If you love catching zzz's on a California king bed, you need the perfect set of sheets to go along with your extra-large mattress. We've spent years researching sheets from the top bedding brands, evaluating softness, durability, fit, and value.
Our top pick, the West Elm European Flax Linen Sheet Set, is made from moisture-wicking Belgian flax linen, has a vintage look, and comes in 19 color and pattern choices.
Here are the best California king sheets available online.
Best Linen: West Elm European Flax Linen Sheet Set & Pillowcases
Linen, made from the fibers of the flax plant, is a great choice for hot sleepers. The fabric absorbs moisture better than cotton, keeping you cool and dry all night long. But not all linen sheets are created equal; some can be itchy and stiff. This West Elm offering is our pick for the best California king linen sheet set: it consists of 100 percent Belgian flax linen, offering a soft and breathable feel. The sheet set includes a fitted and a flat sheet (pillowcases sold separately) and comes in slate, white, platinum and natural colors—all of which have a vintage, French provincial look. While linen is a great choice for humid weather, it also keeps you warm in the winter by acting as a natural insulator.
Whether you’re looking to upgrade your old cotton sheets and splurge on a new set or you want to try a new fabric like flannel or linen, a well-made set of sheets is just what you need to take your California king to the next level.
Best High Thread Count: Andover Mills 1000-Thread Count 100% Cotton Sheet Set
If you’re confused by thread counts (so are we!), it basically refers to the number of horizontal and vertical threads in every square inch of fabric. As you move up in thread count, the sheets get softer and more durable. While a super high thread count may not be for everyone (they’re not as crisp as mid-range counts), they’re often considered the ultimate in bedroom luxury. With a thread count of 1000, the Andover Mills Froehlich 100% Cotton Sheet Set is one of the most luxurious options on this list. These sheets are lightweight, breathable, and perfect for all seasons.
The sheet set includes a fitted sheet with a 16-inch pocket, a flat sheet, and two pillowcases, and it’s wrinkle-resistant and machine washable. Choose from 16 colors, including classic white.
Best Sateen: Mayfair Linen 100% Egyptian Cotton Sheet Set
Sateen sheets have a silky, luxurious feel, but they’re typically heavier and warmer than a percale weave. If you’re looking for a durable sateen sheet, we love the Mayfair Linen Bedding Collection Sateen Weave Sheets. These 100 percent Egyptian cotton sheets look like a million bucks but cost far less. They come in eight colors and fit mattresses up to 15 inches deep. Sateen sheets are more prone to slippage, so ensuring a perfect fit on your mattress is key to keeping them in place.
These sheets are breathable and don’t snag easily, both of which are important when picking a set of sateen sheets. They’re also resistant to wrinkles and have a slight sheen to them that makes them look more expensive than they actually are.
Best Flannel: Pinzon 160 Gram Plaid Flannel Sheet Set
On chilly nights, make your bed super cozy with these Pinzon 160 Gram Plaid Flannel Sheets. Made from 100 percent OEKO-TEX certified cotton, the 160-gram sheets are durable, soft, and breathable. The sheets also feature a napped finish on each side to make them feel velvety soft and comfortable. We love the classic plaid design, too, and you can choose from five colors that will instantly make your bedroom feel warm and inviting.
The California king sheet set includes a fitted sheet with a 16-inch pocket, a flat sheet, and two pillowcases. Switching your sheets to flannel for the winter is a great way to save on heating bills while staying warm and cozy every night, and this set is soft and snuggly.
Best Wrinkle-Free: Royal Hotel 650-Thread Count Wrinkle-Free Sheets
Let’s be honest: Nobody has time to iron sheets, but that doesn’t mean you have to settle for a messy bed. If you want your guest room (or your own bedroom) to look polished and pulled-together without a lot of effort, the Royal Hotel California-King Wrinkle-Free Sheets will save you a good deal of time and energy. These 650 thread-count, 70 percent cotton and 30 percent polyester sheets are specially formulated to resist wrinkles. They’re available in 16 colors (we’re partial to the gray or white) and fit mattresses up to 18 inches. Like most sheet sets on our list, each one comes with two king-sized pillowcases along with a flat and a fitted sheet. These sheets are sateen weave, but they don’t feel overly silky or smooth.
