When figuring out the right size for the hole where a rough opening for a 32-inch door will go, you need to consider how big the door is and the extra space it needs to fit correctly. A regular 32-inch door is usually 32 inches wide and 80 inches tall. But it would be best to double-check the exact measurements of the door you’re using because different brands might have small differences.

Manufacturer’s Instructions

These are similar to a guide manual from the folks who created the door. Following their directions ensures everything is done correctly and the door functions properly.

Getting the Correct Measurements

As said above, precision is crucial to any interior architecture – and when working with a 32-inch door, it has to be perfect! For that, the dimensions of the door must be accurate. The door’s average size corresponds to its actual width, which, in this case, is 32 inches. 

People usually add 2 inches to the door’s width and 2-1/2 inches to its height. So, the hole should be around 34 inches wide and 82-1/2 inches tall. This extra space lets you adjust things, use shims, and ensure the door fits well and moves smoothly in the frame.

It also gives you room to put in door frame extensions, which help the door frame blend in with the wall.

Recognizing the Importance of Rough Openings

The door’s rough opening is much more a cause of concern than you think. It is a well-designed frame that contains the key to the door’s function, lifespan, and overall beauty. In short, it is an underlying structure with more to do with the door’s endurance, performance, and visual attractiveness.

A well-built, rough opening ensures the door runs smoothly, fits tightly inside the frame, and offers enough insulation. If you neglect this by any chance, it is likely that your door will be misaligned, you will have inefficient energy use, and you may also have structural difficulties over time.

Tools and Materials Required to Make Perfect Rough Opening

Making a proper rough opening for a door requires using crucial equipment and materials to ensure that everything is exact and long-lasting. But before you go ahead, you’ll need to gather the necessary items beforehand to save time and effort.

  • Measuring Tape – A decent measuring tape can assist you in taking accurate measures. It will allow you to determine how large the rough opening should be for the door to fit precisely.
  • Level – A level is used as a reference to ensure that the door frame is straight up and down and not inclined. It makes the door operate more smoothly and looks nice.
  • Shims – Shims are little wedges that can be used to alter items. They are useful if the wall isn’t perfectly straight. Shims ensure that the door frame is the correct form and level.
  • Screws and Screwdriver – Using the proper screws and a screwdriver keeps the door frame firmly in place. These items will make the structure dependable and sturdy.
  • Insulation Materials – Materials such as foam or fiberglass keep heat inside and cold outside. It is like a warm blanket for your door, making the space more inviting.
  • Sealants – Sealants are special glues that prevent air and water from entering. They improve the door’s performance and safeguard it from harm.
  • Hammer – A hammer is useful for softly hammering objects into position. It helps make sure everything is secure and snug.
  • Saw – If the door frame has to be in a particular form, a saw can help you cut it precisely.

How Do You Measure the Rough Opening for A 32-Inch Door?

How Do You Measure the Rough Opening for A 32-Inch Door

1. Prepare the Area

Before you start measuring with measuring tape for a rough opening for a 32-inch door, you must prepare the area. First, clear the space near the door frame.

Take away any furniture, decorations, or things blocking the way. Make sure the area is clean with no junk around. This is important because it helps you see the door frame clearly without obstructions, making measuring more accurate.

2. Gather the Necessary Tools

You’ll need a few important tools to get the right size for a rough opening for a 32-inch door. Make sure you have a measuring tape, a level, a pencil, and a notepad ready. These tools will help you measure and make sure the door fits perfectly.

3. Measure the Width

To determine how wide the space should be for a rough opening for a 32-inch door, begin by measuring the gap between the two vertical wooden beams on both sides of the door frame. Use your tape measure to get a measurement.

Remember that for a 32-inch door, the space between the studs should also be 32 inches wide. If the measurement doesn’t match, you might need to twist the frame or use a different door size.

4. Determine the Height

To check the right size for your door, start by measuring the height of the opening where it will go. To do this, measure from the top of the door frame that horizontal piece above the door down to the floor. If you’re installing a rough opening for a 32-inch door, the height of this opening should be 80 inches. Ensure your measurement is exact to ensure the door fits nicely in that spot.

5. Account for Shimming

When you measure the space for your door, remember to consider using shims. Shims are tiny wedges you insert between the door frame and the space where the door goes. They help make sure the door is level and straight. To do this, leave a small gap of about 1/8 to 1/4 inch on both sides of the door frame. This gap allows you to make small adjustments when installing the door so it fits perfectly in the space.

6. Consider the Door Frame Thickness

Remember to include the door frame’s thickness to find the right width for your door’s space. Usually, a regular rough opening for a 32-inch door comes with a frame that’s about 1 3/8 inches wide.

To determine the total width you’ll need for the opening, add the door’s width (32 inches) to the frame’s thickness of 1 3/8 inches. So, if you have a 32-inch door with a standard frame, your rough opening should be 33 3/8 inches wide.

A sequence of exact processes is required to achieve a beautiful rough opening for your 32-inch door. Here’s a short guide to guarantee a smooth installation.

1. Measuring and Marking

Determine the width of the door slab to begin with. Just add 2 inches to whatever width measurement you achieve. Similarly, add two and a half inches to the measurement for the approximate opening height. Mark the precise placement of the rough opening on the wall using a level. Before you process, double-check these dimensions and markings.

2. Removal of Existing Frame

This step only applies if you have an existing door. Carefully remove the door first and then uninstall the frame. However, be careful and avoid damage to the surrounding wall. This stage may need patience and a careful touch.

3. Structural Assessment

Examine the surrounding structure for blockages, such as electrical cables, pipes, or load-bearing components, that might hamper the installation procedure. If you find any of these near the installation area, encase them so that it does not interfere. Safety and structural integrity are of utmost importance.

4. Frame Installation

Now comes the most crucial part, wherein you will install the door’s foundation. Follow the manufacturer’s directions for installing the door frame. Shims can secure the frame and ensure it is level and plumb. This is the foundation for a sturdy and well-fitting door.

5. Install the Header and Still Components

Attach the header and still components to the frame structure. Ensure these pieces are aligned correctly and leveled since they give structural support and stabilize the door.

6. Precision Adjustment

Please carefully look over the frame for any anomalies. If you need it, please make careful adjustments using shims to ensure a snug and accurate fit. Please ensure the frame is square and level to avoid any operating difficulties with the door.

7. Sealing and Insulating 

Apply insulation around the frame to improve energy efficiency and soundproofing. For instance, you can use appropriate materials to fill the gap between the wall and the frame. This process eliminates moisture intrusion and drafts. Ultimately, it assures a long-term performance.

8. Installing the Door

Insert the 32-inch door slab into the frame. Take note of the door’s alignment, smooth functioning, and secure latch. Also, take time with this step, as it significantly impacts the door’s function.

Plus, it lets you add insulation, which helps the door fit easily and seal properly. This keeps out drafts and saves energy. A larger rough opening is also handy because doors and frames can vary in size due to manufacturing differences. So, even if they’re not exactly the size they’re supposed to be, a bigger rough opening ensures that your door will fit.

This flexibility simplifies the installation process, which is great for both do-it-yourselfers and professionals.
