Creating custom armchair covers is a practical and rewarding way to refresh your living space without the investment of purchasing new furniture. Whether your current armchair is stained, faded, or simply outdated, a well-fitted cover can transform its appearance and extend its lifespan. This guide provides a detailed, step-by-step process to help you measure, cut, sew, and install professional-looking armchair covers.
Before you begin, it is essential to assess the condition and structure of your armchair. Not all armchairs are created equal; some have loose cushions, while others feature built-in arms or deep button tufting. You should determine whether you want to create a fitted cover that contours to the frame or a loose cover that slips over the entire piece like a pillowcase. Understanding the specific design of your chair will dictate the pattern and construction method you choose.
Tools and Materials You Will Need
Gathering the correct supplies is the first step toward a successful project. You will need high-quality fabric that is durable enough to withstand regular use, along with the necessary sewing implements. Investing in the right tools will make the process smoother and ensure a cleaner finish.

- Measuring tape
- Fabric scissors or a rotary cutter
- Pins or fabric clips
- Sewing machine or needle and thread
- Iron and ironing board
- Fabric marker or chalk
- Heavy-duty thread
- Zipper or fasteners (if required)
Measuring Your Armchair Accurately
Precise measurements are the foundation of a well-fitting cover. To avoid wasting fabric, you must capture the exact dimensions of the back, seat, and arms. It is recommended to have a second person assist you to ensure the tape measure stays taut and the chair remains stable during the process.
| Measurement Point | Description |
|---|---|
| Width | Measure from the outer edge of one arm to the other. |
| Depth | Measure from the front edge of the seat to the back of the chair. |
| Height | Measure from the floor to the top of the backrest. |
| Cushion Size | Measure the length and width of the seat cushion if it is removable. |
Calculating Fabric Requirements
Once you have your measurements, you need to calculate the total yardage required. A standard rule of thumb is to add an extra 2 to 4 inches to your measurements to account for seam allowances hems and overlapping panels. If you are using a patterned fabric, you may need additional fabric to ensure the pattern aligns correctly during the sewing process.
Cutting the Fabric to Size
With your calculations complete, transfer the dimensions onto the fabric using a fabric marker. It is often helpful to lay out the pattern pieces on the fabric to visualize the layout and minimize waste. When cutting, use sharp fabric scissors or a rotary cutter to ensure clean edges that will not fray excessively during handling.

If your design requires multiple panels—for example, separate pieces for the backrest and the seat—cut each piece individually according to your template. Pay close attention to the grain of the fabric; cutting straight along the grain helps maintain the structural integrity of the cover and prevents it from twisting or stretching over time.
Sewing the Main Components
Begin sewing by joining the main panels together, starting with the sides and back of the chair. Use a straight stitch for strong seams and finish the edges with a zigzag stitch or a serger to prevent unraveling. Press the seams open with an iron as you go; this step reduces bulk and ensures the cover lies flat against the frame.
If your armchair includes arms, attach these components next, ensuring they are aligned with the overall silhouette of the chair. For a more polished look, consider adding piping or welting along the edges of the arms or backrest. This detail adds a touch of sophistication and durability to high-wear areas.
Installing Fasteners and Final Fitting
Determining how the cover will stay in place is crucial for long-term use. For loose-fitting covers, you can insert a hidden zipper along the side or back seam to allow for easy removal and cleaning. Alternatively, you can use ties or straps that secure the cover to the legs of the chair, particularly if the seat cushion is removable.
Once the fasteners are installed, perform a test fit by placing the cover on the armchair. Make any necessary adjustments to tighten or loosen the fabric, ensuring that the cover drapes smoothly without sagging or pulling. This final fitting phase is where patience pays off, as slight tweaks can make the difference between a homemade look and a professional finish.
