You want to add a Murphy bed to reclaim your space, but you're frozen with indecision. A Queen seems perfect for guests, but will it overwhelm the room? A Twin feels practical, but is it too small for adults? You're worried about making the wrong choice, spending thousands on a bed that either eats up too much space or doesn't meet your needs. This indecision can stop your entire project, leaving you stuck with a cluttered, inefficient room.
Choosing between a Queen, Full, or Twin Murphy bed depends on your available space, how you'll use it, and your budget. A Queen is best for couples or maximizing guest comfort but requires the most room. A Twin is perfect for single guests or kids and uses minimal space, while a Full offers a good compromise for solo sleepers who want extra room. Carefully measure your wall and floor space before deciding which size fits your lifestyle best.
Choosing a Murphy bed size seems simple—you just match it to the mattress size, right? From my five years in this industry, I can tell you there's more to it. As a manufacturer, we see a huge difference between a Twin and a Queen that goes beyond a few inches of width. The real change is in the physics. A Queen mattress adds a lot of weight, which means we have to engineer a much more powerful—and expensive—lift mechanism to make it feel light. This preference for bigger beds puts a lot more stress on the wall anchors, making a perfect installation absolutely critical. To us, a Queen isn't just a bigger bed; it's a higher-risk engineering challenge. Let's look at the real-world factors so you can make a truly informed choice.
How Much Wall and Floor Space Do You Really Need for Each Murphy Bed Size?
You have your tape measure out, but the online specifications are confusing. You see terms like "projection depth" and "cabinet height" and you're not sure how they translate to your actual room. You're worried you'll miscalculate and order a bed that's too big. The last thing you want is to install it, only to find you can't open a nearby door or the bed hits a ceiling fan. It's a stressful and expensive mistake to fix.
To figure out the space you need, you must measure for both the closed cabinet and the open bed. For a standard vertical Queen Murphy bed, you'll need about 65 inches of wall width and clearance for it to project 87 inches into the room when down. A Full needs about 60 inches of width and 82 inches of projection. A Twin requires around 45 inches of width and the same 82-inch projection. Always add a few inches on each side for easier installation and use.
This is the very first thing every customer should do. Before you even think about style or color, you have to confirm the fit. I always tell my clients to use painter's tape to mark both the cabinet's footprint on the wall and the bed's footprint on the floor. This gives you a real-world visual of how the unit will impact your space, both when it's open and when it's closed. It helps you see if you'll still have room to walk around or access other furniture.
Vertical vs. Horizontal: A Key Decision
The orientation of the bed dramatically changes the space it requires.
- Vertical Beds: These are tall and narrow. They use less wall width but project further into the room. This is the classic Murphy bed look and is great for rooms with high ceilings.
- Horizontal Beds: These are short and wide. They use more wall width but don't come out as far from the wall. This is ideal for rooms with low ceilings, like basements, or in narrow spaces where you need a clear walkway.
Don't Forget Projection and Clearance
"Projection" is simply how far the bed comes into the room from the wall when it's open. This is the most commonly forgotten measurement.
- Walking Space: You need to leave at least 24-30 inches of walking space around the foot and side of the open bed. If you don't, the room will feel cramped and unusable.
- Obstacles: Check for ceiling fans, lights, and the swing of closet or room doors. Make sure the open bed won't hit anything.
Real-World Space Requirements
Let's put some hard numbers to these concepts. These are typical dimensions, but always check the exact specs for the model you're buying.
| Bed Size | Typical Vertical Cabinet (W x H) | Typical Projection (Open) | Min. Recommended Walkway |
| Twin | 45" x 87" | ~82 inches | 24 inches |
| Full/Double | 60" x 87" | ~82 inches | 24 inches |
| Queen | 65" x 92" | ~87 inches | 30 inches |
| Horizontal Queen | 86" x 67" | ~65 inches | 30 inches |
Is a Queen Murphy Bed Always the Best Choice for Guests and Couples?
Your gut tells you that to be a good host, you need to offer your guests a Queen bed. It feels like the standard for comfort, especially for couples. But you look at your multi-purpose room and hesitate. A Queen bed, even when folded up, has a large presence. You worry it will make your home office feel more like a bedroom with a desk crammed into the corner. And you know the Queen models are more expensive, making you question if it's truly worth it.
