When choosing a bed, the size of your mattress affects your sleep comfort, bedroom layout, and lifestyle. That’s why knowing the difference between mattress sizes is an important part of selecting the right one that fits your space and preferences.
In this blog post, we’ll focus on smaller mattress sizes that are perfect for furnishing a small bedroom. We’ll compare the three quarter, twin, and full-sized bed, talking about which one works best for your situation.

Mattress Sizes Compared: Twin vs. ¾ vs. Full
Whether you’re restoring an antique bed frame or outfitting a small guest bedroom, you’ll likely encounter these bed sizes.
The twin bed is the smallest out of these three mattress sizes, making it quite narrow in comparison. This compact bed size is ideal for kids who don’t need as much space as an adult. Meanwhile, a full or double bed offers a lot more room, allowing a solo-sleeper to stretch out comfortably. Although a full mattress can accommodate two people, it definitely won’t be as roomy as a larger bed size like a queen, king, or even an oversized king mattress.
The ¾ bed serves as a good mid-sized option. It’s wider than a twin but narrower than a full bed. Also known as a small double, this mattress size is essential for antique bed frames.
Here’s an easy table that summarizes the sizes of each mattress and where it’s commonly found:
Bed Size | Width (inches) | Length (inches) | Commonly Used in |
Twin | 38" | 75" | Children’s rooms, college dorms, and bunk beds |
3/4 | 48" | 75" | Antique Victorian and Edwardian bed frames, older European homes, boutique hotels |
Full | 54" | 75" | Apartments with smaller bedrooms |
Both the twin and full mattress are a lot more common than the three quarter bed. That’s because 3/4 mattress size was not adopted by modern mattress manufacturers.
Finding a three quarter mattress for your heirloom bed or specially made bed frame can be a challenge. And, this is where custom mattress manufacturers come in. With the help of a reputable mattress maker, you can order a bespoke three quarter mattress that fits your unique bed frame perfectly.
How to Choose the Best Bed Size for Your Needs
Choosing the right bed depends on your lifestyle, room size, and budget. Here are a few questions you need to ask yourself:
Do I need to save space?
Is this for a child, teen, or adult?
Is this for a couple or shared use?
Do I move around a lot in my sleep?
Do I want off-the-shelf bedding options?
You should get a twin bed if you need to save space and if a child or teen will be using the bed. A twin sized mattress is also standard size, making it easy for you to purchase bedding.
If you want space efficiency without giving up on sleep comfort, the three quarter bed will be a great choice. This mattress size gives children, older teens, and adults enough space to stretch out. A three quarter mattress is also a must-have if you’re restoring an antique bed frame.
Finally, the full bed is another standard size that offers more room. However, the downside is that it can make small rooms feel even tinier, since it’s bulky. A full mattress is a good choice for people who move around a lot in their sleep. In a pinch, it can also accommodate couples.
Custom Three Quarter Beds Can Be a Great Fit for Your Home
While twin beds are great for simplicity and full beds offer more room, three-quarter beds offer you the best of both worlds.
Whether you’re looking to restore your antique bed frame or furnish your guest bedroom with a bed that’s just right, the three quarter mattress is a fantastic choice. Since this mattress size isn’t generic, you’ll need to go for a custom option.
