King vs Queen Bed Measurements: Which Size Fits Your Room and Your Life?

The choice of a king size bed versus a queen size bed can make a noticeable difference to your bedroom layout and sleeping space. In Australia, a standard queen mattress measures 153 cm wide × 203 cm long, while a king mattress measures 183 cm wide × 203 cm long. The main difference is width: a king gives you an extra 30 cm of space without taking up more length.

So, is a king bed worth the extra room, or will a queen suit your lifestyle better? The answer depends on how you sleep, who shares your bed and how much floor space you have available. This guide compares king bed versus queen dimensions, explains the practical differences behind the queen bed vs king bed choice and helps you choose a size that works for your home.

King Bed vs Queen Bed: Comparing the Dimensions

The easiest way to understand the difference between a king and queen bed is to compare their mattress measurements. Both are popular choices for Australian bedrooms, but they offer different amounts of sleeping space.

King Size Bed vs Queen: Measurements in Australia

A standard Australian queen mattress measures 153 cm × 203 cm. A king mattress measures 183 cm × 203 cm. Both have the same length, but the king is wider.

That extra width gives a king around 20% more sleeping surface area than a queen, which matters most when two people share the bed, particularly if either sleeper likes to stretch out.

These measurements refer to the mattress itself, not the complete bed frame. A headboard, side rails, footboard or storage base can increase the total floor space required. If you are also checking frame clearance, our guide to king size bed dimensions explains how headboards and side rails can affect the overall footprint.

King vs Queen Bed Width and Length: What's the Difference?

When comparing king size bed width vs queen—or queen bed vs king bed width—the main difference is the extra 30 cm across the mattress. A queen is 153 cm wide, while a king is 183 cm wide. If two people share the bed, that works out to approximately 76.5 cm of width per person on a queen and 91.5 cm on a king, assuming they divide the space evenly.

What about the length of a queen bed vs king? There is no difference. Both mattresses measure 203 cm long, so choosing a king does not give taller sleepers extra length. It simply provides more room from side to side.

If your current queen feels too narrow, a king may give you the extra space you need. However, if the issue is mattress length, moving from a queen to a king will not solve it. Check the measurements of the mattress and the room before deciding.

King vs Queen Bed Dimensions in Inches, CM and Feet

You may come across measurements in centimetres, inches or feet when comparing beds online. The table below converts standard Australian queen and king mattress dimensions into all three units.

Keep in mind that king size vs queen size bed measurements can vary between countries. A US king, for example, is not the same as an Australian king. UK bed sizes also follow a different standard, and a California king has different proportions again.

If you are buying a mattress or bedding from an overseas retailer, do not rely on the size name alone. Check the actual measurements in centimetres to make sure the pieces fit together. If you are matching an imported mattress to a local frame, compare bed frames by their external dimensions as well as the mattress size. For other local mattress sizes, see our guide to bed sizes in Australia.

King Bed Versus Queen: Which Size Is Better for Your Needs?

The right choice is not always the biggest bed available. A king offers more room to move, while a queen can leave more space for other bedroom furniture. Consider how you use your bedroom before choosing between the two.

King Bed vs Queen Bed for Couples

For many couples, a queen bed comfortably accommodates two adults, making it a practical choice when you do not need much extra sleeping space.

With a king, each person gets more room to move. This can be useful if one partner changes position frequently, prefers to spread out or shares the bed with a child or pet. The additional width may also help couples who find a queen mattress feels a little cramped.

Think about your usual sleeping habits. Do you both stay on your own side, or do you often wake up competing for space? If you want more room without increasing the mattress length, a king may be the better option.

Is a Queen or King Bed Better for Small Bedrooms?

In a small or medium-sized bedroom, a queen is often easier to fit. Its narrower footprint leaves more room for bedside tables, wardrobes and walkways. It can also make the space feel less crowded, particularly when the room has built-in storage or limited floor space.

A king needs more width. Before choosing one, consider whether you can still open wardrobe doors, access drawers and walk comfortably around the bed. Remember to account for the frame, not just the mattress.

Door position, windows and wardrobe clearance all affect how much space you need. If a king leaves little room to move, a queen may be the more practical choice.

Who Should Choose a King Bed?

A king bed may suit you if:

• You and your partner want more personal sleeping space.
• One or both sleepers move around frequently during the night.
• Your child or pet sometimes shares the bed.
• You have a spacious main bedroom.
• You prefer a wider mattress and have room for a larger frame.

A king can make a shared sleeping space feel less restricted. It is worth considering if you want more width and your bedroom can comfortably accommodate the larger frame.

Who Should Choose a Queen Bed?

A queen bed may be the better fit if:

• You have a small or medium-sized bedroom.
• You are a single sleeper who wants extra room.
• You and your partner are comfortable sharing a more compact sleeping space.
• You want to leave more floor space for other furniture.
• You prefer a practical balance between sleeping area and bedroom layout.

A queen is also worth considering if you move house regularly. A smaller mattress and frame can be easier to manoeuvre through doorways, hallways and staircases than a king. If you choose a queen, check queen bed frames for their external width and length, since a frame can add several centimetres on each side.

King vs Queen Bed: Which Offers Better Value for Money?

The value of a king or queen bed depends on more than the initial purchase price. A king mattress and frame may cost more than their queen equivalents, and larger bedding can also affect your overall budget.

Consider the full setup before making a decision. You may need a new mattress, bed frame, fitted sheets, mattress protector and quilt cover. Check the cost and availability of these items in your preferred size.

