The Right Size Bed for My Height

Humans spend around a third of their life asleep. We also spend a lot of time in bed, browsing the internet, or watching TV. Being comfortable on your bed is vital for your health and happiness; this article looks at your mattress’s size according to height.

It doesn’t matter if you choose a bed and mattress with a high comfort level. Your sleep quality will be affected if your bed is not sized according to height. As for the length of your mattress, ideally, it should be 6 inches longer than your height to provide comfortable sleep.

Just as creating a good bedtime routine is important for a good night’s sleep, getting the right-sized bed and mattress according to your height is equally important. Let’s find out how that is measured.

How to Calculate the Right Size of Bed for Your Height.

To calculate the right size bed according to your height, you can measure your height and add 6 inches. Then choose a bed and mattress that is longer than that. Before selecting a bed size, you should also consider how wide the mattress is and that it provides comfortable elbow space.

There are many different sizes of beds and mattresses available, and it is easy to calculate the right size for you. Choosing the right size bed can be frustrating if you don’t know what sizes are available on the market and how to calculate the right size according to your height.

Where to Buy a Bed or Mattress

When buying the perfect bed or mattress, you must calculate the correct length according to your height and consider whether it will fit in your home, room, doorways, and staircase.

There are so many online stores available that feature great options. It is a convenient way of shopping without leaving your home. 

Scrolling through hundreds of pages to find the right bed or mattress can be a bit overwhelming. However, you don’t have to deal with following salespeople whispering in your ears the whole time.

What makes online shopping popular is that they offer many discounts, you don’t have to leave your home, free or discounted shipping, money-back guarantees, and will deliver your bed right to your door. The only problem is that you won’t feel the mattress before delivery.

In-Store Shopping

To have the chance to choose the mattress and feel how it holds your body, buying from a store is the best choice.

You can inspect the mattress before buying it when shopping from a store. The problem with this is that any testing options might confuse you.

Before choosing from a store, the best advice is to take enough time to feel what the mattress feels under your body. Don’t feel rushed by salesmen or women urging you to choose.

Take time to make the right choice and always shop for sales to get the best-priced bed.

What size bed should I get? It is a question we all ask at some point in life. The perfect-sized bed considers your height and bedroom size if you are married or single. Before choosing a bed, you must make some of these considerations.

Most people can effectively sleep on any mattress 6 inches longer than their height. 

Some mattresses vary in width, which should also be considered before you purchase a bed and mattress. If you have a partner, the larger-sized queen, king, or California king will provide ample bed and elbow space to sleep comfortably through the night without bumping into each other.
