Discover the custom mattress size that gives you more sleeping room without taking over your bedroom.
A Queen mattress can feel crowded for two sleepers—but a King mattress may simply be too large for the room.
This is especially common in city apartments, older homes, condominiums, guest rooms, and bedrooms with limited walking space. A standard Queen measures 60″ wide by 80″ long, while a standard King jumps all the way to 76″ wide by 80″ long. That 16-inch difference leaves plenty of room for a better-fitting option in between.
For many customers, a custom mattress measuring 66″ or 68″ wide by 80″ long provides the ideal balance: noticeably more room than a Queen without the space demands of a King.
Find the Size That Fits Your Room
Get the extra sleeping space you want with a custom 66″ or 68″ mattress—and add a matching platform bed for a complete, properly supported setup.
Mattress Sizes Between Queen and King
| Mattress size | Dimensions | Difference from Queen | Space saved vs. King |
|---|---|---|---|
| Standard Queen | 60″ × 80″ | — | 16″ narrower |
| Custom 66″ | 66″ × 80″ | 6″ wider | 10″ narrower |
| Custom 68″ | 68″ × 80″ | 8″ wider | 8″ narrower |
| Standard King | 76″ × 80″ | 16″ wider | — |
A 66″ mattress gives each person approximately three additional inches of personal sleeping width compared with a Queen. A 68″ mattress provides approximately four additional inches per person.
That may sound modest, but it can make a meaningful difference—particularly if one sleeper changes positions frequently, if you occasionally share the bed with a child or pet, or if a standard Queen simply feels a little too close for comfort.
Why Not Just Buy a King?
A King mattress offers plenty of sleeping space, but the mattress is only part of the equation. You also need room for the bed frame, nightstands, doors, drawers, and comfortable walkways around the bed.
In a smaller bedroom, the extra width of a King can:
- Make walkways feel narrow or cramped
- Leave too little space for nightstands
- Interfere with closet doors or dresser drawers
- Make the room appear crowded
- Create a difficult fit in apartments with tight hallways, stairways, or elevators
Choosing a 66″ or 68″ mattress allows you to add valuable sleeping space while preserving more of the room around your bed.
A Smart Choice for Smaller City Bedrooms
Every inch matters in a city apartment. A room that technically accommodates a King mattress may not function well once the rest of the furniture is added.
By choosing a mattress eight or ten inches narrower than a King, you can maintain a more comfortable walkway or keep space for a nightstand, dresser, chair, or storage solution. At the same time, the bed feels more spacious than a standard Queen.
This makes an in-between mattress especially useful for:
- Apartments and condominiums
- Older homes with smaller bedrooms
- Couples who find a Queen too crowded
- Rooms with unusual layouts
- Bedrooms where doors or furniture limit the available width
- Anyone who wants more sleeping room without letting the bed dominate the space
Should You Choose 66″ or 68″ Wide?
Both sizes provide more room than a Queen. The best choice depends on your bedroom and how much clearance you want around the bed.
Choose 66″ × 80″ if:
- Your available space is especially tight
- You want more room than a Queen while keeping the bed compact
- Preserving comfortable walkways is a priority
- A 68″ mattress would interfere with furniture or doors
Choose 68″ × 80″ if:
- You want the most sleeping width your room can comfortably accommodate
- You share the bed with a partner, child, or pet
- You have enough room for two additional inches of mattress width
- You want a size that feels closer to a King while remaining easier to fit
When possible, mark the proposed mattress dimensions on the floor with painter’s tape. This gives you a simple way to see how the bed will interact with your furniture and walkways before ordering.
How Much Space Should You Leave Around the Bed?
There is no single measurement that works for every bedroom, but you should be able to move around the bed and use nearby furniture comfortably.
Before choosing your mattress width, check:
- The exact available width and length of the sleeping area
- The outside dimensions of your bed frame—not just the mattress
- Clearance for bedroom and closet doors
- Space needed to open dresser drawers
- Room for nightstands and electrical outlets
- The delivery path through doors, hallways, stairs, or elevators
Remember that the outside dimensions of some bed frames may be several inches larger than the mattress itself.
Complete the Fit with a Matching Custom Platform Bed
Finding a 66″ or 68″ mattress is only half of the solution. Bed frames in these widths are also very difficult to find.
Custom Mattress Makers can provide both your custom mattress and a matching Custom Size Platform Bed Frame. The platform provides complete mattress support, so no separate foundation or box spring is required. For widths over 60″, the platform is supplied as two matching bases that sit side by side beneath one mattress.
Choose the same width and length for both products, and you will have a coordinated sleep setup made specifically for your room.
What About Custom Sheets and Protection?
Because 66″ and 68″ mattresses are nonstandard sizes, standard Queen fitted sheets are unlikely to fit properly. Custom Mattress Makers offers custom-size sheets, mattress protectors, and mattress pads for a secure fit.

Frequently Asked Questions
Is there a mattress size between Queen and King?
Although there is no widely recognized standard U.S. size between Queen and King, a custom mattress can be made in an intermediate width. Popular choices include 66″ × 80″ and 68″ × 80″.
How much wider is a 66-inch mattress than a Queen?
A 66″ mattress is six inches wider than a standard 60″ Queen. When two people share the bed, that provides approximately three additional inches of sleeping width per person.
How much wider is a 68-inch mattress than a Queen?
A 68″ mattress is eight inches wider than a Queen, providing approximately four additional inches per person when shared by two sleepers.
Is a 66-inch mattress smaller than a King?
Yes. A standard King is 76″ wide, so a 66″ mattress is ten inches narrower. Both are normally 80″ long.
Is a 68-inch mattress smaller than a King?
Yes. A 68″ mattress is eight inches narrower than a standard King while providing the same 80″ length.
Can I use standard Queen sheets on an in-between mattress?
A standard Queen fitted sheet is unlikely to fit properly because it is designed for a 60″-wide mattress. Custom-size fitted sheets and mattress protectors will provide a more secure fit. Depending on your preferences, a standard King flat sheet or top bedding may still work.
Do I need a custom bed frame or foundation?
Your mattress must have adequate, correctly sized support. The Custom Size Platform Bed Frame can be ordered in the same width and length as your mattress and does not require a separate box spring or foundation.
How do I order a 66″ or 68″ mattress and platform?
Visit a mattress product page and select 66″ or 68″ for the width and 80″ for the length. Then visit the Custom Size Platform Bed Frame page and select the same dimensions for the matching support.
