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 pillows to balance out the scale. On the other hand, keep it cozy with smaller pillows if you’re styling a small armchair.

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!

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!
