How to Choose the Right Throw Pillow Size

Throw pillows can turn any space into a cozy and stylish spot, but picking the wrong size can throw off the whole vibe. Fear not, here are some tips to help you choose the right size for your home decor and make your space feel like a snuggly sanctuary:

Consider Your Furniture Size

Your furniture is the foundation of your decor, so you’ll want to make sure your throw pillow size compliments the size of your furniture. If you have a larger couch or sectional, go big with your couch pillows to balance out the scale. On the other hand, keep it cozy with smaller pillows if you’re styling a small armchair or twin bed.

Factor in Your Personal Style

Your personal style is what makes your space unique, so it’s essential to let it shine through your decorative throw pillow choices. If you prefer a minimalist look, opt for smaller pillows. If you want to make a statement, go bold with larger pillows.


Mix and Match Pillow Sizes

You don’t have to stick to one size only. Mixing and matching different sized pillows can add visual interest and balance to any space. Try different combinations and see what feels right for your space! Need some inspo for styling throw pillows in your living room? Check out our couch throw pillow ideas!

Consider the Room’s Purpose

Every room has a purpose, and your throw pillows should reflect that. If it’s a formal living room, go for structured and uniform sizes. But if it’s a cozy family room, mix it up with different sizes and styles to encourage lounging and relaxation.

Keep these tips in your back pocket and you’ll be well on your way to creating the coziest home around. Say goodbye to mismatched pillows and hello to ultimate comfort and style with the perfect throw pillow size!

Best Throw Pillow Sizes for Different Furniture

Because the size of your furniture matters when choosing a throw pillow, we’ve put together recommended throw pillow sizes for various furniture pieces:

Throw Pillow Size for a Standard Sofa

The 20×20-inch pillows work best for a 3-seater sofa, with a couple of 18×18-inch or lumbar pillows to add depth. If you have a 2-seater loveseat sofa, opt for an 18×18-inch pillow. You can accent it with a 16×16 inch or a lumbar pillow for variety.

Throw Pillow Size for a Sectional

Given the larger size, 24×24 inch pillows are ideal for the corners. Mix in some 20×20 inch and lumbar pillows for a layered look.

Throw Pillow Size for an Accent Chair

These chairs look great with a single 16×16-inch pillow or a lumbar pillow, especially if the chair is on the smaller side.

Throw Pillow Size for a Twin Bed

A single 18×18-inch or 20×20-inch pillow works well. You can also use a bolster pillow for a neat look.

Throw Pillow Size for a Full Bed

Two 18×18 inch pillows side by side or a combination of 18×18 inch and lumbar pillows give a balanced look.

Throw Pillow Size for a Queen Bed

Two 20×20-inch pillows, accompanied by a couple of 18×18-inch or lumbar pillows, create a plush and inviting look.

Throw Pillow Size for a King Bed

Given the width of a king bed, starting with two 24×24 inch pillows against the headboard, followed by two 20×20 inch pillows, and then a lumbar or bolster pillow in the front, can create a luxurious feel.
