Part 3: How to Measure for Cushion Covers

Accurate measurements are essential for a proper-fitting cover. Incorrect measurements lead to covers that are too tight, too loose, or misshapen.

Measuring Couch and Sofa Cushions

Seat Cushion Measurements

Step 1 – Width: Measure the full width of the cushion at its widest point, including any piping or trim. (Example: 28 inches)

Step 2 – Depth/Length: Measure from the front edge to the back edge at the deepest point. (Example: 24 inches)

Step 3 – Height/Thickness: Measure from the bottom to the top with the cushion lying flat—do not compress it. Add 0.5″ for zipper allowance. (Example: 4 inches)

Back Cushion Measurements
Many sofas have separate back cushions. Measure width, height, and depth the same way as seat cushions. Back cushions are often larger and may require separate covers.

T-Cushion Measurements
T-cushions require two separate covers:

  • T-bottom section: typically 20×24.”
  • T-back section: typically 28×20.”

Dimensions vary significantly between sofas, so take careful measurements of each section individually.

  • Common sizes: 40×16″, 48×16″, and custom dimensions

Measuring Chair Cushions

Dining Chair Cushion

Step 1 – Seat surface: Measure length (front to back) and width (side to side). Standard sizes: 16×16″, 18×18″

Step 2 – Thickness: Measure height when the cushion rests naturally. Typical: 2–3 inches

Step 3 – Attachment method: Note whether ties attach to the chair legs or the chair back, as this determines the cover design.

Rocking Chair Cushion
Rocking chairs have a special curved shape. Measure the chair contours carefully—width, length, and thickness. Custom sizing is usually required.

Egg Chair Cushion
Measure the hanging pod dimensions: width of the pod opening, depth of the seat area, and height from the base. Custom measurements are typically needed.


Measuring Specialty Cushions

Breastfeeding Pillow: Measure length, width/girth, and thickness. Typical: 12–16″ circumference

Meditation/Yoga Cushion: Measure diameter (if round) or length (if rectangular), plus height. Typical: 12–15″ diameter, 4–6″ tall

Wheelchair Cushion: Measure seat surface width, depth, and thickness. Roho Mosaic cushion standard width: 20.25″


Part 4: DIY Sewing Techniques

Making your own cushion covers is more achievable than most people expect—especially when you follow the right instructions.

Essential Sewing Supplies

Equipment:

  • Sewing machine (a basic model is sufficient)
  • Measuring tape
  • Scissors or rotary cutter
  • Pins or clips
  • Chalk or fabric marker
  • Needle and thread (for hand stitching)
  • Seam ripper (for correcting mistakes)
  • Iron and ironing board

Materials:

  • Fabric (amount based on cushion dimensions)
  • Zipper (if a zip closure is desired)
  • Matching or coordinating thread
  • Batting or lining (optional, for added structure)

Zipper types:

  • Invisible zippers: seamless, polished appearance
  • Standard zippers: straightforward and functional
  • Separating zippers: best for larger cushions

Method 1: Basic Envelope Cushion Cover (No-Zip Style)

The simplest method—ideal for beginners.

Materials needed: Two fabric panels, thread, pins

Step 1 – Cut the fabric
Calculate: cushion width + 1″ = panel width; cushion depth + 1″ = panel depth. Cut two identical rectangular pieces.
Example: For a 20×20″ cushion, cut two 21×21″ pieces.

Step 2 – Place right sides together
Lay the two fabric pieces with right sides (the decorative sides) facing each other. Pin all edges and align corners carefully.

Step 3 – Sew three sides
Using a ½” seam allowance, sew three sides, leaving one side open. Begin at a corner, sew in a straight line, and backstitch at both the start and end to secure. Pivot at corners by stopping the needle, lifting the presser foot, and turning the fabric.

Step 4 – Trim the corners
Cut a small triangle from each corner (without cutting into the stitching) to reduce bulk and help corners lie flat once turned.

Step 5 – Turn the right side out
Reach through the opening and pull the cover through. Gently push out the corners using a pencil eraser.

Step 6 – Press the edges
Iron all four edges flat for a crisp, neat finish. Fold the raw edges of the open side inward by ½” and press flat.

Step 7 – Insert the cushion
Slide the cushion into the cover through the opening. Adjust until the cushion sits evenly in all corners.

Step 8 – Close the opening
Fold the pressed edges inward, pin shut, and close using a ladder stitch for an invisible seam. Use small stitches approximately ¼” apart and knot the thread at both ends.

