Looking to buy a new mattress/sheet or even a duvet, but don’t remember the size of your bed? Are you an international shopper using a different measuring system? Or maybe you are a student who is away from home and trying to figure out bedding by yourself.

Whether you are shopping for the first time for bedding items or have simply forgotten the size of your bed. Look no further, we have compiled a complete guide to all your bedding needs in one place.

We understand it’s easy to be overwhelmed by the variety of sizes and options available for bedding items and get confused about how to match bedding sizes and bedsheet sizes with the many mattresses and bed dimensions there are.

Here you will find a detailed guide to the sizing options (dimensions) available, how to measure your bedding size, why is it important, and also how to match it with your bedroom style. 

The basis for understanding your bedding sizes should start with looking at the size of your mattress. The sizes below are the ones we use at Down Under Bedding and mattress, but should not be the basis for your mattress size. It is always best to measure your bed/ mattress before making a bedding purchase. 

Mattress Sizes

We hear you- It is even more confusing if you are from another country and have different sizes for your bedding. So, let’s understand the different bedding sizes available at Down Under Bedding and Mattress

Single/Twin

A twin or sometimes also referred to as single bedding size, has ideal dimensions of 39″ x 75″ (inches) – 99 cm x 190.5 cm (centimeters). This size of mattress is perfect for kids, or single sleepers, even though most adults find this size small. Twin beds work best for a small kid’s room/ small guest room/ den, and even for odd-shaped spaces.

Twin Extra Long

This twin extra long is a popular selling item for growing kids and solo sleepers as it is longer than the single-sized option, the size available for this is 39" x 80" (inches) — 99 cm x 203 cm(centimeters). Even though this size does not offer extra width than the single/ twin, it does have extra leg space for tall sleepers. This makes it perfect for dorm rooms and for growing kids' bedrooms.  

Double/Full

This mattress with size 54″ x 75″ (inches) – 137 cm x 190.5 cm (centimeters), offers a good conciliation between extra long twin and the queen size. This size turns out to be a good feasible option for single sleepers as it offers a good length and width space. Best choice for small apartments, guest bedrooms, and dorm rooms.  

Queen

The queen-size bedding mattress is the most popular bed size among couples. With dimensions 60″ x 80″ (inches) – 152.5 cm x 203 cm (centimeters), this mattress offers ample space for two adults to sleep comfortably throughout the night.

Did I mention……they are the most adaptable sizes out there? Whether you are a single sleeper or have to share your bed, this size is perfect for everyone. They are the most popular sizes out there which also means that you can find super cool accessories such as duvet covers, fitted bedsheets, and comforters in this size….which too is within your price range.

King

This one is my favorite……as you may have guessed by the name “King”! This size offers the most luxurious amount of space. With dimensions, 76″ x 80″ (inches) – 193 cm x 203 cm (centimeters) this size is large enough to share your beds with kids or pets. Even though it may be bulky and heavy to move around, it is worth it when you get to sleep on it like a king! 

The most simple and effective way to measure your bed size is by using a measuring tape to determine the height, length, and width of your bedding (for when you are buying a mattress). While shopping for a bedsheet, duvet, comforter, or coverlet; you may want to look at the height, length, width, and thickness of your mattress. Keep reading to get a better understanding!

Take a look at some ways you can make sure you purchase the right-sized duvet for your bed. Here at Down Under Bedding and Mattress, we understand it’s easy to get confused with the variety of bedding options available, and that is why we have created the perfect guide for you. Take a look at this chart to get a better understanding: 

 

What Is The Most Popular Mattress Size?

Perhaps the most popular size is the elegant queen-size bed/ mattress. This is because of many reasons:

Firstly, they are considered the standard size in almost all places be it hotel rooms, apartments, or even in your home bedroom. They are perfect for single sleepers, those sleeping with a partner, or even those sharing it with your small kid. Since this is the most ideal size of bedding available out there, means there's more variety. You can find this in every type, price range, color, and design. Before I forget……it is easy to transport and shift rather than your king-size mattress. It also strikes a middle ground in terms of economical options. But don’t take our word for it……it is best that you do your research to decide the best option for you.

Buying the right-sized duvet/ comforter can be challenging, because different manufacturers might offer different specifications when it comes to bedding items. Even though standard sizes might offer a starting point for selecting a duvet for your bedding, you should always check the measurements to be precise. Choosing the right-sized duvet to top your mattress can be a challenge when manufacturers often confuse the sizing standards. Or you might find that the mattress sizes differ from one country to another. So, sizes are also particular to the company’s sizing standards. The best way is to always measure before buying.

