Choosing the right bed size for your RV can make a big difference in how well you rest on the road. Many RV owners feel confused when they see terms like “Short King” and “Standard King.” They sound similar, but they are not the same.
In this guide, you’ll learn the exact size differences, how each option fits in an RV, and how to choose the best one for your setup. This will help you get better comfort without wasting space.
What Is a Short King RV Mattress
A Short King is one of the most common bed sizes used in RVs. It is designed to save space while still giving couples enough room to sleep.
Typical Short King size:
- 72 inches wide
- 80 inches long
This size is slightly narrower than a regular king bed, but it keeps the same length. That means most people can still stretch out comfortably.
Why RVs Use Short King Beds
RV makers use Short King beds because space is limited. Every inch matters inside an RV. By making the bed a little narrower, they create more room to:
- Walk around the bed
- Open cabinets and drawers
- Fit the bed inside slide-outs
Where You’ll Find Short King Beds
Short King beds are common in:
- Travel trailers
- Fifth wheels
- Mid-size motorhomes
They are a smart balance between comfort and space.

What Is a Standard King Mattress
A Standard King is the same size you would find in a house. It is the largest common bed size and offers the most sleeping space.
Standard King size:
- 76 inches wide
- 80 inches long
This makes it 4 inches wider than a Short King.
Why Some RVs Use Standard King Beds
Larger and more luxury RVs sometimes include Standard King beds. These RVs have more space, so they can fit a bigger bed without making the room feel cramped.
Benefits of a Standard King
- More space for couples
- Better for families with kids or pets
- Feels more like home
Short King vs. Standard King: Key Differences
1. Size Comparison
The biggest difference is width:
- Short King: 72 inches wide
- Standard King: 76 inches wide
Both are the same length at 80 inches.
That extra 4 inches may not sound like much, but it can make a big difference in a small RV.
2. Space Inside Your RV
In an RV, space is everything. A wider bed can:
- Reduce walking space
- Make it harder to change sheets
- Block storage areas
A Short King gives you more room to move around, which is very helpful in tight layouts.
3. Comfort and Sleeping Space
A Standard King gives each person more personal space. This can help if:
- You toss and turn at night
- You sleep with kids or pets
- You prefer extra room
A Short King still works well for most couples, especially if space is limited.
Pros and Cons of Each Option

Which RVs Use Each Bed Size

Always check your RV’s specs before buying a new bed. Even small differences can affect fit.

How to Measure Your RV Bed Platform
Before you buy anything, measure your bed space carefully.
Simple Steps:
- Measure the width from side to side
- Measure the length from head to foot
- Check for tight corners or curved walls
- Look at slide-out clearance if your bed moves
Common Mistakes:
- Guessing instead of measuring
- Forgetting about space to walk around
- Not checking height or thickness
Taking a few minutes to measure can save you a lot of trouble later.
Can You Replace a Short King with a Standard King
Sometimes you can switch sizes, but it depends on your RV layout.
It May Work If:
- You have extra space on both sides
- Your bed is in a large slide-out
- You don’t mind tighter walkways
It May Not Work If:
- Space is already tight
- Storage doors or closets are nearby
- You need room to move around easily
Always test the space before making a change.
Bedding and Fit Tips
Finding sheets for a Short King can be a little harder, but there are simple solutions:
- Look for “RV King” bedding online
- Use deep-pocket sheets for better fit
- Consider custom bedding if needed
Standard King bedding is much easier to find in stores, which is a big plus.
How to Choose the Right Size
Choosing the right bed depends on your needs.
Pick a Short King if:
- Your RV is smaller
- You want more walking space
- You value function over extra width
Pick a Standard King if:
- You have a larger RV
- You want maximum comfort
- You don’t mind using more space
Think about how you travel and what matters most—space or comfort.
Final Thoughts
The difference between a Short King and a Standard King may seem small, but it can have a big impact inside an RV. A Short King helps you save space and move around more easily. A Standard King gives you more room to stretch out and relax.
Before you decide, measure your space, think about your comfort needs, and consider how your RV is set up. The right choice will help you enjoy better rest on every trip.