These sheets rarely wrinkle, even when they sit in a heap after they’ve been washed (it’s okay, we do it too). A set of wrinkle-free sheets is the easiest way to keep your bedroom looking clean with only a modicum of effort.
Best Deep Pocket: Southshore Fine Linens 21 Inch Extra Deep Pocket Sheet Set
If you appreciate the softer things in life, you probably own a pillow top mattress. A plush mattress is a great investment, but you’ll need sheets with deep pockets to adequately tuck it in. Good news: The Southshore Fine Linens 21" Deep Pocket Set is one of the best-priced deep pocket sheets you can buy. With 21 inches to work with, even the thickest pillow top mattresses will have plenty of coverage. The sheets are available in 18 subtle and classy colors, and each set includes six pieces: a flat and fitted sheet and four oversized pillowcases. The sheets are made from double-brushed microfiber, which has the added bonus of making them a little more budget-friendly.
You'll love these sheets’ softness, which compares to the feel of an 800 thread count sheet. These sheets are durable, plush, and fit even the most luxurious of pillow top mattresses.
Best High-End: Wamsutta Dream Zone 1000-Thread-Count PimaCott Sheet Set
Since we spend so much of our lives in bed (one-third to be exact), we may as well do it right. The Wamsutta Dream Zone 1000-Thread-Count PimaCott Sheet Set is the ultimate in luxury—and though it comes at a higher price point than any of the other sheets on our list, it’s worth it if you’re looking for a product that will last a lifetime. These 1000 thread count sheets are made from 100 percent pima cotton, a type of cotton that uses extra-long, dense fibers for a softer feel and longer-lasting construction. The sheets fit mattresses up to 20 inches deep, and the pillowcases (sold separately) come in standard or king-sized. The sheets are available in 15 muted, modern colors, including one striped white version we particularly like.
The Wamsutta Dream Zone PimaCott sheets are highly luxurious, with just the right amount of shimmer. If you want to splurge on a durable and cozy set of sheets for your California king, the Wamsutta Dream Zone PimaCott is a great choice.
For soft, breathable comfort, the Belgian Flax Linen Sheet Set is our top choice because it's temperature-regulating and has a lived-in look that's effortlessly chic. And if you love low-maintenance sheets, the Royal Hotel Wrinkle-Free Sheets (view at Amazon) are made from a cotton-polyester blend that's wrinkle-resistant, and they're available in a range of colors.
What to Look for in California King Sheets
When shopping for sheets, be sure to look at the material they’re made from. Cotton sheets are known to be breathable and easy to care for, while flannel sheets are warm and cozy in the winter. Polyester or microfiber sheets are often inexpensive but don’t last as long, and linen sheets are quite pricey but can be used for years if taken care of properly. The best choice depends on your priorities.
Most sheets are made from woven fabric (with the exception being knitted jersey sheets), and the type of weave will affect how the sheets feel, as well as their longevity. A percale weave results in a stronger, more crisp fabric that’s easy to care for, while sateen weaves are a bit softer but more prone to pilling.
As you shop for sheets for your California king bed, pay special attention to the depth of the pocket on the fitted sheet. Many large mattresses are deeper—sometimes 16 inches or more—and you’ll want to ensure your sheets have a pocket that will comfortably accommodate this depth. Otherwise, they may fit poorly and fall off the mattress.
What is the difference between king and California king sheets?
The difference between king and California king sheets comes down to their dimensions. California king beds, in general, are longer than regular king-size beds but almost always narrower, too. King beds need sheets that are 76 inches wide by 80 inches long, whereas a California king bed will require sheets that are 72 inches wide by 84 inches long.
Where can you buy California king sheets?
Shoppers won’t have to go far to find sheets that fit this particular size bed. Most stores and online retailers carry California king sheets now, including popular places such as Amazon, Wayfair, Bed, Bath & Beyond, and West Elm. They are offered in a variety of fabrics as well, like flannel, cotton, and sateen.
How big are California king sheets?
California King sheets measure 72 inches wide and 84 inches long. However, they do vary in depth, so buyers will want to take this mattress measurement into consideration to ensure a good fit and sheets that won’t pop up or slide off. Normally sheets fit mattresses around 15 to 18 inches deep, but there are deep pocket options for mattresses around 20 to 21 inches.
