What Size Is a Single Bed in South Africa?

A standard Single bed in South Africa measures:

Width: 91 cm
Length: 188 cm

This makes it the smallest standard bed size available, ideal for one person.

If you’re searching for “single bed dimensions in cm” or “how big is a single bed”, this is the standard size you’ll find across most manufacturers.

Single Bed Dimensions (Including Extra Length)

In addition to the standard size, Single beds are also available in extra length:

Standard Single Bed: 91 cm x 188 cm
Extra Length Single Bed: 91 cm x 200 cm

An extra-length single bed is a good option if:

You are taller than average
You want extra legroom
A growing teenager will use the bed

How Big Is a Single Bed in Real Life?

While dimensions are helpful, it’s just as important to understand how a Single bed feels in everyday use.

Suitable for: One child or one adult
Space: Compact and space-saving
Not suitable for: Two adults sharing

A Single bed works well in smaller Johannesburg rooms where space is limited, but most adults may find it restrictive for long-term use.

What Size Room Do You Need for a Single Bed?

One of the most common questions is: “will a single bed fit in a small room?”

Single beds are ideal for:

Small bedrooms
Kids’ rooms
Guest rooms
Studio apartments

As a general guide, you should leave at least 60 cm of walking space around the bed to keep the room functional and comfortable.

Single Bed vs Three Quarter Bed (Quick Comparison)

If you’re unsure whether a Single bed is big enough, you may also be considering a Three Quarter bed.

Single Bed: 91 cm wide (more compact and affordable)
Three Quarter Bed: 107 cm wide (more space for one adult)

If you want more sleeping space without going too large, a Three Quarter bed is often the better choice.

Bed Height and Base Considerations

While the width and length are standard, the overall height of a Single bed can vary depending on:

Mattress thickness: Typically ranges from 15 cm to over 30 cm
Base height: Usually around 20–30 cm
Leg height: Can vary depending on the base style

Lower beds are often more affordable, while thicker mattresses and higher bases are usually associated with more premium comfort. Be sure to check out what mattress fits a single bed to make sure you have the correct measurements
