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.

Switching From Queen to King Size Bed

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.

DIY Approach

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.

Final Thoughts

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.
