Are you in the market for a new mattress? With so many options out there, it can be tough to know where to start — especially when deciding between a full and king size. Whether you need something that fits a smaller room or you’re looking for a bed with plenty of room to stretch out, this guide will help you weigh the pros and cons of both sizes.
Mattress Dimensions
When it comes to choosing between a king and full-size mattress, the biggest difference is their dimensions:
- A full mattress measures 54 inches in width and 75 inches in length.
- A king mattress is much larger, boasting a width of 76 inches and a length of 80 inches.
To put it in perspective, a king mattress is a whopping 22 inches wider and 5 inches longer than a full. While the full takes up less space and is easier to move, the king offers more room to stretch out and get comfortable.

Let’s break down how much sleeping space you’ll get with each option and how that can affect your snooze time.
Full Mattress Sleeping Space
A full mattress gives solo sleepers plenty of room to stretch out and get cozy. It’s 54 inches wide, so it’s a step up from a twin, making it perfect if you like a bit more space to move around. However, it can feel cramped for couples, especially if one of you tosses and turns at night. Ultimately, full mattresses are great for teens, guest rooms or anyone who likes their own sleep zone without taking up too much space.
King Mattress Sleeping Space
A king mattress is your go-to if you want maximum comfort and space to relax. At 76 inches wide, it’s got loads of room — perfect for couples who like their personal space or for those nights when the kids or pets sneak into bed. With all that extra space, you can sleep however you like — spread out or curled up — and still have room to spare.

Room Size Considerations
Before you make your decision, measure your bedroom. After all, you’ll want your mattress to fit comfortably without making your room feel cramped. Here’s what to consider for each option:
Full Mattress Room Size
For a full mattress, you’ll want a bedroom that’s at least 10 feet by 10 feet. This gives you enough space for the bed itself, plus some wiggle room for nightstands and walking around comfortably. It’s a great option for smaller bedrooms or guest rooms where space is at a premium.
King Mattress Room Size
Being the roomier option, a king mattress needs more space to shine, so aim for a bedroom that’s at least 12 feet by 12 feet. This allows for the larger bed and still leaves room for other furniture and easy movement. It’s perfect for master bedrooms or larger spaces where you want the bed to be a grand centerpiece. Also, don’t forget about measuring doorways and staircases, especially if you’re opting for a king. The last thing you want is to find out your new mattress won’t make it up the stairs or through the bedroom door on delivery day.
Price Differences
When choosing between a full and king mattress, price is definitely something to consider. Let’s break down how each option compares when it comes to cost.
Full Mattress Price
A full mattress is generally more affordable than a king. Since it’s smaller, it uses fewer materials, which brings the price down. This makes a full mattress a great choice if you’re on a budget or shopping for a guest room, a kid’s room or a smaller space. Plus, you’ll save a bit on accessories like sheets, mattress protectors and bed frames, which are usually cheaper in full sizes.
King Mattress Price
King mattresses are larger, which means they’re usually more expensive than full mattresses. But if you’re looking for luxury, the extra cost might be worth it! You’re not just paying for the larger size but also the added comfort and space, especially if you share your bed or love to sprawl out. Keep in mind that bedding and bed frames for king-sized mattresses also tend to cost more.