A Queen Murphy bed is not always the best choice. While it offers great comfort, it demands significant space and budget. If your guests are typically solo travelers or if the bed will only be used a few weekends a year, a Full or even a high-quality Twin can be a much more space-efficient and cost-effective solution. The best choice balances guest comfort with your day-to-day need for an open, functional room. It's often better to have a usable office 95% of the time.
This is a classic case of buyer psychology. People default to "bigger is better" without considering the trade-offs. From a manufacturer's view, the jump from Full to Queen is huge. As I mentioned, the Queen's weight requires a more robust and expensive lifting mechanism. This adds hundreds of dollars to the cost. It also puts much more force on the wall. A Full bed provides ample space for most single guests and is perfectly adequate for many couples for a short stay, while saving you space and money.
The Case for a Full-Size Bed
The Full (or Double) bed is the unsung hero of the Murphy bed world.
- "Good Enough" for Couples: For a weekend visit, most couples are perfectly fine in a Full bed. It's cozy.
- Spacious for Singles: It feels luxurious for a single guest, giving them plenty of room to spread out.
- Space Savings: That 5 inches of width you save compared to a Queen can make a real difference in a small room, allowing for a wider desk or more shelving.
When a Queen Is a Must
Of course, there are times when a Queen is the right call.
- Primary Bed: If the Murphy bed will be used every night by a couple, you absolutely should get a Queen for long-term comfort.
- Luxury Guest Experience: If your goal is to create a high-end guest suite and you have the space, a Queen bed sends a clear message of hospitality.
Sizing Up Your Needs: Queen vs. Full
Let's compare them head-to-head to see which makes more sense for you.
| Factor | Queen Murphy Bed | Full Murphy Bed | The Verdict |
| Guest Type | Ideal for couples on longer stays | Great for singles; adequate for couples on short stays | Full is more versatile for varied guests |
| Space Impact | Requires ~5-6 extra inches of wall width | More space-efficient, fits better in smaller rooms | Full wins for maximizing a multi-purpose room |
| Cost | Higher cost due to size and stronger mechanism | More affordable | Full offers a better value for occasional use |
| Mattress | 60" x 80" | 54" x 75" | Queen is the standard for master bedrooms |
Can Twin Murphy Beds Be Combined for Flexible Guest Room Layouts?
You have a guest room that needs to be incredibly flexible. Sometimes you host a single friend, other times it's two kids, and occasionally it's a couple. The idea of installing one big bed feels too rigid. You've wondered if you could use two separate Twin Murphy beds to create a modular space, but you're not sure if it's practical. You worry it would look strange or be difficult to manage, and you fear the "crack" between the beds would be uncomfortable for couples.
Yes, you can absolutely combine two Twin Murphy beds to create a highly flexible guest room. By installing two Twin beds side-by-side, you can use them as separate beds for kids or individual guests. When a couple visits, you can open both beds and use a "bridge" mattress connector and King-size bedding to create a comfortable, unified sleeping surface. This approach offers maximum versatility for a multi-use space.
I love this solution. It's a clever way to solve a common problem. From our side, building two Twin systems is often simpler and safer than one large, heavy King system. Each Twin bed has its own balanced mechanism, making them lightweight and easy for one person to operate. It also spreads the load across a wider section of the wall, which is great from a structural standpoint. It's an elegant engineering solution that also happens to be incredibly practical.
The "Flexible King" Setup
Here’s how you make two Twins work as one King.
- Side-by-Side Installation: The two cabinets are installed directly next to each other. When closed, they can look like a single, large wardrobe unit.
- Mattress Bridge: This is a simple foam insert that you place in the gap between the two mattresses. It creates a smooth, even surface.
- King Bedding: Use a King-size fitted sheet to hold the two mattresses and the bridge together, followed by King-size flat sheets and blankets. The result feels just like a standard King bed.
Advantages of the Dual Twin System
This setup offers benefits you can't get with a single Queen.
- Ultimate Versatility: It's the only solution that works for two separate individuals (like siblings or friends traveling together) and for a couple.
- Lighter Operation: Each Twin bed is significantly lighter and easier to lift than a single Queen bed. This can be a major benefit for daily use.
