Choosing The Right Mattress Size: A Definitive Guide

It is a common belief that a good night's sleep can turn a bad day around, and as one would expect, coming home to something capable of clearing your mind off a tiring day is Godsent.

Additionally, resting is essential for our brain and body to go about their day-to-day functions properly. Without it, the tiring-day cycle would only repeat itself. That's how important sleep is.

Likewise, there are a few things that hold just as much importance as sleep. These are the factors that help us enjoy a sound slumber. One of these is a mattress.

You can imagine just how invaluable a mattress must be if it is deemed essential in determining a good night's rest.

Previously, we had posted a comprehensive guide on the various factors to consider while going mattress shopping.

Following that, this article will be a handbook to choose the right mattress size for you.

Before we get into more details, a few sub-factors are involved in the decision-making process. These include:

  • The size of the room
  • The size of the bed
  • The number of people you will be sharing it with

For the first two, use a measuring tape to note down the accurate dimensions. As for the third, discuss the number of occupants by considering the availability of rooms and comfort level.

Once you have enough information, start weighing your options and choose the one you deem fittest.

The choices might seem overwhelming and leave you confused. That's why we have provided tips on whom each mattress size would suit the best.


At best, a single-size mattress can fit one person comfortably and is suitable for smaller rooms. It could either be one adult or one child sleeping on it. Anything more than this will feel too cramped for everyone occupying space on the bed.

This mattress is a popular choice among kids, teenagers, and those who live alone.

  • 75x36 inches (6.25x3 feet)
  • 78x36 inches (6.5x3 feet)





Also known as Diwan, this mattress can perfectly fit two children or an adult and a child. Although two adults can sleep on this, the room for comfort is doubtful.

However, since it is wider than the single-size mattress, two grown-ups can occupy the bed, provided they are relatively shorter in height.

Queen-size mattresses are the most popular kind, owing to their compatibility with most bed frames. They are also the go-to choose for couples.





These mattresses are befitting for vast spaces and favorable towards nuclear families with infants or toddlers. The size is wide enough to feel like a fusion of two single-size beds, making it the most suitable choice for heavy sleepers who tend to roll over or move around.
