Imagine ordering a brand-new cozy comforter for your bed, but upon arriving, it’s too big and not what you hoped for. This can happen when comforter sizes don't quite match up. Typically, comforters correspond to standard mattress dimensions, including twin, full, queen, king, and California king.

The right size comforter can do more than just look good in your bedroom — it can positively impact your sleep quality. According to the Centers for Disease Control and Prevention (CDC), 37% of adults don’t regularly get the recommended amount of uninterrupted sleep they need to protect their health.¹

It’s no secret that a good night’s sleep can improve your overall mood. But good quality sleep can also lead to: 

• Better heart health
• Regulated blood sugar
• Improved mental function
• Restored immune system
• Stress relief

Choosing the right size comforter helps regulate your body temperature throughout the night, preventing disruptions and promoting deeper, more restful sleep for improved overall health and well-being.

Below, we’ll break down everything you need to know about choosing the right comforter size for your mattress, including a helpful chart and tips on how to achieve the perfect fit.

Comforter Size Dimensions

Comforter size dimensions can vary depending on the type of bed you have, and getting the right fit is crucial for both comfort and appearance. Before choosing a comforter, it’s important to consider factors like mattress thickness and the desired amount of overhang for extra warmth or style. 

Once you've narrowed down your preferences, knowing standard comforter sizes and how they fit different mattress dimensions will help you choose the best option.

King vs. Queen Comforter Size

When comparing king and queen comforter sizes, the main difference lies in their dimensions and how they correspond to the bed size:

• Queen comforters measure around 88-by-92 inches, making it ideal for a queen mattress, which is 60-by-80 inches. 
• King comforters are larger at 104-by-92 inches and are designed to fit a king mattress that measures 76-by-80 inches.

How To Measure Your Mattress

Measuring your mattress is the first step to finding the right bedding fit. Whether you’re upgrading your sheets or comforter, knowing the exact dimensions ensures comfort and prevents any awkward gaps. 

Simply use a tape measure to check the length, width, and thickness for an accurate size, especially if your mattress is non-standard or has a thick topper.

Step 1. Measure Length and Width

Capture the length and width by doing the following: 

• Length: Measure from the head of the mattress (top edge where your pillow goes) to the foot (bottom edge where your feet rest).
• Width: Measure from one side of the mattress to the other, across the middle.

It’s important to measure directly on the mattress itself, not the bed frame, as the frame may add extra dimensions. If you're planning to use a bed frame with a headboard or footboard, account for those when determining how much fabric you'll need for your comforter.

Step 2. Measure Depth and Thickness

Depth and thickness help ensure your comforter has the right drape over the sides of your bed.

Measure from the top surface of the mattress down to the bottom edge, including any mattress topper or padding. A thicker mattress may require a comforter with more drop, so you'll want to know this measurement to ensure the comforter hangs properly without looking too short.

Step 3. Put it All Together

Now that you have your length, width, and depth measurements, you can determine the right comforter size. Use the depth measurement to assess how far over the side the comforter will hang, ensuring it covers the sides evenly. Here’s how to choose the right comforter size based on your mattress measurements:

• For a snug, tailored fit, match the comforter size to your mattress dimensions.
• For more drape and a luxurious look, you’ll want a comforter that's a few inches wider and longer than your mattress. 

Considerations For Choosing the Right Comforter 

Choosing the right types of comforters involves more than just size — consider your material, thickness, fit, and budget to find the perfect match for your sleep style and climate. To help you make an informed decision, here’s a breakdown of key factors to consider when selecting the perfect comforter:

• Material:
  • Cotton: Breathable and soft
  • Polyester: Affordable and wrinkle-resistant
  • Down: Warm and light, but higher maintenance
  • Down alternative: Ideal for allergies or synthetic preferences
• Thickness:
  • Thicker comforters are better for colder months; thinner ones suit warmer weather
• Size & Fit:
  • Choose a comforter slightly larger than your mattress for optimal coverage and style
• Cost:
  • Prices range from $50 to $200; higher for down or premium options, lower for synthetic or cotton

Is a Comforter Right for You?

Choosing the right comforter goes beyond just size — it’s about finding the perfect balance of warmth, weight, breathability, and style to suit your bedroom. Opt for a comforter if you get chilly at night, prefer extra blankets, or simply like the look.
