Feeling Lost In The Vast World Of Countless Mattresses With A Variety of Sizes?

Your journey to buy a new mattress can become a lot easier if you know the right mattress size. However, it is common for people to select the wrong mattress size for their new bed and regret it later. Choosing the right mattress size can improve sleeping patterns as it promises a comfortable sleeping experience. After all, a mattress is a heavy purchase that you do not want to replace every other year. Right? Some people select bed mattress sizes that are way too small to accommodate both sleeping partners or their kids, while others end up buying a mattress that is too big to fit in their rooms. Large mattresses offer you ample personal space, but you do not want to pick a bed that makes your room look cluttered either. So, the question is whether you should opt for a small or a big mattress? What is the ideal way to select the right mattress size? What are the standard sizes available in India to choose from? How do you measure your bed perfectly to pick the right mattress size? Are there any additional factors that you need to consider while selecting your ideal mattress size?

If you have such questions popping up on your mind, we have got you covered! By sharing detailed information about different mattress sizes, we have curated this ultimate mattress size guide so that you can easily find your perfect mattress match for your bed without any hassles.

Moreover, it usually comprises two individual mattresses divided in equal half instead of one large block of a mattress, making it easier to move around whenever required.

How To Choose The Right Mattress Size?

Since selecting the right mattress size is more complicated than you may have thought, here are a few most important things to determine before purchasing it for your home. However, you must note that most of these factors are dependent on each other. Hence, it would be best if you made the final decision based on your priorities.

  1. Your Height

The size of the sleeper sleeping on the mattress plays the biggest role in purchasing a new mattress and bed frame. If you have an average height and have basic requirements, you can select between a single or double sized mattress depending on whether you intend to share the bed with someone.

Suppose you are tall and enjoy plenty of personal space and legroom. In that case, you should consider a wider and longer mattress to offer you uninterrupted comfort throughout the night. Taller people should generally opt for a queen-sized mattress, whereas those taller and plus-sized should consider buying a king-sized bed for themselves.

However, several other factors should influence your decision depending upon the availability of space in your room, your personal preferences, and your budget.

  1. Number of Sleepers

Whether you are a single sleeper or would be sharing the bed with a sibling, partner, child or pet also plays a significant role in selecting the right mattress size. For instance, an adult sleeping alone might buy a single sized mattress for themselves, whereas another adult who prefers more personal space while sleeping should opt for a twin or double sized mattress. The same goes for ones who share a bed with their partner or kids while also considering the room's size and height.

  1. Body Weight & Size

Just the way your height plays a crucial role in determining the length and width of the mattress, your body shape, size and weight also does. It means if your weight lies in the normal range as per your body mass index, you can generally opt for a 6 inches thick mattress. However, if you are on the plus-size or are highly overweight, your mattress should be at least 8 inches thick to offer optimum back support.

  1. Versatility & Personal Preferences

If you are sharing the bed with your partner, there might be two scenarios wherein you may both want to purchase the same mattress while you both might also have specific requirements for your bed. If you prefer a queen or king-sized mattress but want to have different firmness levels or primary materials, you should consider custom split sizes instead. Similarly, if you like tossing and turning a lot while sleeping, a larger bed might feel more comfortable to you as compared to a smaller one.

  1. Preferred Sleep Position

Some people are back sleepers, while others are side or stomach sleepers. And many of them are combination sleepers. Your preferred sleeping position also plays an integral role in the type of mattress you choose to provide moderate contouring to your curves. The same concept as shared in the fourth point would be relevant here. For example, if you are a back sleeper but your partner is a stomach sleeper, you both would have different requirements for your mattresses. In such cases, it is better to look for customized mattress sizes so that both of you sleep comfortably without compromising with your preferences.

Other Mattress Size Factors That Influence Your Decision

As you already know that choosing the size of your mattress involves a lot of factors into consideration, there are many other factors that you might neglect, but they play a huge role too. Here are some other factors you need to consider before settling on the size of your bed:

  1. Size Of Your Room

Who doesn't want maximum personal space while sleeping? But that doesn't mean everyone can buy a king-sized mattress. Hence, the size of your room and availability of space depending upon the other furniture you have positioned play a significant role in selecting the right mattress size for you.

After determining whether you want to share the bed with someone or not, the size of your room is the second most important thing while selecting a new mattress size.

  1. Your Preferred Sleeping Space

If you have a large master bedroom but do not require a lot of sleeping space or don't frequently change your position while sleeping at night, you don't necessarily need a queen or king-sized bed. Hence, it is essential to consider your preferred sleeping space while choosing your ideal mattress size.

  1. Future Moving Plans

If you rent an apartment, wish to move out to another home soon, prefer rearranging your room frequently or switch turns in acquiring the rooms in case of shared housing, you will need to move your mattress from time to time. Hence, buying an extra large and bulky mattress might be problematic at that time. A smaller or split mattress might be relatively easier and more comfortable to move in such a case.

  1. Location Of The Room

Even if you don't intend to shift out to a new home, the location of your room is equally important. After all, it can be troublesome to physically transport a huge mattress into a room with small doors or the ones located on the second floor. Similarly, if your room is only accessible by a narrow staircase, taking the mattress upstairs can be pretty tricky.

In such cases, you can either consider purchasing smaller mattress sizes or customized split mattresses. Conversely, you can also opt for a compressed mattress that comes in a box and expands to its full size within 24 hours on unpacking.

  1. Room Design & Symmetry

The bed in your room should be according to your requirements and availability of space. However, it must also comply with the geometry of your room. You must consider all the other things in the room, including the table, wardrobes, rugs, etc., to ensure the bed doesn't look too large or small compared to everything else.

  1. Your Budget

Lastly yet most importantly, it is crucial to determine your budget and buy the best mattress available to you. Although the mattress construction and primary materials used play a huge role in the pricing, generally, the bigger the size, the more expensive the mattress is.

You should research the best way to find a good quality mattress that fits your budget constraints and your size requirements. One of the easiest ways to manage this limitation is to buy the mattress via a no-cost EMI facility, but you should never settle for a cheap mattress to find your size requirements or save some money. Or else, you can be exposed to an array of allergies and/or body pain issues.

What Is the Ideal Mattress Height For You?

As mentioned above, your body weight plays a huge role in the support offered by your mattress. Regardless of what size you choose, the height of your mattress is dependent on your comfort. Usually, thicker mattresses are sought to be more supportive and hence, comfortable. However, the thicker the mattress is, the higher is the cost because of the extra material involved in the manufacturing process. Therefore, you can consider the height of the mattress as per your weight, personal preferences, and budget.

The bed frame should have the exact dimensions as the mattress. However, if you cannot find the same size, the bed frame can be 2 to 5 inches bigger than the mattress.

  1. Can the bed frame be smaller than the mattress?

No. The bed frame shouldn't measure smaller than your mattress and must have the same width and length as the mattress size. Buying a smaller bed frame than your mattress causes your mattress to start losing its firmness and break at the edges after a few months. Moreover, this could also lead to potential injuries in case you slip off.

  1. What can you do when your mattress is smaller than your bed?

Although you must carefully choose the right mattress size that fits your bed frame, there are some possible ways to fill the gap if your mattress is smaller than the frame. You can place pillows or blocks of foam to fill the gap strategically. If the gap is too large, you can get the bed frame fixed by a carpenter or professional to fill in the gap seamlessly.
