Transforming a tired old armchair with a new cover is one of the most satisfying and cost-effective ways to refresh a room. Whether your current piece is stained, faded, or simply out of style, a DIY cover allows you to completely change its appearance without the commitment of permanent upholstery. This guide provides a detailed, step-by-step process for creating a professional-looking armchair cover, from taking precise measurements to finishing the final seam.
The beauty of a DIY armchair cover lies in its versatility; you can choose any fabric that suits your personal aesthetic and the existing decor of your space. From durable cottons and linens for high-traffic family rooms to luxurious velvets and wools for a sophisticated touch, the design possibilities are endless. This project is perfect for beginners looking to build their sewing skills and for experienced crafters who want to tackle a more complex upholstery challenge.
Essential Tools and Materials for Your Project
Before you begin, gathering the right tools and materials is the key to a smooth and efficient process. You will need a specific list of items to ensure your cover fits perfectly and looks polished. Investing in quality supplies will make the sewing experience more enjoyable and the final result more durable.

- Measuring Tape: A flexible, 60-inch measuring tape is essential for getting accurate dimensions of your chair.
- Fabric Scissors: A sharp pair of scissors designed for cutting fabric will ensure clean edges and prevent fraying.
- Pins or Clips: Use these to hold your fabric pieces together securely while you sew.
- Sewing Machine: A standard sewing machine is suitable for most projects; just ensure it can handle heavier-weight fabrics if you choose them.
- Iron and Ironing Board: Pressing your seams as you go is critical for achieving a professional, crisp finish.
- Seam Ripper: This handy tool is indispensable for correcting any sewing mistakes without damaging your fabric.
Step-by-Step Measurement Guide
Accurate measurements are the foundation of a well-fitting armchair cover. You must measure the width, depth, and height of your chair, including the armrests. Taking measurements for both the seated and backrest portions separately will help you create a pattern that drapes correctly over the furniture's unique contours.
| Measurement Type | Description | Why It's Important |
|---|---|---|
| Seat Width | Measure from the outer edge of one armrest to the other. | Determines the overall width of the cover's top section. |
| Seat Depth | Measure from the front edge of the seat to the back of the chair. | Ensures the cover hangs properly over the backrest without being too tight. |
| Backrest Height | Measure from the top of the seat to the top of the chair back. | Critical for cutting the correct length of the back panel. |
Designing and Cutting Your Pattern
With your measurements in hand, you can sketch a simple pattern on large crafting paper or even directly on the back of your fabric. Most armchair covers are created using a series of rectangles and basic shapes that are sewn together. A common design features a fitted back panel, two large side panels, and a series of ties or buttons that secure the cover in place, allowing for easy removal and washing.
When cutting your fabric, always add a seam allowance of at least ½ inch to every edge. This extra material is necessary for sewing the pieces together and will be hidden in the final seam. Consider the direction of the fabric grain and pattern; if your fabric has a specific nap or print, ensure all pieces are cut in the same direction to maintain a cohesive look across the entire cover.

Sewing the Main Components
The construction phase involves sewing the main panels together. Start by joining the side panels to the back panel, creating a long section that will wrap around the chair. Use a straight stitch for strong seams and finish the raw edges with a zigzag stitch or a serger to prevent unraveling. Pressing each seam open with an iron as you progress will significantly reduce bulk and create a flat, professional surface.
If your design includes a separate seat panel, attach it to the main body of the cover, leaving the front and bottom edges open for gathering. This method creates a pocket for the seat cushion and helps the cover sit smoothly over the frame. For chairs with arms, you will need to measure and sew additional pieces that fit snugly over the armrests, often requiring mitered corners for a neat appearance.
Adding Functional Closures and Finishing Touches
The final steps involve installing the closures that keep the cover secure. Ribbon ties are a popular and elegant option; simply sew two-inch-wide ribbons to the bottom corners of the side panels, leaving them long enough to tie in a bow at the back of the chair. Alternatively, you can add a hidden zipper to the back panel for a more streamlined look, though this requires a bit more advanced sewing technique.
Once all closures are attached, give the entire cover a final pressing. Hem any raw edges at the bottom or around ties if necessary, and inspect the stitching for any loose threads. Sliding the new cover onto the armchair and tying the ties provides the ultimate sense of accomplishment, instantly transforming the look of your space and proving the value of your DIY skills.
