Square Pillow Size Guide
The 18x18-inch square is the most versatile size, working on accent chairs, small sofas, and as bedroom layering pieces. The 20x20-inch square adds visual weight on standard sofas and loveseats. The 22x22-inch square makes a statement on deep sofas, sectionals, and king beds where smaller pillows can look lost.
Cover Only vs. Insert Included
Our collection includes both options. Loloi-branded pillows typically include a plush down-blend insert ready to use. Designer collaboration covers from Angela Rose, Amber Lewis, and Magnolia Home are often sold as covers only — pair with a same-size or one-inch-larger insert for a full, professional look.
Mixing Patterns and Textures
Start with a solid or near-solid pillow in your base colour. Add a geometric or striped pattern in the same colour family. Finish with a bold print or textured piece for contrast. Vary sizes by pairing 22-inch squares in back with 18 or 20-inch squares in front. Three to five pillows per sofa creates a layered, curated arrangement.
Frequently Asked Questions
What size square pillow is best for a sofa?
For standard sofas, 20x20 or 22x22-inch pillows work best. For loveseats and accent chairs, 18x18-inch pillows are proportional. Deeper sectionals can handle 22x22-inch pillows comfortably.
How many throw pillows should I put on a sofa?
Three to five pillows on a standard sofa creates a full, styled look without overcrowding. Use an odd number for visual balance. For sectionals, five to seven pillows distributed across the length works well.
Should I buy a pillow insert larger than my cover?
Yes, going one inch larger gives a plump, professional look. For an 18x18 cover, use a 19x19 or 20x20 insert. Down and down-alternative inserts compress more than polyester, so sizing up prevents a flat appearance.
