Mattress Sizes 

There is no one-size-fits-all solution when it comes to purchasing a new mattress, so it's critical to consider your specific requirements, like the size of your bed, which will determine the size of the mattress. Here's a breakdown of mattress sizes

Single Mattress Size

As its name implies, a single mattress is best for single sleepers, children, or if you're situated in a very small apartment where space is critical. These mattresses typically measure 920mm x 1880mm, and you'll want to put them in a room that measures at least 2.1m x 2.7m. 

Long Single Bed Mattress Size

Long single mattresses measure 920mm x 2030mm, and are suitable for fast-growing teens, tall adults, or children going to boarding school, as their size allows for extra length. They fit best in 2.5m x 3m large rooms. 

King Single Mattress Size

Measuring 1070mm x 2030mm, the king single-size mattress is the most comfortable sleeping mattress for single individuals who want to maximise their sleeping space. They typically fit in rooms that measure at least 2.8m x 3.2m.

Double Bed Mattress Size

Double bed mattress size is a good choice for young adults or recent graduates living on their own for the first time. These mattresses measure 1370mm x 1880 mm. They are perfect mattresses for guest rooms, single individuals looking for maximum comfort, or couples living in smaller apartments. These mattresses are ideally set in rooms that are at least 3m x 3.5m large.


Queen Size Mattress

The queen-size mattress is the most popular mattress size on the market, typically used for the master bedroom. The queen provides enough space for couples or single people who enjoy having more room to move around in bed, measuring 1530mm x 2030mm.

Due to its popularity, a queen-size mattress has the additional benefit of having vast style choices regarding bedding sets, bedroom furniture, and bed accessories. It's also probably the most cost-effective mattress size for couples. 

King Mattress Size

A 1830mm x 2030mm king-size bed is the epitome of luxury, as there's enough room for two people to spread out and still have their own private sleeping area on a single king-size mattress. King-sized mattresses are the widest standardised size available on the market, making them a suitable choice for couples and families. If parents wish to share a bed with their kids, this size can work.

Super King Size Mattress Size

Talk about maximising your available sleeping area! It's likely that you won't want to leave the super-king bed if you're considering a super king-size mattress. These mattresses measure 2030mm x 2030mm, making them great if your children enjoy hopping in for lazy weekend mornings, your pets enjoy sharing your space, or you simply enjoy performing kart-wheels in bed. 

To accommodate bedside tables and other furniture, king-size bed frames require a room to be at least 3.5m x 3.5m.

Mattress Buyer's Guide

Buying a new mattress is a pretty straightforward task; just go to the retailer and buy a new mattress. But buying a perfect mattress is a different story altogether. Here's what you have to know:

The Size of the Bedroom Matters

Remember that your bedroom includes more than just your bed. You must provide room for movement and other necessary furnishings. Your bedroom is your Fortress of Solitude, where you retire at the end of the day to rest and recharge. An overcrowded or stuffed bedroom increases stress which would make sleep more difficult.

The Size of You (And Your Partner)

When selecting the right mattress, you should consider your height and width. Always leave a 13 cm difference between your height and the mattress length for added comfort. This may be obvious to you if you are a particularly tall person, but a single or double bed is not going to be the ideal choice for tall individuals; you should at least consider a long single.

Consider the width in addition to the length. Make sure you all have enough room if there are two or more of you sharing this area.

Your Budget

Choosing the appropriate size might also be influenced by your budget for a mattress. Cost differences between a king and a queen, a double and a queen, etc., can sometimes be substantial. The goal is to purchase a mattress that satisfies both your size needs and your financial budget.
