Double Bed Size Guide: Dimensions, Measurements and What Fits in Australia
Buying a new bed often turns into a frustrating guessing game when you are trying to balance bedroom space, comfort, and actual mattress dimensions. Many Australian shoppers order a bed online only to find that it blocks the wardrobe doors or leaves no room for a bedside table. Knowing the exact double bed size and checking accurate double bed dimensions and measurements before you buy prevents costly mistakes. Whether you are checking the ideal double mattress size for a compact apartment, upgrading a teenager's bedroom, or setting up a comfortable guest room, understanding standard measurements is the key to getting your bedroom layout right.
Shop with confidence: Check the standard double bed size (about 138 cm × 188 cm) and explore Levede’s double mattress collection before you buy.
What Is a Double Bed Size in Australia?
In Australia, a standard double bed size measures approximately 138 cm wide by 188 cm long. In other words, the standard double mattress size—and the double bed mattress size you should shop for—is about 138 cm × 188 cm. Some bed manufacturers and retailers list a slight variation—around 138.5 cm by 190 cm—so it pays to double-check exact mattress specifications in centimetres rather than relying solely on the product label. When you are arranging a bedroom, those extra couple of centimetres can make a noticeable difference in a tight corner.

While shoppers in North America often use the term "full" to describe this exact footprint, Australian stores almost universally stick with "double". It serves as a middle ground between single setups and larger queen options, offering ample space for a solo sleeper or a cozy fit for two adults.
Keep in mind that bed frame dimensions are always broader than the mattress itself. A timber or upholstered bed frame will add outer width and length around the standard double mattress—for instance, Levede's Double LED Bed Frame with Gas Lift & USB Ports measures 204 cm in length by 155 cm in width.
Is a Double Bed the Same as a Full Bed?
When searching for sleep setups, you might encounter the term full bed size. Across most international furniture markets, full and double refer to the exact same physical mattress footprint.
While North American stores routinely list "full", Australian bed shops almost exclusively use "double". To avoid any confusion when shopping across different brands, simply check the mattress dimensions in centimetres before you buy.
Double Bed Width, Length and What Those Numbers Mean
Understanding double bed width and overall length helps you figure out how a bed actually functions in your room. A standard double bed width sits around 138 cm, which determines the shoulder room for sleepers. If you are asking how long is a double bed, expect roughly 188–190 cm; this double bed length dictates how comfortably a taller person can stretch out without their feet dangling off the edge. If you want to dive deeper into how various Australian dimensions compare, read more about bed sizes in Australia.
To put these numbers into context, a traditional single mattress is roughly 92 cm wide, while a queen bed jumps up to 153 cm. That makes a double bed roughly 46 cm wider than a single, offering a vast improvement for solo sleepers who like extra space.
However, remember that outer bed frame dimensions differ from mattress sizes. A padded headboard, thick footboard, or extended side rails will extend the overall footprint well beyond the base 138 cm width—such as Levede double metal or upholstered frame designs which typically extend the outer footprint to around 144 cm in width and nearly 197 cm in length.
Double Bed Size in CM, MM, Inches and Feet
If you are checking room plans or comparing international furniture specs, having quick unit conversions is essential. You can measure your double bed size in cm, or convert it to millimetres, inches, or feet depending on your tape measure.
| Unit System | Double Bed Width | Double Bed Length |
|---|---|---|
| Centimetres (cm) | ~138 cm | ~188–190 cm |
| Millimetres (mm) | ~1385 mm | ~1900 mm |
| Inches (in) | ~54.5 in | ~74–74.8 in |
| Feet & Inches (ft/in) | ~4 ft 6 in | ~6 ft 2 in |
Retail brands often round these figures slightly depending on manufacturing tolerances—a small variance in millimetres is completely normal across the bed industry. For a quick conversion, a standard double bed is roughly 1.38 m wide by 1.88–1.90 m long; these are the double bed measurements in metres most retailers work from. In Australia, centimetres remain the default standard for bedroom furniture layouts, so stick to cm when marking out your floor space with painter's tape.
