When shopping for a new bed, one of the most common questions is: what’s the difference between a California King bed vs King bed? Both are large, luxurious choices, but their dimensions, mattress sizes, and best uses vary. This guide from Bel Furniture explains California King vs King dimensions so you can confidently pick the right size for your bedroom.

Cal King vs King: What’s the Difference?

Before we dive into the specifics, let's uncover the interesting history and dimensions of the California King bed. The California king-size bed was first developed in the mid-20th century, specifically in the 1960s, in response to the growing demand for a longer mattress and taller individuals who prefer extra legroom. The California King size bed is distinct from the standard Eastern King (or King size) bed in that it is longer and slightly narrower. A standard King bed measures 76 inches in width and 80 inches in length, while a California King bed measures 72 inches in width and 84 inches in length. The California king-size bed gained popularity primarily in the Western United States, particularly California. Its longer length was well-suited for people who were taller than average. Over time, its popularity has expanded beyond California and can be found in bedrooms across the United States and other countries.

What Is a California King Bed?

A California King bed (also called Cal King or King Cal mattress size) measures 72 inches wide by 84 inches long. It’s designed with extra length, making it perfect for:

  • Taller sleepers who need more legroom
  • Couples who share the bed with pets at the foot
  • Bedrooms with longer layouts

California King size: 72"x84"

The California King bed measures 72 inches in width and 84 inches in length. It is 4 inches narrower and 4 inches longer than a standard King bed. The extra length makes it an excellent choice for taller individuals who may find their feet hanging off the edge of a standard King bed. 

What Is a Standard King Bed?

A King bed measures 76 inches wide by 80 inches long. It’s wider than a Cal King, making it ideal for:

  • Couples who want maximum width

  • Families who co-sleep with children

  • Square-shaped bedrooms that can fit extra width

King size: 76"x80"

The standard King bed measures 76 inches in width and 80 inches in length. It's a spacious option, providing plenty of room for couples and even families who love to share their bed with kids or pets.

Bed Size Width (inches) Length (inches) Best For
King Bed 76" 80" Couples, families, wider rooms
California King Bed (Cal King) 72" 84" Tall people, couples with pets, longer rooms

California King Bed vs King Bed: Which One Should You Choose?

Choosing the right bed size is important for your comfort, well-being, room aesthetics, and practicality. It's a decision that should be made considering various factors and individual needs to ensure that your bed enhances your overall sleep quality and bedroom experience.

  • Choose a King Bed if you want maximum width for more elbow room or co-sleeping.

  • Choose a California King Bed if you’re tall, share the bed with pets, or prefer the sleek look of a longer mattress.

When it comes down to King vs California King size, both offer spacious comfort — the choice depends on whether you value width or length more.

Pros and Cons of California King Beds

Pros:

  • Ideal for Tall Individuals: The extra length of the California King prevents your feet from dangling off the edge, providing an elongated sleeping surface for those who appreciate more room.

Cons:

  • Slightly narrower in width, which might feel snug for some couples.

  • Bedding may be less common and slightly pricier due to unique dimensions.

Pros and Cons of King Beds

Pros:

  • A wider sleeping area that offers ample space for your family to sleep comfortably.

  • Easier to find standard bedding, making customization convenient.

Cons:

  • Size: While a king bed is larger than a queen bed, it is not as long as a California king. This can be a drawback if you or your partner are tall, as your feet may hang off the end of the bed.

  • Space: King beds can take up a significant amount of floor space in your bedroom. This can be problematic in smaller rooms, leaving less room for other furniture or walking space.

Choosing Between California King and King Beds: A Step-by-Step Guide

Choosing between a California King bed and a King bed or mattress can be a challenging decision, but understanding your specific needs and preferences can make the process easier. Here's a step-by-step guide to help you decide your right bed size:

1. Measure Your Bedroom:

Room size: To measure your room for a California King or King bed, gather tools like measuring tape. Measure the length and width of your room, accounting for any existing furniture. Ensure you have at least 2 feet of clearance on all sides of the bed for easy movement.

Furniture: Consider your existing furniture, such as chest, dressers, nightstands, chairs, vanities, and other items. Ensure there is enough space to fit these pieces alongside your chosen bed without overcrowding the room.

Doors: Take into account the location of windows and doors in your room. Ensure that the placement of the bed doesn't obstruct them or interfere with their functionality.

Measure room size

2. Consider Your Height:

Your height is a crucial factor when deciding between a King and California King bed. Taller individuals, especially those over 6 feet 4 inches (over 6'4"), often face discomfort on a standard King bed, where their feet might hang off the mattress.  A bed that suits your full height allows for a natural sleeping position, reducing the risk of aches and pains. The California King bed, with its extra length, is ideal for taller individuals, providing more legroom and promoting better sleep. 