How to sew a ladder stitch:

  1. Bring the needle up through the fold on one side
  2. Cross to the opposite side and enter the fold
  3. Bring the needle back out ¼” along the fold
  4. Cross back to the first side and enter the fold
  5. Repeat to the end of the opening and knot securely

Method 2: Boxed Cushion Cover (Professional Look)

This method creates a cushion cover with gusset (boxed) sides for a polished, professional finish.

Materials needed: Top and bottom fabric pieces, gusset strips, zipper, thread, and optional piping

Key measurements:

  • Top/bottom pieces: cushion width + 1″ seam allowance x cushion depth + 1″
  • Gusset width: cushion thickness + 1″ for seam allowances
  • Gusset length: full perimeter of the cushion

Example for a 20x20x4″ cushion:

  • Top/bottom panels: 21×21″
  • Gusset: 5″ wide (4″ + 1″)
  • Gusset length: 81″ (80″ perimeter + 1″ overlap)

Step 1 – Prepare the gusset
Measure the cushion’s full perimeter: (width x 2) + (depth x 2). Cut gusset strips and join short ends if necessary. Add ½” seam allowance to the width.

Step 2 – Insert the zipper
Center the zipper within one section of the gusset to create the cushion opening. The zipper length should roughly match the cushion width.

Step 3 – Attach piping (optional)
Baste piping around the outer edges of the top and bottom panels before attaching the gusset. Piping gives the cover a refined, finished look.

Step 4 – Attach the gusset to the top panel
With right sides facing, pin the gusset around all edges of the top panel. Sew a ½” seam, using a zipper foot near the zipper. At each corner, stop ½” before the edge, backstitch, pivot, and continue. All four corners should be mitered.

Step 5 – Attach the gusset to the bottom panel
Repeat the same process, pinning and sewing the gusset to the bottom panel with right sides together.

Step 6 – Turn and press
Turn the cover right side out through the zipper opening. Push corners out gently and press all edges flat with the iron.

Step 7 – Insert the cushion
Open the zipper fully, slide the cushion in, adjust to the corners, and close the zipper.

How to create mitered corners:

  1. Stop sewing ½” before the corner and backstitch to secure
  2. Lift the presser foot
  3. Fold the gusset at a right angle (as if wrapping a parcel corner)
  4. Lower the presser foot and continue sewing along the next side

Method 3: Cushion Cover with Zipper (Envelope Style)

Simpler than the boxed method, with the convenience of a zipper closure.

Materials needed: Two fabric pieces, one zipper (length = cushion width), thread, zipper foot

Step 1 – Cut the fabric

  • Front piece: cushion width + 1″ x cushion depth + 1″
  • Back piece: cushion width + 1″ x (cushion depth x 2)—the extra length accounts for the zipper fold

Step 2 – Prepare the back piece
Fold the back piece in half lengthwise with the wrong sides facing out. Press the fold with an iron.

Step 3 – Attach one side of the zipper
Open the zipper. Place one side of the zipper along the folded edge of the back piece, right side of the zipper against the wrong side of the fabric. Pin, then sew along the zipper edge using the zipper foot.

Step 4 – Attach the other side of the zipper
Fold the back piece over the zipper and align the raw edges. Pin and sew the second side of the zipper, sandwiching it between the back panel layers.

Step 5 – Join front and back panels
Partially open the zipper. Place the front and back panels right sides together, aligning all edges. Pin in place.

Step 6 – Sew around the cover
Using a ½” seam allowance, sew around all four sides. Use the zipper foot when passing over the zipper area. Pivot at the corners.

Step 7 – Trim and turn
Trim corners to reduce bulk. Turn the cover right side out through the zipper opening. Push corners out gently and press edges flat.

Step 8 – Insert the cushion
Open the zipper fully, slide the cushion in, adjust to the corners, and close the zipper.


Method 4: T-Cushion Cover

T-cushion sofas require two separate covers—one for the bottom section and one for the back section.

Bottom T-cushion cover (smaller, wider):
Apply the boxed or envelope method using the dimensions of the T-bottom section.
Typical size example: 22×20″

Back T-cushion cover (taller, wider):
Apply the same method using the dimensions of the T-back section.
Typical size example: 28×20″

The key distinction with T-cushions is that each cushion section has a different shape and must be measured and sewn separately.


Part 5: Installation Methods

Proper installation keeps covers looking their best and secures them in place.

