Cushion Size Guide: Styling Tips for Sofas, Beds & Accent Chairs

When it comes to cushions, size really does matter!  And not just for comfort, but for style. The right dimensions can take your couch from mediocre to magazine cover-worthy. For a standard sofa with a depth of 36–40 inches, 18×18 or 20×20 inch cushions will look balanced without eating up too much seating space. If you’ve got one of those cushy deep couches, 22×22 or even 24×24 will feel perfectly proportioned. And for more compact, shallow seats, stick with 16×16 or 18×18 so you don’t overfill the space. Don’t be afraid to change things up,  a couple of larger squares in the back, some slightly smaller ones in front, and maybe a lumbar in the middle can work as well.

Cushions for Beds: Layer Like a Pro Stylist

Beds, on the other hand, are all about layering like a pro stylist! For a clean, minimal look, a single 36×14 lumbar across the bed works beautifully. If you like things a little more filled out, layer three 18×18 cushions behind that long lumbar for depth and texture. Do you want something even simpler? Just place two 14×20 cushions in front of your pillows - it’s quick, clean, and incredibly classy. Whatever arrangement you choose, make sure your cushions complement your quilt and bed cover so the whole look feels curated and pulled together.

Accent Chair Cushions: Keep It Simple and Stylish

For accent chairs, think simple and stylish. A single lumbar cushion is your best bet here - they just look better on single chairs. Go for a 12×18 or a 14×20, depending on the chair’s size and your style. It adds comfort without overpowering the silhouette of the chair. And here’s a little styling secret we swear by at Craft & Kar - we size our cushion covers about ½ to 1 inch smaller than the filler so the cushion feels perfectly filled out and luxuriously stuffed. Because at the end of the day, your cushions aren’t just there for support. They’re there to give your space the warmth it needs.