A queen may offer better value if you do not need the additional width. However, if a king gives you the sleeping space you want and fits your bedroom, the extra cost may be worthwhile. The best option is the one that meets your needs without stretching your budget unnecessarily.

King vs Queen vs Other Bed Sizes: How Do They Compare?

King and queen are not the only options available in Australia. Double, king single and super king mattresses serve different needs, while California king and Alaskan king are less common overseas sizes. Comparing them can help you decide whether a queen or king is the right step up for your bedroom.

Double vs Queen vs King Bed: What Is the Difference?

A double mattress measures 138 cm × 188 cm in Australia. A queen measures 153 cm × 203 cm, while a king measures 183 cm × 203 cm.

A double is narrower and shorter than a queen, so it may suit a single adult or a guest bedroom where space is limited. A queen provides more room for two sleepers and is a common choice for main bedrooms. A king adds another 30 cm of width, making it a useful option for couples who want more personal space.

If you are considering a double as an alternative, our double bed size guide explains its measurements and typical uses.

California King Size Bed vs Queen Size Bed

California king is a bed size associated with the US market. It is generally longer and narrower than a standard US king, rather than simply being a larger version of an Australian king.

When comparing a California king size bed vs queen size bed, check the exact dimensions of both mattresses. International sizing names can be confusing, and a California king should not be assumed to match an Australian king. Availability can also be limited in Australia.

If you are particularly tall, mattress length may be an important factor in your decision. However, a standard Australian king and queen are both 203 cm long. Check the measurements of any imported mattress and its matching frame before purchasing.

Queen Bed vs Super King: Which One Offers More Space?

A super king is larger than a standard king. A commonly used Australian super king mattress measurement is approximately 203 cm × 203 cm, compared with 153 cm × 203 cm for a queen.

The extra width makes a super king an option for people who want a particularly spacious sleeping surface. It may suit couples who share their bed with children or pets, or anyone with a large bedroom and room for a wider frame.

However, a super king needs more floor space and matching bedding. If your bedroom cannot accommodate the larger footprint comfortably, a standard king may provide a more practical balance.

King Single Bed Size vs Queen: Which Should You Choose?

A king single mattress measures 107 cm × 203 cm, while a queen measures 153 cm × 203 cm. Both share the same length, but a queen is 46 cm wider.

A king single is designed primarily for one person. It can suit teenagers, taller children and adults who want more room than a standard single without moving to a double or queen. A queen gives a solo sleeper even more space and can also accommodate two adults.

Your available floor space is an important consideration. If you are furnishing a teenager's room or a guest room, a king single may be a sensible choice. Compare king single bed frames by their external dimensions before deciding whether the extra width suits the room.

Alaskan King Bed vs Queen: How Much Bigger Is It?

An Alaskan king is an oversized mattress associated with the US market. It is considerably larger than a standard queen and is designed for bedrooms with plenty of available space.

Unlike common Australian mattress sizes, an Alaskan king is not a standard option in most local bedroom setups. Finding a matching mattress, frame and bedding may require specialist or custom ordering.

Full vs Queen vs King Bed: What Is the Difference?

Full is a mattress size used in the US. It is similar to an Australian double, but the measurements are not exactly the same. A US full mattress is generally around 137 cm × 191 cm, while an Australian double measures 138 cm × 188 cm.

A queen provides more width and length than a full or Australian double. A king adds another 30 cm of width over an Australian queen while keeping the same length.

How to Choose Between a King and Queen Bed in Australia

Once you understand the size difference, the next step is to work out which bed will suit your home. Think about the room layout, the frame design and the cost of replacing your bedding.

Measure Your Bedroom Before Choosing a Bed

Start by measuring the length and width of your bedroom. Then check the external dimensions of the bed frame you are considering. The mattress measurements alone will not tell you how much floor space the complete bed will occupy.

Allow enough room to walk around the bed and access nearby furniture. Consider the space needed for bedside tables, wardrobes, drawers and doors. If your room has an unusual layout, sketching the furniture positions can help you visualise how a king or queen will fit.

Do not forget the route into the bedroom. Measure doorways, hallways and staircases, and consider any tight turns or lifts. A larger bed frame may be difficult to move into a room even when the bedroom itself has enough space.

Consider Your Mattress and Bed Frame Sizes

Your mattress and bed frame need to be compatible. A queen mattress requires a queen frame, while a king mattress needs a king frame. Check the product specifications carefully, particularly if you are replacing only one part of your existing bed setup.

The frame's external dimensions may be larger than the mattress. A padded headboard, thick side rails or a footboard can add to its overall footprint. Storage designs may also need extra clearance, depending on how the drawers open.

Think about the style and function you want. A simple frame may suit a compact room, while a storage design can provide a useful place to keep spare bedding and other items.

Think About Bedding and Replacement Costs

A larger mattress needs correctly sized bedding. Queen and king fitted sheets are not interchangeable, and your mattress protector should match the mattress dimensions. Check the quilt cover and other bedding measurements too, especially if you are buying a complete new set.

The cost of replacing these items should be part of your decision. King bedding may have different prices and a different range of styles from queen bedding. It is worth checking availability before committing to a larger mattress.

Also consider future moves and replacements. A king mattress can take up more space during transport and may need more planning when moving through a property. If you expect to move soon, think about whether the larger size will suit your next bedroom as well.

Final Verdict: Is a King or Queen Bed Right for You?

There is no universal winner in the king bed vs queen bed comparison. The right size depends on how much sleeping space you want and how comfortably the bed fits into your room.

If your bedroom has enough room and you want more space to share, a king may be worth considering. If you prefer a practical layout with room for other furniture, a queen may be the better fit.