Is a Queen Bigger Than a Double Bed?
When asking whether a queen is bigger than a double bed vs queen, the answer is a clear yes in both directions. A standard double mattress measures roughly 138 cm × 188 cm, whereas a standard Australian queen mattress comes in at 153 cm × 203 cm. That gives the queen an extra 15 cm of width and 15 cm of length.
| Bed Size | Mattress Dimensions (W × L) | Key Difference | Best Suited For |
|---|---|---|---|
| Double Bed | ~138 cm × 188–190 cm | Base compact layout | Solo sleepers, guest rooms, smaller spaces |
| Queen Bed | ~153 cm × 203 cm | +15 cm wider, +15 cm longer | Couples, taller sleepers, master bedrooms |
That additional 15 cm of length in a queen makes a massive difference for taller sleepers who find a double bed a little short. For couples, the extra width allows both people to sleep without feeling cramped.
However, a queen bed takes up significantly more floor area in a guest room or smaller apartment bedroom. If your floor space is limited and every centimetre counts, choosing a double bed can leave valuable clearance for bedside tables, wardrobes, and walk space.
Double Bed vs Single, King Single and King
Comparing a double bed vs single bed shows a substantial increase in width. A single sits at roughly 92 cm wide, meaning a double adds about 46 cm of extra sleeping area while keeping a similar overall length.
| Australian Bed Size | Width (cm) | Length (cm) | Comparison to Double Bed |
|---|---|---|---|
| Single | ~92 cm | ~188 cm | 46 cm narrower, same length |
| King Single | ~107 cm | ~203 cm | 31 cm narrower, 15 cm longer |
| Double | ~138 cm | ~188–190 cm | Standard baseline size |
| Queen | ~153 cm | ~203 cm | 15 cm wider, 15 cm longer |
| King | ~183 cm | ~203 cm | 45 cm wider, 15 cm longer |
When comparing a double to a king single, the trade-off shifts. A king single is narrower (~107 cm wide) but longer (~203 cm long), making it a great pick for tall teenagers or solo adults who need legroom rather than width. On the other hand, a standard Australian king bed measures approximately 183 cm × 203 cm—if you want to see how the largest options compare, explore this breakdown of king size bed dimensions. A king is vastly wider than a double, offering luxury space for couples—though it requires a much larger bedroom.
Note that in Australian retail contexts, a "twin" mattress usually refers to two single setups or a single mattress, not a double bed.
How To Choose a Double Bed for Your Room and Budget
Finding the right double mattress size involves looking at both your sleeping preferences and your bedroom layout. Before placing an order, measure your available floor space carefully, accounting for door swings, wardrobe access, and walking pathways around the mattress. Pair your new frame with a comfortable double mattress for a seamless fit. If you are matching a frame to a standard Australian double mattress, Levede's double bed frames are a practical place to start—just confirm the frame's stated mattress fit against the 137 × 190 cm / 138 × 188 cm range before you commit.
It is best to treat your mattress and bed frame as related but separate purchases. While standard double mattress dimensions fit any standard double frame, the total outer bed frame dimensions vary widely based on design a minimalist metal platform frame takes up much less room than an upholstered gas-lift bed with a thick headboard or built-in storage. If you are considering functional frame options, learn more by reading are gas lift beds worth it? or check out are storage beds worth it? An honest Australian guide.
When shopping in Australia, run through a quick buyer checklist:
- Access: Measure doorways, stairwells, and narrow hallways to make sure your new frame or mattress can be delivered without hassle.
- Storage: Decide if you need built-in storage drawers or a gas-lift mechanism to maximize bedroom organization.
- Sleepers: Determine whether the bed is for a solo occupant, a guest room, or two adults sleeping together every night.
