The “Will Sofa Fit Through Door Calculator” is a simple web-based tool designed to help users determine whether a specific sofa can fit through a door’s rough opening. Moving large furniture like sofas through narrow doorways can be challenging, and this calculator aims to eliminate any uncertainty by providing a clear answer.

User Interface

The calculator features an intuitive user interface with the following elements:

  • Two drop-down menus: Users can select the door’s rough opening width and the size of the sofa they intend to move.
  • “Calculate” button: Initiates the calculation process.
  • Result area: Displays the outcome of the calculation (whether the sofa will fit through the door or not).

Sofa Size Options

The calculator offers a range of sofa size options to cover various seating capacities, from single-seat armchairs to six-seat sofas. Users can select the appropriate sofa size based on their specific furniture.

Standard Door Rough Opening Widths

The calculator includes several standard door rough opening widths, such as 24 inches, 28 inches, 30 inches, 32 inches, and 34 inches. These dimensions represent common door sizes found in many households.

Sofa Dimensions

For accurate calculations, the calculator considers the width and depth of the selected sofa. The sofa width is the distance between the outer edges, while the depth represents the distance from the back to the front of the sofa.

Diagonal Calculation

To ensure greater accuracy in determining whether the sofa will fit through the door, the calculator also calculates the diagonal of the sofa using the Pythagorean theorem (a^2 + b^2 = c^2). This accounts for situations where the sofa can fit through the door diagonally, even if its width alone exceeds the door width.

How to Use the Calculator

  • Step 1: Select the door’s rough opening width from the drop-down menu.
  • Step 2: Choose the size of the sofa you want to move from the second drop-down menu.
  • Step 3: Click on the “Calculate” button to perform the calculations.
  • Step 4: The calculator will display the result, indicating whether the selected sofa will fit through the chosen door or not.

Interpretation of Results

  • If the calculator displays “Yes, the sofa will fit through the door,” it means the sofa’s dimensions are small enough to pass through the chosen door’s rough opening.
  • If the calculator displays “No, the sofa will not fit through the door,” it indicates that the sofa’s dimensions exceed the available space, and an alternative approach may be needed to move the sofa.

Additional Considerations

  • Be sure to measure the sofa accurately, taking into account any protruding elements like armrests or decorative accents.
  • If the door has an unconventional shape or size, consult a professional before attempting to move the sofa.
  • For narrow doorways, it may be possible to tilt or angle the sofa to facilitate entry.


The “Will Sofa Fit Through Door Calculator” is a valuable tool to help users plan their furniture moving process with confidence. By considering both the sofa’s width and diagonal dimensions, the calculator provides accurate results, ensuring a smooth and hassle-free experience when maneuvering sofas through doorways.