- Redundancy: If one mechanism ever needs service, you still have another usable bed.
Dual Twin vs. Single Queen
Is this flexible approach right for you? Compare it against the simpler Queen option.
| Feature | Dual Twin Murphy Beds | Single Queen Murphy Bed | The Verdict |
| Flexibility | Highest. Can be two twins or one king | Low. Only works as one bed | Dual Twins win for multi-purpose rooms |
| Cost | Often more expensive (two mechanisms, two cabinets) | Generally more affordable than two Twins | Queen is the more budget-friendly option |
| Installation | More complex. Requires leveling and aligning two cabinets | Simpler. One cabinet to mount | Queen is easier and faster to install |
| Comfort for Couples | Good with a mattress bridge | Excellent. No seam | Queen offers slightly better, seamless comfort |
What Frame Depth and Clearance Should You Plan for When Installing a Murphy Bed?
You're trying to finalize the layout for your room, and you're focused on the bed's footprint on the floor. But you've overlooked a key dimension: the depth of the cabinet itself. You're not sure how far the closed unit will stick out from the wall. You're worried that a bulky cabinet will make the room feel smaller, get in the way of a walkway, or look awkward. This uncertainty makes it hard to visualize the final result and integrate the bed seamlessly into your design.
When planning for a Murphy bed, you should account for a cabinet depth of around 16 to 20 inches. A standard 16-inch depth is common for beds that use a mattress up to 11 inches thick. If you want to use a thicker, more luxurious mattress (12 inches or more), you will need a deeper cabinet, closer to 20 inches. Always confirm the required cabinet depth for the model you choose to ensure it fits your mattress and your room's layout.
This detail is directly tied to a major trend we're seeing in the market: the desire for thicker, plusher mattresses. Ten years ago, everyone used thin 8-inch mattresses. Today, people want to use the same 12-inch premium mattress they have in their master bedroom. From a manufacturing perspective, a deeper mattress requires a deeper cabinet. It's a simple geometric reality. It also adds more weight, again reinforcing the need for a stronger lift system and a rock-solid installation.
Standard Depth vs. Deep Cabinets
Understanding the trade-off here is important.
- Standard Depth (~16 inches): This is the most common and space-saving option. It creates a sleek, low-profile look. It's designed to hold a quality mattress up to about 10 or 11 inches thick.
- Deep Cabinets (~20+ inches): You will need this if you plan to use a very thick pillow-top or memory foam mattress of 12 inches or more. The extra depth is also useful if you want to leave the pillows on the bed when closing it.
Don't Forget the Strap System
Part of the depth equation is the system that holds the mattress and bedding in place.
- Mattress Straps: Every Murphy bed comes with straps (usually elastic or nylon) that buckle over the mattress to hold it in place when the bed is vertical.
-
Bedding Straps:
Many systems also include a strap or bar at the foot of the bed[^1] to hold your comforter and pillows in place. If you plan to leave thick bedding on, this contributes to the total depth needed[^2].
Planning Your Dimensions: A Final Check
Before you buy, run through this quick clearance checklist.
| Dimension | Standard Range | Why It Matters | My Advice |
| Cabinet Depth | 16-20 inches | Affects how much the closed unit intrudes into the room | Go for 16" unless you have a specific thick mattress you must use |
| Mattress Thickness | 8-12 inches | Determines the required cabinet depth | 10-11 inches is the sweet spot for comfort and cabinet compatibility |
| Projection (Open) | 82-92 inches | The total floor space the bed uses when down | Use painter's tape to visualize this on your floor |
| Side Clearance | 2-4 inches | Needed for installation and to avoid scuffing walls | Don't try to fit a 65" bed into a 65" alcove. It won't work |
Conclusion
Choosing the right Murphy bed dimensions is about more than just mattress size; it's a careful balance of your room's layout, your intended use, and the underlying engineering of the bed. While a Queen bed offers maximum comfort, a versatile Full or a clever dual-Twin system can often be a smarter choice for a multi-purpose room. The most important step is to measure your space accurately, accounting for the cabinet, the bed's projection, and clearance. By understanding that a larger bed means a more powerful mechanism and more stress on your wall, you can make a choice that is not only comfortable but also safe and perfectly suited to your home.
