Interior Door Rough Opening Sizes All You Need To Know

When planning the layout of your home, it's essential to consider the size of the rough opening for your interior doors. The rough opening is the space in the wall where the door frame will be installed. The size of the rough opening must be large enough to accommodate the door frame and the door itself. If the rough opening is too small, the door will not fit properly and will be difficult to open and close. If the rough opening is too large, there will be a gap between the door frame and the wall, which can look unsightly and allow drafts.

The standard rough opening size for most interior doors is 36 inches wide by 80 inches high. However, there are some variations in size, depending on the type of door and the manufacturer. For example, some doors may be 32 inches wide, while others may be 42 inches wide. The height of the rough opening may also vary, depending on the height of the door. It's always best to check the manufacturer's specifications for the specific door you are installing.

In addition to the width and height, you also need to consider the thickness of the door when determining the size of the rough opening. The standard thickness for most interior doors is 1 3/8 inches. However, some doors may be thicker, such as solid wood doors or fire-rated doors. If you are installing a thicker door, you will need to adjust the size of the rough opening accordingly.

Once you have determined the size of the rough opening, you can mark it out on the wall. It is important to use a level to ensure that the opening is square. Once the rough opening is marked out, you can cut it out using a saw.

Installing an interior door is a relatively simple project that can be completed in a few hours. However, it is important to make sure that the rough opening is the correct size before you begin. By following these tips, you can ensure that your interior doors fit perfectly and look great.

How to Measure for a Rough Opening

To measure for a rough opening, you will need a tape measure and a level. First, measure the width of the door frame. Then, measure the height of the door frame. Finally, measure the thickness of the door. Add 1/2 inch to the width and height of the door frame to determine the size of the rough opening.

For example, if the door frame is 36 inches wide, 80 inches high, and 1 3/8 inches thick, the rough opening will be 36 1/2 inches wide by 80 1/2 inches high.
