I live in a small city apartment. Space feels tight. I struggle to fit furniture. Clutter stresses me out. A Murphy bed fixes this. It folds into the wall. My room stays open. At my Shopify store, we sell these beds. We use our U.S. warehouse for fast delivery. Murphy beds save space and add style. But picking the right size is key.
Murphy beds come in standard sizes: twin, full, queen, and king. They need specific wall space. Measure height, width, and depth. Mattresses must match the frame. Vertical beds save floor space. Horizontal ones fit low ceilings. The lifting mechanism affects size too. Costs range from $500 to $2,000.

I see customers confused about sizes. They want perfect fits. I help them choose. My five years at Yechen Home Furniture taught me this. We make beds that transform homes. Read on to learn sizing tips. You will find the right bed.
What Are the Standard Sizes for Murphy Beds?
I once bought a bed that didn’t fit. My room felt smaller. Frustration hit hard. Standard sizes prevent this. They match most homes.
Murphy beds come in twin (39x75 inches), full (54x75 inches), queen (60x80 inches), and king (76x80 inches). Each needs specific wall space. Vertical beds need 80-90 inches of height. Horizontal ones need less, about 45-60 inches. Depth is 16-24 inches when folded. Our warehouse stocks all sizes.

I dive into sizing details. The lifting mechanism matters more than you think.
Twin Size Benefits
Twin beds fit small rooms. They’re great for kids or guests. I installed one for a client. It saved space for a desk.
Full Size Versatility
Full beds suit teens or couples. They balance size and space. I recommend them for studios. They’re popular in our store.
Queen and King Options
Queen beds are most common. They fit couples. Kings need big walls. I check space before suggesting these.
Mechanism Impact
The lifting system adds size. Springs or pistons need strong cabinets. This adds depth. I learned this at Yechen. A queen bed’s cabinet can vary by 4 inches based on hardware.
Here’s a size comparison table.
| Size | Bed Dimensions | Wall Space Needed | Best For |
| Best For | 39x75 inches | 80x45 inches | Kids, guests |
| Full | 54x75 inches | 80x60 inches | Teens, studios |
| Queen | 60x80 inches | 85x66 inches | Couples |
| King | 76x80 inches | 85x82 inches | Large rooms |
Sizes guide your choice. I helped a customer pick a queen. It fit perfectly. Wrong sizes waste money. Check your room first.
How to Measure Your Space for a Murphy Bed?
I mismeasured a room once. The bed didn’t fit. I felt stuck. Measuring right avoids this. It’s simple but critical.
Measure wall height, width, and floor space. Height needs 80-90 inches for vertical beds. Width depends on bed size. Add 10 inches for clearance. Depth needs 16-24 inches when folded. Use a tape measure. Check for obstacles like lights or vents. Our store offers free sizing guides.

I go deeper into measuring. Accuracy saves time and money.
Wall Height
Check ceiling height. Vertical beds need 80-90 inches. I measure twice. Low ceilings need horizontal beds.
Wall Width
Add 10 inches to bed width. A queen needs 70 inches. I mark walls to visualize. It helps.
Floor Space
Ensure room for the bed when open. A queen needs 80 inches out. I test this with tape.
Mechanism Clearance
Lifting systems need space. Cabinets add depth. I check this at Yechen. Pistons need more room than springs.
Here’s a measurement guide table.
| Measurement | Vertical Bed | Horizontal Bed | Why It Matters |
|-------------|--------------|----------------|---------------|
| Height | 80-90 inches | 45-60 inches | Fits wall |
| Width | Bed + 10 inches | Bed + 5 inches | Clearance |
| Depth | 16-24 inches | 16-24 inches | Cabinet fit |
| Floor | Bed length | Bed width | Open space |
| Measurement | Vertical Bed | Horizontal Bed | Why It Matters |
| Height | 80-90 inches | 45-60 inches | Fits wall |
| Width | Bed + 10 inches | Bed + 5 inches | Clearance |
| Depth | 16-24 inches | 16-24 inches | Cabinet fit |
| Floor | Bed length | Bed width | Open space |
I guide customers on this. One ignored clearance. The bed hit a shelf. We fixed it. Measure carefully. Your bed will fit.
What Size Mattress Fits a Murphy Bed?
I bought a wrong mattress once. It didn’t fit the frame. Sleep was bad. I learned fast. Mattress size matters.
Murphy beds take standard mattresses. Twin is 39x75 inches. Full is 54x75. Queen is 60x80. King is 76x80. Thickness should be 8-12 inches. Foam or spring works. Check frame limits. Our beds at Yechen fit most mattresses. We stock them in our U.S. warehouse.

I explore mattress fit. The mechanism affects this too.
Mattress Dimensions
Match bed size exactly. A queen bed needs a 60x80-inch mattress. I double-check labels.
Thickness Limits
Frames hold 8-12-inch mattresses. Thicker ones strain mechanisms. I test this at work. Thin ones sag.
Material Choice
Foam is light. Springs are firm. I like foam for comfort. Customers choose based on feel.
Mechanism Impact
Strong pistons handle heavy mattresses. Weak springs don’t. I saw a bed fail from a heavy mattress. We use pistons at Yechen.
Here’s a mattress fit table.
| Bed Size | Mattress Size | Thickness | Best Material |
| Twin | 39x75 inches | 8-12 inches | Foam |
| Full | 54x75 inches | 8-12 inches | Spring |
| Queen | 60x80 inches | 8-12 inches | Foam |
| King | 76x80 inches | 8-12 inches | Spring |
I advise customers on this. A friend picked a thick mattress. It broke the frame. Check specs first. You’ll sleep better.
Vertical vs Horizontal Murphy Bed Dimensions?
I chose a vertical bed once. My ceiling was low. It didn’t work. I switched to horizontal. It fit. Orientation matters.
Vertical beds stand tall, needing 80-90 inches of height. They save floor width. Horizontal beds need less height, about 45-60 inches, but more wall width. Both save space. Vertical is common. Horizontal fits odd rooms. Our store offers both, shipped from our U.S. warehouse.

I dig into orientation. Mechanisms change dimensions here too.
Vertical Bed Dimensions
Need 80-90 inches high. Width is bed size plus 10 inches. I install these most. They’re standard.
Horizontal Bed Dimensions
Need 45-60 inches high. Width is bed length plus 5 inches. I suggest these for low ceilings.
Room Suitability
Vertical fits tall, narrow rooms. Horizontal suits wide, low spaces. I measure to decide.
Mechanism Needs
Vertical uses stronger pistons[^1]. Horizontal needs less force. I check this at Yechen. It affects cabinet size[^2].
Here’s a comparison table.
| Type | Height Needed | Width Needed | Best Room Type |
| Vertical | 80-90 inches | Bed + 10 inches | Tall, narrow |
| Horizontal | 45-60 inches | Bed length + 5 inches | Low, wide |
I helped a client pick horizontal. Their low ceiling demanded it. Vertical failed them before. Check your room shape. Pick what fits.
Conclusion
Finding the right Murphy bed size transforms your home. I covered standard sizes, measuring tips, mattress fit, and vertical versus horizontal dimensions. My experience at Yechen Home Furniture shows beds must match room and mechanism. Our Shopify store and U.S. warehouse make it easy. Pick the right size. Measure carefully. Check mattresses and orientation. Your small space will feel bigger. Try a Murphy bed. It changes everything.