Tie-On Installation (Chair Cushions)

Best for: Dining chairs and decorative cushions

  1. Place the cushion on the chair
  2. Thread the ties through the chair legs or around the frame
  3. Pull the ties taut and secure with a bow or knot
  4. Adjust the cushion position as needed
  5. Retighten ties if the cushion shifts with use

Typical tie length: 12–18″ for secure fastening


Slip-On Installation (Couch Cushions)

Best for: Couch and sofa cushions

  1. Remove the cushion from the sofa
  2. Align the cover opening with the cushion
  3. Ease the cushion into the cover
  4. Ensure all corners align correctly
  5. Smooth out any wrinkles and replace the cushion on the sofa

Tips:

  • Work on a clean surface to avoid transferring dirt
  • Ease the fabric gently—do not force the cushion, as this can tear the cover

Zipper Installation (Removable Covers)

  1. Open the zipper fully
  2. Align the cover opening with the cushion
  3. Ease the cushion in, ensuring all corners are fully inserted
  4. Check that the cover lies flat
  5. Close the zipper slowly, checking that no fabric is caught in the teeth

Zipper care tips:

  • Slide the zipper smoothly—never force it
  • Keep the zipper clear of lint and debris
  • A well-maintained zipper should glide effortlessly

Snap or Button Installation (Outdoor/Specialty Cushions)

  1. Align snaps or buttons with their corresponding hardware
  2. Fasten each snap or button securely
  3. Check alignment and adjust the cushion position as needed

Maintenance: Inspect snaps and buttons regularly and replace any that are damaged to ensure a secure fit.

FAQs: Cushion Cover Size

How do I make a cushion cover without sewing?
No-sew options include fabric glue and iron-on hem tape, though these are generally less durable than sewn covers. Envelope-style covers require minimal sewing, and closing an opening with a ladder stitch takes only 15–20 minutes by hand—well worth the effort for a longer-lasting result.

Can you wash couch cushion covers?
Yes, most are machine washable. Always check the manufacturer’s care label first. Use cold or warm water, a gentle cycle, and mild detergent. Tumble dry on low heat or air dry. Delicate fabrics such as velvet or silk may require dry cleaning.

How do I sew a cushion cover with a zipper?
Insert the zipper into the back panel before joining it to the front panel. Place right sides together with the zipper centered along the bottom edge, then sew using a zipper foot. Join the front and back panels, then turn the cover right side out through the partially open zipper.

What’s the best way to install outdoor cushion covers?
Most outdoor covers attach via ties or snaps. Place the cushion on the furniture, thread the straps through the chair legs or around the frame, pull taut, and tie securely. Check ties after washing to make sure they haven’t stretched or weakened.

How often should I wash cushion covers?
Monthly washing is typical for frequently used furniture. Spot clean spills as soon as they happen. Increase washing frequency if you have pets, children, or regularly eat on the furniture. Outdoor covers require less frequent washing unless exposed to harsh weather.

Can I use regular fabric for outdoor cushion covers?
This is not recommended. Standard cotton or linen will absorb water and fade quickly in UV light. For outdoor covers, use purpose-made outdoor fabrics such as Sunbrella or other performance fabrics, which are designed for weather resistance and durability.

How do I measure for a custom T-cushion couch cover?
Measure the bottom T-section (typically 18–24″ wide x 20–24″ deep) and the back section (typically 24–32″ wide x 20–24″ tall) separately. T-cushions require two individual covers for a proper fit.

Can you machine wash velvet cushion covers?
Machine washing velvet is not recommended—dry cleaning delivers the best results. If washing is necessary, use cold water and a delicate cycle, then hang to air dry completely. Always test on a hidden area first.

How do I keep cushion covers from sliding around?
Use non-slip shelf liner, furniture grips, or anti-slip mats under cushions. Tie-on covers also help significantly. Ensure the cover fits correctly—slightly snug is ideal. For extra security, attach small Velcro dots to both the cover and the furniture.

What fabric is best for high-traffic areas?
Microfiber is an excellent choice: stain-resistant, durable, and easy to maintain. Quality polyester and performance fabrics are also strong options. Avoid delicate materials such as velvet or silk in high-traffic spaces.


The Bottom Line: Better Covers, Better Furniture

Whether you sew custom covers from scratch, buy replacements off the shelf, or combine both approaches, the right cushion covers protect your furniture and refresh your décor without breaking the budget.

Take the time to measure accurately, choose materials that suit your lifestyle, and don’t hesitate to try sewing—it’s far more achievable than it looks. Well-made covers that fit properly can genuinely elevate an entire room.
