Choosing the right mattress size can be puzzling, especially when you’re unsure about the differences between popular options like queen and king. If you’ve wondered, “Is a queen-size mattress bigger than a king?” you’ve come to the right place. Whether you’re a homeowner planning your bedroom layout, an interior decorator advising clients, or someone shopping for the perfect mattress, this guide will help you understand the differences and make an informed choice.
Mattress Dimensions at a Glance
Before we compare queen and king sizes directly, let’s look at their dimensions for an easy side-by-side comparison.
Queen Size Mattress
- Dimensions: 60 inches wide by 80 inches long
- Surface Area: 4,800 square inches
- Ideal For:
- Couples who don’t need extra elbow room.
- Individuals who like to stretch out but have smaller bedrooms.
- Smaller master bedrooms or guest rooms.
King Size Mattress
- Dimensions: 76 inches wide by 80 inches long
- Surface Area: 6,080 square inches
- Ideal For:
- Couples who prefer more personal space while sleeping.
- Parents sharing the bed with kids or pets.
- Large master bedrooms with ample floor space.

A king-size mattress is larger than a queen in width and overall surface area, offering significantly more sleeping space. But your decision should involve more than just numbers. Read on as we explore each mattress size’s benefits, drawbacks, and considerations.
Which Mattress is Bigger? (And Why It Matters)
While a king-size mattress is objectively larger, choosing between a queen and a king involves more than just square inches. Let’s break it down further.
Space Considerations
- Queen: Perfect for rooms at least 10 x 10 feet, making it an excellent fit for smaller layouts or budget-conscious buyers.
- King: Requires a larger room, usually 13 x 13 feet or bigger, to ensure it doesn’t overpower the space.
Rule of thumb: If your bedroom feels cramped with additional furniture like wardrobes, nightstands, and dressers, a queen might be the better fit. However, if your space allows, a king will feel luxurious.
Sleeping Comfort
Couples often find that a queen mattress offers enough room, but a king-size mattress provides more breathing room for those prioritizing personal space.
- Couples on a Queen:
Each person gets 30 inches of width, about the same as a twin bed.

- Couples on a King:
Each person gets 38 inches of width, offering significantly more space to stretch or roll over without inadvertently elbowing your partner.
Pro tip: If you sleep with kids or pets joining the fray, the extra width of a king mattress can be a game changer.
Budget Differences
- Queens are generally more affordable and have lower price tags for mattresses and accessories like bed frames and bedding.
- Kings tend to be pricier due to the added material and size.
To give you a ballpark, a high-quality queen mattress might cost around $800 to $1,500, while a king-sized version of the same model can range between $1,200 and $2,500 or more. Remember that the cost of sheets, a bigger frame, and other accessories will also rise with the size.
Queen vs. King for Bedroom Decor and Functionality
Choosing the right mattress size also affects how your bedroom looks and functions. Here are some additional factors to weigh:
Bedroom Design and Flow
- Queen: Leaves room for extra furniture, such as a reading chair or a bench, and allows better flow in smaller bedrooms.
- King: Can act as the centrepiece of a spacious main bedroom. However, it may limit flexibility when adding accent furniture.

Aesthetic Preferences
While both sizes work with most interior design styles, a king-size bed might feel excessive in a minimalist or cosy design concept. On the other hand, a queen-size bed offers balance without dominating the room.
Is One Better for Healthy Sleep?
Your choice of mattress size can also influence your sleep quality, particularly if you’re prone to tossing and turning or prioritizing specific health needs.
Restless Sleepers
Restless sleepers often find the extra width of a king mattress more comfortable, as it provides ample room to move without disrupting a partner.
Back Support
Both queen and king mattresses can offer excellent back support when paired with a high-quality mattress designed for your sleep preferences (e.g., firm, plush, or hybrid). Your body type and sleeping style (side, back, or stomach) matter more than the size in this scenario.

