If you’ve ever woken up with a sore neck, found yourself constantly fluffing your pillow, or noticed that your bedding just doesn’t look quite right on your king-sized bed, it might be time to consider switching to king size pillows.
King size pillows, typically measuring 20 inches by 36 inches, offer more than just extra length—they provide enhanced comfort, better support, and a fuller, more luxurious look for your bed. While many people stick with standard or queen pillows out of habit, upgrading to king size pillows can be a small change that makes a big difference in your sleep quality and bedroom aesthetics.
But are king size pillows the right choice for everyone? Like any bedding upgrade, they come with their own set of pros and cons. In this post, we’ll break down everything you need to know—from the benefits and drawbacks of king pillows to our top recommended options for different sleep styles and budgets.
Whether you’re shopping for better support, a more cohesive bed setup, or simply wondering if bigger truly means better, this guide will help you decide if it’s time to make the switch.
What Is a King Size Pillow?
Before deciding whether to switch, it’s important to understand exactly what a king size pillow is—and how it compares to other common pillow sizes.
A king size pillow typically measures 20 inches wide by 36 inches long, making it 16 inches longer than a standard pillow and 10 inches longer than a queen pillow. That added length offers more room to move around, which is especially beneficial for restless sleepers or those who like to cuddle their pillow while they sleep.
These pillows are specifically designed to fit across a king-sized bed, where two king pillows span the entire width of the mattress. They also work well with California king beds, providing a clean, symmetrical look without leaving gaps at the edges.
Aside from bed size, king size pillows can be a good fit for:
- Side and combo sleepers who need more space or support
- Taller individuals who find standard pillows too short
- People who sleep with arms under their pillow or shift positions frequently
- Those looking for a more upscale or “hotel-style” bed appearance
Keep in mind that king size pillows require king-size pillowcases, which are longer than standard or queen ones. Thankfully, most bedding brands offer pillowcase sets specifically for king pillows, so it’s easy to find matching options.
Whether you’re aiming for better support or just want to upgrade your bed’s appearance, knowing the exact dimensions and intended use of king size pillows helps you make an informed choice.

Pros of King Size Pillows
Switching to king size pillows isn’t just about going bigger—it’s about enhancing your overall sleep experience. Whether you’re seeking better comfort, more functionality, or a more polished bed setup, king pillows offer several benefits that make them worth considering. Here’s a closer look at the key advantages:
1. Extra Sleeping Surface
The most obvious benefit of a king size pillow is its length. At 36 inches wide, it gives you more room to move, shift, or stretch out during the night without losing head or neck support. This is especially helpful for:
- Toss-and-turn sleepers who change positions frequently
- Combination sleepers who rotate between back, side, and stomach positions
- Couples who occasionally share a pillow or cuddle
More space means fewer interruptions and a more restful night.
2. Enhanced Support and Comfort
With extra surface area comes the potential for better head, neck, and shoulder alignment, especially when paired with high-quality materials like memory foam, down, or latex. Many king size pillows are designed to provide consistent support across the entire length, helping to reduce pressure points and promote spinal alignment—particularly for side sleepers and taller individuals.
3. Perfect Fit for King and California King Beds
Two king size pillows span the full width of a king-sized bed, offering a more cohesive and polished look. They also prevent awkward gaps between pillows, which not only looks better but also feels more comfortable when sitting up in bed to read or watch TV.
Even if you don’t sleep on a king bed, many people use king pillows for decorative purposes or for lounging support.
4. Versatility Beyond Sleep
King size pillows aren’t just for sleeping—they’re also incredibly versatile:
- Use one as a backrest while sitting up in bed
- Use it as a body pillow substitute for side sleeping
- Place one on a daybed or sofa for extra lumbar support
This flexibility makes them ideal for people who use their beds for more than just sleeping.
5. Aesthetic Appeal
Let’s face it—king size pillows add a touch of luxury. Their size helps create that plush, high-end, hotel-inspired look that many people want in their bedrooms. When dressed in elegant king-size pillowcases or shams, they make your bed look more complete and inviting.

Cons of King Size Pillows
While king size pillows offer plenty of advantages in terms of space, comfort, and aesthetics, they’re not ideal for every sleeper or bed type. Before making the switch, it’s important to weigh the potential drawbacks—especially if you’re working with a smaller space or have a specific sleep setup. Here are some of the most common downsides:
1. Not Ideal for Smaller Beds
King pillows are specifically designed for king and California king beds. When used on smaller mattresses like a twin, full, or even queen, they can look oversized and feel cramped. Their longer length can:
- Hang off the edges of the bed
- Overwhelm your headboard or decorative arrangement
- Crowd the sleeping space, especially if you’re using more than one pillow
Unless you’re using them for decorative or lounging purposes, king pillows may feel awkward on smaller beds.
2. Bulkier and Harder to Maintain
The extra size of king pillows makes them bulkier to handle, wash, and store. Some of the challenges include:
- Fitting them into standard-sized washing machines or dryers
- Needing extra closet or linen storage space
- Longer drying times (especially for memory foam or down fills)
For people with limited space or time, maintaining king size pillows may require more effort than smaller options.
3. Higher Cost
Generally speaking, king size pillows are more expensive than standard or queen pillows—not only in the initial purchase but also in accessories. Expect to pay more for:
- The pillow itself
- Pillow protectors
- King-size pillowcases and shams
- Coordinated bedding sets that fit properly
Over time, the added cost can add up, especially if you’re buying multiple pillows for a full bed set.
4. Limited Compatibility With Existing Bedding
If you already own a set of standard or queen-sized pillowcases, they won’t fit king pillows. This means you’ll need to invest in new covers, shams, or even complete bedding sets to keep everything looking cohesive. For some, this can be a minor inconvenience—for others, it might be a deal-breaker.
5. May Not Suit All Sleepers
While king pillows provide more surface area, not everyone benefits from the added length. For example:
- Stomach sleepers may prefer a thinner, shorter pillow
- People who sleep very still may not need the extra space
- Minimalists may find king pillows too bulky or overwhelming
In these cases, a queen or standard pillow may offer better comfort and fit.

