What Are The Dimensions Of a Double Mattress? A Practical Size Guide

If you’re asking “What Are The Dimensions Of a Double Mattress”, you’re likely trying to work out if it will fit your bedroom, your bed frame, or your existing bedding. This guide breaks down standard measurements, regional differences, and how a double compares with other mattress sizes so you can plan with confidence.

What Are The Dimensions Of a Double Mattress in Most Regions?

In many places, a double mattress is the same as a full-size mattress. The typical dimensions are:

• 135 cm x 190 cm
• 54" x 75" (inches)

These measurements are considered standard in many markets, but there can be small variations depending on the manufacturer.

Key point: A double mattress is generally about 135 cm wide and 190 cm long, making it wider than a single but smaller than a queen.

Do Double Mattress Dimensions Vary by Country?

Yes. When people ask “What Are The Dimensions Of a Double Mattress”, part of the confusion comes from regional naming differences.

Here’s a simple reference:

Not every region uses all these terms, and some stores may label sizes slightly differently. Checking the exact measurements in centimeters or inches is more reliable than going by the name alone.

How Does a Double Mattress Compare to Other Sizes?

Understanding how a double fits into the overall size range can help you decide if it’s suitable for your needs.

Double vs Single / Twin

• A standard single or twin is usually about 90 cm x 190 cm (36" x 75").
• A double is wider, offering more space for a solo sleeper or a snug fit for two.

Use case: A double mattress often works well for single adults, teenagers, or a smaller guest room.

Double vs Queen

• A queen is usually around 150 cm x 200 cm (60" x 80").
• Compared to a double, a queen is generally about 15 cm (6") wider and 10 cm (4–5") longer.

Use case: Many couples prefer a queen or larger for more personal space, while a double can work when room size is limited.

How Much Space Do You Need Around a Double Mattress?

When thinking beyond “What Are The Dimensions Of a Double Mattress”, it helps to consider the overall room layout.

To move comfortably around the bed, many people like to allow:

• At least 60–75 cm (24"–30") of clear space on each accessible side
• Enough length at the foot of the bed for walking or storage

For example, if your double mattress is 135 x 190 cm, a simple layout might work well in a bedroom that’s at least around:

• 2.5 m x 3.0 m (8' x 10'), depending on furniture placement

This is not a strict rule, but a helpful starting point when planning.

Will a Double Mattress Fit My Existing Bed Frame and Bedding?

Bed frames

To avoid gaps or overhangs:

• Check the internal dimensions of your bed frame (where the mattress sits).
• Compare those with the exact stated size of the double mattress.
• Allow for a small tolerance, as some frames are designed slightly larger than the mattress size.

Bed linens and accessories

For a standard double mattress at 135 x 190 cm / 54" x 75":

• Look for “double” or “full” size fitted sheets and mattress protectors.
• Deeper mattresses may require “deep pocket” or “extra deep” sheets so they don’t slip off.
• Comforters, duvets, or blankets marked as double/full are usually sized to give some overhang on the sides.

What Should You Consider Before Choosing a Double Mattress Size?

When deciding if a double is right for you, think about:

• Who will use it:

  • Solo sleeper, child, teenager, or occasional guests
  • Two adults may find it cozy or slightly tight, depending on preferences

• Sleeper height:

  • At about 190 cm / 75" long, taller individuals may want a longer option (often labelled as “queen” or similar, depending on region).

• Room size and furniture:

  • Dressers, wardrobes, and bedside tables can limit how large a mattress feels comfortable in the room.

• Future flexibility:

  • If you might rearrange rooms or move, a double mattress can be relatively easy to fit into different spaces.
