✅ What Are Full Size Mattress Dimensions?
The standard full size mattress dimensions are:
📏 54 inches wide by 75 inches long
(That’s about 137 cm by 191 cm)
This size is sometimes called a double bed, although it’s not really double the size of a twin—it’s just a bit wider.
🛏️ Real-Life Example: How a Full Size Mattress Fits in a Room
Let’s say you live in a small apartment and your bedroom is 10 feet by 10 feet. A full size mattress would fit just fine, leaving room for a small nightstand, dresser, and space to walk around.
Here’s a simple case study:
📚 Case Study: Emma’s First Apartment
Emma, a 22-year-old college graduate, moved into a studio apartment. She wanted a bed that was bigger than a twin but still space-saving. A full size mattress gave her enough room to stretch while still fitting perfectly into her 10×10 bedroom.
It’s great for growing teens who need more space than a twin.
✅ Single Adults
Perfect for someone living alone who wants a comfortable bed without using up all their room space.
✅ Guest Rooms
If you’re setting up a guest room, a full bed fits the bill. It provides enough comfort without needing a giant space.
🚪 Will a Full Size Mattress Fit My Room?
Use this simple method:
Measure your room.
Leave at least 2 feet of walking space on each side of the bed.
Add space for furniture like nightstands or dressers.
For example, if your room is 9×9 feet, a full size bed will fit—just keep furniture to a minimum.
🧠 Tips to Remember When Shopping for a Full Size Mattress
Check the material: Memory foam is soft and forms to your body. Innerspring has more bounce.
Test before you buy: Lie on it in-store if possible.
Check return policies when buying online.
Use a mattress protector to make it last longer.
Measure hallways and door frames to ensure it fits into your home.

📦 Mattress in a Box: Is It Available in Full Size?

You can find them for as low as $200 for budget models. Higher-end models may cost up to $1,000 or more depending on brand and features.
🔁 Can Two People Sleep on a Full Size Mattress?