Keep in mind that you should always keep a measuring tape handy when buying bed-topping accessories.

Match Your Duvet To Your Mattress

Mattresses of the same name could vary in size, even by a few inches; depending on the country. Moreover, keep in mind that within each category, comforters can come in a range of lengths and widths, so pay attention to the thickness of your mattress. If your mattress is on the thick side, you should look for a duvet/ comforter in the top range of dimension sizes, or maybe even consider getting a bigger size. For example, if you have a queen-size bed and consider getting a king-size duvet- it could work and might also be a good idea as it would give you enough space for tucking your duvet in your bed for a neat look.

Could also save you the hassle of fighting for a warm blanket through the night! 😉

On the other hand, a larger king-sized duvet could potentially fall closer to the floor as it would not be a good fit for a queen-sized bed.  

Choosing the right-sized comforter can be a challenge, especially when manufacturers tend to label them as a good fit for a full-sized queen bed. This is why it is always best to check for measurements!

 

Should I Get An Oversized Duvet??

It is fine for your duvet to be slightly oversized, especially if it is on the puffier side; but keep in mind that since these comforters offer more length and width space, it may tend to reach the floor and not look very appealing. You may risk going a size bigger if you prefer oversized comforters, but it is also best to take exact measurements to be precise. 

What Is The Difference When Describing Bed Versus Mattress Size? Does it really matter?

Bed size and mattress size are simply terms that are used interchangeably to describe the size of either your bed or your mattress. When people refer to a king-size bed, it would mean that you would need a king-size mattress with it.Be sure to always check the exact dimensions regardless of the name or the size.Since sizing standards vary from manufacturer to manufacturer, you must compare and take note of the size you are looking for while making a bedding item/ accessories purchase. 

What's the time??

It's time for a sheet joke

What did the blanket say when it fell off the bed?

Oh, sheet!

Hahaha, let's dig right into sheets!!

Umm….that’s not what I meant, Clara. I meant let’s get to understanding sheet size…. 

Understanding Sheet Sizes 101

When it comes to shopping for bedsheets, you need to be careful. You may have some room for error when it comes to the size of duvet covers, comforters, and also flat sheets, but not when it comes to fitted sheets. When it comes to fitted sheets, you need to be more accurate. Otherwise, it would be too loose and keep drifting off or too tight to even stay in place! Take note that each size comes with a set of specific length and width measurements, so you should take a close look at the thickness of your mattress. Fitted sheets are meant to exactly fit your mattress, which means you better be exact, or you might be up all night trying to adjust the length of your sheet. With a large sheet, you might still have some room for adjustment by tucking it under the mattress, but with a small fitted sheet, you won’t even be able to fit it over the mattress.

Depth of Your Mattress

Before shopping for bedsheets, make sure you know the depth of your mattress. The thickness of your mattress is the size of your mattress from top to bottom. It is essential to know the depth/ thickness when purchasing new sheets as it may alter the fit size of standard sheets. 

Fitted Sheet Or Flat Sheet!

When buying a fitted sheet, you have to be very precise with the measurements, they need to be very close to your mattress to ensure a proper fit. The best way to measure the size of a fitted sheet is it look at the thickness of your mattress. The pocket depth of your sheet may vary from 25 cm to 45 cm, which is around 10”- 18” (inches).

As for a flat or stand-alone sheet, you don’t have to worry too much about the thickness of your mattress. 

A bit of simple advice for flat sheets: the bigger the size the better it stays tucked in! 

It is important to understand the length and width adjustments when it comes to buying a flat sheet. Keep in mind to align the long side of your sheet to the long side of the bed, many people don’t place their sheets in the correct way and realize that they keep coming off.

A noticeable difference between those two is that a fitted sheet comes with four corners whereas a flat sheet is simply a piece of fabric with length and width measurements.  

What To Look For When Buying A Fitted Sheet?

There are three main things you should keep in mind when shopping for fitted sheets- thread count, pocket depth (measure the thickness of your mattress), and strength. You can read all about the importance of thread count here, but just to sum it up, it helps measure the durability of your sheet. Pocket depth refers to the depth/ thickness of your mattress and helps determine if your sheet will be tucked in properly or not. This is an essential factor when buying a fitted sheet. The strength of your sheet can be checked by looking at the quality of fiber used to make your sheet.