Bed Size and Room Space
When considering bed size, it’s essential to consider the space in your bedroom. While a king-sized mattress may offer more room for spreading out and comfort, it may not be practical if you have limited space. In this case, a queen mattress could be a better fit. Before deciding, take measurements of your room and ensure enough space for other furniture and walking room around the bed.
Cost Considerations
Another factor to keep in mind when choosing between a queen or king mattress is cost. Generally, king mattresses are more expensive than queen mattresses due to their larger size and materials used. However, not all brands price their beds the same, so comparing prices and features is essential before deciding. Remember that investing in a quality mattress can improve your sleep and overall health, so consider it an investment rather than just an expense.
Personal Preference
Ultimately, choosing between a queen or king mattress will come down to personal preference. Some people may prioritize space and opt for a king-size bed even if they are sleeping alone. Others may value cost savings and choose a queen-sized bed even if they have enough space for a larger bed. It’s essential to assess your needs and preferences when making this decision.
When to Choose a Queen Mattress
A queen-size mattress may be your best bet if:
- Space in your room is limited.
- You’re on a tighter budget.
- Your preferences lean towards a cosier sleeping arrangement.
When to Choose a King Mattress
Opt for a king-size mattress if:
- You have ample room to accommodate it.
- You or your partner desire extra sleeping space.
- You often share the bed with children or pets.
- You prefer a more spacious sleeping area.
Additional Factors to Consider
Aside from personal needs and preferences, there are other factors to consider when choosing between a queen and king mattress.
Cost
Due to their smaller size, queen mattresses are generally less expensive than king mattresses. If budget is a concern, it may make sense to choose a queen mattress.
Room Size
The size of your bedroom should also be considered when deciding between a queen-size mattress and a king-size mattress. A king-size mattress may overwhelm a small room, making it feel cramped and cluttered. On the other hand, if you have ample space in your bedroom, a king-size bed can add an elegant touch and create a more luxurious sleeping experience. Measuring your bedroom and considering the layout is essential before deciding on mattress size.
Sleeping Habits
Another factor to consider is your sleeping habits. Do you tend to move around a lot during the night? A king-size mattress may give you more freedom of movement without disturbing your partner. However, a queen-size bed may be more suitable if you prefer cuddling close to your loved one while you sleep.
Accessibility
The size of your bedroom doors and hallways should also be considered when choosing between a queen-size mattress and a king-size mattress. A king-size mattress can be challenging to manoeuvre through tight spaces, so if you have narrow doorways or hallways, a queen-size bed may be the more accessible option. This is also something to keep in mind if you plan on moving in the future.
Cost
In general, king-size mattresses tend to cost more than queen-size mattresses due to their larger size and materials used. If budget is a concern, a queen mattress may be the more practical choice. However, it’s essential to consider the long-term benefits of investing in a high-quality mattress that suits your needs for a good night’s sleep.
Personal Preference
Ultimately, choosing between a queen or king mattress depends on personal preference. It’s essential to take some time to think about your sleeping habits and choices to make the best decision.
Consider your preferred sleeping position, body size and weight, and potential sleep issues like back pain or allergies. For example, if you move around a lot in your sleep or share a bed with a partner, a king-size mattress may provide more space to comfortably sleep without disturbing each other.
Consider Your Bedroom Size
Another factor to consider when choosing between a queen or king mattress is the size of your bedroom. A king mattress can take up significantly more space than a queen, so measuring your room and ensuring enough space for other furniture and movement around the bed is essential.
Final Thoughts on Choosing Queen vs. King Size
While a king mattress is larger than a queen, both sizes have advantages depending on your specific needs. Here’s a quick recap:
- Pick a queen if You have limited space or budget but still want enough room for two people to sleep comfortably.
- Pick a king if you want extra room, have a spacious main bedroom, or want that added luxury.
Choosing a mattress is about more than just size. Quality, materials, support, and style all contribute to a good night’s sleep.