Should You Switch? A Simple Decision Guide
Now that we’ve covered the pros and cons of king size pillows, you might still be wondering—is making the switch worth it for you?
This section helps you make that decision based on your personal sleeping habits, bed size, comfort preferences, and lifestyle. Use the guide below to weigh whether a king size pillow is the right fit for your needs.
Switch to King Size Pillows If You…
- Sleep on a King or California King Bed
These pillows are made to match the width of larger mattresses. Two king pillows side by side will span the bed perfectly, offering better coverage and visual symmetry. - Move Around a Lot While Sleeping
Toss-and-turners and combination sleepers often find standard pillows limiting. King pillows offer extra space so your head doesn’t slip off mid-turn, allowing more freedom without losing support. - Prefer Full-Body or Extra Support
Whether you like to tuck a pillow between your knees, under your arm, or cuddle one as a side sleeper, the length of a king size pillow can function almost like a mini body pillow. - Sit Up in Bed Frequently
Love reading, watching TV, or working on your laptop in bed? A king pillow provides excellent back and shoulder support when propped up vertically. - Enjoy a Luxury, Hotel-Like Aesthetic
If you’re after that plush, polished look, nothing completes a large bed quite like king size pillows in matching shams or pillowcases. They help elevate the entire feel of the room.
You Might Skip the Switch If You…
- Have a Queen, Full, or Twin Bed
King pillows can visually overwhelm smaller mattresses, disrupt sleep alignment, or simply take up too much space—especially if you use more than one. - Sleep Still or Prefer a Compact Pillow
If you barely move at night or prefer a snug, cradled pillow experience, a king pillow may feel too large and impersonal. - Travel or Rearrange Bedding Often
Due to their size, king pillows are less convenient for travel, storing, or changing regularly. If portability and simplicity matter, a smaller pillow may be better. - Are On a Tight Budget
Between the pillow itself and the need for king-sized pillowcases, upgrading might not be cost-effective if you’re trying to keep expenses low.
Quick Decision Checklist
Ask yourself the following:
- Do I sleep on a king or California king bed?
- Do I need more room on my pillow while I sleep?
- Do I want a more supportive pillow for sitting up or lounging?
- Do I value bedroom aesthetics and a luxury look?
- Am I okay with buying king-sized pillowcases separately?
If you answered “yes” to most of the above, a king size pillow could be a worthwhile upgrade!

Frequently Asked Questions(FAQs)
What are the dimensions of a king size pillow?
A standard king size pillow measures 20 inches by 36 inches. This makes it 6 inches longer than a queen pillow and 10 inches longer than a standard pillow, offering extra surface area for comfort and support.
Can I use king size pillows on a queen bed?
Technically yes, but it may not be ideal. King pillows can look oversized and may hang off the sides of a queen bed, making your sleep setup feel cramped. If you like the extra length or want them for lounging, it can work, but for aesthetics and balance, queen pillows are a better fit.
Do king size pillows fit in standard pillowcases?
No. King size pillows require king-sized pillowcases, which are typically around 20 x 40 inches to accommodate the pillow’s full length. Standard or queen pillowcases will be too short and may not close properly.
Are king size pillows good for side sleepers?
Yes! Many side sleepers prefer king size pillows because the extra width provides better support for the neck and shoulders, especially when turning from one side to the other. Some even use them as a partial body pillow.
What’s the best fill material for a king size pillow?
That depends on your sleep preferences. Memory foam and latex offer great support and pressure relief, while down and down alternatives provide softness and luxury. If you’re unsure, adjustable pillows with shredded foam are a popular and versatile choice.
How many king pillows do I need for a king bed?
For both comfort and symmetry, two king pillows are usually ideal for a king bed. You can also layer standard pillows or decorative cushions in front for added depth and style.
Are king size pillows machine washable?
It depends on the fill. Down and fiberfill pillows are often machine washable, while solid memory foam typically needs to be spot cleaned. Always check the care label, and if machine washing is allowed, use a large-capacity washer and dryer for best results.
Conclusion
Choosing the right pillow plays a crucial role in how well you sleep and how comfortable your bed feels. If you’ve been wondering whether to switch to king size pillows, the extra length and surface area they offer can make a noticeable difference—especially if you sleep on a king or California king bed, move around during the night, or want better neck and shoulder support.
That said, king size pillows aren’t for everyone. If you have a smaller bed, prefer a more compact pillow, or are on a tight budget, sticking with standard or queen pillows might be a smarter choice. It’s important to consider your specific sleep habits and bedroom setup before making the switch.
Ultimately, upgrading to king size pillows can elevate both your sleep quality and bedroom style. By choosing the right pillow that fits your needs and investing in quality pillowcases, you’ll enjoy added comfort, support, and a polished look that completes your bedding ensemble.
