Your Ultimate Guide To Choosing The Right Mattress Size

Your Ultimate Guide To Choosing The Right Mattress Size

Are you tired of tossing and turning on a mattress that's too small or too big for your needs? As mattresses come in many different sizes, ranging from a single to a king, it is important to choose a size that best fits you and your space. The right mattress size provides enough space for you to move around comfortably during your sleep. A poorly sized mattress will impact the quality of your and your partner’s sleep, and keep you up at night.


Understanding Mattress Sizes

Before we go into the specifics of choosing the mattress size, let's familiarize ourselves with the standard mattress dimensions in Singapore:

  1. Single: 91 cm wide by 190 cm long
  2. Super Single: 107 cm wide by 190 cm long
  3. Double: 140 cm wide by 200 cm long
  4. Queen: 152 cm wide by 190 cm long
  5. King: 180 cm wide by 190 cm long


The following are some key considerations when choosing the size of your new mattress. 

Size Matters

The wider your build, the wider the mattress you will need. Since many of us will toss and roll around during sleep, you will need to cater for space to move around on the mattress. When considering the length of your mattress, factor in at least an additional 20 cm over the height of the tallest person sleeping on the mattress.


Factor in Co-sleeping Arrangements

One of the most important factors to consider is the number of people sleeping on the mattress. There should be sufficient space for everyone to move around during sleep. If you are sleeping by yourself, a single, Singapore super single, or European double should suit you well. If you plan to share your bed with a partner, a child, or a pet, then the smallest mattress size to consider will be a queen.

Your budget will determine the available options for consideration. In general, the bigger the mattress, the more it is going to cost you. Always set yourself a realistic budget and work within it.


Assess Your Bedroom Space

The bed likely isn’t the only piece of furniture in your bedroom. It is important to choose a mattress that will fit the size of your bedroom. Take into account other furniture pieces, such as nightstands, dressers, and bed frames, to ensure adequate clearance and maneuverability. Leave at least 50 cm of walking space around your bed so you can move around the bedroom without obstruction. Also, note that a busy, overcrowded bedroom can cause stress and disturb your sleep.

Think about Future Needs

When choosing a mattress size, consider your future needs and lifestyle changes. Are you planning to upgrade to a larger bed in the future, or do you anticipate sharing your bed with a partner? Investing in a mattress size that accommodates potential changes can save you from having to replace your mattress prematurely.


Test out Different Sizes

If possible, visit a mattress showroom or store to test out different mattress sizes and see how they feel. Lie down on each mattress to gauge comfort and assess whether it provides enough space for you to move around freely. Pay attention to how the mattress supports your body and alleviates pressure points in various sleeping positions.


Choosing the right mattress size is a crucial step in achieving a comfortable and restful sleep experience. By considering factors such as your sleeping preferences, bedroom space, future needs, body size, and co-sleeping arrangements, you can select a mattress size that meets your requirements and enhances your sleep quality. Whether you're in Singapore or elsewhere, investing in the right mattress size is an investment in your health and well-being for years to come.
