The Overview of King Single and Single Size
Both are space-saving, but the single is the smallest adult bed (great for tight spots), while the king single offers more stretching room without the bulk of a double. The key question for king single vs single: extra comfort or maximum space savings?
King Single Size: What You Need to Know
Key Features

- Standard Australian dimensions: 107cm wide x 203cm long (15cm wider and 15cm longer than a single bed).
- Same length as a queen or king bed (203cm), suitable for tall sleepers.

King Single vs. Single: Which One is Best for You?
Now that we’ve covered each size individually, let’s compare king single vs single head-to-head to help you decide which one is right for your needs.
We’ll break down the key differences in size, comfort, space, cost, and who each size is best for.
1. Size Comparison (King Single vs Single)
The king single is 15cm wider and 15cm longer than the single bed. That extra space might seem minimal, but it makes a huge difference in comfort.
If you’re tall (over 180cm), the king single’s extra length will prevent your feet from hanging off the edge, while the extra width gives you room to stretch out. The single bed is better for smaller spaces, but it’s too short for most tall adults.
2. Comfort Comparison (King Single vs Single)
When it comes to king single vs single, the king single is hands down more comfortable for adult sleepers. The extra width and length mean you can move around at night without feeling cramped, sleep with pillows or a pet, and wake up without feeling stiff.
The single bed is comfortable for kids and small adults, but it can feel restrictive for anyone who likes to stretch out. According to a study by the National Sleep Foundation, having enough space to move during sleep is key to better sleep quality—so the king single’s extra space can lead to more restful nights.
3. Space Efficiency (King Single vs Single)
The single bed is the clear winner for small spaces. It’s compact and takes up less floor space, making it perfect for tiny bedrooms, studio apartments, or kids’ rooms.
The king single is slightly larger, so it’s better for bedrooms that have a bit more space (at least 8–10 square meters). If you have a small room but still want extra comfort, the king single is a better choice than a double bed, as it’s more space-saving.
4. Cost & Longevity Comparison (King Single vs Single)
Single beds are 10–20% cheaper than king singles (mattresses, frames, bedding included). King singles are a better long-term investment—they fit teens into adulthood, while singles need replacing as kids grow. Choose a single for budget/tiny spaces; king single for comfort/longevity.
FAQs
Q: What’s the difference between a king single vs single?
A: The main difference is size. A single bed is 92cm x 188cm, while a king single is 107cm x 203cm—15cm wider and 15cm longer. The king single offers more space and comfort, while the single is more compact and affordable.
Q: Is a king single bed bigger than a single bed?
A: Yes! A king single is both wider and longer than a standard single bed. It’s designed to give solo sleepers more room to stretch out without being as big as a double bed.
Q: Can an adult sleep comfortably on a single bed?
A: It depends on the adult’s size and sleeping habits. Smaller adults (under 165cm) who don’t move around much can sleep comfortably on a single bed, but taller or restive sleepers will likely feel cramped. A king single is a better choice for most adults.
Q: Is a king single bed suitable for a teen?
A: Absolutely! King single beds are perfect for teens—they’re long enough to accommodate their growing height (same length as a queen bed) and wide enough to give them space to move around. They’re a great long-term option that will last through their teen years into adulthood.
Q: Which is more affordable: king single vs single?
A: The single bed is more affordable. Single mattresses, bed frames, and bedding cost less than king single options, making them a great choice for budget shoppers. King singles are slightly more expensive but offer more comfort and longevity.
Choosing between king single vs single is simple: opt for a king single for extra space (teens/adults), or a single bed for budget/tiny spaces. Both work for single sleepers—your needs will guide you.
