What Are The Measurements Of a Double Mattress? Size Guide & FAQs
If you’re asking “What Are The Measurements Of a Double Mattress”, you’re probably trying to work out if it will fit your bedroom, your bed frame, or even your bedding. This guide explains standard double mattress dimensions, common variations, and what to check before you buy or set one up.
What Are The Measurements Of a Double Mattress in Standard Sizing?
In many regions, a standard double mattress (also often called a full mattress) typically measures:
- 135 cm x 190 cm
- Approximately 54 inches x 75 inches
These are the most commonly accepted measurements of a double mattress in standard sizing. However, there are some important variations to understand.
Are Double Mattress Measurements the Same Everywhere?
Not always. When people search “What Are The Measurements Of a Double Mattress”, they often discover that sizes can vary slightly by country and manufacturer.
Common regional patterns include:
- In some regions, double and full are used interchangeably for 135 x 190 cm (54" x 75").
- Some brands may label a slightly different size as “double,” especially in custom or specialty ranges.
- Tolerance of a few centimeters (or about an inch) can occur because of different manufacturing methods and materials.
Because of these small variations, it’s helpful to check the exact measurements listed on the product label rather than relying only on the name “double.”
How Does a Double Mattress Compare to Other Mattress Sizes?
Understanding where a double fits in the size lineup can help you decide if it’s right for your space and sleeping needs.
A double mattress is generally:
- Wider than a single/twin – giving more room for one sleeper, or a snug fit for two.
- Narrower than a king or queen – more compact for smaller bedrooms or guest rooms.
- Shorter than many “long” or “XL” versions – which can matter for taller sleepers.
A simple comparison (approximate):
| Size Name | Typical Width x Length (cm) | Typical Width x Length (inches) |
|---|---|---|
| Single/Twin | 90 x 190 | 36" x 75" |
| Double/Full | 135 x 190 | 54" x 75" |
| King (varies) | 150–180 x 200 | 60–72" x 79–80" |
Note: Exact dimensions can differ slightly by region and manufacturer.
Why Do Double Mattress Measurements Matter?
Knowing the measurements of a double mattress helps with:
- Room planning – Ensuring you can walk around the bed, open doors, and access storage.
- Bed frame compatibility – A mismatch can lead to gaps, overhang, or poor support.
- Bedding fit – Fitted sheets, mattress protectors, and toppers need the correct size.
- Comfort for sleepers – Double mattresses can feel spacious for one person but compact for two, especially if both sleepers move a lot.
A double mattress is often chosen for:
- Smaller main bedrooms
- Guest rooms
- Older children or teenagers who’ve outgrown a single
Do All Double Mattresses Have the Same Height?
When people ask “What Are The Measurements Of a Double Mattress”, they often focus on length and width, but height (thickness) also matters.
Mattress height can vary widely, for example:
- Shallower profiles: around 15–20 cm (6–8")
- Standard profiles: around 20–30 cm (8–12")
- Taller profiles: sometimes 30 cm (12") or more
Height differences can affect:
- How easily you can get in and out of bed
- How your fitted sheets and mattress protectors fit
- The overall look of your bed with a frame and base
How Do I Measure My Double Mattress Correctly?
To be sure your mattress matches standard double measurements:
- Remove all bedding – including toppers and protectors.
- Measure width – from side edge to side edge, at the widest point.
- Measure length – from head to foot, along the center line.
- Measure height – from the bottom surface to the highest point of the sleep surface.
Tip: 📏 Measure in both centimeters and inches if you’re comparing products from different regions or retailers.
Will a Double Mattress Fit My Existing Bed Frame and Bedding?
To avoid fit issues:
- Check your bed frame’s inner dimensions, not just the outer size.
- Look at your current fitted sheets and note their labeled size and maximum depth.
- If you’re moving from a different size (for example, from single to double), be aware that pillows stay the same size, but most other bedding items will not.
When in doubt, match the mattress dimensions to the frame and bedding measurements, not just the size name.
