common thickness is 1.75 inches (4.4 cm). Just to be safe, measure the area where your door will go, too. Record the height and width of the door frame space. This will help ensure that you select the exact right replacement door.  Measure the width of the door in 3 locations. Use the smallest figure as your measurement. Measure the height of the door right in the middle. Measure from the floor to the underside of the trim at the top of the door. If you must, it is always better to round down than round up. This helps to ensure that your door will fit.
