What Size Sheet Do I Need? The Complete Bedsheet Size Guide
Choosing the right bedsheet size sounds simple—until you find yourself with a sheet that keeps slipping off the mattress, leaves the corners exposed, or has far too much fabric hanging over the sides.
Whether you are shopping for a king size bedsheet, queen size bedsheet, double bedsheet, or single bedsheet, getting the measurements right makes all the difference.
In this guide, we’ll help you understand what size sheet you need, how to measure your mattress, and how to choose the perfect bedsheet for a comfortable and polished-looking bed.
Bedsheet Size Chart
Before buying a new bedsheet, check your mattress dimensions first. Bed sizes can vary between manufacturers, so measuring your mattress is always the safest option.
| Bed Size | Common Mattress Size | Recommended Bedsheet Size |
|---|---|---|
| Single Bed | Approx. 36 × 75 inches | Single Bedsheet |
| Double Bed | Approx. 48 × 75 inches | Double Bedsheet |
| Queen Size | Approx. 60 × 78 inches | Queen Size Bedsheet |
| King Size | Approx. 72 × 78 inches | King Size Bedsheet |
Tip: Always check the actual dimensions of your mattress before purchasing a bedsheet, especially if your mattress is extra thick or has a topper.
How Do I Know What Size Bedsheet I Need?
The easiest way to find the right bedsheet size is to measure your mattress.
You need three measurements:
1. Mattress length
Measure from the head of the mattress to the foot.
2. Mattress width
Measure from one side to the other.
3. Mattress depth
Measure from the top of the mattress to the bottom. This is especially important when choosing a fitted sheet.
Once you know these measurements, you can choose a bedsheet that provides enough coverage without looking oversized.
Why Mattress Depth Matters
Two mattresses can have the same length and width but require different sheets because their thicknesses are different.
For example, a thick mattress with a mattress topper may need a deep pocket fitted sheet, while a standard mattress may work perfectly with a regular fitted sheet.
What Size Sheet Do I Need for a King Size Bed?
If you have a king size mattress, you’ll generally want a king size bedsheet designed to provide sufficient coverage across the entire mattress and sides.
For larger beds, look for sheets with generous dimensions so you have enough fabric to tuck underneath the mattress.
At Veloura, our king size bedsheets are 108 × 108 inches, giving you plenty of coverage for a spacious bed.
A king size bedsheet is a great choice if you have:
- A large king size mattress
- A thicker mattress
- A mattress topper
- A bed where you prefer more fabric to tuck in
- A spacious bedroom with a statement bed
What Size Sheet Do I Need for a Queen Size Bed?
A queen size bed typically requires a queen size bedsheet that comfortably covers the mattress and provides enough drop on the sides.
When shopping for a queen size bedsheet, don’t only look at the words “queen size.” Check the actual sheet dimensions listed by the brand.
This is particularly important if your mattress is thicker than standard.
What Size Sheet Do I Need for a Double Bed?
A double bed is smaller than a queen or king size bed, so choosing a sheet specifically designed for a double bed can help prevent excessive fabric from hanging over the sides.
Before buying, measure your mattress and compare the dimensions with the bedsheet size chart provided by the brand.
What Size Sheet Do I Need for a Single Bed?
For a single bed, choose a single bedsheet that provides enough width and length to cover the mattress with some extra fabric for tucking.
Single bedsheets are ideal for:
- Single beds
- Children’s beds
- Guest rooms
- Smaller bedrooms
- Dorm rooms
Flat Sheet vs Fitted Sheet: Which One Should I Buy?
One of the biggest differences when shopping for bedsheets is whether you want a flat sheet or fitted sheet.
Flat Bedsheet
A flat bedsheet is a large rectangular piece of fabric that sits over the mattress. You can tuck the sides underneath the mattress.
Flat sheets are versatile because they can accommodate different mattress depths, provided the sheet is large enough.
Fitted Bedsheet
A fitted sheet has elasticated corners designed to fit around your mattress.
The biggest advantage of a fitted sheet is that it stays in place while you sleep.
However, you need to pay attention to mattress depth and pocket size when purchasing one.
How Much Bigger Should a Bedsheet Be Than the Mattress?
For a flat bedsheet, you generally want additional fabric on each side of the mattress so that you can tuck it underneath comfortably.
A useful approach is:
Sheet width = mattress width + extra fabric for both sides
Sheet length = mattress length + extra fabric for the head and foot
The amount of extra fabric you need depends on how much you prefer to tuck in and how thick your mattress is.
If you love a neat, hotel-style bed, choosing a slightly more generous sheet can make styling your bed much easier.
Common Bedsheet Buying Mistakes
1. Buying Based Only on “King” or “Queen”
Different brands can have different measurements for the same bed category.
Always check the actual bedsheet dimensions.
2. Ignoring Mattress Thickness
A thick mattress requires more fabric, especially if you want to tuck your bedsheet underneath.
3. Forgetting About Mattress Toppers
If you use a mattress topper, remember to include its thickness when measuring your bed.
4. Choosing a Sheet That Is Too Small
A bedsheet that barely covers the mattress can constantly come loose and make your bed look untidy.
5. Not Checking the Fabric
Size isn’t the only thing that matters. Look for comfortable, breathable and quality fabric that feels good against your skin.
How to Measure Your Mattress for a Bedsheet
Don’t have a measuring tape? You can still estimate your bed size, but for the best fit, measuring is recommended.
Simply:
Step 1: Remove your existing bedsheet.
Step 2: Measure the mattress from left to right.
Step 3: Measure from the head to the foot.
Step 4: Measure the mattress thickness.
Step 5: If you use a mattress topper, include its thickness.
Step 6: Compare your measurements with the brand’s bedsheet size chart.
And that’s it—you now know exactly what size sheet you need.
What Is the Best Bedsheet Material?
Once you’ve figured out the correct size, the next question is usually: which fabric should I choose?
For everyday use, cotton bedsheets are a popular choice because cotton is soft, breathable and comfortable.
If you’re looking for a premium sleeping experience, pay attention to factors such as:
- Fabric composition
- Thread count
- Weave
- Breathability
- Softness
- Colour quality
- Mattress fit
- Wash durability
At Veloura, we focus on creating premium bedding designed to bring a comfortable, elevated feel to your bedroom.
