When you begin researching for your next mattress purchase, it might get confusing as to which size should be perfect. Picking the right mattress size is essential as it will help you determine your sleep posture and overall sleep health

An uncomfortable mattress might lead you to a night of tossing and turning, leaving you drained out by morning. A mattress of the wrong size can also lead to back pain. As a buyer, you should know the size you require as it varies for different individuals. While some may buy it for adults or couples, others may buy it for kids; the size requirement for all these instances will differ. 

As many customers do not know what is the right mattress size, our mattress specialists often come across the following questions from customers- 

  • I have a small bedroom, will a king-size bed fit into it?
  • Is it a must to buy a king-size bed if I have a family?
  • What would be the ideal bed size for my kids? 

A person spends almost a third of their day on a mattress, so the need for it to be of a perfect size is even greater. Before knowing what bed size is right, you must read through these critical factors that determine your choice. 

4 points to consider while choosing the right mattress size 

#1 The size of the sleeper

It is essential for someone tall to pick a mattress that offers some extra inches of length for legroom. If you are more than 6 feet 2 inches, a Twin size or even Full-size mattress can feel small for you. For those with a wider build, it is suggested that you get a Full-size or a Queen-size mattress for comfortable sleep.

#2 The total number of people sleeping on the mattress

If you plan to share the mattress with a partner, kid, or pet, it is suggested you should at least consider buying a queen-size mattress. On the other hand, if you plan to share the mattress with more than two people, then a King size or a Cal King-size mattress would be a perfect choice. A Full-size or Twin-size mattress might feel perfect for a solo sleeper. However, that depends on how much space you would want to have on the mattress. 

#3 The size of your room

If you have a studio apartment or a small room, getting a large mattress will eliminate the space for other essential furniture. It will also make the room look congested with less walking space. Hence, always keep your room size in mind before choosing the mattress size. 

Here's a tabular guide for you to know better about what is the right mattress size for your room according to its size- 

Room name Average room size  Best fitting mattress size
Kids room  11 feet x 12 feet  Twin mattress 
Guest room  9 feet x 12 feet  Twin XL
Master bedroom  11 feet x 15 feet King Size/ Cal King 
Studio apartment  16 feet x 24 feet  Twin/Twin XL

*These are average estimates, the real dimensions might vary according to the specific property you live in.

#4 The budget

The larger the mattress, higher the price. This is why it is essential to understand your requirements and then invest in a mattress that fits your room, comfort, and budget.

To further ease your stress of picking the right mattress size. We have created a mattress size guide.

California King Size

Size- 72 inches by 84 inches

King size

Queen size
