In 2026, trends lean toward sustainable fabrics like cotton and linen, layered boho looks, seasonal swaps with Christmas pillow slipcovers, and practical features like zippered closures for easy cleaning.

By the end, you’ll know exactly how to choose 18×18 pillow covers, style green accent pillows for a grey couch, or maintain your 20×20 pillow covers for years.
The Master Sizing & Dimensions Chart
Choosing the right pillow size prevents that awkward “too small” or “overstuffed” look. Here’s a clear pillow size chart with common dimensions, best uses, and notes for your keywords like typical pillow sizes, standard size pillow dimensions, and specific covers (18×18, 20×20, 24×24).
Pillow Size Chart 2026
| Pillow Type | Common Dimensions | Best Use Case | Notes / Keywords Covered |
| Standard/Bed Pillow | 20″ x 26″ | Sleeping, bedroom pillows | Standard size pillow dimensions, pillow size queen, pillow lengths |
| Small Square Throw | 18″ x 18″ | Sofa pillow covers, accent chairs | 18×18 pillow covers, pillow covers 18×18, throw pillow covers 18×18 |
| Medium Square Throw | 20″ x 20″ | Couch pillows, main sofa accents | 20×20 pillow covers, pillow covers 20×20, pillow covers 20×20 inch |
| Large Square Throw | 24″ x 24″ | Massive floor pillows, large couch backs | 24×24 pillow cover, pillow covers 24×24 |
| Euro Sham | 26″ x 26″ | Decorative bed pillows, layered bedding | Euro sham vs pillowcase, sham vs pillowcase |
Pro Tip: If your bed pillow is 22 x 16 inches, it’s a slightly non-standard size (common in some older sets or custom options). It usually fits comfortably in a standard pillowcase, but opt for a zippered pillow cover for a snugger fit and easier washing. For square pillows, 20×20 is the most versatile for couches big enough to make a statement without overwhelming the space.
These sizes are the most popular in 2026, based on Amazon and home decor retailer trends. Always measure your insert before buying covers!
Styling by Room: From Boho to Christmas
Pillows let you experiment with color, texture, and trends without big commitments. Here are practical styling tips integrating your keywords like boho throw pillows, green accent pillows, gold throw pillows, and Christmas pillow slipcovers.
The Sofa Setup: Couch Pillows with Covers
For a grey couch, start with 3–5 pillows for balance. Use green pillows for grey couch (sage green accent pillows for a calming, earthy vibe, or darker green pillows for light grey couch to add contrast). Mix sizes: one 24×24 pillow cover in the center, flanked by 20×20 and 18×18. Add black accent pillows or brown accent pillows for depth. Couch pillow slipcovers make swaps easy, choosing zippered for quick changes.
Seasonal Swaps: Christmas & Holiday Vibes
Update instantly with Christmas pillow slipcovers (red/green festive patterns or subtle reindeer designs). Pair with gold throw pillows for sparkle, or blush pink floral pillows for a softer holiday look. Throw pillow slipcovers allow seasonal rotation without buying new inserts.
Textural Trends: Boho & Beyond
Boho decorative pillows and boho couch pillows shine with tassels, fringes, and natural fabrics. Mix linen pillow covers with boho throw pillows for that effortless “designer” feel. Floral decorative pillows add romance, try blush pink floral pillows on a neutral sofa. For colorful accents, pink throws and pillows or blue sofa pillows bring energy.
Bedroom Pillows & Accents
Layer bedroom pillows with euro shams for height. Use cotton decorative pillows or floral pillows for texture. Square pillows (18×18 or 20×20) work great on beds too.
Pro tip: Pillows for grey couch look best in groups of odd numbers three or five for visual interest.
Construction & Hardware: Sham vs. Pillowcase
Understanding pillow construction helps you choose the right one for function vs. form.
Pillow Sham vs Pillowcase
- Pillow Sham: Decorative with flange edges (extra border for a tailored look). Usually has an envelope or button closure on the back. Ideal for show pillows (bed toppers, sofa accents). Not meant for sleeping more for styling.
- Pillowcase: Open-end design for easy insert/removal. Utility-focused for sleeping pillows. Many have a flap or zipper for security.
Closures & Hardware
- Pillow case with zipper: Best for outdoor pillowcase covers (keeps debris out) and easy washing. Superior for decorative pillows too zippered pillow covers prevent shifting.
- Envelope closure: Common on shams overlapping fabric for a clean front.
Choose zippered for couch pillow slipcovers or outdoor use easy to remove and clean.
The Maintenance Lab: How to Wash & Clean
Dirty pillows kill the vibe. Here’s how to wash throw pillows, clean decorative pillows, and maintain couch pillows without damage.
General Rules
- Always check labels (machine-washable vs. dry clean only).
- Spot test colors on cotton & linen pillow covers.
- Remove inserts if possible (most decorative have zippers).
Step-by-Step: How to Wash Throw Pillows & Couch Pillows
- Vacuum first to remove dust.
- Spot clean stains with mild detergent.
- Machine wash (gentle cycle, cold water, mild soap). For non-removable inserts, use a large-load washer.

Specific Tips

- How to clean decorative pillows: Same as above, avoid hot water on linen.
- How to wash decorative pillows with inserts: Remove and wash inserts separately if possible.
