You are watching: Can you put a king mattress on a queen frame
Are you revamping your home and searching for a new bed for your guest or master bedroom? It’s important to remember that while this may seem like a simple decision, there is a lot you should know about the queen and king size mattresses and queen or full bed/frame that will help you make a more informed decision.
You can and should put a king mattress on a queen or full bed frame if you possess an adjustable bed frame that can be switched from queen to king size. Otherwise, a king-sized mattress cannot fit on a queen bed frame in terms of width and you will have to buy a new bed frame for it.
The rest of this article will discuss topics related to this question, like putting a king mattress on a queen bed frame, switching from a queen to king-sized bed frame, adaptations to consider when switching from queen to king-size bed, and some DIY thoughts.
Can You Put a King Mattress on a Queen Frame?
You need to know that you can’t put a king mattress on a queen frame. Unless you’ve got an adjustable bed frame (can be moved from queen to king size), it can prove impossible for your king size mattress to fit on your queen frame (width-wise). For some people, this doesn’t just mean getting a new bed frame, but also getting rid of and disposing of the pieces.
Should You Put a King Mattress on a Queen Frame?
You should not try putting a king mattress on a queen frame because the queen frame is smaller than the king mattress by sixteen inches. However, there is a way you can fit a queen size mattress on a king size bed frame.
Take note that a king bed frame can hold a mattress that’s 80 inches long and 76 inches wide. Queen size mattresses are 80 inches long and 60 inches wide. When fitting your mattress, the frame will hold your mattress, but part of the frame will be sticking out.
What Are Your Bed Frame Options?
Given that it can prove challenging to put a king mattress on a queen frame, the other alternative you may want to try is to fit a king-size headboard, for instance, the Ravenna Home Haraden Modern Curved Top to a steel bed frame like the Zinus Van 16inch Metal Platform.
Can You Fit a King Size Headboard on a Queen Size Steel Bed Frame and Mattress?
Suppose you find it difficult to put a king-size mattress like the PrimaSleep 9 Inch Multi-Layered Memory Foam on a queen frame. In that case, the next question you are probably asking yourself is whether it’s possible to purchase steel bed frame parts then use them in making a king size headboard adapt to your queen size mattress box spring and bed frame. If this is something you want to try out, you should know that it cannot work.
This is especially the case if you plan to have your headboard look acceptable and normal to others. It’s still essential to understand that a steel bed frame that best suits a king size mattress is seventy-six inches wide. This frame size is perfectly suited to hold a king size headboard. Take note that the king headboard may be a bit wider than the steel bed frame and mattress by about an inch. The headboard is structured this way for aesthetic purposes.
A king size headboard is slightly larger than a queen-size bed frame and mattress by sixteen inches. This means that when you are using the headboard with a mattress, it will leave 8 inches of the headboard exposed on either side, which looks unattractive.

Switching From Queen to King Size Bed
If you have finally decided to make a switch from a queen to king-size bed, there is a lot you should take into account when making such a switch. One of the notable benefits of the king-size bed than the queen counterpart is that you get an additional sixteen inches, which comes in handy when sleeping with your kids or pets.
The extra space is also perfect for anyone who enjoys moving around freely and comfortably. When planning to make a switch from a queen size to a king-size bed, you should know that there are a lot of things involved than just purchasing a new set of mattresses and determining whether it’s going to fit or not.
Adaptations to Consider
When planning to switch your mattress from a queen to king, you’ll have to invest in a metal bed frame, for instance, the Homdock 14 Inch Metal Platform Bed Frame. The only time this may not be a requirement is if you’ve got an adjustable bed frame, you can easily switch from queen to king. If you don’t have an adjustable bed frame, the other cost-effective way you can make an upgrade is by making the switch yourself.
In instances where you have to slide your headboard into a notch in your post, consider adding the depth of your notch to 76 inches (193.04 cm). Remember that this is the standard size of your king-size bed. You should then use a circular saw or table saw to cut your footboard and headboard to the right height and length.
Make sure that your height is similar to your previous footboard and headboard. In some cases, the groove you’re sliding to the headboard may not fit the board you’ve selected. If this is the case, you will have to trim the end of your board so that it can fit your groove. By using a pencil, ensure that you’ve marked off the diameter and depth of your groove. You should then cut the board size you need to use using a table saw or jigsaw.
The next important step is to sand your footboard and headboard edges so that they can perfectly slide into place. If you find it necessary, you may want to consider screwing them into place using a drill. You should still make sure that you’ve measured the distance of the inside of one of your sideboards to the other. Usually, this distance should be less than 76 inches, but this will depend on the depth of your sideboard.
Before using a drill, make sure that you know how it works and takes all the safety precautions.
Lastly, make sure that you’ve cut slats equal to this length, and then screw them into place using the bolts or screws from any previous slats.
If you take a DIY approach to convert your queen size to a king-size bed, you will be getting a bed upgrade and saving money at the same time. A king-size bed measures (76*80), while queen size measures (60*80). When making the upgrade in such a case, all you’ve got to do is change your footboard and headboard width.
If you’ve got a bed frame made out of wood, you should consider cutting a new footboard and headboard to expand your frame. The first step to take when converting your queen to king bed is to remove the footboard and headboard then detach any supports or slats that run horizontally on your bed frame.
The next step is to get the exact measurements where the footboard and headboard connect with your bedposts. Many wooden bed frames will have this point bolted in place or slide a notch in the bedpost. In instances where they slide a notch, it’s best to get the measurements of the notch’s depth, width, and height.
It is also important to remember that there is a substantial difference between the king and queen bed. One of the most notable differences is the sixteen-inch width left on both sides. If you didn’t have an idea of fitting your king size mattress on a queen-size bed, this guide should have provided you with the answers you need and any other options you may want to consider.
If you had already invested in queen-sized sheets, you’d probably have to consider picking out a new set for your king size bedspread.
