Finding the perfect mattress size is crucial to ensure that there is ample sleeping space for the individual and their partner (if applicable). It’s equally important to ensure that the mattress fits comfortably within the bedroom, leaving room for movement and relaxation.

We’re here to help you navigate the standard mattress sizes, how they compare, and how to choose the best fit for your needs. Keep reading to find out which mattress size is the right one for you!

Mattress Sizes

Though there are some specialty sizes, let's focus on the six standard mattress sizes:

These sizes are what you'll typically encounter when shopping either online or in a store. There may be slight variations of an inch or two, but overall, mattress sizes are fairly consistent. Please note that these sizes are based on US measurements, and names/sizes may differ in other countries.

Twin Size Mattress & Dimensions

A Twin mattress measures 38” x 75”, making it the smallest standard size available. Twin mattresses are ideal for children or adults who are smaller in stature or those living in compact spaces.

A Twin mattress is not recommended for individuals sharing the bed with a partner.

Who will prefer the Twin?

• Smaller adults or children: Twin beds are typically the next step after a crib mattress, measuring 38” x 75” (sometimes 74”).
• Those needing a bed for a small room: Twin beds work well as a replacement for a crib or in smaller spaces, like a child’s room or shared bedrooms.
• Budget-conscious shoppers: Twin beds are the most affordable option, often chosen by people transitioning from a crib. While some may skip a Twin and opt for a Full/Double or Twin XL, the Twin remains the most budget-friendly choice.

Twin XL Size Mattress & Dimensions

A Twin XL mattress measures 38” x 80”. This mattress is 5” longer than a Twin, but the width remains the same, making it perfect for taller children or adults with limited bedroom width.

The Twin XL is a common choice for college dorms.

Who will prefer the Twin XL?

• People seeking a bed for a young adult or college student: The Twin XL offers 5” more length than the Twin, making it a great option for growing teens and adults, and it’s popular in dorm rooms.
• Those needing a bed for a smaller room: The Twin XL fits well in secondary bedrooms, saving space for other furniture while offering extra length compared to a Full.
• Shoppers on a budget: The Twin XL is an affordable upgrade from the Twin without jumping to the higher price point of a Full mattress.

Full Size Mattress & Dimensions

A Full-size mattress measures 54” x 75”. This mattress is 16” wider than a Twin, but it shares the same length. It’s perfect for someone sleeping solo who wants a bit more room, or for couples of smaller stature.

Queen Size Mattress & Dimensions

A Queen mattress measures 60” x 80”. Larger and longer than a Full, a Queen offers extra space, making it ideal for individuals who enjoy more room or for most couples.

A Queen mattress is a great option unless your room can accommodate something larger or if you need even more surface area to spread out.

King Size Mattress & Dimensions

A King mattress measures 76” x 80”. A King is the same length as a Queen, but it’s 16” wider. Couples looking for plenty of space may prefer a King, but for a single person, it may feel too large.

Who will prefer the King?

A King mattress is best suited for couples. Essentially, it’s as if each person has their own Twin XL bed. A King mattress offers 8” more space per person than a Queen, making it an excellent choice for Master Bedrooms.

California King Size Mattress & Dimensions

A California King mattress measures 72” x 84”. It is 4” longer but 4” narrower than a standard King mattress.

Many people wonder whether to go with a King or California King mattress. The King is wider, while the California King is longer. A King is great for couples who need more space, while the California King is perfect for taller individuals.

What’s the Difference Between a King and California King Mattress?

A California King is longer and narrower than a King. It measures 72” x 84” compared to the King’s 76” x 80”.

Who will prefer the California King?

• People looking for a Master Bedroom mattress with more length than width will find the California King appealing.
• Sleepers with extra budget and preference for additional length can opt for a California King, but keep in mind, their King-size accessories (sheets, frames) won’t be compatible.

Mattress Size Comparisons

Often, it comes down to deciding between two sizes. Should a taller person go for a King mattress, or will a Queen suffice? Is a Full mattress enough for a smaller couple, or will they need to go for a Queen?

Let’s compare a few common sizes to make it easier for shoppers:

• Twin vs. Twin XL: A Twin mattress is smaller than a Twin XL and is better suited for smaller children. Twin XLs provide more length for taller individuals.
• Twin XL vs. Full: Twin XLs offer a good fit for smaller adults or rooms, while Full mattresses are more appropriate for regular-sized adults and smaller couples.
• Full vs. Double: A Full and Double are the same size (54” x 74”).
• Full vs. Queen: A Full is a great choice for solo sleepers. Queen mattresses offer more space and are ideal for larger individuals or couples.
• Queen vs. King: A Queen works well for single people or couples with smaller bedrooms. A King provides more space for larger couples.
• King vs. California King: A King is wider and more suitable for larger couples, while a California King is ideal for taller individuals or those with narrow, long rooms.

Non-Traditional Mattress Sizes

While we’ve covered the most common sizes, there are also a few less traditional options:

Which Mattress Size is Best for Me?

Before committing to a purchase, it’s important to measure the bedroom to ensure the mattress will fit. Here are a few tips:

• Measure the Bedroom: Knowing your available space is crucial before deciding on a mattress size. Use a tape measure to check the dimensions of your room and talk to your leasing office (if applicable) about room sizes.
• Consider the Trial Period & Warranty: If shopping online, it’s a good idea to choose a mattress with a long trial period. This gives you time to determine if the size is right for you and whether it’s comfortable.

Final Thoughts

Choosing the right mattress size is largely based on personal preference. Consider this guide carefully to ensure that your mattress suits your specific needs and provides a good night’s sleep.