Consider your height for choosing between California King or King

3. Sleeping Position and Family Needs:

Consider your sleeping habits and whether you have children or pets who share the bed. If you or your partner are side-sleepers or prefer more width to stretch out, a King bed might be preferable. On the other hand, if you sleep flat on your back or stomach with your legs outstretched, the added length of a California King bed can provide the necessary leg space. Families with children or pets can also benefit from the extra width of a King bed.

Consider your family to choose right bed size

4. Mattress Dimensions: King vs California King

Here are the mattress sizes you’ll need to know:

  • California King Mattress Size (King Cal Mattress Size): 72” W x 84” L

  • California King Bed Dimensions (with frame): ~74”–76” W x 86”–88” L

  • Standard King Mattress Size: 76” W x 80” L

  • King Bed Dimensions (with frame): ~78”–80” W x 82”–84” L

Ensure your mattress size aligns perfectly with the bed frame, especially if you're buying them separately. Coordinate with the retailer or manufacturer to confirm that your chosen mattress size matches the California King bed frame you've selected. 

5. Mattress foundation and bedding accessories:

When considering California King or King beds, it's important to acknowledge their relative rarity and potential difficulty in finding a complete bedroom set for this size. Therefore, it becomes vital to turn to a large and diverse retailer like Bel Furniture that offers a comprehensive selection of bedroom sets tailored to your preferred size and style.

King-sized bedding and accessories, including box springs, adjustable bases, sheets, blankets, and comforters, are more widely available and cost-effective compared to California King options. Additionally, King-sized bed frames and adjustable bases are easier to source. If you choose a California King bed, it's crucial to select a reputable, large furniture retailer like Bel Furniture, capable of offering a comprehensive range of California King-sized items, including beds, mattresses, foundations, mattress protectors, and adjustable bases.

Frequently Asked Questions

Is California King bigger than King?

No. A California King is narrower but longer than a standard King. King: 76" x 80". California King: 72" x 84". Cal King offers extra length; King offers extra width.

How do I know if my room can accommodate a California King or King bed?

Measure room length and width, note existing furniture, and keep at least 24 inches of clearance on all sides of the bed for easy movement. Check doorways, halls, and tight corners to ensure delivery and placement are possible. Longer rooms tend to suit California Kings; wider rooms favor Kings.

Which is better: King or California King?

Choose based on height, room dimensions, and sleep habits. A King is better for couples or families who want more space side-to-side. A California King suits taller sleepers or long, narrow rooms by adding extra legroom.

Should I use two Twin box springs to support a king-size mattress?

Use two Twin XL box springs (each 38" x 80") for a standard King mattress (76" x 80"). Twin XL foundations match the King’s length and provide proper edge-to-edge support.

Why buy two Twin XL foundations for a King? Is a single King foundation available?

Two Twin XL foundations are common because they’re easier to move, fit through stairways, and provide stable support. Single-piece King foundations exist but are less common. For a California King (72" x 84"), use two split Cal King foundations, typically 36" x 84" each.

Are there specific bed frames or bases for King and California King?

Yes. Frames and adjustable bases are size-specific. Always match the frame or base to your mattress size for a safe, proper fit.

Is there a price difference between California King and King bedding and accessories?

California King bedding is often less common and may cost slightly more than King sizes. Bel Furniture offers competitive pricing across both sizes, including mattresses, foundations, adjustable bases, and protectors.

Can I put a California King mattress on a King bed frame, or vice versa?

No. The dimensions differ (King 76" x 80" vs. California King 72" x 84"), so mixing sizes leads to overhangs or gaps and can cause stability and comfort issues.

Can I use regular sheets and bedding with a California King or King bed?

No. Use bedding sized specifically for your mattress (California King or King) to ensure proper fit and comfort.

Are adjustable bases available for a California King mattress?

Yes. California King adjustable bases and foundations are available; choose models that specify California King compatibility.

Should I use a box spring for my California King memory foam mattress?

Generally, memory foam performs best on a solid, flat, supportive surface: a platform bed, a slatted frame with slats no more than 3 inches apart, a bunkie board, or a firm foundation. A traditional box spring is usually not recommended unless the manufacturer approves it.

Where is the best place to buy California King beds and mattresses in Houston?

Bel Furniture is a top choice in Texas for California King beds and mattresses, offering a wide selection at affordable prices from brands such as Bel-Opedic, Restonic, Sealy, Spring Air, Kingsdown, and Sierra, plus matching foundations and adjustable bases.

What does 'King Cal' mattress size mean?

It’s another way to refer to a California King mattress, which measures 72 inches wide by 84 inches long.

What is the difference between a California King bed vs. King bed?

A California King measures 72" x 84" (longer, narrower). A standard King measures 76" x 80" (wider, shorter). Choose based on height and room shape.
