Know Everything About King Size Bed Frame Measurements

A queen size bed can be comfy for many couples, but over time it might not be enough. If your kids often join you in bed or your partner moves around a lot while sleeping a king-size bed can give you both more space for a better night’s sleep. When you choose to buy a king-size mattress, you will probably need a new bed frame too. A sturdy bed frame is important because it supports the mattress and helps it last longer. It can also set the style for a bigger room. We created this king bed frame size guide to help you pick the right size and style for your bedroom.

King Size Bed Frame Measurements

A standard king-size mattress, also known as an “eastern king,” is 76 inches wide and 80 inches long, giving each person 38 inches of space. King-size bed frames are usually about a half-inch to 2 inches wider and longer than the mattress. So, most king-size bed frames, including California king bed frames, are between 76.5 to 78 inches wide and 80.5 to 82 inches long. These sizes might change a bit based on the frame type.

A King-size headboard will be slightly wider than the bed frame, measuring between 79 to 81 inches wide. The height of the headboard can vary from 48 to 64 inches.

Variations of King-Size Bed Frames

Four Poster Bed Frames

Four-poster bed frames have four tall pillars at each corner of the bed. For a king-size four-poster bed, these pillars are usually about 80 inches high. These frames are often made of metal or wood and feature a decorative headboard and footboard.

Sleigh Beds

Sleigh beds are made of wood and have a headboard and footboard that resemble a horse-drawn sleigh. These frames often have decoratively curved or scrolled woodwork on the frame and a slatted foundation to support the mattress. In the master bedroom, a sleigh bed creates an exciting and dramatic centerpiece.

Panel Frames

Panel frames are a common and easy-to-find option. They include two side panels, a headboard, and a footboard. The base of a panel frame is made from wood or metal slats that support the mattress and, if needed, a foundation.

Adjustable Frames

Adjustable bed frames let sleepers raise their head and legs during sleep. Elevating the head opens up the airways, making breathing easier and reducing snoring and sleep apnea symptoms. Raising the legs improves circulation and reduces swelling in the feet and legs.

Canopy Bed Frames

Canopy bed frames are like four-poster beds but with an added feature. They have four tall pillars, a headboard, and a footboard, plus four slats at the top that connect the pillars to form a square shape. You can hang curtains or fabric from the canopy for a decorative look.

Platform Frames

Platform frames are similar to panel frames, but they have a solid wood or slatted foundation. You don’t need an extra foundation with a platform bed. You can place the mattress directly on the base of the frame.

Types of King Size Bed

King-size mattresses come in several types beyond the standard one. You might know about the California king, but have you heard of the Wyoming or Texas king? Keep reading to learn about the sizes of these king variations.

Alaskan King

The Alaskan king bed is the largest mattress available, measuring 108 inches wide by 108 inches long. It’s spacious enough for two adults and 3 to 4 small children to sleep comfortably. An Alaskan king is perfect for families who want to co-sleep without feeling cramped or uncomfortable.

California King Bed

The California king mattress is the most popular king-size variation and is easy to find with most online brands. First introduced in Los Angeles in the 1960s, you might also see it called a “Western king.” A California king mattress is 72 inches wide and 84 inches long—4 inches narrower but 4 inches longer than a standard king mattress. This extra length provides more legroom, making it a great choice for taller people.

Texas King

A Texas Kung, also known as a “grand king”, measures 80 inches wide by 98 inches long. It is 4 inches wider and 18 inches longer than a standard king mattress. Compared to a Wyoming king, a Texas king is four inches narrower but fourteen inches longer.

Split King Bed

When it comes to mattress firmness, couples often have different preferences. To meet each person’s needs, many choose a split king-size mattress.

This option is also popular because it can be used with a split adjustable base, which lets each person adjust the head and foot of the bed to find their ideal sleeping position.

A split king mattress is made up of two twin XL mattresses (38 inches wide by 80 inches long) placed side by side to create a standard 76 inches by 80 inches king-size mattress.

You can also use a split king mattress with most modern king-size bed frames if you don’t want an adjustable base.

Wyoming King

A Wyoming king-size mattress is 84 inches wide by 84 inches long. It is the same length as a California king but is 12 inches wider than a Cal king and 8 inches wider than a standard king. A Wyoming king is ideal for families who want to co-sleep with 1 or 2 small children.
