If you’re looking for a balance between affordability and space, a Double bed is one of the most popular choices in Johannesburg. But before buying, it’s important to understand exactly how big a Double bed is—and whether it’s the right fit for your room and lifestyle.

This guide covers double bed dimensions in South Africa, how they feel in real life, and whether this size is suitable for one or two people.

What Size Is a Double Bed in CM?

A standard Double bed in South Africa measures:

Width: 137 cm
Length: 188 cm

If you’re searching for “double bed size in cm” or “double bed dimensions South Africa”, this is the standard size used across most manufacturers.

Each person gets roughly 68.5 cm of sleeping space, which is enough for two people—but can feel tight depending on your sleeping habits.

Double Bed Dimensions (Including Extra Length)

Double beds are also available in extra length options:

Standard Double Bed: 137 cm x 188 cm
Extra Length Double Bed: 137 cm x 200 cm

Extra length is ideal if:

You are taller than average
You want extra legroom
The bed will be used long-term

How Big Is a Double Bed in Real Life?

A Double bed sits right in the middle—it’s larger than a Three Quarter, but smaller than a Queen.

Suitable for: One adult (very comfortable)
Can fit: Two adults
Limitation: Space can feel restricted for couples

If you’re wondering “is a double bed big enough for two?”—the answer is yes, but many couples eventually prefer upgrading to a Queen for more space.

Double Bed vs Queen Bed (Should You Upgrade?)

This is one of the most common comparisons when buying a bed.

Double Bed: More affordable, space-saving
Queen Bed: More comfortable for couples, wider sleeping space

Choose a Double bed if:

You’re working with a smaller bedroom
You want a more budget-friendly option
You don’t mind sleeping closer together

Consider a Queen if:

You want more personal space
You’re a restless sleeper
The bed will be used long-term by two people

What Size Room Do You Need for a Double Bed?

A Double bed works well in:

Small to medium bedrooms
Apartments and townhouses
Guest rooms

To keep your room comfortable, allow at least 60–70 cm of space around the bed for movement.

In many Johannesburg homes, a Double bed is often the best compromise between space and affordability.
