Before we dive into what size mattress is best for you, it’s important to understand the standard mattress sizes available in the U.S. Here's a quick rundown of each mattress size along with its dimensions and who it’s ideal for:
- Twin (38” x 75”): Twin mattress measurements are perfect for a single sleeper mattress. Typically, homeowners choose twin mattresses for kids, smaller rooms, or guest spaces. It’s an affordable option when you need space-saving solutions.
- Twin XL (38” x 80”): Similar to a Twin but 5 inches longer, this size is ideal for taller individuals or college dorm rooms where space is limited.
- Full (54” x 75”): Full size mattress dimensions are a great choice for single adults who want more space than a Twin but don’t have room for a larger mattress. They also work well for smaller guest rooms.
- Queen (60” x 80”): The most popular size, the 60” x 80” Queen mattress size is perfect for couples or individuals who want extra room to stretch out. It offers a good balance of comfort and room efficiency.
- King (76” x 80”): King mattress dimensions are designed for couples who want ample space to spread out or single sleepers who enjoy a spacious bed. This is ideal for larger rooms with plenty of space.
- California King (72” x 84”): The California King mattress size is longer and narrower than a King, making it perfect for taller individuals or those who want the extra length for added comfort while sleeping.
Check out this mattress size chart:
| Mattress Size | Dimensions (inches) | Best For |
|---|---|---|
| Twin | 38" x 75" | Kids, bunk beds, or small guest rooms |
| Twin XL | 38" x 80" | Taller teens, college dorms |
| Full (Double) | 54" x 75" | Solo sleepers who want more room |
| Queen | 60" x 80" | Couples or single sleepers who like extra space |
| King | 76" x 80" | Couples who want maximum sleeping area |
| California King | 72" x 84" | Taller sleepers or those who prefer extra legroom |
These sizes are standard in the U.S., but it’s important to remember that variations may exist internationally—especially in terms of length and width.

Room Size vs. Mattress Size: Finding the Right Fit
While mattress size is important for comfort, room size is just as critical when choosing the right mattress. For example, Queen is the most common mattress size, but Twin and Twin XL are the best small room mattress sizes.
A mattress that's too big for your room can make the space feel cramped, while one that's too small can leave the room feeling sparse. It’s wise to leave a 30” to 36” walkway around your bed. Here’s how you can match a mattress size with room dimensions:
- Twin: Best for rooms that are 8’ x 10’ or smaller. A Twin works in tight spaces where you need to save floor space.
- Twin XL: Ideal for rooms around 8’ x 10’. It's often used in dorms where both space and comfort are essential.
- Full: Works well in rooms 10’ x 10’ or larger. It’s a good size for a child or teenager’s room or a small guest room.
- Queen: Fits best in rooms 10’ x 12’ or larger. It’s the ideal size for most master bedrooms and guest rooms, offering a comfortable amount of space without overwhelming the room.
- King: Perfect for rooms 12’ x 12’ or bigger. It’s a luxurious choice for couples who need space to stretch out, but you’ll need a bigger room to avoid a cramped feel.
- California King: Works best in rooms that are 12’ x 12’ or larger. It’s the longest mattress, so it's great for tall individuals, but it requires a spacious room.
Before you make a final decision, measure your bedroom to ensure the mattress you choose will allow for adequate walking space and the proper placement of other furniture.

Sleeping Solo, As a Couple, or With Pets? Find Your Size
The number of sleepers and your lifestyle also impact the ideal mattress size. Whether you're sleeping solo, with a partner, or sharing your bed with pets, here are the mattress sizes that best fit different sleeping arrangements:
- Single Sleepers: If you're sleeping alone, a Twin or Twin XL might be the best option. A Full can provide more room if you like extra space, especially for taller individuals who might need the extra length of a Twin XL. However, if you have a spacious primary bedroom all to yourself, upgrade to a Queen or King to fill the space and add a touch of luxury.
- Couples: What is the best mattress size for couples? Couples often opt for a Queen, as it provides enough space without being overwhelming in the room. However, if you and your partner both love to spread out, a King mattress is the ideal choice. The California King can be a good alternative for taller individuals who need more length for a comfortable night’s sleep.
- Families or Pet Owners: For those who co-sleep with kids or pets, a King or California King will give you all the room you need to spread out. If you have multiple pets, consider a King for extra space for everyone.
Taller sleepers may prefer a Twin XL, California King, or even a King, as these options provide more legroom than standard sizes.

Why Trust Urner's and Urner's Mattress?
Urner’s started on the back of a bicycle - yup! A bicycle! David E. Urner, a local high school teacher, who spent his summer months selling Wear Ever cookware off the back of a bicycle (think 100+ degrees). David teamed up with another local teacher, Errol P. Janes to create “a new type of store – one that would cater exclusively to providing an easier way of living for the women of Kern County”, and on September 19, 1919, Home Appliance Store was opened to the public. The store boasted a rather impressive selection of “modern” appliances, including a washing machine, a freezer, a gas range, an automatic dishwasher, and an assortment of small appliances. Since then, Urner’s has expanded selections to appliances, furniture, mattresses and cabinetry!
For nearly one century, the Urner family and Urner’s business have both been an integral part of Bakersfield and Kern County, with contributions to community (Better Business Bureau, Sister City Projects, Bakersfield Symphony), charity (Ronald McDonald House, St. Jude’s Dream Home, House of Hope) and education (CSU Bakersfield, Ray Dezember Leadership Development Center.
